Bọ trĩ gây hại bông sầu riêng như thế nào? Giải pháp quản lý độ ẩm chống rụng trái non (Đaklak)

Hello everyone. Today, I'm visiting Mr. Hai's durian farm in Buon Ho, Dak Lak. Mr. Hai has just started his harvest season. This is Mr. Hai's durian flower. Today, I'm going to share with you 2 main problems. The first problem is how to keep the water warm during the harvest season. To avoid the excess water that makes the flower dry. The next problem is how to manage the main crop at this time. Which is the corn. First, let's take a look at the thickness of the durian. Let's take a look. Here, some of the flowers have completely withered. We can see that the thickness of the flower is very good. There are many videos that I have shared with you about the thickness of the flower. Because the thicker the flower is, the more nutrients it has. The more energy it has, the easier it is to grow. The thinner the flower is, the more nutrients it has. Let's go back to the main topic that I have shared with you today. That is how to manage the crop at this time. Some of you have asked me what is the main crop at this time. Let me share with you. That is the corn. Here, let's take a look at the condition of the corn. As you can see, it is completely black. Today, I come back to this durian garden to share with you how to manage this corn. The number of flowers is not important. The most important thing is the corn. Because when the flower is blooming, it will attack the corn. As you can see, it is completely black. Let's take a look at the flower. As you can see, it is completely black. This disease is extremely important at this time. Because the number is small, it doesn't affect much. But if it is too much, it will directly affect the corn. After the crop is finished, it will turn black like this. And it is very easy to fall. It has a very heavy impact. So how do we manage this crop at this time? What do we do? As you know, the flowers are blooming. And we are in the process of fertilization and germination. We limit the use of pesticides. As you can see, the flower is blooming like this. If we use pesticides and let the water fall in here, it will damage the fertilizer. Even if we have water, it will damage the fertilizer. So my advice is that we should limit the use of pesticides when the flowers are blooming like this. But it doesn't mean we don't fertilize. Because at this time, the crop is severely damaged. If we don't fertilize, it will cause even more damage than if we fertilize. So my advice is that in special cases like this, when the flowers are blooming like this, you can see that the crop is completely rotten. We have to fertilize to eliminate this pesticide. At this time, we fertilize the pesticide to limit the situation when the flowers are hot. Limit the situation when the flowers are affected. Then we set up a way to fertilize cool pesticides. Cool, but strong. My brother shared that there are two types of pesticides. One is cyanobacteria. It is a pesticide that specializes in pesticides. Or we mix it with a pesticide to combine with cyanobacteria, which is a special pesticide. It is a cool, biochemical pesticide. We can fertilize to eliminate this pesticide, without affecting the flower. That's how we fertilize. And at this time, we can combine it with another harmful object, which is the fungus. Fungal fungus. We combine it with the pesticide, which is also cool, to prevent the insect from getting infected. Because at this time, the surface of the sugarcane is very wet. It's sweet. When it sticks to our durian flowers, it is very easy for the fungus to attack. As you can see, the surface of the sugarcane is very wet. This is the problem that will create a path for the insect to attack. Or the fungus will continue to attack when this flower starts to bloom. That's the problem inside the flower at this time. And if we manage it in time, we can fertilize it from 2 to 3 days, and eliminate, for example, 100%, but we can fertilize about 70-80%, and the number decreases to the maximum, it will not affect us much. And if we leave the surface too hard, too much like this, it will directly affect us, after it stops. So that's how we manage it inside. And the next problem, I will share with you about the outside solution. When we finish fertilizing the inside, and we leave it for about 7-10 days, when this flower is completely over 95%, we will fertilize it again. The distance from 7,000 to 10,000 is not far. Then we fertilize it again, fertilize it again, and we combine it with Calcibor to help the sugarcane roll, and we combine it with some care or deep water, so that we can fertilize it again, to help it spread, and eliminate the epidemic better. We don't do it in one go, we do it in 2-3 times, because when the flowers are over 95%, the disease will continue to attack. So when it comes to the outside solution like this, we have to pay attention to the object outside the leaf, not the leaf, which is the red thorn. Because right now the temperature is very high, the sun is strong, so the conditions are very good for the red thorn to hit the leaf, it will make it too hard. So when the red thorn hits too hard, it will make our leaves have a risk of turning yellow, it will lose the good effect. So this is Mr. Haeng's garden, it has some red thorns, it hits it, it makes our leaves turn yellow. So when we let it hit harder, the ratio of our leaves will lose the green color, slowly it will turn white, turn yellow, then it will lose the good effect, no more green. So when there is no more green on the leaf, it will not be able to combine. So when it can't be combined, it will not be able to combine nutrients for the red thorn. At that time, it will directly affect the red thorn, it will be easy to fall off. Pay attention. So we have to keep the green color of the leaf outside to make it combine with the sun, then it will be able to combine. It will make our flowers more beautiful, stronger, more round, and more green. At that time, we have to keep the green color. We have to spray the red thorn, at this time, we can't stop it, we have to spray it. With a spray gun, we spray it on the outside of the leaf. Let's spray this red thorn, it's very dangerous. If we let the red thorn hit too hard, if the leaf is too soft, it will fall off, it will fall off our leaf. If we let it hit too hard, it will fall off our leaf. It will fall off the leaf, it will affect our plant, we won't have the energy to grow flowers anymore. Pay attention. And at this time, we can combine the red thorn, we spray it on the outside, and we combine the anti-shock product, anti-heat, then the sun will directly hit the outer layers of our leaves, it will make the leaves like this. I can see, the positions where the leaves are covered like this, because of the sun, the high temperature in the afternoon, it directly hits the outer layers of the leaves, it will make the leaves yellow for a long time. Yellow leaves. We notice that at this time, we combine it with some products to help strengthen our leaves. The substance we can refer to is the substance that has a mild acetamin with the amino compound. Amino is an acetamin substance that helps stabilize the green color of our leaves. It is directly produced by the substance, it will stabilize the green color of the leaves. And in the amino compound, there is also copy, which is the medium that helps the leaves turn green. When it turns green, it will limit the sun's impact on our leaves. It makes the leaves yellow. So the problem of keeping the leaves green and green at this time is necessary with the amino compound. And we combine it with the Arifos. The Arifos is a 2-layer Calico leaf, imported from the Netherlands. We spray it at this time to make our leaves thicker. Because at this time, the thickness of the leaves will determine the ratio of nutrients to nutrients. We want our leaves to produce a lot of nutrient energy per leaf. We have to make it a certain thickness. Only then can it produce a lot of nutrients. It will be able to combine a lot. At this time, we use the Arifos product. It is also anti-inflammatory at this time. When we are about to attack, we put the Arifos in. The 2-layer Calico leaf will help prevent some of the pathogens from getting sick. After spraying the amino compound with the Arifos, at the next stage, if the leaves are thin like this, we can spray the Arifos. At this time, we focus on keeping the leaves green to make the leaves move better and run faster. That's how we manage the outside and combine it with the inside. That's an external product. We will go to 1-2 more trees. I will share with you how we manage nutrients below at this time. After the leaves start to rot completely. In general, the durian garden has a very fat stem. The old leaves are also very solid. There are not many pathogens. We keep it at this time very well. But at this time, we see that the stem is fat and stable. It doesn't mean that it has a lot of beans. If we leave it in excess water during the germination stage, if we leave it in excess water and water it a lot, it will boil up and open the stem immediately. As you can see, if we look down at this position, this is the problem of the germination of durians with Mr. He. Now, Mr. He is watering. As you can see, there is a slight excess of water here. Watering during the germination stage does not need to water too much. If you water too much, it will boil up and it will go into a group of strong pods. It is very difficult to stop. The stronger it is, the more nutrients it will retain. At this time, the inside of the flower will be affected. Therefore, at this time, to balance the nutritional system, such as water in the tree, we just need to water lightly. Watering lightly here depends on the conditions of our soil. The soil is in the position of our soil. We water to keep it moist. If we want to maintain the moisture level from morning to dusk, we still have a little moisture, not dry, we should water in the morning. We water at 5-6 o'clock. At that time, the condition of our soil is even, it is cool, it is not dry, it is not dry. The second problem is that we water in the morning, our soil is still cold, it is still stable, it is not hot. We water in. We watch the amount of water, we water appropriately. For example, we water the bed system, we water about 20-50 minutes depending on the soil. And depending on the size of the bed, we have to watch. However, we do not recommend exactly how much water we water, because each bed is different. And the layout of the large and small watering systems is different. Here, we only advise our children to watch according to their soil position, we water moderately. When we finish watering in the morning, by noon, our soil is still moist. Because we water in the morning, by noon, the soil is still moist. At this time, the sun shines down, the roots are not damaged much. Because we have watered in the morning, by noon, the soil is still moist, so it is very suitable. By the afternoon, our soil is still slightly moist, it does not affect our roots. At this time, we will maintain a stable system of moisture from noon to afternoon. And the next day, we see that if our soil is still moist, we do not water. The next day, the next day we water again. And if our soil, we water today, the next day, we see that our soil is too dry, we water again, continue in the morning, every day, every watering. Here, Mr. Hai watered on the right day, but Mr. Hai watered a little too much water. We notice, if we keep watering, we water a lot like this, to the point where it shows 100%, then surely the amount of water below will rise. It rises, it will make the roots, the roots of the roots, the excess water, it will fall very hard, especially this Durian tree. We notice, here is the area of Dak Lak, in the South, so we definitely have to water more water than in the West. But how much we water is not suitable, is a necessary issue. We have to review. And the way we water does not mean that we just concentrate on the roots and there is enough water. Because our roots absorb water, it accumulates here. It lies from the Durian tree, as you can see, from here, from the feet we stand here, and to there. And the amount of roots it accumulates here is a lot. So if we water correctly, we have to water from the roots about 1 meter, then we water to here, that's right. And if we water just focus on here, we have to water We concentrate here is not the right way to water. Then we leave it dry here. If we leave it dry here, the roots will be burnt. Because it's too dry, in the afternoon, it will fall down and burn the roots. It will damage the roots. On the top, it will be very strong when it falls down. That's the problem that a lot of our children forget to notice. We notice that problem. So that's how we manage it. There are a lot of clips we share about how to water. And if we water a little, we should plant it outside a little to let the water come out here. If we plant it here, then the water will only come out here. It will be wet here. We notice that problem. And how do we water to make it suitable? You see, there are a lot of wood leaves in here. At this time, the wood leaves in here, we should dig them out. You see, we should dig the wood leaves out. And the pollen, the flower, it falls down here. It grows, we dig it out. If we leave it here, layer by layer, and the wood leaves are so many, then the water will keep the water a lot. And if it keeps the water a lot, it will make it moist, so it will be easy to grow. So at this time, we should dig it out. Dig it out. We are not afraid that the sun will burn the roots. Because in here, there are trees and it's cool. So we should dig it out. It will help to clear the roots, clear the roots. When the oxygen goes down to the roots, it will be very strong. It will help our fruit to grow very fast. And outside, we don't have a greenhouse. So if it's sunny at noon, the roots will burn easily. So we should keep the grass. Here, you see Mr. Hai has grass. We should keep the grass like this. If we dig all of this grass, it will be very empty. If there is no grass, at noon, the sun will come down and it will burn the roots. It will affect the fruit inside. So if we can keep the grass, it will help to maintain our moisture and keep the fruit inside. So we let the grass help the lotus to create the soil conditions. We will have the soil to develop the roots very fast. So that's how we manage the grass. If it's too we can dig down like this. If it's too high, or very high, we can dig down like this to help by watering every other day, but we reduce the amount of water in the morning in the second half of the spring. I will share the next issue with you later. At the same time, we have to immediately address the issue of waste management to avoid a direct impact on our crops. That's the solution I'm going to share with you today. In the process of doing it, each use will be different. The way we manage the water and the way we manage the drought will be very different. At this stage, we have to eat less and more vegetables. This is very important. First, we have to ensure that the water is warm and we have to water it appropriately. Second, the nutrition at this time is declining. The decline in the state of the tree. The strength of the tree will determine the health of the tree. The more leaves, the more beautiful leaves. If our tree grows well, we will definitely have a lot of benefits. We have to limit the number of leaves. Because if the tree is too strong, it will be easy to lose leaves. Therefore, we have to limit the number of leaves. Combine with light water and no water, then the healthy tree will produce a lot of fruit. If at this time, our tree is damaged, the leaves fall, the leaves fall, then it will definitely fall a lot of flowers. Because the tree is too damaged, it does not have enough nutrition to grow, then it will definitely fall a lot of flowers. And the next issue is that if we can determine the state of the tree at this time, then it is meaningless for us. We have to train 12, 11, 18, or 3 numbers, or we have to train a machine. Maybe at this time, it is not effective. Because we know that at this time, it will take about 7 to 10 days to finish. We see this. We come here and we see this tree. You see, when it blooms, it grows very fast. At this time, if you ask whether it can be divided or not, we advise that at this time, it will fall a lot of flowers. At least because of the problem of the tree. If the stem is fat, it retains a lot of nutrition, then it will fall a lot of flowers. The leaves outside are green and shiny like this, they don't fall off. The leaves are green and shiny, they don't fall off. If the tree is healthy, then it will fall a lot of flowers. Combine with the problem of using moisture, as I said earlier. And if we divide it at this time, when we train the seedling, we train the seedling for at least 5 to 7 days. In the case of healthy trees, we train the seedling for at least 5 to 7 days, it will eat that seedling. To eat the seedling, the tree will be fat and fall a lot of flowers. So it doesn't play a decisive role in supporting the fruit. And if our tree is damaged, we put the leaves in for at least 10 to 20 days, then how can it bear fruit? In the case of healthy trees, it will definitely get a lot of leaves. If we leave the leaves out, it won't bear fruit. But the more we leave the leaves out, the more it will be damaged. Because it can't absorb it. If it's too weak, it can't absorb it. So at this time, we also support the middle part. Inside, outside the leaves, support the leaves. Harmful areas are fine. The lower part, combine with moisture, is fine. We don't need to deal with much. We don't need to leave the leaves out. If we bring the leaves in, we don't have to spend money. Until the time when it shows signs of bearing fruit, the fruit is stable. When there are fruits or seeds, we usually put a few seeds in to help it bear fruit. That's when it's suitable. At this stage, we don't need to leave the leaves out. Today, I just shared with you some of those solutions so that we don't have to deal with the situation where the leaves are too weak, or the problem that our flowers are weak or fat. We have a way to deal with it. As you can see, this tree has a lot of water. It's sunny, but it's not dry yet. There's a lot of water left. That's the solution I shared with you today. And you can see the leaves again. It's black here. If we don't cover it, it will turn white. You see, we have to cover it. It doesn't affect much. Because when there are flowers like this, it will definitely affect our flowers. If we don't cover it, the leaves will damage our flowers. So we have to cover it. That's the solution I shared with you today. If you have any questions, please contact me. I will support you. I wish you success.
