育苗圈“扛把子”！ 80歲大爺發明打缽機，成功解放了200萬勞動力【發明迷】

I have people in the countryside, their family of the kind of cotton planting vegetables are played without seedlings of the play without seedlings of the bacteria agronomy It will increase production and increase farmers' production but that's too much Could it be that this agriculture directly helps liberate us from the physical labor of prosperity This axis has been modified to form This is not the head of pressure pressure, this is back to the soil To this position he squeezes it, to this position he's going to push it back Squeeze each one down and put it on the seedbed, and the structure has lower failure force at a single point Open vegetables to this small nutrition pot with the 48 volt battery of the battery car is free from the greenhouse pollution The speed regulating arm is the same as the arm of your motor vehicle and then you plug this fork pin into it and it doesn't need a human being and it can do other things The auras are better and more plentiful You have a long way to go and we are proud to work hard and you and I are very happy hahaha
