Mechanical deep plowing is a technical measure for increasing production in agriculture. Sun Xianzhuang Sun Zhuang Sun Suncun farmers Sun Xianbin, 1986 conditions in the same land for deep plowing and shallow plowing comparison test. 4.8 acres of wheat fields plowed 20-25 cm, yielding 360 kg of wheat; 3.8 acres of wheat fields shallowing 10-15 cm, yielding 300.5 kg of wheat. Farrowing than shallow farming acres yield 59.5 kilograms, increase rate of 20%. According to the relevant departments of the test and production practice shows that mechanical deep plowing than the general increase of 15-20%. The main reasons for the increase are the following points:
