【Abstract】 Traditional farming system with a plough has restricted the development of agriculture in our country. By analysing technique of the soil deep loosening, it was found that the technique overcome the malpractice of the Traditional farming system,and could make crops grow, and could prevent from water and soil erosion. By studying the work principal of sabsoilers and field experiment, it was demonstrated that among subsoilers, function of bulk subsoilar is superior to else types subsoilers. The bulk subsoilor was good subsoiler when it worked in protecting farming of our country.更多还原
