为寻找不同耕法最优组合，创造稻田良好的耕层结构和土壤环境，本文从不同耕法对稻田理化性状和水稻生长发育的影响及耕法后效等作为寻优指标，纵横比较各种耕法组合，提出了普（深）→少→少→普（深）的三年一周期的“二少一翻”的耕作组合系列
In order to find the optimal combination of different tillage methods and to create a good tillage structure and soil environment in paddy field, this paper from different tillage on the physical and chemical properties of paddy rice and rice growth and development and tillage efficiency as a superior index, Tillage combination, put forward the general (deep) → less → less → general (deep) three-year cycle of “two less than one turn” farming portfolio series
