本文侧重整理耕作方法与土壤养分关系的测实结果。一、耕作方法与土壤速效养分在插秧前和返青期,按处理取样测定耕层土壤速效氮磷钾含量结果(表1),旱少耕和免耕,比普耕在插秧前和返青期耕层表土速效氮磷含量略高。返青期稻株养分含量亦反映基 This article focuses on the measurement results of the relationship between tillage and soil nutrients. First, the tillage methods and soil available nutrients in the pre-transplanting and rejuvenation, according to the sampling and determination of topsoil available nitrogen and phosphorus content results (Table 1), less tillage and no-tillage than conventional tillage before transplanting and returning to green tillage Layer surface soil available nitrogen and phosphorus content slightly higher. Greening rice nutrient content also reflects the base
