通过3年5个田间试验,获得各处理油菜籽产量和N、P、K肥料利用率,依据养分平衡法的测土施肥公式,寻求各因子与土壤有效养分测定值的数量关系,最后提出以土壤有效养分测定值为自变量的油菜推荐施肥量等式。
Through three years and five field trials, the rapeseed yield and N, P and K fertilizer utilization rate of each treatment were obtained. Based on the soil fertilization formula of the nutrient balance method, the relationship between the factors and soil available nutrients was sought. Finally, Soil available nutrients measured as independent variable rape recommended fertilization equation.
