在花生产区设置13个田间试验并测定土壤有效养分。结果表明,花生施钾肥的效果与土壤有效钾含量极不显著,而与土壤有效磷含量呈明显的正相关关系。采用逐步回归法统计结果,说明花生增产应强调钾与磷素营养的协调。根据回归方程算出,本区花生钾肥应用于缺钾区,亩施
Thirteen field trials were set up in flower production areas and soil available nutrients were determined. The results showed that the effect of applying K fertilizer on peanut was not significantly different from that of soil available K, but positively correlated with available P content. The results of stepwise regression analysis showed that peanut production should emphasize the coordination of potassium and phosphorus nutrition. Calculated according to the regression equation, the area of ?? peanut potassium applied to the potassium deficiency area, Mushi
