Test on N P K fertilizer efficiency of rape
LAI Xian-hong
Abstract：A 3414 incomplete fertilization test on rape was carried out.The results showed that, the higher yield of rape were obtained in the treatments of combinative application of nitrogen, phosphorus and potassium fertilizer or combinative application of nitrogen and phosphorus.Furthermore, nitrogen had the most obvious yield-increasing effect, followed by phosphate fertilizer, but potash fertilizer showed none.And the output value was the highest by combinative application of nitrogen and phosphorus fertilizer with input-to-output ratio of 1∶ 5.99.
