在浠水县稻田进行了油菜“3414”的试验,研究氮、磷、钾肥施用量对油菜产量及效益影响。结果表明:平衡施用氮、磷、钾肥可显著增加产量和提高效益,且氮肥影响最大。综合考虑产量效益因素得出N、P2O5、K2O最佳施用量分别是10.3、4.3、5.1 kg/666.67 m2。
In the paddy field of Xishui County, rapeseed “3414” was conducted to study the effects of nitrogen, phosphorus and potassium fertilizers on yield and benefit of rapeseed. The results showed that the balanced application of N, P and K fertilizers could significantly increase the yield and benefit, and the nitrogen fertilizer had the greatest impact. Considering the yield and benefit factors, the best application rates of N, P2O5 and K2O are 10.3, 4.3 and 5.1 kg / 666.67 m2 respectively.
