| 摘 要： | 以德油8号为材料，研究不同氮磷钾施肥处理对油菜产量和经济效益的影响。结果表明，油菜施用氮肥的效果最好。氮、磷、钾施肥最高增产量分别达1582、467、133kg／hm^2，增产率分别为105．2％、19．3％、4．8％，纯增收入分别为3068、895、-288元／hm^2。根据拟合的肥效模型，确定油菜N、P2O5和K2O的最高产量施肥量分别为237．45、106．41和152．73kg／hm^2，最经济施肥量分别为201．84、77．28和0kg/hm^2.

| Abstract: | With Deyou 8 as the material,the effects of different fertilizer treatments with N,P,K on yield and economic benefit of rape were studied.The results showed that the effect of N on rape was the best.The highest yield gain of rape in treatments with N,P,K were 1 582,467 and 133 kg/hm2 with increasing rates of 105.2%,19.3%,4.8% and net income increase of 3 068,895,-288 yuan/hm2 resp.According to the fitted fertilizer efficiency model,the application amount of N,P2O5,K2O with the highest yield of rape was 237.... |
