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1 582、467、133 kg/hm2,增产率分别为105.2%、19.3%、4.8%,纯增收入分别为3 068、895、-288元/hm2。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152.73 kg/hm2,最经济施肥量分别为201.84、77.28和0 kg/hm2。
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 t 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, P2 O5, K2O with the highest yield of rape was 237.45, 106.41 and 152.73 kg/hm^2 resp. and the most economical application amount of them was 201.84, 77.28 and 0 kg/hm2 resp.
