摘要
研究了氮、磷、钾肥对油菜产量的影响,得出金沙县油菜施肥模型,结果表明:最优施肥方案为N肥10.7 kg/hm2、P肥7.5 kg/hm2、K肥6.0 kg/hm2,N∶P∶K配比为1∶0.7∶0.6,油菜平均产量可达2 250 kg/hm2以上。
The experiment in the model of fertilizer application in rape was carried out in Jinsha county and the. superiorly planning model of fertilizer application was obtained. The result was as follows： L0.7 kg N, 7.5 kg P, 6.0 kg K, and the. proportion of N： P： K was L ： 0.7 ： 0.6 so that the. average rape output may reech above 2 250 kg/hm^2.
