摘要
对上海市奉贤区不同地块进行了小麦不同氮、磷、钾施用量试验,并建立了不同肥料施用量与产量关系方程。结果表明:奉贤地区小麦氮、磷、钾推荐施用量分别为240、120、48 kg/hm^2。
The field experiments with wheat were carried out in different plots under different N, P and K fertilizer rates, and the relations between fertilizer rates and wheat yields were statistically analyzed. The results indicated that the recommended rates of N,P and K fertilizers applied to wheat fields in Fengxian District were 240,120 and 48 kg/hm^2 , respectively, according to the present prices of fertilizers and the principle of reducing environment pollution.
