通过田间小区试验,采用三因素五水平正交旋转组合设计,研究了红菜园土中氮磷钾肥配比对白菜硝酸盐含量和产量的影响.结果表明,能保证白菜产量为最高理论产量的60%～75%,同时控制其硝酸盐含量为1 600～2 100 mg/kg的最佳氮磷钾肥配比分别为150～180,23～65,92～173 kg/hm2.

A field plot experiment with orthogonalty rotational combination design with three factors and five levels was conducted to study the effects of N, P and K fertilizers on the yield of Chinese cabbage and its nitrate content in red garden soil. The results indicated that the optimun combination of the three fertilizers wa,; shown to be in the range of N 150- 180 kg/hm^2± 23-65 kg/hm^2＋K 92- 173 kg/hm^2, which gave 60%-75% the highest theoretical yie...
