不同比例控释氮肥与普通氮肥对小麦产量影响研究

Effects of Controlled Release Nitrogen Fertilizer and Common Nitrogen Fertilizer in Different Proportions on Wheat Yield

研究不同比例控释氮肥与普通氮肥对小麦长势、群体构成、产量性状的影响,结果表明:在相同地力条件和栽培管理下,控释氮肥与普通氮肥比例为80∶20时,小麦产量最高,达到6 286.9 kg/hm2,可有效降低肥料成本。

This paper studied the effects of different proportions of the controlled release nitrogen fertilizer and common nitrogen fertilizer on wheat growth, population and yield traits. The results showed that with same soil fertilty conditions and cultivation and management, the wheat yield was the best when the ratio was 80∶20. The per unit yield could reach 6 286.9 kg/hm2, and the fertilizer cost could be effectively reduced.
