| 摘 要： | 以蚕豆为绿肥,降低化学氮肥用量,对水稻的试验结果表明:以产量800.4 kg/666.7 m2的蚕豆作为绿肥时,化学氮使用量减少15%,即从常规的18.0 kg/666.7 m2减至15.3 kg/666.7 m2,水稻产量仍可达到585.56 kg/666.7 m2,比常规施肥增收51.65元人民币/666.7 m2,增幅为4.85%。

| Abstract: | The rice experiments of using horsebean as green manure and reducing chemical N fertilizer dose were carried out,and the results showed that when the horsebean yielding 800.4 kg/666.7 m~2 was used as green manure and the amount of chemical N fertilizer applied was reduced from 18.0 kg/666.7 m~2(conventional dose) to 15.3 kg/666.7 m~2,the rice yield could still reach 585.56 kg/666.7 m~2,which increased the income by 51.65 yuan/666.7 m~2 at a rate of 4.85%. |
