摘要
夏收后耕地复种牧草对耕地生产效能影响研究的结果表明,复种箭竹舌豌豆和毛苕子可多生产青绿饲料24 382.5、23 787.0 kg/hm2,提高土壤有机质2.6、3.5 g/kg,提高土壤速效氮7.1、6.2 m g/kg,增加后作产量15.6%、16.3%,增收2 869.74、2 805.57元/hm2,能够显著的提高耕地生产效能。
The test of multiple cropping forage plant after summer harvest was conducted in Baiyin city of Gansu province. The results showed that multipling Vicia sativa and Vicia villosa could produce green fodder 24 382.5,23 787.0 kg/ hm^2,increase soil organic matter 0. 26,0. 35 g/kg,improve soil rapidly available nitrogen 7.1,6.2 mg/kg,increase the yield of succeding wheat 15. 6%, 16.3% and income 2 869.74,2 805.57 yuan/hm^2. The results showed the production ability of cultivated land could be increased remarkedly through the technique.
