有机肥——化肥配施对蚕豆的增产效应以及长期施用对土壤养分的影响

Affection of Broad Beans yield and Soil Fertility by Apply Organic and Inorganic Fertilizer

本文是全国试验网青海省长期定位试验的第17年的总结,主要研究有机肥、化肥及有机肥与化肥配施对蚕豆产量及土壤肥力的影响。结果表明,施用化肥、有机肥均能提高蚕豆产量,而NPK肥配合或有机肥与N、P、K配合时,才能获得更高产量,有机肥与P、K肥配施对蚕豆的产量影响也较大;通过土壤测试结果表明,施用有机肥和化肥均可明显提高土壤肥力。

The paper is the seventeenth year summary of fixed position experiments of fertilizer in Qinghai province network of whole country test in 1999. Organic and inorganic fertilizer be studied main that affect on yield of broad beans after them in prescription with each other. Experiments show that applied organic and inorganic fertilizer could increase the yield of broad beans. But chemical fertilizer applied in prescription or manure coordinate N、P、K could increase the yield remarkable. Organic coordinate P、K applied is also affect on yield of broad beans. The soil's measure result shows that applied organic and inorganic fertilizer obviously could increase soil fertility.
