Abstract
[Objective] The research aimed to study the effects of different factorial fertilizer on broad bean yield, water-stable aggregates and soil total organic carbon contents in irrigated farmland of Qinghai Province. [Method] The field plot experiments were carried out for three years in Northern district, Xining, Qinghai Province. [Result] The fertilizer treatments and check treatment had difference significantly on bean yield,and the rate ranged from 4.8% to 37.19%. Especially, the bean yield of organic and inorganic fertilizer treatment was the highest. The fertilizer treatments were helpful to improve the rate of >0.25 mm water-stable aggregates in some extents, lit could increase 1.5 to 3. 3 times than that of check treatment. So the fertilization with organic and inorganic fertilizer together could increase soil aggregates and soil construction. To compare wilh the check treatment, the rate of soil light fraction organic carbon ranged from 14. 19% to 202. 53% , and the rate of soil total organic carbon varied from 10.92% to 38.0% under continual fertilization for three years. [ Conclusion] Fertilization with organic and inorganic fertilizer together was useful for the soil fertility recovering and increasing.关键词
