摘    要:通过12年长期定位试验研究了有机-无机肥料配施对土耕层土壤有机质、全氮、全磷、全钾、速效氮、速效磷、速效钾以及土壤的容重、田间持水量、土壤孔隙度的变化。结果表明,化肥配施秸杆与有机肥均能提高土壤肥力,但效果不同;与长期施无机化肥的NPK相比较,M(H)NPK、M(N)NPK培肥效果明显好于SNPK,以有机质提高最为显著。

关 键 词:有机物料  培肥    长期定位试验

Abstract:A long-term fertilization trail at the fixed site field was conducted for twelve years since 1990, aiming to research the effect of long-term application of organic manure and chemical fertilizers on main fertilities (organic matter, total N, total P and total K, readily available N, readily available P and readily available K,bulk density, moisture capacity and porosity) in topsoil of loess soil. The results indicated that different chemical fertilizers with organic materials could improve fertility of loess soil in different degree. The treatments of M(H)NPK and M(N)NPK were more effective than SNPK and were characterized by significant increase of organic matters.
Keywords:soil nutrition  land productivity  loess soil  long-term fertilization trail
