摘要
通过不同的试验设计 ,3年间对风沙土进行秸秆等有机物料培肥 ,研究其几个主要肥力 (有机质、全氮肥、全磷 )的变化。结果表明 ,不同的有机物料培肥都能提高风沙土的肥力 ,但不同的有机物料对风沙土肥力贡献不同 ,其中以处理 (低量秸秆 +泥炭全肥 +泥炭 )
Three years experiments were conducted to study the effects of organic manure application on main fertilities(organic matter,cation exchange capacity,total N,total P)in wind blown soil.The results indicated that different organic materials could improve fertility of wind blown soil in different degree.The effect of stalk+muck+peat was the more effective than that of the other treatments.
