有机肥春施的主要缺点:早春温度低,表土干燥,肥料靠浅翻入土不能深施,甚至暴露在表面,肥效差,损失大。但结合秋翻地施用农家肥的优点:一是能与土壤充分混合,施肥深度也较适宜,能把肥料施到作物根层,便于作物吸收利用;二是秋季作物微生物活动旺盛,能使有机质有充足的时间腐熟分解,增加肥料的有效成份,提高肥料料利用率;三是秋施肥能使肥料在土壤中有较长的转化时间,改良土
The main drawbacks of spring fertilizer organic fertilizer: early spring low temperature, dry topsoil, fertilizer by shallow into the soil can not be applied, and even exposed to the surface, poor efficiency, loss of large. However, the advantages of combining autumn farmland manure: First, fully mixed with the soil, fertilization depth is more appropriate, the fertilizers can be applied to the root layer of crops for easy absorption and utilization of crops; Second, strong crop activity in autumn crops, can make organic matter Enough time to decompose decomposed to increase the effective ingredients of fertilizer to improve the utilization of fertilizer materials; Third, fertilizer can make fertilizer in the soil longer conversion time, improved soil
