Effect of long-term use of organic manure and chemical fertilizers on fluvo-aquic soils physical quality

摘要: 通过长期定位试验研究了不同施肥处理对土壤物理性质的影响。结果表明，与单施化肥相比，施有机肥的土壤总孔隙度、土壤有效水含量、透水性、饱和导水率均较高，土壤持水性较好，表土硬度较低，改善了土壤物理性状，为提高作物水分利用效率和实施节水农业奠定较好的土壤条件。

Abstract: The influence of organic manure and chemical fertilizers on soil physical properties was studied. Results showed that organic manure not only increased the total soil porosity, soil water retention porosity, moisture retention capacity, effective water capacity, water permeability and saturated transmitting rate, but also decreased the hardness of surface soil. Organic manure can improve soil physical characters and bring about good soil condition for the practice of water-saving agriculture.
