| 摘 要： | 本文研究了几种肥料结构对鄂东南水稻土磷素供应能力和有机磷组分的影响。结果表明,土壤全磷、速效磷、活性有机磷和中度活性有机磷的含量,在长期只施化肥(包括磷肥)或本田绿肥沤清配合施用化肥(包括磷肥)的稻田位于低水平,在长期猪粪、堆肥还田配合施氮肥的稻田位于高水平。

| Abstract: | The influence of several fertilizer structures on phosphorus supplying power and organic phosphorus fractions of the paddy soil in the southeastern area of Hubei province was studied. The results indicated that average values of total P, inorganic available P,labile organic P, and moderately labile organic P in the soils applied by only chemical fertilizers(including calcium superphosphate) were on the low level;in the soils applied by chemical fertilzers (including calcium superphosphate) and green manure, also on the low level; but in the soils applied by N fertilizer, compost and pig manure, the values were on the high level. |
