| 摘 要： | 大家都知道,有机物质有改土培肥的作用,但其中过程十分复杂,一般对氮素供应方面的研究较多,有机物质改善土壤团聚性和供肥保肥性的研究较少.本文拟就稻草、紫云英对黄棕壤和红壤的有机无机复合体性质的影响进行初步研究,并用氨化风化煤与聚乙烯醇作对比.

| Abstract: | This paper deals with the influence of application of rice straw,milk vetch,weathered coal and polyvinyl alcohol on the properties of organo-mineral complexes of yellow-brown earth (collected from Jiangning) and red earth (collected from Jinxian,Jiangxi).The results obtained are summarized as follows:In the yellow-brown earth,the polyvinyl alcohol and the nce straw were conduave to the formation of aggregates and thus increased the percentage of effective pore spaces of 0.1-0.01 mm.The polyvinyl alcohol treatment could promote the stability of aggregates.In the red earth,the rice straw and the milk vetch might cause dispersion of the aggregates.In above two soils,the treatment of ammonical weathered coal caused highly dispersion of aggregates. |
