摘  要：
土壤中较稳定的固相部分,总是以各种大小不同,形状和特性各异的无机及有机颗粒相互组合而成。这种不同的组合和排列形式以及由此而造成的土体松板、孔隙状况、土块大小及其稳定性等特点总称之为土壤结构状况。它直接影响着土壤的水热状况,影响植

摘  要：
This article deals with the effect of different structure on the phosphorus fixation and nitrogen retention in some red soils. According to the results of the experiment, the relationship between the soil structure and the its nutrients supply and retention is discussed. Experiment results showed that the well-cultivated upland red soil and the fertile paddy soil of red earth with better structure were lower in fixation and higher in supply capability of phosphorus as compared with the infertile upland red soil and paddy soil of red earth with poor structure respectively. The NH4-N retention in well-cultivated upland red soil with better structure was more in quantity than that in the infertile upland red soil with poor structure and nitrogen in the former released more readily than that in the latter.
