对白浆土有机无机复合体进行了测定,阐述了有机无机复合体与土壤肥力的关系。白浆土原土复合量与有机质含量呈正相关,相关系数为0.9999;与全氮量的相关系数为0.9948;90%左右的磷是在有机无机复合体中。因此原土复合量可以做为白浆土的养分指标。原土复合量高的白浆土其结构性好。在三江平原的白浆土上,采用玉米、小麦秸秆还田,种植绿肥,增加土壤有机质,调节 C/N,提高腐殖质的活化度,可做为增加有机无机复合体,培肥土壤的一项根本措施。
The organic-inorganic complex of albic soil was measured, and the relationship between organic-inorganic complex and soil fertility was expounded. There was a positive correlation between the compound content of native soil and organic matter content in white soil, the correlation coefficient was 0.9999, the correlation coefficient with total nitrogen was 0.9948, and about 90% of phosphorus was in organic-inorganic complex. Therefore, the amount of native soil can be used as a nutrient indicator of albacore. Native soil high content of white clay its good structure. In the white soil of the Sanjiang Plain, corn, wheat straw returning to the field, planting green manures, increasing soil organic matter, regulating C / N and increasing the activation degree of humus can be used as an organic-inorganic complex to fertilize the soil Fundamental measures.
