| 摘 要： | 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。

| Abstract: | The relation between organo-mineral complex and soil fertility had been investigated.The quantity of complex in the soil is directly pro- portional to the quantity of organic matter present in the soil,and its correlation coefficient r is 0.9999;the correlation coefficient of it to total nitrogen is 0.9948,and again 90% of total phosphorus are in organo-mineral form.We may conclude that the quantity of complex of the soil may be recognized as a nutritional index of the albic plan- osol,and the structure of ... |
