| 摘 要： | 在我国南方红壤中加入不同的磷活化剂进行培养试验,结果显示:磷活化剂提高了土壤有效磷含量,不同活化剂的活化能力不同。相关分析和通径分析结果表明,磷活化剂的活化能力大小顺序为:低分子有机酸钠钙盐>腐植酸>腐植酸钠>脲基甲酸乙酯;磷活化剂可以提高红壤中的Al-P、Ca-P和Fe-P等无机磷含量,其中Al-P和Ca-P与有效磷均达到极显著水平,而Fe-P作用效果不显著,可以通过影响Al-P和Ca-P来间接影响有效磷,磷活化剂会抑制土壤中O-P的生成。 |

| Abstract: | Different phosphorus activators(PA) were added into southern red soil of China to test their activation capability.The results showed that PA could improve available phosphorus contents in the soil effectively,and activations capability of different activators differed.Results of coeffcient analysis and path coefficient analysis showed that the activations capability order were as follows:Low-molecular weight organic acid>humic acid>sodium humate>ethyl allophanate.Meanwhile,PA could improve Al-P,Ca-P,Fe-P a... |
