| 摘 要： | 根据黑土肥力的实验特点及前人研究成果,选取与养分和理化性质相关的10个评价指标,包括有机质(SOM)、全氮(TN)、速效磷(AP)、速效钾(AK)、阳离子交换量(CEC)、酸碱度(pH)、容重(BD)、黏粒(CP)、>0.25mm水稳性团聚体(WSA>0.25)和分散率(DR),通过这些指标建立了新的黑土肥力质量评价体系。以该评价体系为参照,采用主成分分析法确定权重,运用可拓学理论对吉林省农业黑土的肥力质量进行综合评判。结果表明:WSA>0.25、BD和AP 3项指标权重最大,说明黑土肥力的主要限制因子可能为土壤的物理性质及有效磷肥含量;吉林省农业黑土的肥力质量以中等为主,占整个样品数的73%。

| Abstract: | According to the fertility experimental characteristics of black soil and the results of previous studies,the fertility quality evaluation system of black soil is established by selecting 10 evaluation indicators including organic(SOM),total nitrogen(TN),available P(AP),available potassium(AK),cation exchange capacity(CEC),pH,bulk density(BD),clay(CP),the water stable aggregates which are great than 0.25 mm and its dispersion rate(WSA>0.25) Referring to this system,principal component analysis method is use... |
