| 摘 要： | 通过对土壤酶活性、土壤微生物数量和土壤养分的分析,研究江汉平原上游10个县(市)杨树林下土壤肥力因子之间时空变化及其相互关系。结果表明:无论是林下相对于林外,还是生长季相对于落叶季,细菌数量与磷酸酶活性、真菌数量与蛋白酶活性总是正相关;而在杨树的生长季节,土壤AA含量与各类微生物数量均呈正相关;土壤NO3--N、有效Ca含量与各类微生物数量均呈负相关;Mg/K与真菌数量显著正相关;土壤NO3--N含量与有效B含量呈极显著正相关;有效Ca含量与有效Mg含量呈显著正相关,与Mg/K呈极显著正相关。

| Abstract: | In this paper,through the analyses of soil enzyme activities,number of soil microbes,and soil nutrients,the interrelations between fertility factors of soil under poplar forest in the poplar forests from 10 counties were investigated.Results showed that no matter forest areas related to non-forest areas, and growing season related to defoliation season,the following relationships were always being: bacteria numbers positively related to phosphatase activity;fungi number positively related to proteinase;whil... |
