【摘要】 <正> 土壤酶学的研究,从一开始便与土壤肥力的研究紧密地结合在一起。本世纪五十年代初,Hofmann提出了用土壤的酶活性作为衡量土壤的生物学活性和生产力的指标。其后,Lajudie与Pochon指出,根据土壤蛋白酶活性进行的分类,能较好地反映土壤的表观肥力。Moureaux在研究了许多土壤的转化酶活性后,也提出了类似的见解。Ky-更多还原

【Abstract】 With the duster analysis method, the role of the totality of soll enzyme activities in the evaluation of the level of soil fertility is discussed.Studies on black soil, meadow black soil and brown earth show that it is rather possible and feasible to evaluate the levd of soil fertility with the totality of soil enzyme activities.更多还原
