酶是一切生物化学过程的催化剂。土壤中进行的一切复杂生物化学过程,如有机质的分解,腐殖质的合成以及土壤养分的转化等,均与土壤酶有关。因此,土壤酶活性与土壤肥力有密切的关系。这方面的研究,愈来愈被国内外土壤科技工作者所重视。本文根据几年来对土壤酶的研究资料,阐述土壤 Enzymes are catalysts for all biochemical processes. All complex biochemical processes in the soil, such as the decomposition of organic matter, humus synthesis and soil nutrient conversion, are related to soil enzymes. Therefore, soil enzyme activity and soil fertility are closely related. The research in this field is paid more and more attention by soil scientists at home and abroad. In this paper, according to several years of soil enzyme research data, elaborating the soil
