大量研究证明,土壤中酶的分解作用,可使有机养分有效化,供作物吸收利用.与此同时,酶促进酚类物质氧化成醌,醌与氨基酸或肽缩合成腐殖酸.土壤酶活性反映土壤中进行的各种生物化学过程的动向和强度,是参与有机质分解合成的重要物质.国内外学者研究表明,土壤酶的活性可作为衡量土壤的生物活性和生产力的一项重要指标.在土壤肥力研究中,土壤酶的活性占有重要地位.1980年开始,我们在吉林省黑土区设置长期定位试验,试验处理分为不同数量的有机肥和无机肥配合施用.由于试验处理不同,施用的有机肥、化肥各异,导致土壤化学性状、粮食产量的不同,各处理间的土壤酶的活性也有一定的差异.本文拟以不同肥力黑土酶的活性与有机肥、化肥以及粮食产量的相关关系,作一初步讨论.
A large number of studies have shown that the decomposition of enzymes in the soil can make organic nutrients available for crop absorption and utilization.At the same time, enzymes promote the oxidation of phenols into quinones, quinones and amino acids or peptides to form humic acids. Reflect the trends and intensities of various biochemical processes carried out in the soil and are important substances involved in the decomposition and synthesis of organic matter.Studies at home and abroad show that the activity of soil enzymes can be used as an important indicator to measure the biological activity and productivity of soil. In the research of soil fertility, the activity of soil enzymes plays an important role.We started a long-term experiment in the black soil area of Jilin Province from 1980. The experimental treatments were divided into different numbers of organic and inorganic fertilizers.Due to the different treatment, Organic fertilizer and chemical fertilizer resulted in different soil chemical properties and grain yield, and there was also some difference in the activity of soil enzymes among treatments.In this paper, the relationship between the activities of soil enzymes and organic manure, chemical fertilizer and grain yield , For a preliminary discussion.
