环保酵素改良土壤系统的研究进展

Research Progress on Improving Soil System by Garbage Enzymes

环保酵素是以废弃果蔬、植物、厨余垃圾等为原料发酵制得的含有特定生物活性成分的产品,富含各种酶、有机酸、矿物质和微生物,是一种环保高效的土壤改良材料。总结归纳了近年来有关环保酵素对土壤系统中土壤理化性质、主要养分和土壤酶及微生物的影响方面的研究进展。提出的主要展望为:在发酵材料类型及其比例、方法的研究上有待更全面和深入,建立评估体系以利环保酵素的施用对土壤改良效果的长期评估;挖掘环保酵素对土壤系统中土壤理化性质、土壤养分、土壤微生物等影响的内在机理;探索土壤系统中各个生态因子的相互影响和联动影响机制。

Garbage enzymes are products containing specific biological active ingredients produced by fermentation with waste fruits and vegetables,plants,kitchen waste and other materials.They are rich in various enzymes,organic acids,minerals and microorganisms,and are environmentally friend and efficient soil improvement materials.The research progress on the effects of garbage enzymes on soil physicochemical properties,main nutrients,soil enzymes and microorganisms in soil system in recent years was summarized.The main prospects are as follows:to make a more comprehensive and in-depth research on the types and proportions of fermentation materials and methods;to establish an evaluation system for the long-term evaluation of the effect of garbage enzymes on soil improvement;to explore the internal mechanism of the effects of garbage enzymes on soil physicochemical properties,soil nutrients,and soil microorganisms in the soil system;and to explore the interaction and linkage mechanism of ecological factors in soil system.
