沼肥特性及其在绿色蔬菜生产中的应用

Biogas Fertilizer Characteristics and Application in Green-vegetables Production

绿色蔬菜的生产准则为不用或少用化学肥料、化学农药和其它化学物质,施用的肥料应能促进蔬菜的生长、提高品质,不造成蔬菜产生和积累有害物质,对生态环境无不良影响。实践表明,利用沼液、沼渣作为蔬菜的肥料与防治病虫药剂使用,可减少化肥和农药的施用量,提高蔬菜的产量和品质,是生产绿色蔬菜的理想方法。该文在介绍沼液、沼渣主要组成与特性的基础上,详述了其在绿色蔬菜生产中的应用技术。

Green-vegetables production criteria：no use or little use chemical fertilizers,chemical pesticides and other chemicals.The growth and quality of vegetables should be been improved,and it can not produce and accumulate the harmful substances and no adverse effects on the ecological environment when the fertilizers to be used.Practice shows it is the ideal way to produce green-vegetables,when the biogas liquid and residue will be used as fertilizer and pharmacy to prevent the green-vegetables from diseases and pests so could reduce the fertilizer and pesticides,and the yield and quality of vegetables will have improved in all.This paper describes the application in green-vegetables production based on the main composition and characteristics of biogas liquid and residue.
