绿肥牧草对滨海盐渍土的改良作用研究进展

Research Progress on Improving Effect in Coastal Saline Soil of Green Manure Forage Grass

种植绿肥来改良土壤和培肥地力是我国农业生产上传统的养地措施之一。绿肥作为一种完全型肥料,在增加土壤有机质和矿质养分、促进土壤微生物的均衡发展和增强土壤酶活性方面具有显著效果。综述了具有一定耐盐性的绿肥牧草对滨海盐渍土壤盐分、p H、孔隙度、有机质、养分含量、根际微生物和酶活性等生理生化指标的影响,并提出了进一步研究方向。

Improving soil, culturing fertility by planting green manure was always one of the traditional measures of agriculture production in China. Used as fertilizer with complete type, green manure showed significant effect on increasing the organic matters and nutrients content of soil, promoting the balanced development of soil microorganism and enhancing soil enzyme activities. This paper reviewed the effects of green manure forage grass with some salt tolerance on physiologicul and biochemical indexes of eoastat saline soil such as soil salinity, pH value, poros- ity, organic matter, nutrients content, rhizosphere microorganisms, enzyme activities, and proposed further research direction about it.
