豆科绿肥及牧草的种类很多,分布很广。但目前在我区真正大面积应用于生产的主要有蚕豆、豌豆、雪扎、小扁豆以及箭舌豌豆几种。其次还仃小面积种植的黄花草木栖、紫花苜蓿、红豆草、沙打旺等豆科牧草。它们的培肥改土效果以及在农业生产中的综合生态效应,早已被生产实践所证实。因此,加强豆科绿肥品种的固氮能力,及其利用研究,重视绿肥作物的生产与发展,对提高土壤肥力,改善农田生态,促进农牧业生产的稳步发展具有重要意义。
Legumes green manure and many types of grass, is widely distributed. However, there are currently mainly used broad beans, peas, snow peas, lentils and arrow-tongue peas in our region. Followed by the small area planted yellow flowers Habitat alfalfa, alfalfa, safflower, sand and other legume forage plants. Their fertilization and soil remediation as well as the comprehensive ecological effects in agricultural production have long been confirmed by the production practices. Therefore, it is of great significance to enhance the nitrogen fixation ability of legume green manure varieties and their utilization research, attach importance to the production and development of green manure crops, and improve soil fertility, improve farmland ecology and promote the steady development of agriculture and animal husbandry.
