摘要
紫云英属于豆科黄耆属(Astragalus sinicus),是一种优良冬绿肥和优质青饲料,种植紫云英有省工、投资少、适应性广、产量高、肥效好、饲料品质优等优点,此外种植紫云英对促进土壤氮素循环、增加土壤有机质含量、活化土壤养分、节约能源、培肥地力、降低成本、改善生态环境等具有重要作用。紫云英高产栽培试验结果表明:紫云英的鲜草量与种植地块本身的土壤肥力密切相关,鲜草量随着土壤有机质含量的变化而变化,示范试验地紫云英平均鲜草产量为27 240 kg/hm2。该示范研究为从事紫云英研究与应用推广工作提供了理论依据。
Chinese milk vetch（Astragalus sinicus） is one of excellent quality green manure and green feed.Planting Chinese milk vetch has lots of advantages,such as labor saving,small investment,widely adaptation,high yield,rich fertilizer,high feed quality,and so on.Besides,it also had others important effects of promoting soil N recycle,increasing soil organic matter content,activating soil nutrient,saving resource,improving soil fertility,reducing the cost,improving ecological environment,etc..The results of high yield cultivation experiment indicated that the fresh grass yield of Chinese milk vetch was closely related with the soil fertility,and the fresh grass yield changes with the change of soil organic matter content.The average fresh grass yield of Chinese milk vetch in demonstrating test was 27 240 kg/hm2.These research results might provide some references for the research,spread and exploitation work of Chinese milk vetch.
