沙打旺(Astragalus adsurgens Pall.)是多年生豆科牧草和绿肥,有抗寒、耐旱、耐盐、耐瘠薄、抗风沙、产量高等特性,近年在我国北方各地发展很快.但沙打旺在生长期较短的地区,种子成熟晚,产量低.1979年以来.我们围绕这一问题,在引种、选种及栽培方面进行了探索,初步认为下列措施可以促进沙打旺种子早熟并提高产量.一、整枝1981年,我们在乌鲁木齐市西郊本院实习农场对3年生沙打旺进行整枝试验,即于8月15日对植株打顶和打群尖(侧枝顶),
Astragalus adsurgens Pall. Is a perennial leguminous pasture and green manure that has the characteristics of cold resistance, drought tolerance, salt tolerance, barren resistance, sand resistance and high yield. In recent years, it has developed rapidly in various places in northern China. However, In the areas with short growing season, the seeds mature late and the yield is low.Since 1979, we have explored the introduction, selection and cultivation of this seed around 1979. It is preliminarily thought that the following measures can promote the early maturity and increase Yield, I. Pruning In 1981, we conducted a trimming test on the 3-year-old sand pollination in our internship farm in the western suburbs of Urumqi, that is, on August 15,
