摘要
对来自国内外的4个紫花苜蓿Medicago sativa品种进行了“氰铵化钙”苗前除草剂的使用效果试验，主要对杂草的抑制率和增产效果进行了测定。结果表明，施用“氰铵化钙”对杂草有显著的抑制作用，尤其是对禾本科杂草抑制率均达69．7％以上；对各品种的增产效果也很显著，增产幅度达10．2％～28．2％，品种中以飞马的增产效果最明显。初步分析，“氰铵化钙”作为苗前除草剂用于苜蓿草生产，对苜蓿还有增产效果，因此值得推广应用。
The herbicide calcium hydro-ammoniation was used to control weeds before seeding 4 alfalfa varieties, the effectiveness in weed control and yield increment were tested. The results indicated that the herbicide could control 69.7% grass weeds and increase alfalfa yield by 10. 2%-28.2%. The variety ＂granduer＂ gave the highest performance. As an herbicide before seeding, calcium hydro-ammoniation is very effective for alfalfa production and should be further extended.
