| 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。

| Abstract: | 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. |
