摘要
采用培养皿滤纸的生物检测方法对红三叶、白三叶和紫花苜蓿 3种常用豆科牧草的化感作用进行了初步研究。结果表明 :3种豆科牧草在一定的播量下 ,对萝卜、青菜、番茄等受体植物生长表现出明显的抑制作用 ,使发芽率、苗长、根长、苗干重、根干重明显比对照降低 ,且抑制作用的强弱与豆科牧草种子播量有关 ,说明 3种豆科牧草均存在较大的化感作用潜势。
The allelopathy of red clover, white clover and alfalfa were preliminarily studied using the biological detection method of culture dishes with filter paper The results showed that the three legumes under a certain sowing rate were significantly inhibited the seedling growth of radish, green grocery and tomato, the germination percentage, seedling length and weight were obviously declined The inhibition degree was related to legumes seed sowing rate Anyway, the three legumes have strong potentiality of allelopathy
