| 摘 要： | 以反枝苋、野燕麦、紫花苜蓿、多年生黑麦草等4种杂(牧)草种子为供试对象,用种子萌发法测定了筛选出的31种植物样品乙醇提取物的除草活性。结果表明,有24种植物样品对至少1种供试杂(牧)草种子幼芽和幼根的生长有90%以上的抑制作用,其中锦葵科野葵、大戟科蓖麻和葫芦科苦瓜等3种植物样品对供试的4种杂(牧)草种子幼根和幼芽生长的抑制效果均大于85%。

| Abstract: | The herbicidal activity of 17 families 28 genus 31 species plant samples was tested with the seeds of Amaranthus retroflexus,Avena fatua,Medicago sativa and Amaranthus paniculatus.The results showed that inhibiting rates of 24 kinds of plant samples were more than 90% at least to one kind of weed seeds.The inhibiting rates of M.charantia,M.verticillata,R.communis were more than 85% not only to young roots but also to young buds of the 4 kinds of seeds tested.In a word,the 3 kinds of plant samples had higher inhibiting activity to the 4 kinds of seeds,they were worth studying further. |
