摘要：对1年生长柄扁桃苗圃杂草进行了10种除草剂茎叶处理,结果表明:苗圃中的杂草以藜科和禾本科为主,所有除草剂处理对藜科杂草均有防除作用,14%草除灵、10.8%盖草能、12.5%拿扑净、48%排草丹、10.8%高盖+48%排草丹、12.5%拿扑净+48%灭草松、50%异丙隆对禾本科杂草的防效率较高,其中,50%异丙隆的杀草谱最广。48%灭草松和12.5%拿扑净+48%灭草松处理的杂草防效率高,但其对苗木的为害严重。高剂量10.8%盖草能和12.5%拿扑净处理下,杂草防效率达到了68%和56%,长柄扁桃苗未表现出药害症状,二者适用于长柄扁桃苗圃杂草的防治。
Ten kinds of herbicide with different concentrations were sprayed on the stems and leaves of weeds in a one-year-old Amygdalus pcdunculata nursery. The results showed that the Chenopodiaceae and Poaceae weeds domi- nated in the nursery, and all the treatments had effect in controlling Chenopodiaceae weeds, while the treatment with the formula of 14% benazolin, 10.8% haloxyfop, 12.5% sethoxydim, 48% basagran 48% basagran, 12.5% sethoxydim ＋48% bentazone and 50% isoproturon had better effect , 10.8% haloxyfop ＋ in controlling Poaceae weeds. The herbicide-controlling spectrum of 50% isoproturon was the widest, and the 48% bentazone and 12.5 % sethoxydim ＋48% bentazone treatment had the highest efficiency in weeds prevention, but both of them made seri- ous damage on A. pcdunculata seedlings. The prevention efficiencies of 10.8% haloxyfop and 12.5% sethoxydim were 68% and 56% under high concentration treatment, and the A. pcdunculata did not represent injury symptoms, so they are suitable for weed prevention in the nursery of A. pcdunculata.
