| 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。

| Abstract: | 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 dominated 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, 10.8% haloxyfop+48% basagran, 12.5% sethoxydim+48% bentazone and 50% isoproturon had better effect 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 serious 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. |
