摘要
文章介绍了林业苗圃化学除草技术 ,包括针、阔叶树种苗木及不同苗期除草剂的种类、配方选择 ,作业时间 ,施药方法等。特别对带壳出土苗木和不带壳出土苗木对药剂的安全性研究有创新。通过系列应用试验证明 ,林业苗圃化学除草率可达 90 %以上 ,对苗木无不良影响 ,且有一定的促生作用 ,与人工除草相比 ,节省成本 93%以上 ,产效期延长 10～ 15d以上。
The paper introduced the chemical weeding technology in forest nursery, including the selection of herbicide kinds and formulation, application time and methods. Especially, a new observation was found in the experiment: some species of seed have shells when it was germinate, so the herbicide are very safe to their seedlings. Series of experiment results showed that the chemical weeding rate was up to 90%, all the herbicides have little damage to seedlings, even can remote its growth. Compare to the hand weeding, chemical weeding can save above 93% cost, the work-effort period are prolonged 10～15 days or more.
