通过使用除草剂果尔、禾纳斯、丁草胺及克无踪在主栽品种雪松、山杜英、山玉兰、五角枫当年生籽播苗圃及１年生移植苗圃，进行单用与混用试验，摸索出对苗木安全、除草效果显著的除草剂适宜浓度及使用方法。试验结果表明，苗圃使用化学除草剂除草，能大幅度降低育苗成本，提高经济效益，比人工除草节省用工８３６％，节省资金８０１％。 Through the use of herbicides such as Guer, Junius, Butachlor and Keweiqi, single-use and mixed-use trials of the main cultivars Cedrus densiflora, Shanmuying, Shan yulan, Perennial seedling nurseries and 1-year-old transplant nurseries were conducted A seedling safety, herbicidal effect of significant herbicides appropriate concentration and use. The results showed that the use of chemical herbicides in nursery herbicides can greatly reduce the cost of nursery and improve economic efficiency, saving labor by 83  6% compared with artificial weeding, saving 80  1%.
