| 摘 要： | 在油松育苗中应用除草剂灭草效果明显，当苗木出土6～8周以后，用除草醚（1．1g·m^-2）、拿捕净（0．05mL·m^-2）＋果尔（0．05mL·m^-2）、除草醚（0．55g·m^-2）＋果尔（0．05mL·m^-2）分别进行土壤喷施处理，除草率达到96．8％、98％、99％。一定剂量的除草剂混用可增加有效期和除草率。施用除草剂对苗木不同时期生长无影响，且较为经济，每年可节约除草费用900～1200元·hm^-2。

| Abstract: | The effect is significant to clear of weeds in seedlings-raising of Pinus tabulaeformis by using herbicide;soil spraying treatment were conducted by nitrofen(1.1 g·m-2),sethoxydim(0.05 mL·m-2)+ oxyfluorfen(0.05 mL·m-2),nitrofen(0.55 g·m-2)+ oxyfluorfen(0.05 mL·m-2) respectively after emergenced for 6-8 weeks;weeding rate reach 96.8%,98%,99%,respectively.A certain doses of mixture of herbicide can increase period of validity and weeding rate.Application of weeding,which is economic,have no effect on growth of seedlings in different stages.The weeding cost can be saved by 900-1 200 Yuan ·hm-2 per year. |
