摘要
于1985—1990年在黑龙江省松花江林业管理局所属9个林业局,使用化学药剂防除林木萌条进行调查研究,采用10m×10m样方,在根桩上涂沫不同的浓度药剂。试验结果:草甘膦+盖灌林各50％、草甘膦+绿草定各50％的混合配方,以1:9浓度为最佳药量;7月份是最佳时间;涂沫法和涂沫器是最佳方法和最佳工具。使用化学药剂操作简便、成本低、效果好,是进行营林生产森林扶育一种有效措施。
Experiments on eliminating stem sprouts by chemicals and investigations have been carried out by painting chemicals of various concentrations on the stems in 10*10 m plots in nine forest bureaus attached to Songhuajiang Forest Management Bureau of Heilongjiang Province from 1986 to 1990. The results show that the concentration of 1: 9 is the most suitable dosage for the mixture formula of Glyphosate+Garlin-520 and Glyphosate+Garlon-4, July is the most suitable time, and the painting method and the painting device are the best method and tool. It is easy to practice, low cost and good effects, and provides an effective measure for forest management and tending.
