注射竹,是指用竹腔注射法防治竹螟而被注射化学农药的竹子。该法具有操作简单、防治效果好、不污染环境,并适宜在高山密林中工作等优点。近年来,许多毛竹产区在竹子虫害防治中得到较广泛的应用。据嘉兴地区统计,1980年采用注射法防治竹螟面积达1万余亩。但在推广过程中,许多群众耽心注射化学农药后,是否会降低竹材的力学性质和使用价值。为此我们进行了注射竹力学性质的测定。现将初步结果整理如下。
Injection bamboo, refers to the injection bamboo shoots bamboo injection and chemical pesticides are injected bamboo. The method has the advantages of simple operation, good control effect, no pollution to the environment and suitable for working in the alpine jungle. In recent years, many bamboo producing areas have been widely used in bamboo pest control. According to statistics from Jiaxing, in 1980, the area of bamboo borer was controlled by injection to over 10,000 mu. However, in the promotion process, many people are worried about the injection of chemical pesticides, will reduce the mechanical properties of bamboo and use value. To this end, we conducted a determination of bamboo mechanical properties. The preliminary results are now organized as follows.
