为了给树木防病治病,人们早就有了给树打针的设想,因为用这种注射法较之通常使用的喷洒法,可减少对环境的污染,防止操作人员吸入农药,同时,还可大大减少用药量,节约生产成本。 前不久,澳大利亚的退休工程师杰夫·埃尔德里奇,研制成功了一种树木注射器。这种树木注射器,由标准的12伏手枪电钻改制而成,在原先安装钻头之处,装上了一种特殊的注射针。该注射针为中空,外有螺纹,它能钻入树干,并能由注射系统将小剂量的浓缩化学药剂注入树中。在注射针的前端,可以卡锁上插有6毫米钻头的白色塑料钻头座。 利用这种树木注射器给树打
In order to cure the diseases of the trees, people have long had the idea of injecting trees, because the injection method is better than the commonly used method of spraying, which can reduce the environmental pollution and prevent the operators from inhaling the pesticides. At the same time, Significantly reduce the dosage, saving production costs. Not long ago, Jeff Eldridge, a retired Australian engineer, developed a tree injector. The tree syringe, which was modified from a standard 12-volt pistol drill, was fitted with a special needle at the point where the drill was originally installed. The needle is hollow and externally threaded, drills into the trunk and injects small doses of concentrated chemicals into the tree from the injection system. At the front of the needle, a white plastic drill holder with a 6 mm drill bit can be latched. Use this tree syringe to hit the tree
