华山松是我省的主要造林树种之一。解放以来,营造了大面积华山松人工林,现已郁闭成林,长势良好。由于初植密度大,树木纤细,严重影响林木速生、丰产、优质,因此,抚育间伐已成为当前生产上必须解决的问题。为此,我们先后在曲靖地区、红河州和昆明市的10多个国营林场,进行了人工林的抚育间伐调查和试验工作。并编制成了“华山松人工林抚育间伐技术方案”。由于水平有限,存在问题不少,请有关部门给予批评指正,使本方案更加符合生产实际。
Huashan pine is one of the main afforestation species in our province. Since the liberation, Huashan pine plantation has been built in a large area. Due to the high planting density and thin trees, which seriously affect the fast-growing, high-yielding and high-quality trees, tending thinning has become a problem that must be solved in current production. To this end, we conducted surveys and experiments on tending of artificial forests in more than 10 state-owned forest farms in Qujing Prefecture, Honghe Prefecture and Kunming City. And compiled into a “Huashan pine planted tending thinning technology program.” Due to the limited level, there are a lot of problems, so that the relevant departments should be criticized and corrected to make the program more in line with the actual production.
