自1964年广东省飞播马尾松造林获得成功以来,马尾松飞播造林,成林面积不断扩大,取得了可喜的成绩。但随之而来的是大面积的飞播马尾松林,因得不到及时的合理抚育间伐,林木分化严重,生长衰退。从生产需要出发,我们在1978~1984年开展了飞播马尾松林林分的生长调查及抚育间伐技术的研究,现将结果整理分析如下。一、研究方法为了掌握林分的特点,从1978年开始,先后到惠东、博罗、紫金等县,在现有飞播马尾松林中选取不同地点、不同密度类型、不同年龄、不同生长状况的林分,设置了29个临时标准地进行调查,并于1980年,在博罗县龙华林场进行了飞播马尾松林不同间伐强度的试验。该试验设在阿公岭山腰的同一坡面上(南坡),海拔240~320米,林分未受人
Since the success of aerial planting of masson pine in Guangdong Province in 1964, Masson pine aerial seeding afforestation, forest area has been expanding, and achieved gratifying results. But followed by a large area fly masson pine forest, due to lack of timely and reasonable tending thinning, tree differentiation, growth decline. Starting from the production needs, we conducted in 1978 ~ 1984 aerial seeding Pinus massoniana forest growth survey and tending thinning technology, the results are summarized below. First, the research methods In order to master the characteristics of the stand, from 1978 onwards, went to Huidong, Boluo, Zijin counties, the selection of the existing aerial broadcasting masson pine forests at different locations, different density types, different ages, different growth status Forest, setting 29 temporary standards to conduct the survey, and in 1980, Boluo Longhua forest farms were flying senescence different thinning test. The test is located on the same slope (on the southern slope) of the mountain ridge at Gongyuling, at an elevation of 240 to 320 meters,
