在云南省镇沅县勐大镇西山村100 hm2原采伐迹地上进行思茅松模拟飞播造林,由于在幼林期间,疏于管理,管护力度不够,再加之周边地区牲畜等的践踏和病虫害危害严重,导致了杂草较多,影响了思茅松林木的正常生长,林相稀疏,生长速度滞缓。镇沅县林业局于2002年投入了一大批人力、物力和资金,对此地块进行思茅松丰产栽培试验,本基地位于海拔1 300~1 400 m,土壤肥沃,阳光充足,为思茅松的生长营造了良好的环境。基于此,重点来分析一下思茅松丰产栽培试验,探讨思茅松丰产栽培技术以及林木相关管理工作。
Simulated aerial sowing afforestation on Pinus sylvestris var.mongolica on the 100 hm2 original logging site of Xishan Village, Mengda Town, Zhenyuan County, Yunnan Province. Due to lack of management and management and maintenance, the management and protection of Pinus sylvestris var. , Resulting in more weeds, affecting the normal growth of Pinus kesiya trees, sparse forest, slow growth rate. Zhenyuan County Forestry Bureau in 2002 invested a large amount of manpower, material and financial resources, the plots for Pinus kesi pine cultivation test, the base is located at an altitude of 1 300 ~ 1 400 m, fertile soil, plenty of sunshine, as pine Growth creates a good environment. Based on this, the key point is to analyze the high-yielding cultivation experiment of Simao pine and discuss the high-yielding cultivation techniques of Simao pine and related management of trees.
