摘  要：
采用环状沟施、穴状施、两侧沟施3种方式,对普洱市思茅区万掌山林场山地(缓坡地和斜坡地、陡坡地)上种植的3年生思茅松幼林,进行同等剂量混合肥[(尿素100g+过磷酸钙150g+硫酸钾80g)/株]施肥的双因素随机区组试验。结果表明,不同施肥方式、坡度间对思茅松幼林树高、地径和冠幅的生长影响差异不一,施肥方式和坡度间不产生交互作用。缓坡林地和陡坡林地施肥,穴状施肥的方式对林木生长的效果最好;斜坡林地施肥,环状沟施效果最好,其次是穴状施肥。综合考虑不同施肥方式的施工成本和生态效益,思茅松山地林木宜采用穴状施肥,对树木周围的土壤开挖面小,有利于保持水土,减少林地水土流失,同时穴状施肥用工量少,可节省大量的劳力成本,在生产实践中可操作性强。

摘  要：
A two-factor randomized block experiment was conducted on 3-year-old Pinus kesiya var.langbianensis young forest planted on Wanzhangshan Forest Farm mountainous area(steep slope,gentle slope and slope) in Simao District of Puer City by using four-point fertilization method,circular ditch fertilization method and bilateral ditch fertilization method.The results showed that different fertilization methods and gradients could be used to fertilize the same amount of mixed fertilizer [(urea 100 g+calcium superphosphate 150 g+potassium sulfate 80 g)/plant].The growth of height,ground diameter and crown width of young Pinus kesiya var.langbianensis forest differed from each other,and there was no interaction between fertilization methods and slope.Fertilizer application in gentle and steep slope woodlands had the best effect on the growth of trees by using four points method,while fertilizer application in circular furrow was the best in Yongpo woodland,followed by fertilizer application in four points.Considering the construction cost and ecological benefits of different fertilization methods,cavernous fertilization was suggested for forest trees in Pinus kesiya var.langbianensis dominated mountainous areas,since the excavation area around trees is small, and it is conducive to soil and water conservation and soil erosion reduction.In addition,cavernous fertilization could save labor costs and is operable in production practice.
