摘要(Abstract)：

为了解施肥对柳杉人工林幼龄林和中龄林生长量影响,2014年起在沐川县杨村乡对柳杉幼龄林和中龄林开展了施肥试验。结果表明,施肥对柳杉幼龄林生长有显著的促进作用,树高、地径生长量是不施肥的1.5倍以上,施肥对柳杉中龄林生长效果不明显,树高、胸径生长量与不施肥差异不显著。对3a生以内的幼龄林建议通过"林经间种",实施间接施肥,经济效益较为划算,对柳杉中龄林以上的林分,可采用抚育间伐等营林措施,提高生长量。
In order to understand the influence of fertilization on the growth of artificial Cryptomeria fortuna forests,fertilization tests were conducted on growth of young and middle-aged artificial forest of C. fortune in Yangcun Township,Muchuan County. The results showed that fertilization could significantly promote the growth of young-aged artificial forest. The height and diameter under fertilization were all more than 1. 5 times as compared with no fertilization. Fertilization had not significant influence on the growth of middle-aged artificial forest. There were not significant differences of height and diameter at breast height between fertilization and no fertilization. It was advised to promote economic benefits through"Forest intercropping"(cultivated cash crops among the trees) and indirect fertilization. In middle-aged forest stands,silvicultural measure like nurture and intermediate cuttings could improve the amount of growth.
