[目的]研究施肥对不同坡位毛竹林的影响，以提高毛竹产量，增加农民收入。[方法]对福建省尤溪县西芹村不同施肥管理和不同坡位毛竹出笋量、新竹地径和枝下高进行研究。[结果]施肥管理和不施肥管理新竹枝下高和出笋量均为显著差异，施肥管理能有效提高竹林产量；不同坡位样地内的新竹枝下高和出笋量均为显著差异，而新竹地径差异性不显著，不同坡位上新竹枝下高、新竹地径、出笋量从大到小均依次为下坡位、中坡位、上坡位，下坡位竹林生产量最高。[结论]在毛竹低产林改造过程中，采用施肥管理，对毛竹林产量会产生显著的影响；在实践生产中，下坡位水肥条件较好，更有利于竹林出笋和竹材生产。%Objective] To research the effects of fertilization on Moso bamboo forest in different slope positions to enhance the yield of Moso bamboo,and to increase farmers′income.[ Method] We researched the bamboo ( Phyllostachys heterocycla) shoots quantity, ground diameter of new bamboo, and clear bole height in Xiqin Village, Youxi County, Fujian Province in different slope positions under different fertilization managements.[ Result] Fertilization management had significant differences with no fertilization management in bamboo shoots quantity and clear bole height.Fertilization management could effectively improve the output of bamboo.Clear bole height and bamboo shoots quantity in different slope positions showed significant differences; while ground diameter of new bamboo had no significant differences.Bamboo shoots quantity, ground diameter of new bamboo, and clear bole height from big to small were in the order of minus grade, mesoslope and upslope. Bamboo production in minus grade was the highest.[ Conclusion] During the renovation of low-yield bamboo forest, fertilization management is adopted, which has significant impacts on yield of bamboo forest.During practical production, minus grade has relatively good water and fertilizer condition, which is suitable for the shooting and production of bamboo forest.
