摘　　要：以浙江省安吉县毛竹现代科技园区毛竹林为试验林,研究分析了长期测土推荐施肥的林地土壤养分、毛竹胸径及竹林产量。结果表明:长期测土推荐施肥的毛竹林,土壤养分含量能够保持在较高水平上,满足毛竹生长对土壤营养元素的需求;竹林新竹胸径整齐度较高,胸径大小稳定;竹林大年产量虽然有波动,但总体上呈连续增长的趋势;毛竹林测土推荐施肥明显减少了化肥施用量,对于节能减排、减轻面源污染等具有重要意义。Taking the moso bamboo forest in the Modern Science and Technology Park of Moso Bamboo in Anji County,Zhejiang Province,as an experimental forest,this paper analyzes the soil nutrients,bamboo's diameter at breast height(DBH),and yields of bamboo forest under long-term soil testing and recommended fertilization.The results show that the soil nutrients in bamboo forests under long-term soil testing and recommended fertilization can be maintained at a high level,which can meet bamboo's requirements of soil nutrient for the growth.The DBH of new bamboo culms in bamboo forests is of relatively high uniformity and have the stable size.Although the annual yield of bamboo forests generally presents a trend of continuous growth though with some fluctuations.Soil testing and recommended fertilization adopted in moso bamboo forests obviously reduces the amount of chemical fertilizers applied,which is of great significance in energy saving,emission reduction,and reduction of surface source pollution.
