摘　　要：为探究不同肥料对杉木幼林生长的影响,以2年生杉木幼林为研究对象,选用硝基复合肥、洋丰复合肥、东北丰复合肥、鄂中复合肥4种肥料,研究了不同肥料在施肥8个月后对杉木幼林株高、地径的影响,测算了不同施肥处理杉木幼林株高及地径增长量。结果表明:在广西来宾市金秀瑶族自治县杉木幼林种植中,相同施入量的不同肥料其促生长作用各不相同,在施入100 g/株鄂中复合肥时,杉木幼林株高及地径生长量最大,株高同比增幅达到了167.14%、地径同比增幅达到了218.68%,是最适宜当地的杉木幼林肥料。In order to explore the effect of different fertilizers on the growth of young Chinese fir plantation,taking the 2-year-old young Chinese fir plantation as the research object,four fertilizers,nitro compound fertilizer,Yangfeng compound fertilizer,Dongbeifeng compound fertilizer and Ezhong compound fertilizer,were selected to study the effect of different fertilizers on the plant height and ground diameter of young Chinese fir plantation after 8 months of fertilization,and the growth of plant height and ground diameter of young Chinese fir plantation under different fertilizer treatments was calculated.The results showed that in the planting of young Chinese fir plantation in Jinxiu Yao Autonomous County,Laibin City,Guangxi,the growth promotion effect of different fertilizers with the same application amount was different.When 100 g/plant Ezhong compound fertilizer was applied,the growth of plant height and ground diameter of young Chinese fir plantation was the largest,with a year-on-year increase of 167.14%in plant height and 218.68%in ground diameter,which was the most suitable fertilizer for local young Chinese fir plantation.
