施肥对油茶幼林营养生长的影响

摘要

对长林系列油茶无性系分别施有机肥、复合肥、尿素,环状沟施或散施处理,观测各无性系树高、冠幅、地径、新梢长度的生长量指标并进行分析,结果表明:不同追肥处理对油茶幼林树高、冠幅等营养生长性状有显著影响:3种肥料对油茶幼林营养生长的促进作用有机肥＞复合肥＞尿素;不同施肥对油茶幼林营养生长的促进作用冠幅＞树高＞新梢长＞地径;沟施效果好于散施.%Experiments were conducted on application of different fertilizers to young clones of Camellia oleifera in Qingtian,Zhejiang province.The result demonstrated that fertilization had evident effect on vegetative growth of Camellia,like height,crown diameter,ground diameter and new shoot length.Analysis indicated that the effect of fertilizers were ordered by organic manure ＞ compound fertilizer ＞ urea.
