摘　　要：根据N、P、K三要素不同水平设 12种不同的养分比,对江西宜春幼龄油茶进行配方施肥试验。试验采用随机区组设计,并用LSD法进行多重比较。结果表明,配方施肥对幼龄油茶生长有促进作用,N、P一定时,增加K肥有利于树高、冠幅和叶面积的增大;N、K一定时,增加P肥有利于幼龄油茶叶面积的增大;P、K一定时,N的施用量为 0. 50kg·株 -1·a-1,不利于幼龄油茶的生长。所设 11个施肥处理中,以N2P1K1 (2∶1∶1. 3)和N1P1K2 (1∶1∶2. 6)两处理表现较优,对树高、冠幅、叶面积、叶绿素值的影响均达显著水平。According to different levels, 12 kinds of different nutrients ratio of three main factors— N, P, K on young Camellia oleifera was studied in Yichun of Jiangxi Province. The experimentation was designed in random block design and the LSD was used to put up multiple comparison. The results show that: ratable fertilizer can stimulate the growth of young C. oleifera. When the amounts and the proportions of N,P are fixed, adding K can in favor of the height, crown and leaf area. When N,K are constant, adding P can aggrandize leaf area. When P,K are invariable, fertilize N in term of N_3 can not stimulate the growth of the plant. Among these eleven fertilized treatments, N_2P_1K_1(2∶1∶1.3) and N_1P_1K_2(1∶1∶2.6)are more effective than the others,the effects on the height, crown, leaf area and chlorophyll are significant.
