摘　　要：以长林系列3号、4号、23号、27号、40号和53号6个品种的芽苗砧嫁接苗进行高低施肥量试验,研究品种间对施肥量的表现。试验结果表明:品种因素对植株的根系生长具有显著的影响。施肥量也对根梢的同步生长具有一定的影响。随着增加施肥量情况下,长林53号无显著变化,长林3、长林4、长林40号中可以显著提高生长量;长林23、长林27号中高施肥量不利于植物的生长。The effect of fertilization on the growth of camellia oleifera grafting seedlings of six varieties,including Changlin 3,4,23,27,40,53 was studied.The results showed that there were differences in performance of the amount of fertilization in different varieties,and it did not necessarily promote plant growth in multiple fertilization;Besides affecting root growth,development and distribution,the impact of fertilization on the growth of root hair should not be ignored;there was different adaption ability in different species to fertilization.Changling 53 was of weak adaption ability to fertilization;enough fertilization improved the growth of Changlin 3,4,40;increased amount of fertilizer,was unfavourable to the growth of Changlin 23,27.
