摘　　要：于2020—2021年,在福建省顺昌埔上国有林场连续2 a开展毛红椿和杉木混交幼林施肥试验,探讨不同肥料类型及施肥量等对毛红椿和杉木混交幼林生长量的影响。结果表明:施肥处理的林分地径、树高、当年抽高,1年生时分别比对照增加26.18%、7.25%、62.5%,2年生时分别比对照增加12.83%、19.62%、28.09%。同一施肥类型不同施肥量对毛红椿和杉木混交幼林生长表现的影响,总体上随着施肥用量的增加,混交幼林的地径、树高、当年抽高均呈现增加趋势。施用不同肥料类型对毛红椿和杉木混交幼林生长影响排序为混合肥>复合肥>有机肥。方差分析表明,1年生时,地径在不同重复间和不同处理间的差异均达极显著水平,在重复和处理互作效应的差异达显著水平;树高在不同重复间的差异达极显著水平,而在不同处理间的差异不显著;当年抽高在重复间和处理间的差异均达极显著水平。2年生时,地径和当年抽高在不同处理间的差异均达显著水平;树高在不同处理间的差异均达极显著水平,而在不同重复间的差异均不显著。经过2 a的施肥试验表明,毛红椿和杉木混交幼林施肥方案以混合肥且施肥量150 g·株^(-1)为最好,对毛红椿和杉木混交幼林地径生长的影响最显著。The effects of different fertilizer types and amounts on the growth of young mixed forests of Toona ciliata and Cunninghamia lanceolata were investigated by fertilization experiments of Pushang State-owned F o rest Farm of Shunchang,Nanping in 2020 and 2021,the results were as followes:the ground diameter,tree height,and annual height of the fertilized stand were increased by 26.18%,7.25%and 62.5%compared to the control value respecti vely at the first year,and 12.83%,19.62%and 28.09%at the second year.As a whole,the ground diameter,tree height,and annual height of the young mixed forests showed an increasing trend with the increase of fertilizer amount.With regard to the effects of the different fertilization type,the effect of differen t fertilizer type on the growth of forests were mixed fertilizer>compound fertilizer>organic fertilizer.In the first year,the ground diameter show very signific ant differences among repetitions,treatments and interaction between repetition and treatment,tree height show very significant differences among repetitions and not differences among treatments,and annual height show very significant differences among repetitions and treatments.In the second year,the ground diamet er and annual heigh show significant differences among treatments,tree height show very significant differences among treatments and not differences among repe tition.And it was found that the growth performance of ground diameter was mostly impacted by fertilization after two years experiments,and the mixed fertilizer with a fertilization rate of 150g per plant was the best for young mixed fore sts of Toona ciliata and Cunninghamia lanceolata.
