摘要
为优化茶秆竹林抚育模式,探明抚育后的新竹生长总体影响与动态变化规律,研究在福建明溪天然茶秆竹林进行抚育模式(常规全面锄草模式、浅翻模式、浅翻施肥模式)试验,就其抚育后1-3年度新竹生长、总体生长情况进行分析,并采用主成分分析法进行综合评价。研究结果表明抚育模式显著影响着新竹数量、胸径、竹高、单株秆鲜重和秆产量等5个新竹生长性状,不同抚育模式的年度间新竹数量、胸径、竹高、单株秆鲜重与秆产量等5个新竹生长性状的促进作用大小、呈现显著影响的时间明显不同,综合评价结果表明浅翻施肥模式最佳。3种抚育模式年度间新竹生长情况均越来越好、呈现随抚育后时间推移而逐渐增加的变化。
In order to optimize the tending pattern of Pseudosasa amabilis forest,explore the general influence and growth dynamics of the new bamboo shoots after tending,a test of various tending pattern （conventional weeding mode,shallow ploughing mode,shallow ploughing and fertilizing mode） for the natural P.Amabilis forests was conducted in Mingxi County,Fujian,China to analyze the growth of 1-3 years old new bamboo shoots after tending,the 3 tending patterns were evaluated comprehensively by using the principal component analysis method.The results showed that the tending patterns significantly affected 5 indices,i.e.the number,DBH,height,individual stem fresh weight and stem yield of new bamboo shoots.The responding magnitude and time varied with patterns.In general,the shallow ploughing and fertilizing mode promoted the most the growth of new bamboo shoots.The annual growth of new bamboo shoots under all tending patterns,gradually increased.
