摘要
通过对毛竹林连续5a的竹腔施肥试验,分析毛竹增产剂配方中各试验因素和水平之间对毛竹新竹数、新竹平均胸径、出笋数及成竹率的影响,并对竹林竹腔施肥前、后总体效果进行比较。结果表明试验期年均水平与试验前水平相比,新竹量、新竹平均胸径、年均出笋数、成竹率分别提高了62.8%1、6.9%6、9.0%和17.9%。试验区与对照区相比,新竹量、新竹平均胸径、笋产量、成竹率分别提高了75.0%1、5.2%、79.7%、35.2%,年均增加收益115.9%。
After a 5-year experiment of cavity-injecting fertilization on PhyUostcehys pubescens, the influence on new bamboo numbers, average D. B. H, bamboo shoot numbers and O＇owing-bamboo rate between the factors and levels in the different treatments has been analyzed. The results showed that after fertilization, the new bamboo numbers, average D. H. B, bamboo shoot numbers and growing-bamboo rate has increased by 62.8 %, 16.9 %, 69.0% and 17.9 % respectively, and the differences between experimental area and check of these index above were 75.0%, 15.2% ,79.7% ,35.2% respectively, the average increment of economic benefit was 115.9% per year.
