摘要
在福建省福安市城阳乡占洋村、溪柄镇黄兰和白沙村绿竹低产林中采用随机方法设置试验小区,进行绿竹低产林改造的产量和经济效益分析.对试验结果采用LSD分析,结果表明,低产林改造对绿竹产笋量影响极显著,产量比CK提高了280.84%~289.85%,但对竹材产量影响不大.经济分析表明,低产林改造后的竹林每年比CK增加纯收入15 948.29~16 282.85元/hm2.
The experimental zones were designed by a random method for Dendroca lamopsis ＇s low-yield forest in Huanglan and Baisha village of Xibing Township and Zhanyang village of Chengyang township of Fu＇an city in Fujian province to analyze the yield and economic benefit of the transformation of Dendroca lamopsis＇ low-yield forest.The results analyzed by LSD showed that such a transformation had extremely influenced the yield of bamboo shoots,and the output had increased 280.84%~289.85% than CK,but there was little influence on bamboo timber yield.Besides,Economic analysis showed that the annual net income from the transformed forest increased more 15948.29~16282.85 yuan/hm2 than CK.
