采用五点法对宜宾市分布较多的4种竹资源,硬头黄竹、撑绿竹、慈竹和绵竹不同生育期的鲜重、总鲜重和经济效益分析,结果表明:1)不同竹种总鲜重平均大小为慈竹>撑绿竹>绵竹>硬头黄竹,不同生育期鲜重平均大小为1a生竹>2a生竹>多年生竹;2)不同生育期竹鲜重与总鲜重相关程度较高,绵竹总鲜重与2a生竹鲜重极显著相关,相关系数为0.943;3)不同竹种经济效益表现为慈竹>绵竹≈硬头黄竹>撑绿竹,撑绿竹1a生阶段经济效益比例高达44.58%,多年生阶段经济效益所占比例最小为22.78%。
The five-point method was used to analyze the fresh weight, total fresh weight and economic benefit of four bamboo resources with more distribution in Yibin, Huangzhu, Stipulchus, Muxian and Mianzhu. The results showed that: 1) The average fresh weight of bamboo species was Phyllostachys praeparatus> Stipulation of bamboo> Mianzhu> Stipa massoniana, and the average fresh weight of different growth stages was 1a-1 bamboo> 2a-bamboo> perennial bamboo; 2) The correlation coefficient was 0.943; 3) The economic benefits of different bamboo species showed that Phyllostachys pubescens 绵 硬 hard yellow bamboo> Phyllostachys praecox, The proportion of the economic benefits of green bamboo during the first phase of life is as high as 44.58% and the lowest proportion of economic benefits of the perennial phase is 22.78%.
