摘要
采用2因子2次回归正交试验设计,探究单位面积年龄比例和经营密度对苦竹出笋情况和产量的影响.根据出笋情况,确定当地出笋周期,并选定最佳方案,为今后苦竹林地的经营管理提供依据.结果表明:发笋趋势为先增后减,当地发笋盛期为4月16日至4月23日,经营密度为12500株·hm-2、年龄结构为1∶1时,发笋总数最多.
Setting different ratio of age and management density in unit area,using the orthogonal experimental design of two regressions of two factors,effects of stand structure on the shoot yield of Pleioblastus amarus were investigated.According to the shooting condition,the local bamboo shoots producing period of Pleioblastus amarus was determined,and the optimal experimental design was adopted,to provide the theoretical basis for the management of Pleioblastus amarus.The results showed as follows.Bamboo shoots trend of producing was increasing followed by decreasing.The peak period of local bamboo shoots producing was from April 16 to April 23.When the optimal experimental design was the management density of 12500 · hm-2 and the age structure was 1∶1,the local Pleioblastus amarus＇s shoot yield was the highest.
