母竹年龄对四方竹栽培成活率及成竹率的影响

摘要

Taking 1~4 -year -old Chimonobambusa quadrangularis (Fenzi) as test material ,this article contrasts the differences in afforestation survival rate ,shooting rate and grown bamboo rate between different ages of mother bamboos .The results show that :different ages of mother bamboo have significant effects on the above -mentioned three indexs;2 -year -old bamboo has the highest afforestation survival rate ,shooting rate and rate of grown bamboo ,which is respectively 91 .50% ,87 .40% ,82 .57% ;3 -year -old mother bamboo takes the second place ;the three indexs of 1 -year -old and 4 -year -old mother bamboo are lowest .Thus ,2~3 -year -old mother bamboos are the rational selection in building C .Quadrangularis (Fenzi) afforestation ,and 2 -year -old mother bamboo is the best option .%以1～4年生的四方竹母竹为试验材料，比较了各年龄母竹的种植成活率、出笋率和成竹率差异。结果表明：不同年龄母竹对四方竹的种植成活率、出笋率和成竹率均有显著影响，以2年生母竹的种植成活率、出笋率和成竹率最高，分别达到91．50％、87．40％、82．57％；3年生母竹略低；1年生和4年生母竹的种植成活率、出笋率和成竹率最低。因此，四方竹的造林选用2～3年生母竹为宜，其中以2年生母竹为最佳。
