摘要
从广东、湖北、赣南等地引进的青皮竹、梁山慈竹、坭竹、黄竹在我市引种繁殖及栽植获得成功 ,通过无性繁殖育苗试验 ,结果表明 :采用母竹带蔸埋秆育苗和竹苗分株育苗 ,青皮竹、坭竹育苗成活率高达 90 %以上 ,当年平均每蔸发新竹 5～ 6株 ,新竹平均地径 1.0 4～ 1.4cm;黄竹、梁山慈竹采用竹苗分株育苗成活率可达 70 %以上 ,新竹平均地径 0 .9～ 1.4cm。造林 4～ 5 a以后 ,4种丛生竹梁山慈竹、青皮竹、黄竹、坭竹每年每 hm2 可产竹材分别为 1.47万 kg、1.7万 kg、2 .5 5万 kg、5 .4万
B.textilis,D.farinosns,B.gibba,B.rigida have been introduced successfully in Yichun City from Guangdong,Hubei,and the south of Jiangxi.The result of tests on asexual reproduction showed as follow:Adopted mother plants with root buring culms and young plants divided,the survival rate of B.textilis and B.gibba's seedlings was more than 90% and each plants could form avevagelly 5～6 news plants whose average ground diameter was 1.04～1.4m in this year.Adopted young plants divided,the survival rate of B.rigida and D.forinosns's seedlings was more than 70% and the new plants′ average ground diameter was 0.9～1.4cm.Four or five years after afforestation,D.farinosns,B. textilis,B.rigida,B.gibba, could produce respectively 14700kg·(a·hm 2) -1 ,17775kg·(a·hm 2) -1 ,25500kg·(a·hm 2) -1 ,54000kg·(a·hm 2) -1 .
