通过5年来对云南主要散生竹(斑竹、水竹、灰金竹、桂竹)无性繁殖育苗技术的系统研究,总结出各竹种经济实用的育苗方法。试验结果表明:正确选择苗圃地及竹鞭,选用适当的植物生长调节剂处理竹鞭,适时育苗,采用塑料小拱棚覆盖苗床,两段式长鞭分株育苗,进行科学抚育管理,可使育苗成活率由传统育苗方法的10%~30%提高到80%~95%,竹苗质量明显改善。经推广应用,取得了良好的生态、经济和社会效益。现已培育竹苗3601万株,规模化造林68591hm2,节约投资9259万元,前期营造竹林已开始郁闭成林。
Through five years’ systematic research on asexual reproduction techniques of main scattered bamboo in Yunnan Province, this paper summarized the economical and practical breeding methods of bamboo species. The results showed that the correct selection of nursery and bamboo whip, the selection of the appropriate plant growth regulator bamboo whip, timely nursery, the use of plastic small shed covered seedbed, two-stage long whip ramets breeding, scientific management, can nursery Survival rate increased from 10% to 30% of traditional seedling raising method to 80% to 95%, and the quality of bamboo seedlings improved significantly. The promotion and application, has made a good ecological, economic and social benefits. Now 36,1000 bamboo seedlings have been nurtured, large-scale afforestation 685 91hm2, saving 92,590 yuan investment, early bamboo forest has begun to set up closed forest.
