所有的造林树种,均具有开花结实能力,主要是靠种子繁殖,这叫有性繁殖。要扩大种植面积,通常是用种子播种青苗造林。而竹类植物却不一样,开花结实罕见,其繁殖是靠营养体如:竹节、竹枝、竹鞭繁殖,这叫无性繁殖。而丛生竹地下茎为合轴型,粗而短,不能在地中作长距离的横走,扩大竹林面积,过去习惯上采用移母竹造林。用这种方法扩大造林面积,存在种源不足、成活率低、工效低、成本高的缺点。为了解决上述问题,广西林科所和有关单位进行了研 All afforestation species, are flowering and fruiting ability, mainly by seed breeding, called sexual reproduction. To expand the planting area, usually planting seedlings with afforestation. The bamboo plants are not the same, flowering sturdy rare, its breeding is nutrition body such as: bamboo, bamboo, whip breeding, called asexual reproduction. However, the underground stems of the clustered bamboo are co-axial, coarse and short, and can not make long-distance horizontal walks in the ground to expand the area of ​​bamboo forests. In this way to expand afforestation area, there is lack of provenance, low survival rate, low efficiency, high cost shortcomings. In order to solve the above problems, Guangxi Forestry Branch and relevant units conducted a research
