The influence of cultivation measures,such as adjustment of bamboo strand structure,sun bathing of the bamboo shots and top-pruning on shoot,on culm morphology were studied.The results were summarized as follows: The individual numbers per clump was negative correlated with malformation rate of culm,the optimal individual numbers per clump was 4-5.From high malformation rate of new bamboo with different shooting period to low malformation rate,there appeared in turn earlier shooting,middle shooting and latter shooting.Some measures such as removal of weak and small shoot and normal culm shoot increased malformation numbers,malformation rate and ground diameter of new bamboo by 39.2%,118.3% and 151.9% respectively.Sun bathing of the bamboo shots increased the number of shoot,bamboo emerging,malformation and malformation rate by 17.6%,35.4%,79.8%,33.0% respectively.Top-pruning on time was negative correlated with the number of shoot,bamboo emerging and malformation rate,and the optimal height of top-pruning is 10-15 cm. 展开更多

以引进竹种Guaduaamplexifolia为对象,进行了适生性和多种人工措施对幼林林分结构影响的研究,结果表明:该竹种适生于中亚热带与南亚热带气候过渡区,笋期长达7个月,笋芽萌发能力强;栽植后前2年丛新竹数、新竹地径变化显著,栽植后第3年始... 以引进竹种Guaduaamplexifolia为对象,进行了适生性和多种人工措施对幼林林分结构影响的研究,结果表明:该竹种适生于中亚热带与南亚热带气候过渡区,笋期长达7个月,笋芽萌发能力强;栽植后前2年丛新竹数、新竹地径变化显著,栽植后第3年始需进行人工去除弱小立竹和竹笋、科学适量挖取种苗等方法的竹丛结构调控,促进竹丛良好生长;可采用竹丛全年多次连续育苗法,显著提高优质种苗繁殖规模,其中以6月份移栽2~3株立竹带1~2株老竹的竹丛效果好。栽植后第3年始竹丛趋于散生状生长,根系发达,根径与立竹地径呈线性增长关系,根幅面宽,固土作用强。 展开更多
