摘　　要：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.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 latt...
