The influence of cultivation measures, such as adjustment of bamboo strand structure, sun bathing of thebamboo shots and top-p runing on shoot, on culm morphologywere studied. The resultswere summarized as follows:The individual numbers per clump was negative correlated with malformation rate of culm, the op timal individualnumbers per clump was 4 - 5. From high malformation rate of new bamboo with different shooting period to low mal2formation rate, there appeared in turn earlier shooting, middle shooting and latter shooting. Some measures such asremoval of weak and small shoot and normal culm shoot increased malformation numbers, malformation rate andground diameter of new bamboo by 39. 2% , 118. 3% and 151. 9% respectively. Sun bathing of the bamboo shotsincreased the number of shoot, bamboo emerging, malformation and malformation rate by 17. 6% , 35. 4% , 79. 8% ,33. 0% respectively. Top2p runing on time was negative correlated with the number of shoot, bamboo emerging andmalformation rate, and the op timal height of top2p runing is 10 - 15 cm.
