To examine the characteristics of the Moso bamboo growth process, we selected 140 young plants in Qingshan of Zhejiang province to measure the height and observe the growth trend under 2 management models: intensive and extensive. The whole growth process of bamboo shoots was continuously monitored for 57 days. The trend was quantified by height every day. Growth characteristics of young bamboo were analyzed by non-parametric hypothesis test and correlation analysis. Growth rate showed an obvious stage change characteristic, and curves between time and growth rate tended to be a bell shaped, with maximal peak at the right side. The growth rate of young bamboo was slow during the first 15 days and rapidly increased from days 15 to 45, then tended to decrease after 45 days. The growth rate differed in different stages, but the degree of growth was similar between intensive and extensive management. Growth rate variance was small during the first 20 days and then severely fluctuated after 20 days. Growth rate did not differ between intensive and extensive management during the first 10 and last 15 days. The difference in growth rate between intensive and extensive management fluctuated from days 11 to 28. Growth rate significantly differed between intensive and extensive management from days 29 to 40. The findings may guide M. bamboo management and forest research in theory.
