Lin’an Forestry Bureau , Lin’an 311300 , China) Abstract :Soils and bamboo shoots getting from two kinds of intensive managements are analyzed in order to exploit the influence of intensive management on the bamboo shoot’s quality. The result shows that intensive management could improve the content of soil nutrition comparing with extensive management. And intensive management can increase the quantity of starch and free amino acids while decreasing total quantity of sugar , proteins and fats. The content of minerals such as S , Ca , Mg , Fe , Mn , Cu , Zn , Si and Na in bamboo shoot is reduced but the mineral elements as P and K go up. Key words : Bamboo shoo
