Study on the Relationship between Nutrition Dynamics and Yield of Phyllostachys pubescens

  • Received Date: 1994-12-31
  • The research was conducted in 1989~1993 in Longhu Forest Farm of Shaowu City, Fujian Province. The randomized blocks design included eleven treatments and three repetitions. The main results were as follows:(1)The nutrient content in the leaves,roots and soil changes with different season or year,which is closely related to the growth characteristics and yield of bamboo forest;(2)The content of N,P and K in the leaves and roots reduces with the increase of their age. There were similar nutrient contents in the leaves of the same age;(3)In the shooting stage,the order of importance of N,P, K in leaves and soils were PN,but in spring the soil hydrolysable N was closely related to the output Qf shoots and clums. This study provides some theoretical basis for nutrient diagnosis and reasonable fertilization.
