Effect of stand Structure,Site Condition and Management Method on the Productivity of Bamboo Stands

  • Received Date: 1994-04-30
  • Successive surveys were made in bamboo(Phyllostachys pubescens)groves in Dagangshan region,Jiangxi Province from 1985 to 1991. Based on those data,the factors to affect yield such as stand structure,site condition and management method and their adjusting method were discussed.The results show that the most important factor was stand density which should be maintained in optimum situation,The optimum density of bamboo grove in the Jiangxia Forest Farm varied with the site condition and has been given as follows:4 950~5 550(1):4350~4800(2)、3 450~4 200(3)、2 400~3 300(4)、1 800~2 250(5) stems/hm2 respectively,Main site factors affecting productivity are soil and humus thickness,soil tightness and P content of soil.Fertilization can bring up a good output and high economic benefit,the increment in yield is 20%~100% and the increment is 22%~81% with the changes of the site conditions,so it should be used in suitable areas.

Abstract: Successive surveys were made in bamboo(Phyllostachys pubescens)groves in Dagangshan region,Jiangxi Province from 1985 to 1991. Based on those data,the factors to affect yield such as stand structure,site condition and management method and their adjusting method were discussed.The results show that the most important factor was stand density which should be maintained in optimum situation,The optimum density of bamboo grove in the Jiangxia Forest Farm varied with the site condition and has been given as follows:4 950~5 550(1):4350~4800(2)、3 450~4 200(3)、2 400~3 300(4)、1 800~2 250(5) stems/hm2 respectively,Main site factors affecting productivity are soil and humus thickness,soil tightness and P content of soil.Fertilization can bring up a good output and high economic benefit,the increment in yield is 20%~100% and the increment is 22%~81% with the changes of the site conditions,so it should be used in suitable areas.
