毛竹林不同层次丰产模式试验初报

A PRELIMINARY REPORT ON EXPERIMENT OF DIFFERENT MANAGEMENT MODELS OF HIGH YIELD PHYLLOSTACHYS PUBESCENS FORESTS

  • 摘要: 1990~1993年对福建省三明市梅列区国营台江林业采育场的187hm2毛竹林进行了不同层次的丰产模式试验。设置 A,B,C 三个不同层次的抚育措施,平均每公顷增新竹分别为505株、485株、650株,胸径增长率分别为4.7%,7.0%,5.5%。三年投入资金为83560元,产值为29.8万元,投入与产出比为1:3.5。具有较高的经济效益和社会、生态效益。

     

    Abstract: Different management models of high yield forests were experimented in 187 hm2.bamboo forests on National Forest Nursury Farm of Taijiang, Meilie, Sanming City, Fujian Province from 1990 to 1993.Among the given three models, namely Models A, B and C, the numbers of new bamboo plants were 34, 32 and 43 and the increasing rate of width diameter were 4.7%, 7.0% and 5.5%, respectively.In three years the investment was RM8 83, 560 yuan while the value of output was RMB 298, 000 yuan.The ration of input to output is one to three point five.The experiment showed the high economic, social and ecological efficiency.
