摘要
本文采取产区调查及定位观察相结合的方法,对高节竹(PhyllostachysprominensW.Y.Xiong)笋用林的竹林结构和抚育管理措施进行了调查研究,并运用对比、归纳等分析方法,得出初步结果:1.竹林的年龄结构以1:1:1:1(1年生:2年生:3年生:4年生),立竹株数每公顷5250-6750株,平均胸径5.0—6.0cm,SN0.85—1.10,LAI7.0—8.0为宜。2.施肥以农家有机肥为主,施化肥N.P.K的比例以5:1:3为宜,提倡多投工,多施肥。3.高节竹的平均公顷产值25274.23元,最高可达36978.69元,平均劳动盈利率87.9%。
Bamboo stand structures and tending management measures of ph. prominens stand were studied by means of on-the-spot investigation and positioning observation. In addition,through such analysis methods as comparison、induction and so on, some preliminary conclusions have been drawn up 1. The optimal age structure of bamboo stand is 1: 1: 1: 1 for each 1 -,2-,3-and 4 year old bamboo, the density is 5250-6750 plants per ha.,with a mean DBH of 5-6 cm,the SN of 0. 85-1. 10,and the LAI of 7. 0-8. 0.2. It is recommended to mainly apply manure. If unorganic fertilizer,the ratio of N,P and K is 5: 1: 3,with more labor inputs and fertilizer application advocated.3. The average output value of Ph. prominens stand is RMB 25274.23 yuan per ha.,even at highest,RMB 36978. 69 yuan per ha.,with a mean labor profit rate of 87. 9%.
