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%。
In this paper, bamboo production and management practices of Phyllostachys prominensW.Y.Xiong bamboo shoots were investigated by field survey and location observation. By using comparative analysis, inductive analysis and other methods, Preliminary results: 1. The age structure of bamboo forest is 1: 1: 1: 1 (1-year-old: 2-year-old: 3-year-old: 4-year-old). There are 5250-6750 bamboo plants per hectare with average DBH 5.0-6.0cm, SN 0.85- 1.10, LAI7.0-8.0 is appropriate. 2. Fertilizers dominated by organic fertilizer, fertilizer N. P. The ratio of K to 5: 1: 3 is appropriate to promote multi-cast workers, more fertilizers. 3. High section bamboo average output value of 25,774.23 yuan hectares, up to 36,978.69 yuan, the average labor profitability 87.9%.
