皆伐对细叶龙竹林分生长的影响研究
|
摘要
研究了不同皆伐方式、不同皆伐季节、不同伐桩高度、不同施肥方法以及不同松土深度对细叶龙竹林生长的影响。结果显示:小面积皆伐有利于机械化采伐作业,可降低劳动成本,提高劳动生产率,在生产上宜选择带状皆伐方式,带宽以8~12 m为佳;皆伐季节宜在冬季进行;伐桩高度以保留5~10 cm为宜;皆伐后进行伐桩施肥效果好于土壤施肥,以施复合肥为好;竹林伐后进行垦覆有利于竹林生长,松土深度应在20 cm以上。
The effects of clear-cutting methods,seasons for clear-cutting,height of stumps,fertilization ways and scarification depth on the growth of Dendrocalamus membranaceus cv. grandis forest were studied. The results showed that the small-area clear-cutting is beneficial to the mechanic logging operation,which could lower the labor costs and improve the productivity. The belt-shaped clear-cutting with 8-12 m in width is the optimal in production. Winter is the best season for clear-cutting. The height of stumps is better kept at 5-10 cm. The fertilization after clear-cutting could achieve better effects than soil fertilization,and compound fertilizers have better effect if applied. Plough and planting after the clear-cutting contribute to the bamboo forest growth,and the scarification depth is supposed to be more than 20 cm.
