玉溪市薪炭林树种选择和营造技术

The silvicultural technique and species selection for the fuelwood plantation in yuxi city

  • 摘要: 玉溪薪炭林的试验结果表明,在玉溪地区营造薪炭林,可以推广的树种有蓝桉、直干桉、圣诞树、黑荆、川滇桤木5个树种,这些树种生长快,产薪量高。在玉溪地区营造薪炭林,以水平带状整地较好,规格宽60cm,深50cm,带间距200cm;造林密度以2m×1m的株行距较为合理;造林时间在雨季开始后7月中、下旬进行;营养袋育苗,造林成活率可达95%以上。该研究为玉溪地区营造薪炭林提供了科学依据,对大力发展薪炭林,保护森林资源,解决工农业生产和群众生活能源短缺具有指导意义。

     

    Abstract: The experiments on fuelwood were carried out in Yuxi City,The data in-dicated that the suitable tree species for fuelwood plantation in Yuxi district were Euca-lyptus globulus,E.maideni,Acacia mearnsii,Aluns nepolensis and A cacia dealbata.These species were characterized by fast growth and high production of fuelwood.Thesite preparation in level belts with 60 cm in width,50 cm in depth and 200 cm ininterval,and planting density with spacing of 2 m×1 m were proposed for fuelwoodplantation in Yuxi district.The optimal season for planting was the period between middle and late July when the raining season began.The survival ratio of the plantationplanted with nutritional bag was over 95%.Application of fertilizer (20 g/tree) in the 3succeeding years after planting could increase biomass and accelerate closure of the plan-tation.The annual biomass of fuelwood was about 16.88~34.04 t/hm2 (air dry weight)in the flrst 1.25 years of the young plantation for the selected species.The stump heightalso had some influences on the sprouting and biomass of the selected tree species.Theproposed stump height were 30 cm for Eucalyptus,> 30 cm for Alnus nepalensis,>50 cm for A cacia mearnsii and no limit for A cacia dealbata.The result provided the re-liable information for the extension and development of fuelwood plantation,the reser-vation of forest resource and the resolution of energy shortage in agriculture and indus- try production as well as in people's fuelwood in Yuxi district.
