热带薪材林经营技术的研究

Study on Techniques for Management of Tropical Fuelwoods

根据多年对热带薪材林经营管理及林分采伐更新等的研究，总结了一整套经营技术，包括抹芽定株（保留２～３株／桩萌条）、追肥（复合肥３００ｇ／株）、采收更新的轮伐期（一般４ａ左右，超短轮伐期１．５～２ａ，桉树类与相思类树种的混交林约３年采收相思类树种）、采伐方式（短轮伐期薪材林皆伐、乔薪结合择伐或间伐）、采伐季节（避开雨季，最好时期为冬季，其次为夏季）、伐桩高度（桉树类约１０ｃｍ、相思类约６０ｃｍ高）以及其它与更新相关的林龄、桩径、树种等技术问题。

The management, harvesting and regeneration etc. of tropical fuelwoods are discussed based on our research data and some references. It concludes a set of technique for their management which contains thining of coppice shoots (left 2～3 shoots per stump), fertilizer supplement (300 g composite fertilizers per shoot), rotation age (generally about 4 years, 1.5～2 years for super short rotation age, about 3 years for harvesting Acacia in mixed forest), logging system (such as clear cutting and selective cutting), logging season (no logging in rainy season, winter the best and summer the better), stump height (about 10 cm for Eucalyptus, 60 cm for Acacia), and other technological problems such as forest age, stump diameter and tree species etc. which are closely related to their regeneration.
