Eucalyptus compound cultivating method combining long and short period operation

Abstract

The invention discloses a eucalyptus compound cultivating method combining long and short period operation. The method comprises the steps that eucalyptus seeds, an area and forest land which are suitable for long and short period operation are selected, a suitable long period is determined according to the eucalyptus seeds, and in the process of long-period operation, 2-3 short-period operationsare conducted. Compound cultivating combining the long and short period operation is adopted for eucalyptus, the biological characteristics of the eucalyptus under different operation goals are exerted, and ecological conditions of light energy, thermal energy, space and the like of the forest land are fully utilized; in the compound operation process, the biological characteristic of regenerationof eucalyptus buds are fully utilized, cost input of increased production materials and labor of reforestation in the short-period operation process is reduced, the process adopts sustainable technologies such as ecological updating and the like, and the problem that the soil fertility of the operation land of the man-made eucalyptus forest is reduced is solved.

Description

technical field [0001] The present invention relates to the field of eucalyptus plantation cultivation and high-efficiency cultivation technique, specifically a kind of eucalyptus compound cultivation method combining long and short cycle management. Background technique [0002] Eucalyptus (Eucalyptus) is one of the most important fast-growing and high-yield tree species in southern my country. Its wood is widely used in pulp and papermaking, veneer rotary cutting and solid wood utilization. Since the introduction of Eucalyptus, it has developed rapidly in my country. By 2013 It has exceeded 3.5×10 6 hm 2 , with an annual output of 2.0×10 7 m 3 Timber has made an important contribution to my country's timber production. Due to the lack of relevant cultivation models and industrial guidance, blindly expanding the cultivation area, single tree species, simple structure, short-cycle operation and high-intensity predatory management, forestry productivity is low, which event...

AI Technical Summary

Problems solved by technology

Due to the lack of relevant cultivation models and industrial guidance, blindly expanding the cultivation area, single tree species, simple structure, short-cycle operation, high-intensity predatory management, and low forestry productivity, ultimately lead to low stand quality, low benefit, and forest land fertility decline. question

In addition, the material of eucalyptus wood is not good, and it is easy to warp and deform, so it is not suitable for structural materials, high-grade flooring and furniture materials, and its economic value is not high, so the scope of use is limited
