A kind of method for cultivating natural vaccinia forests

Abstract

The invention discloses a method for reforming and cultivating a natural vaccinia forest, which belongs to the field of transforming and cultivating a natural forest of wild blueberries. The technical problem to be solved by the present invention is the degradation of natural resources of wild vaccinia, the reduction of yield, the serious phenomenon of big and small years and the like. The invention scientifically selects the replanted forest land, rationally divides it, sets survey quadrats, and determines the implementation mode of recultivation according to indicators such as the cover degree of bilberry and the cover degree of associated shrubs. The main reforming operation methods include replanting, flat stubble, pruning, light-transparent cutting and thinning. According to the survey data, one or a combination of several operation methods should be used for operation. Auxiliary operation is the use of insects to assist pollination. Carry out continuous comprehensive management after the reform and training operation is implemented. The invention transforms and cultivates low-quality and low-efficiency vaccinia natural forests, generally within 3 to 5 years, the productivity of wild vaccinia forests can be significantly improved, the stand space structure is more reasonable and stable, and the comprehensive functions and benefits are remarkable enhanced.

Description

technical field [0001] The invention belongs to the field of transforming and cultivating wild blueberry natural forests, and in particular relates to a method for transforming and cultivating natural blueberry forests. Background technique [0002] my country is rich in wild blueberry resources, but only Vaccinium uliginosum L. is used for commercial harvesting, which is the wild blueberry in northern my country. It is mainly distributed in the Greater and Lesser Khingan Mountains and Changbai Mountains. species, one of the most valuable small berries in the north. In the Greater and Lesser Khingan Mountains forest areas, the vaccinia dusi has become one of the most distinctive pillars of the under-forest economic industry, and has played a decisive role in the local economic development. [0003] Vaccinium dusi is a small deciduous shrub of the Rhododendronaceae Vaccinium genus, with a height of 0.5-1 meters (the plant height of those born in high mountains is only 10-15 c...

Problems solved by technology

First of all, manual care is a passive measure, the contractor is not motivated, the operation is difficult, the rate of return is low, and it is difficult to maintain; the effect of artificial tending is better, but the labor cost is high, and the short-term rate of return is insufficient; the investment in active restoration is large, and the rate of return is low. The effect is not obvious when the forest formation rate is low
