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

specific Embodiment approach 1

[0029] A method for cultivating natural vaccinia vaccinia forests, comprising the steps of:

[0030] Step a, carry out preparatory work: select the forest land for replanting, randomly set up survey quadrats, record the cover degree of Vaccinium cranberry and the cover degree of associated shrubs, and calculate the average value;

[0031] Step b, select one or more combinations of replanting, flat stubble, pruning, light-transparent cutting and thinning according to the cover degree of the Vaccinium cranberry layer calculated in step a; the replanting can be Use artificial seedlings or original plant clusters for uniform replanting and fixed-point replanting. After the slow seedling stage, replace the dead seedlings once, and manage the same year after planting; flat stubble can be used for uniform strip flat stubble and uneven block There are two operation modes of flat stubble;

[0032] Step c, using insects to assist pollination;

[0033] Step d, comprehensive management....

Abstract

The invention discloses a vaccinium uliginosum natural forest improvement and transformation method and belongs to the field of wild blueberry natural forest improvement and transformation, aiming tosolve the technical problems that natural resource of wild vaccinium uliginosum degrades, output of vaccinium uliginosum is reduced, situation of alternate bearing is severe and the like. According tothe method, improved and transformed forest land is selected scientifically and divided reasonably, survey quadrat is set, and improvement and transformation operating type is determined according toindex such as the coverage of vaccinium uliginosum and the coverage of associated shrubs. The main improvement and transformation operating types include after-replacement, stumping, pruning, releasing cutting and thinning; one or multiple of the operating types are selected according to survey data. Auxiliary operating type includes insect pollination. Comprehensive management is carried out after implementing of the improvement and transformation. The method can be used for improvement and culture of low-quality ineffective vaccinium uliginosum natural forest, improves productivity of the vaccinium uliginosum forest greatly after three to five years generally, makes stand spatial structure more reasonable and stable, and improve comprehensive function and benefit remarkably.

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...
