Brush stumping method for caragana korshinskii artificial forest

Abstract

The invention discloses a brush stumping method for a caragana korshinskii artificial forest. The method mainly comprises the content of brush stumping forest stand selection of the caragana korshinskii artificial forest, brush stumping time, brush stumping height, brush stumping cycles, brush stumping modes, brush stumping methods, management after brush stumping and the like. all caragana korshinskii needs to be updated through brush stumping, when the caragana korshinskii artificial forest grows for 10 years or so, the degree of lignification is increased, growth is weak, branches are aged, and at the period, brush stumping needs to be carried out for the first time; the brush stumping cycle is determined according to site conditions and growth conditions of the caragana korshinskii, the brush stumping cycle is 5-6 years in terms of the caragana korshinskii artificial forest with poor site conditions and weak growth vigor, and the brush stumping cycle is 8-9 years in terms of the caragana korshinskii artificial forest with good site conditions and strong growth vigor; the brush modes include a block-shaped work method and a spaced belt-shaped work method; the brush stumping methods include artificial brush stumping and mechanical brush stumping; due to the stimulation function of brush stumping, new trunks or shrubs sprout, tree vigor is improved after brush stumping, growth is vigorous, diseases and pests are reduced, and forest stand quality is greatly improved.

Description

technical field [0001] The invention relates to a stubble-leveling method for Caragana plantation, belonging to the field of agricultural plant planting. Background technique [0002] Caragana intermedia is a large shrub of the Leguminosae genus Caragana Fabr, mainly distributed in Jilin, Liaoning, Hebei, Shandong, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu, Qinghai and Xinjiang provinces ( area), is one of the important tree species for soil and water conservation and sand-fixing afforestation in Northwest China, North China, and Northeast West. It is suitable for growing on sunny and semi-sunny slopes at an altitude of 900-1300 m. Caragana has strong vitality, wide adaptability, drought resistance, cold resistance, and high temperature resistance. It is an xerophytic shrub in arid grassland and desert grassland. It can grow normally in mobile sandy land and inter-dune lowland with extremely poor fertility and sand layer moisture content of 2% to 3%, as well as on fi...

AI Technical Summary

Problems solved by technology

After 8 to 10 years of caragana growth, the branches become thicker, the degree of lignification is significantly enhanced, the growth declines year by year, the regeneration performance is weakened, the seed setting rate and stress resistance are greatly reduced, and it is extremely vulnerable to diseases and insect pests, and gradually declines and even dies. and social benefits are greatly reduced, leading to land desertification and deterioration of ecological benefits
