Abstract

The invention discloses a caragana microphylla forest cutting rejuvenation method and relates to a culture technology of caragana microphylla. The invention solves the problem of easy generation of growth recession due to the increase of ages of the caragana microphylla forest. The caragana microphylla forest cutting rejuvenation method comprises the following steps of: dividing the caragana microphylla forest into cutting regions and retaining regions which are staggered and have the area ratio of 1:1 in the soil freezing period at the end of winter and the beginning of spring, wherein the area of each region is 2-5km<2>; and cutting off the whole clump once by using a sharp tool and cutting once every 3-5 years at the distance between a cutting opening and the ground of -3-3cm. The method disclosed by the invention has simple operation step, is easy for popularization and can effectively promote root growth to ensure that caragana microphylla growth vigour is good, eliminate plant diseases and insect pests, improve the blossoming and fruiting rate and generate larger economic benefits and ecological benefits.

Description

technical field [0001] The present invention relates to the cultivation technique of Caragana, in particular to a method for rejuvenating a Caragana grove. Background technique [0002] Caragana belongs to the family Caragana genus, a shrub. It is a large deciduous shrub plant of the family Caragana genus Fabaceae. The root system is extremely developed, and the main root penetrates deep into the soil. The plant height is 40-70 cm, and the maximum can reach about 2 meters. It is suitable for growing on sunny and semi-sunny slopes at an altitude of 900-1300 meters. Drought-resistant, cold-resistant, and high-temperature-resistant, it is an xerophytic shrub in arid grasslands and desert grasslands. At present, caragana is one of the important tree species for soil and water conservation and sand-fixing afforestation in Northwest China, North China, and Northeast China. It is an excellent plant for sand-fixing and greening barren hills, and is a good forage. Roots, flowers, a...
