Abandoned ginseng land soil improvement method

Abstract

The invention relates to the technical field of soil disinfection and improvement, in particular to an abandoned ginseng land soil improvement method. The technical scheme includes that the abandoned ginseng land soil improvement method includes the steps: sequentially disinfecting and restoring soil to be disinfected; performing plant restoration for the soil to be disinfected. Soil disinfection includes physical soil disinfection and chemical soil disinfection. The invention further provides a special device for physical soil disinfection and chemical soil disinfection. Compared with the prior art, the abandoned ginseng land soil improvement method has the advantages that abandoned ginseng land soil is improved by transforming and comprehensively using abandoned ginseng land, soil productivity is restored, and the abandoned ginseng land is reused by successive cropping. A soil environment more beneficial to ginseng growth is created, forest resources and the standing stock of ginseng under forest are increased, special machinery is used for operations such as disinfection, manpower cost is reduced, and working efficiency is improved.

Description

Technical field [0001] The present invention involves soil disinfection and improvement technology, especially a method of soil improvement in the land of abandoned people. Background technique [0002] Ginseng is a traditional valuable Chinese medicinal material in my country. It belongs to the five -Jiake perennial plant -based herbal plants. It has the effects of replenishing vitality, soothing and puzzle, replenishing the five internal organs, and delaying aging.China is a large country in the world. The cultivation area and output are the first in the world.Ginseng planting is the pillar industry of Jilin Province. At present, the method of ginseng cultivation in most places is mainly to cut forest planting ginseng. Because the soil is mostly forest soil, the soil is fertile, and the nutrients are sufficient.Therefore, a large amount of nutrients in the soil within a growth cycle of about 4-6 years; the fundamental changes in the soil in the 4-6 years of the growth cycle of ...

Problems solved by technology

Ginseng planting is a pillar industry in Jilin Province. At present, the main method of ginseng cultivation in most places is to plant ginseng in forests. Since the soil is mostly forest soil, the soil is fertile and has sufficient nutrients, so the yield of ginseng produced is high and the quality is good; but ginseng is a perennial plant Therefore, a large amount of nutrients in the soil are absorbed in a growth cycle of about 4-6 years; the fundamental changes in the microbial flora in the soil during the 4-6 year growth cycle are mainly due to the increase of pathogenic bacteria; The secretion of various substances and the substances secreted by ginseng against external adverse factors during the growth process accumulate in the soil, the toxins secreted by microorganisms and plants in the soil increase, and the planting of ginseng causes the destruction of large areas of deep forest. Since ginseng is a perennial plant, avoid The soil is extremely strong, and continuous cropping is not possible, that is, the soil after planting a crop of ginseng cannot be planted with ginseng again in a few years or even decades, and ginseng cannot be replanted again. The country has caused the destruction of deep forest resources.

Therefore, the ginseng planting industry is facing a serious crisis of lack of ginseng land, and the sustainable development of ginseng has been seriously challenged
