A soil improvement method for abandoned ginseng fields and a soil disinfection device thereof

Abstract

The invention relates to the technical field of soil disinfection and improvement, in particular to a soil improvement method for abandoned ginseng fields. The technical solution of the present invention is realized in the following way: a soil improvement method for discarded ginseng field, comprising the steps of soil disinfection, soil remediation, and phytoremediation for the soil to be sterilized sequentially, and the soil disinfection includes soil physical disinfection and soil chemical disinfection method, the present invention also provides a technical scheme of a special device for soil physical disinfection and soil chemical disinfection. Compared with the prior art, the beneficial effect of the present invention lies in that the soil of the abandoned ginseng field is improved through comprehensive utilization through the transformation and comprehensive utilization of the abandoned ginseng field, the productivity of the soil is restored, and the purpose of repeated cropping and reuse of the abandoned ginseng field is achieved. Create a soil environment that is more conducive to the growth of ginseng, increase forest resources and the reserves of under-forest ginseng, use special machinery for disinfection and other operations, reduce labor costs, and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of soil disinfection and improvement, in particular to a soil improvement method for abandoned ginseng land and a soil disinfection device thereof. Background technique [0002] Ginseng is a traditional precious Chinese medicinal material in my country. It belongs to the perennial root herb of Araliaceae. China is a big country producing ginseng in the world, and its cultivation area and output both rank first in the world. 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 ginseng produced is high in yield and good in quality; 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 th...

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 ginseng produced is high in yield and good in quality; 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
