Soil conditioner for old ginseng fields

Abstract

The invention provides a soil conditioner for old ginseng fields, comprising 20-30 wt% of composite amino acid solution, 45-52 wt% of plant ash, 18-32 wt% of fertilizer, and 1-3 wt% of antibacterial agent. The soil conditioner is rich in ginseng rooting regulator, nutrition balance agent, sustained release agent, disease-resistant bioactivator, antibacterial agent, antidote, and the like, is a multi-functional soil regulating agent for old ginseng fields, can carry out all-around soil conditioning and repairing on old ginseng fields, promote breeding of beneficial microbes, promote the physicochemical indexes of old ginseng fields to be benign, so as to promote ginseng roots to develop and raise disease resistance to achieve the effects of protect the seedlings of ginseng, increasing the yield, and raising the quality, wherein the seedlings survival rate of ginseng is raised by more than 30%, the yield of ginseng is raised by 30-50%, and the total saponins content of ginseng is equivalent to that of the ginseng cultivated in fresh forest soil. The soil conditioner has the advantages of scientific and reasonable formula, no organic chemical pesticide included, and no pollution to the soil and environment, and can ensure the green cultivation of ginseng in old ginseng fields.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a soil conditioner for old ginseng fields. Background technique [0002] The soil where ginseng has been planted for more than one crop is called old ginseng land. As a "bottleneck" limiting factor in the field of ginseng cultivation, the problem of old ginseng land has not been completely resolved so far. This not only restricts the production method of ginseng, prevents some modern cultivation methods from being applied to production practice, but also limits the source of ginseng land to the original practice of "cutting forests and planting ginseng", which greatly destroys the ecological balance of the ginseng area. At present, there are mainly the following understandings about the obstacle factors of continuous cropping of old ginseng:①The increase of pathogenic microorganisms. ② Soil physical and chemical properties deteriorate. ③ Changes in soil micro...

As a "bottleneck" limiting factor in the field of ginseng cultivation, the problem of old ginseng land has not been completely resolved so far

This not only restricts the production method of ginseng, prevents some modern cultivation methods from being applied to production practice, but also restricts the source of ginseng land to the original practice of "cutting forests and planting ginseng", which greatly destroys the ecological balance of the ginseng area.
