A conditioner for alleviating continuous cropping obstacle of ginger and application method thereof

Abstract

The invention relates to a conditioner for slowing down continuous cropping obstacles of ginger and an application method thereof. Raw materials of the conditioner comprise, by weight, 3-8% of phenylalanine, 0.5-1.5% of ferulic acid ester, 0.5-1.5% of caffeic acid, 0.5-1.5% of isoeugenol, 0.5-3% of salicylic acid, 0.5-3% of chitosan, 1-3% of borax, 2-5% of zinc sulfate, 2-5% of magnesium sulfate, 3-10% of ethanol, 1-4% of acetic anhydride and 60-85% of water. The conditioner has a simple preparation technology, is low-cost, is used to raise autotoxicity resistance of ginger plants and has good effects of conditioning growth, enhancing stress resistance and slowing down continuous cropping obstacles of ginger. In comparison with yield of a control group without the application of the conditioner, yield of a group with the application of the conditioner is increased by 10-20%.

Description

technical field [0001] The invention relates to a conditioning agent for alleviating continuous cropping obstacles of ginger and an application method thereof, belonging to the technical field of plant growth regulators. Background technique [0002] Ginger has the functions of invigorating the stomach, dispelling cold and detoxifying, and is one of the important condiments. It is a famous vegetable variety in my country and plays an important role and status in increasing farmers' income and people's lives. However, continuous cropping of ginger is not suitable. After continuous cropping of ginger, soil fertility declines, soil diseases and insect pests intensify, growth is suppressed, yield decreases, and quality declines, resulting in continuous cropping obstacles and becoming a bottleneck restricting the development of ginger industry. At present, there are few researches on the prevention and control products and technologies of ginger continuous cropping obstacles. Onl...

Problems solved by technology

[0007] Although the above two patents mainly alleviate the continuous cropping obstacles from the degradation and elimination of autotoxic substances, the effect of microbial fertilizers is unstable, and the survival rate of added microorganisms in the soil is low, which affects the performance of the effect; moreover, the chemical fertilizers released by different crops The types of toxic substances are not the same, it is difficult to solve the problem of continuous cropping obstacles for all crops with one fungal agent or product
