Peanut successive cropping obstacle conditioner based on allelopathic autotoxicity effect and application method thereof

Abstract

The invention discloses a peanut successive cropping obstacle conditioner based on the allelopathic autotoxicity effect and an application method thereof. The conditioner is composed of, by mass, 3%-10% of phenylalanine, 0.2%-1% of o-tert-butyl phenol, 0.2%-1% of 3,5-dimethylbenzoic acid, 0.2%-1% of isoeugenol, 0.5%-3% of salicylic acid, 0.3%-1% of borax, 0.3%-1% of sodium molybdate, 0.5%-3% of zinc sulfate, 0.5%-3% of ferrous sulfate, 0.5%-3% of manganese sulfate, 3%-10% of ethyl alcohol and 65%-90% of water, wherein the mass percent sum of all the components is 100%. The conditioner is simple in preparation technology and low in cost. The self-poison resistance of peanut plants is improved; meanwhile, growth is conditioned, the stress resistance is enhanced, the peanut successive cropping obstacle solving effect is good, and the yield is increased by 15%-20% compared with a control group to which the conditioner is not applied.

Description

technical field [0001] The invention relates to a peanut continuous cropping obstacle conditioning agent based on allelopathic autotoxicity and an application method thereof, belonging to the technical field of plant growth regulators. Background technique [0002] Peanut is an important economic oil crop in my country. Due to the influence of ecological conditions and the adjustment of agricultural planting industry structure, the continuous cropping area of ​​main peanut production areas is increasing. Peanut is a sensitive crop to continuous cropping. The annual pod yield is reduced by 19.8% to 33.4%. The obstacle of continuous cropping of peanut has become an important factor restricting the development of my country's peanut industry and the safety of grain and oil. Focusing on the mitigation of peanut continuous cropping obstacles, predecessors have conducted research on cultivation methods, special fertilizers for peanuts, and resistant bacterial agents, and applied fo...

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
