Anti-adversity agent and its preparation method and application

Abstract

The invention relates to an anti-stress agent and a preparation method and application thereof. The anti-stress agent is composed of components with the following mass concentrations: 5g / L-8g / L highly active humic acid, 10g / L-20g / L Concentrated molasses fermentation broth, 4g / L-6g / L nitrogen source, 2g / L-4g / L phosphorus source, 1g / L-3g / L potassium source, 8g / L-12g / L magnesium and 3- 5g / L of trace elements, wherein the highly active humic acid is prepared by alkaline hydrolysis and nitration, and the trace elements are composed of zinc, iron, boron and molybdenum. The anti-stress agent can activate soil nutrients and retain nutrients through the compounding of various components, produce binding effect and competition effect between elements, can improve the effectiveness and slow-release performance of the anti-stress agent, and significantly increase crop yield.

Description

technical field [0001] The invention relates to an anti-adversity agent and its preparation method and application. Background technique [0002] There are two ways for crops to absorb nutrients: one is root absorption, and the other is leaf absorption. Foliar fertilization is a supplementary fertilization method commonly used in production, that is, through foliar spraying to supplement the nutrients needed by plants, and play a role in regulating plant growth, supplementing deficient elements, preventing premature aging and increasing production. . [0003] At present, most of the anti-stress agents sold in the market are foliar fertilizers, which contain plant growth regulators, and are mainly formulated according to the adverse symptoms that crops are prone to occur, and their functions are relatively single. Plant growth regulators can only be used during certain periods of crop growth. However, crops are affected by their own internal factors and external factors su...

AI Technical Summary

Problems solved by technology

However, crops are affected by their own internal factors and external factors such as soil, fertilizer, water, climate, pests, and management during the whole growth process. It is impossible to have only one adverse symptom at the same time, especially during the growth process. In unfavorable environments such as drought, pest damage, etc., improper fertilization and pesticide application cause fertilizer damage, phytotoxicity and crop deficiency, etc., which often cause greater losses to agricultural production and lower yields.

[0004] At present, there is no anti-stress agent that can be used for both soil application and foliar spraying; it can not only supplement crop nutrition, solve crop element deficiency caused by unreasonable fertilization, and alleviate fertilizer damage caused by improper fertilization and pesticide application. It can also regulate, induce and stimulate the crop's own defense ability, enhance the crop's anti-adversity ability such as cold resistance, drought resistance, and humidity resistance, and ensure the balanced and robust growth of crops, so as to finally achieve the goal of increasing yield.
