Fertilizer for preventing and treating low-temperature disasters and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer production, and particularly relates to a fertilizer for preventing and treating low-temperature disasters and a preparation method thereof.The fertilizer comprises the following raw materials in parts by weight: 16-20 parts of potassium feldspar, 6-10 parts of phosphogypsum, 33-37 parts of a chestnut flower extraction matter, 7-9 parts of an earthworm extraction solution, 21-23 parts of an isatis root extraction matter, 21-25 parts of a grape skin fermentation matter, 41-45 parts of a rice bran ash enzymolysis matter, and 400-500 parts of water. By carrying out extraction and decomposition on natural substances, the purpose of adjusting osmotic balance of crops can be achieved, at the same time, beneficial microorganisms are attracted to gather in the root system, vitality of the root system can be improved, absorption is promoted, accumulation of superoxide radicals in crop cells is beneficial to be cleared, damage of membrane lipid peroxidation is reduced, and at the same time, antioxidants are used, activity of the enzyme system is protected, and breeding of pathogenic bacteria is inhibited, so that the ability of thecrops to resist low temperature stress is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a fertilizer for preventing and controlling low-temperature disasters and a preparation method thereof. Background technique [0002] Low temperature is a natural disaster, usually from October to March of the following year, due to the influence of strong cold air or extreme heavy snow, the temperature suddenly drops sharply. The low temperature disaster refers to the limitation of the physiological activities of the plants when the temperature drops below the lower limit temperature of the growth and development stage of the plants at that time, so that the life activities of the plants are exhausted. The intensity and duration of low temperature directly determine the intensity of damage to plants. [0003] Patent No. CN201811383565.7 discloses a composition that has anti-stress potential mobilization and root cap pressure-promoting functions for cro...

Problems solved by technology

Although trace element fertilizers have the functions of activating soil nutrients, improving soil physical and chemical properties, increasing soil beneficial microorganisms, inhibiting the types and activities of harmful pathogens, and can significantly improve the yield and quality of agricultural and forestry crops after application, the materials for preparing trace element fertilizers are mostly distributed and scattered. , the extraction rate of nutrient content is low, and the cost of collection, transportation and use is high, so it is greatly limited as a high-quality fertilizer. It is very important to seek and develop low-cost, high-nutrient fertilizers
