Embodiment 1

[0033] A fertilizer for preventing and treating low-temperature disasters. The raw materials in parts by weight include: 20 parts of potassium feldspar, 10 parts of phosphogypsum, 37 parts of chestnut flower extract, 9 parts of earthworm extract, 23 parts of Radix isatidis extract, and 25 parts of fermented grape skin 45 parts of rice bran ash enzymatic hydrolyzate, 500 parts of water;

[0034] The chestnut flower extract is obtained by refining the ratio of chestnut flower and water at a ratio of 1:7 at a low temperature of 10°C to obtain fresh bark sap. Homogenize 3 times under the pressure of 300MPa, and then homogenize once under the condition of 80MPa to obtain fresh bark emulsion;

[0035] The earthworm extract is prepared by mixing earthworms with acetic acid solution, the ratio of solid to liquid is 1:8, heating up to 170° C. under 3 atmospheres, decomposing for 2 hours with heat preservation, and filtering after completion to obtain the earthworm extract;

[0036] Th...

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...
