Description
Technical Field
The invention relates to a preparation method of a pesticide fertilizer, in particular to a preparation method of a pesticide fertilizer capable of reducing injury of crops caused by late spring coldness.
Background
The late spring cold is mainly caused by the reasons of long-term rainy weather, frequent invasion of cold air, or strong radiation cooling at sunny night under the cold anti-cyclone control. If the average temperature in late spring is lower than the temperature of more than 2 ℃ in ten days of the year, the weather is considered to be severe late spring cold weather, which can cause harm to agricultural production, and particularly, the harm is more severe when the temperature in the early period is higher than the temperature in the year and the temperature in the later period is lower than the temperature in the year. Simply meaning: in the process of warming up in spring and in the later spring, the temperature is obviously reduced due to the invasion of cold air, so that the crops are damaged, and the weather of 'early spring warming and late spring cold' is called late spring cold.
When the temperature is too low, protoplasm in plant cells can be frozen, ice crystals can pierce a cell membrane to damage the cells, the protoplasm in the melted plant cells flows out, the cells lose activity, and the sublimation of the ice and the evaporation of liquid water in winter finally cause the dehydration of the plant cells. And (3) mild freezing injury, only partial cells are damaged, partial young leaves are frozen, the plant can still recover growth, and when the plant is serious, a large number of cells of the plant are damaged, growing points and fruits are frozen to death, the plant cannot recover growth, and a large number of plants are withered.
Most of the existing medical fertilizers are used for promoting fruit expansion and preventing plant premature senility, the cold resistance of crops is relatively poor, the common cold resistance measures at present mainly comprise the steps of cultivating cold-resistant varieties, carrying out cold resistance exercise on the crops, using plant growth regulators such as abscisic acid or paclobutrazol and the like, reasonably irrigating, draining and the like, but the effect is not obvious in the mode of improving the cold resistance of the crops by applying fertilizers to the crops.
Therefore, the preparation method of the medical fertilizer capable of reducing the injury of crops caused by late spring coldness is needed to improve the problems.
Disclosure of Invention
The invention aims to provide a preparation method of a medical fertilizer capable of reducing crop damage caused by late spring coldness, and aims to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a preparation method of a medical fertilizer capable of reducing crop damage caused by late spring coldness comprises the steps of brassinolide extraction, mixing and stirring, disinfection and drying, fine grinding and extrusion granulation, and the specific preparation method comprises the following steps:
s1: brassinolide extraction, rape flower is taken as a raw material, rape flower is crushed and pulped, slurry is mixed and fermented, then a fermentation mixture after mixed fermentation is filtered, filtrate is collected for sterilization and disinfection, then the filtrate is concentrated and dried, then the dried filtrate is put into a crusher for crushing, 300-mesh sieve is used for sieving to obtain moss lactone powder, rape flower is taken as a raw material, rape flower is crushed and pulped, slurry is mixed and fermented, then the fermentation mixture after mixed fermentation is filtered, filtrate is collected for sterilization and disinfection, then the filtrate is concentrated and dried, the dried filtrate is put into the crusher for crushing, 300-mesh sieve is used for sieving to obtain moss lactone powder, rape flower is taken as a raw material, the cost is low, organic solvent is not required by fermentation and extraction, organic matter residue is avoided, and the cost can be reduced, the purity is improved;
s2: mixing and stirring, putting 0.001-0.002 part of brassinolide, 30-50 parts of monopotassium phosphate, 0.1-0.2 part of compound sodium nitrophenolate, 1-5 parts of wetting agent, 10-20 parts of dispersing agent, 0.5-1.5 parts of disintegrating agent and filling material into a mixer according to a ratio, uniformly mixing at 45 ℃ at 200r/min, wherein the brassinolide, the monopotassium phosphate and the compound sodium nitrophenolate are arranged, and the brassinolide is an artificially synthesized plant endogenous hormone, can promote root growth, improve photosynthesis and improve the stress resistance of plants, is an artificially synthesized plant growth regulator, is a strong cell activator, can promote the protoplasm flow of cells, improve the activity of the cells and remarkably improve the performance of the crops, can improve the phosphorus and the potassium required for the crop growth, can also improve the activity of the cells, promotes proteins, saccharides and the potassium phosphate, The compound sodium nitrophenolate is a cell activator, the activity of cells can be improved, as long as the plants have physiological functions, the compound sodium nitrophenolate can play a role, the crops can be promoted to quickly recover growth, the three components can promote the photosynthesis of the plants, the absorption and transformation utilization of nutrient substances by the plants are accelerated, the concentration of protoplasm in the cells is obviously improved, the compound use of the compound sodium nitrophenolate can improve the activity of the cells, the photosynthesis capacity of the crops is quickly improved, the activity of various enzymes in plant cells is promoted, the synthesis of substances such as protein, amino acid and the like is accelerated, the leaves are thicker, the concentration of the protoplasm in the cells is improved, the cold resistance of the plants is obviously improved, the medical fertilizer can promote fruit expansion, prevent premature senility of the plants and obviously improve the cold resistance of the plants;
s3: sterilizing and drying, namely putting the mixture into a sterilizing and drying machine, and drying and sterilizing for 1h at 85 ℃;
s4: fine grinding, namely putting the dried mixture into a jet mill to be ground to be more than 800 meshes;
s5: extruding and granulating, namely putting airflow powder of more than 800 meshes into a kneader, adding 10-20% of water, stirring for 20 minutes, discharging wet materials, putting the wet particles into the extruding and granulating machine, drying the obtained wet particles in an oven at 80 ℃, sieving the dried particles by a vibrating screen, extracting the particles of 10-60 meshes into finished products, returning the sieved products to a crushing system, uniformly mixing brassinolide, wetting agent, dispersing agent, disintegrating agent and filling material, performing superfine crushing to obtain particles of more than 800 meshes (the particle size is equivalent to 0.015mm), and extruding and granulating to obtain soluble particles.
