Abstract
The invention provides a fertilizer synergist and application thereof in fertilizer preparation, and belongs to the technical field of fertilizer preparation. The fertilizer synergist disclosed by the invention is prepared from 15-28 parts of pericarpium Granati, 7-14 parts of polyaspartic acid, 6-9 parts of castor oil polyoxyethylene ether, 1-4 parts of lecithin, 3-6 parts of guar gum, 5-10 parts of amino acid chelating liquid and 4-8 parts of compound enzyme in parts by weight, and can be applied together with the fertilizer, so that the fertilizer utilization rate can be effectively improved, the fertilizer consumption can be saved, the environmental pollution can be reduced, the crop yield can be effectively improved, and the preparation method is simple and suitable for large-scale popularization and production.
Description
Technical Field
The invention belongs to the technical field of fertilizer preparation, and particularly relates to a fertilizer synergist and application thereof in fertilizer preparation.
Background
Chemical fertilizers occupy a serious role in agricultural production, because the growth of crops is free from chemical elements, some elements are obtained in soil, some elements are derived from air, the elements are essential in the growth process of the crops, the crops can not grow well due to the lack of the elements, and the crops in different areas are more or less deficient in growth elements due to the influence of climate and geography, so that the application of chemical fertilizers is the most common technical means for improving the growth condition of the crops.
However, any fertilizer cannot be fully absorbed and utilized by crops after being applied to the soil, and a part of the fertilizer is unavailable to the crops due to leaching, volatilization or fixation by the soil. Meanwhile, the fertilizer utilization rate is low, so that the dosage is increased to realize high yield per unit, however, the defect caused by low utilization rate is overcome by simply increasing the fertilizer dosage, unbalance of plant nutrient elements in soil is further caused, the crop yield is reduced, the crop quality is deteriorated, and the energy source, the resource waste and the economic loss are caused, and the environment is also deteriorated. Therefore, improving the utilization rate of chemical fertilizers and avoiding environmental pollution caused by excessive fertilization has become a urgent problem to be solved in developing sustainable agriculture.
Based on the technical problems, a chemical fertilizer synergist is needed to be provided and applied to chemical fertilizer preparation.
Disclosure of Invention
In order to solve the technical problems, the invention provides a fertilizer synergist and application thereof in fertilizer preparation.
According to one of the technical schemes, the chemical fertilizer synergist comprises, by weight, 15-28 parts of pericarpium Granati, 7-14 parts of polyaspartic acid, 6-9 parts of castor oil polyoxyethylene ether, 1-4 parts of lecithin, 3-6 parts of guar gum, 5-10 parts of amino acid chelating liquid and 4-8 parts of compound enzyme.
Further, the raw materials of the fertilizer synergist also comprise bacillus subtilis, and the addition amount of the bacillus subtilis is 1-4% of the mass of the pomegranate rind.
Further, the amino acid chelate liquid comprises one or more of amino acid chelate boron, amino acid chelate zinc and amino acid chelate iron.
Further, the complex enzymes include cellulases, bromelain, spirulina enzymes and soybean proteases.
Further, the mass ratio of the cellulase to the pineapple enzyme to the spirulina enzyme to the soybean protease in the complex enzyme is (1-3) to (2-4) to 3 to (2-4).
The second technical scheme of the invention is that the preparation method of the fertilizer synergist comprises the following steps:
weighing raw materials according to parts by weight, drying and crushing pericarpium Granati to obtain pericarpium Granati particles, adding the pericarpium Granati particles into a mixed solution of castor oil polyoxyethylene ether and amino acid chelating liquid, stirring and soaking, taking out the soaked pericarpium Granati particles, standing and airing, mixing and granulating with lecithin, guar gum, complex enzyme and bacillus subtilis to obtain solid particles, and then spraying polyaspartic acid on the surfaces of the solid particles to obtain the fertilizer synergist.
Further, the pericarpium Granati is dried until the water content is less than 5%, and is crushed to 50-100 meshes to obtain pericarpium Granati particles.
Further, the polyaspartic acid is diluted by water to the concentration of 30-50wt% and then sprayed, the spraying pressure is 0.6-0.8MPa, and the spraying temperature is 38-45 ℃.

9 mu of land is selected, 9 blocks are evenly divided into 1 mu of land, 4 of land are used as test fields, the base fertilizers are respectively applied with fertilizers added with the fertilizer synergists prepared in the examples 1-4, the application amount is 20 kg/mu, the other 4 land are used as control fields, the 4 land are respectively applied with fertilizers added with the fertilizer synergists prepared in the comparative examples 1-4, the application amount is 20 kg/mu, the other land is blank control field, only the smini compound fertilizer is applied, and the application amount is 35 kg/mu. After the wheat is turned green, the test field and the control field are coated with 12 kg/mu of urea, and the blank control field is coated with 20 kg/mu of urea. Other field management methods are the same.
Statistical yield results after wheat harvesting are shown in table 1.
TABLE 1 wheat yield statistics
As can be seen from table 1, under the condition that the application amount of fertilizer and urea is smaller than that of a blank control field, the per mu yield of wheat planted and harvested is increased by 76 jin, the yield is increased by 11%, and meanwhile, the per mu spike number, the per spike number and the thousand grain weight of wheat are effectively improved.
