Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a biological synergistic additive for a fertilizer for promoting photosynthesis and preventing physiological yellowing and a preparation method thereof.
Background
In recent years, agriculture in China advocates fertilizer saving, efficiency improvement, quality improvement and green development so as to solve the problems of resource waste, environmental pollution and the like caused by unreasonable application of chemical fertilizers. The fertilizer biological synergistic additive has the effects of improving the growth environment of crops, stimulating the growth of crops, improving the utilization efficiency of fertilizer, reducing the using amount of fertilizer and the like, and raw materials of the fertilizer biological synergistic additive are mostly derived from natural renewable resources, do not pollute the environment, accord with the green development direction of national agriculture, and are paid attention by a plurality of scholars and favored by consumers. However, the biological fertilizer synergist has various varieties, complex components and poor effect, and limits the popularization and application of the biological fertilizer synergist.
The biological synergistic additive is non-toxic and harmless to people and livestock, has no pollution to the environment, and has the advantages that any other chemical synergistic additives cannot be compared. The fertilizer is matched with nitrogen, phosphorus, potassium and other compound fertilizers for use, can improve the nutrient absorption and utilization efficiency, regulate the growth of plants, and improve the yield and quality of crops, and particularly has more obvious yield increase effect when being applied to fruit trees and vegetables.
However, currently, commercially available biological synergistic additives are various in types, complex in components and diverse in functions, but the effects of promoting photosynthesis, preventing physiological yellowing and the like are not prominent enough when the biological synergistic additives are applied alone, the plant growth requirements cannot be met, and the research on the synergistic function of the biological synergistic substances is relatively few.
Disclosure of Invention
The invention aims to provide a biological fertilizer synergistic auxiliary for promoting photosynthesis and preventing physiological yellowing.
In view of the above, the present application provides a biological synergistic additive for fertilizer, which can promote photosynthesis and prevent physiological yellowing, comprising:
preferably, the chitosan content of the chitosan extract with the polymerization degree of 3-7 is more than or equal to 90%, and the solid content is more than or equal to 15%.
Preferably, the content of the alginate-derived oligosaccharide with the degree of polymerization of 2-8 in the alginate-derived oligosaccharide extracting solution is more than or equal to 90%, and the solid content is more than or equal to 15%.
Preferably, the content of the chitosan extract is 32-37 parts by weight.
Preferably, the content of the seaweed oligosaccharide extracting solution is 33-38 parts by weight.
Preferably, the content of the EDTA chelated iron is 1.0-3.5 parts by weight.
Preferably, the boric acid is contained in an amount of 1.0 to 3.5 parts by weight.
Preferably, the content of the alanine is 1.2-3.8 parts by weight, the content of the cysteine is 1.0-3.5 parts by weight, the content of the histidine is 1.2-4.0 parts by weight, the content of the lysine is 1.0-3.8 parts by weight, and the content of the glycine is 1.2-4.5 parts by weight.
Preferably, the content of manganese sulfate is 1.0-4.0 parts by weight, the content of magnesium sulfate is 3-7 parts by weight, and the content of zinc sulfate is 4-8 parts by weight.
The application also provides a preparation method of the biological fertilizer synergist, which comprises the following steps:
mixing chitosan oligosaccharide extract, brown algae oligosaccharide extract, alanine, cysteine, histidine, lysine, glycine, EDTA chelated iron, boric acid, manganese sulfate, magnesium sulfate and zinc sulfate in proportion, and adjusting the pH value to 3-4 to obtain a mixed solution;
and dispersing and emulsifying the mixed solution, and then spraying and drying to obtain the biological synergistic additive of the fertilizer.
The application provides a biological synergistic additive for a fertilizer, which comprises chitosan extracting solution, seaweed oligosaccharide extracting solution, alanine, cysteine, histidine, lysine, glycine, EDTA chelated iron, boric acid, manganese sulfate, magnesium sulfate and zinc sulfate in a specific proportion. According to the fertilizer biological synergistic additive, the specific components are adopted, the content of the components is adjusted, the heat sensitive components are effectively prevented from being damaged, the growth of plant root systems can be promoted when the fertilizer biological synergistic additive is applied to plants, the nutrient absorption and transportation efficiency of the root systems is improved, and the yellowing phenomenon caused by the loss of plant silver nutrients is prevented; meanwhile, synthesis of plant chlorophyll can be promoted, photosynthetic efficiency of leaves is improved, and fruit yield is effectively improved.
Detailed Description
For a further understanding of the invention, reference will now be made to the preferred embodiments of the invention by way of example, and it is to be understood that the description is intended to further illustrate features and advantages of the invention, and not to limit the scope of the claims.
In view of the deficiency of the performance of the fertilizer synergistic assistant for promoting photosynthesis and preventing physiological yellowing in the prior art, the application provides the fertilizer synergistic assistant for promoting photosynthesis and preventing physiological yellowing. Specifically, the application provides a fertilizer biological synergistic additive for promoting photosynthesis and preventing physiological yellowing, which comprises:
in the biological synergistic additive, the polymerization degree of the seaweed oligosaccharide extracting solution is 2-8; the seaweed oligosaccharide with the polymerization degree of 2-8 has small molecular weight, is not easy to flocculate and precipitate, is easier to be absorbed by plants, and has more remarkable effects of promoting the photosynthesis of the plants and preventing physiological yellowing. The alga oligosaccharide is similar to plant hormone, can stimulate the growth of root systems and stem leaves of crops, and improves the yield of the crops; can induce plants to generate resistance, improve the oxidation resistance of the plants and delay the crop aging.
