Technical Field
The invention relates to the technical field of fertilizers, in particular to a biological synergistic additive for a fertilizer capable of promoting root growth and resisting aging 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.
Alginate oligosaccharide, also called algin oligosaccharide, is a marine oligosaccharide with the degree of polymerization below 20 which is degraded by algin in brown algae cells by adopting a special degradation separation technology, and consists of beta-D- (1 → 4) -mannuronic acid and alpha-L- (1 → 4) -guluronic acid; the raw materials are from natural marine plants, so that the safety is good and the environment is friendly.
Vitamins are autotrophic to higher plants, but their metabolism is also limited when the vitamin content in the plant is below a certain level. Research shows that the application of exogenous vitamins can regulate the growth and development of plant. If exogenous vitamin can stimulate the formation and growth of plant root system, vitamin D can regulate the activity of plant peroxidase so as to stimulate the generation of some plant root system. Vitamin B1 can relieve GH3The inhibition effect on the root system of the mung bean seedling promotes the root system to be increased by 12-47%. Exogenous vitamins can protect against lipid membrane aging-induced peroxidation and thus have anti-aging effects, e.g., vitamin C treatment of wheat plants can inhibit membrane peroxidation and chlorophyll degradation of wheat flag leaf cells. Exogenous vitamins can significantly change the state of inorganic nutrition deficiency of plants, such as thiamine can eliminate adverse effects caused by zinc deficiency of tomatoes, vitamin C, B1、B6Can relieve magnesium deficiency of corn.
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.
At present, commercially available biological synergistic assistants are various in types, complex in components and diverse in functions, but the effects of promoting roots, resisting aging and the like are not obvious enough when the biological synergistic assistants are applied alone, the requirements of plant growth cannot be met, and the research on the synergistic function is relatively few when multiple biological synergistic substances are adopted for compatibility.

In the biological synergistic additive, the raw material of the brown algae oligosaccharide extracting solution is polysaccharide extracted from marine brown algae, and the brown algae oligosaccharide is prepared by directional and accurate degradation, separation and purification. The brown algae oligosaccharide is linearly composed of beta-D-mannuronic acid and alpha-L-guluronic acid, and the polymerization degree is below 20. The polymerization degrees of the brown algae oligosaccharides prepared by different degradation processes are different, and the brown algae oligosaccharides with different polymerization degrees also have obvious difference on biological activity and functions. In the application, the polymerization degree of the brown alginate oligosaccharide extracting solution is 2-8; compared with the brown algae oligosaccharide with the polymerization degree of 10-20, the brown algae 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 growth activity of plant roots and oxidation resistance.
