A kind of biological liquid fertilizer enriched with Moringa polysaccharide and preparation method thereof

Abstract

The invention discloses a moringa oleifera polysaccharide-rich biological liquid fertilizer and a preparation method thereof. The fertilizer comprises the following components in parts by weight: 5-15 parts of moringa oleifera polysaccharide, 10-25 parts of gamma-polyglutamic acid, 3-8 parts of attapulgite, 3-8 parts of a moringa oleifera protein nutrient solution, 10-20 parts of bacillus megatherium liquid, 5-15 parts of bacillus subtilis liquid, 5-15 parts of bacillus licheniformis liquid, 5-15 parts of actinomycetes liquid, 5-15 parts of lactobacillus plantarum liquid and 5-15 parts of photosynthetic bacterium liquid. According to the preparation method, liquid fermentation is carried out on moringa oleifera polysaccharide, gamma-polyglutamic acid and the other components to obtain the fertilizer. According to the moringa oleifera polysaccharide-rich biological liquid fertilizer, the probiotic components and other organic nutrient components contained in the fertilizer can give play to an obvious synergistic effect, and compared with a separate probiotic component fertilizer and a separate organic nutrient component fertilizer, the moringa oleifera polysaccharide-rich biological liquid fertilizer can promote the yield of crops to be increased by around 15% and 25% respectively; besides, the using method is various, root and seedling strengthening of crops can be quickly promoted, the quality of crops is improved, and compared with an ordinary fertilizer, the fertilizer can promote the yield of agricultural products to be increased by around 20%.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a biological liquid fertilizer enriched with Moringa polysaccharide and a preparation method thereof. Background technique [0002] Since the long-term use of chemical fertilizers will damage the proper flora structure of the soil and the aggregate structure of the soil, in order to protect the ecology and fertility of the soil, the use of microbial fertilizers is becoming more and more widespread. However, most of the existing liquid microbial fertilizers on the market are single biological probiotic fertilizers, such as nitrogen-fixing bacteria fertilizers, phosphorus bacteria and potassium bacteria, etc. These fertilizers can only meet the needs of crops for a single nutrient when used alone, and the cost is high. If the dosage is large, it is difficult to achieve a reasonable combination and a scientific ratio if used in combination, so the fertilizer effect of the fertilize...

Problems solved by technology

However, most of the existing liquid microbial fertilizers on the market are single biological probiotic fertilizers, such as nitrogen-fixing bacteria fertilizers, phosphorus bacteria and potassium bacteria, etc. These fertilizers can only meet the needs of crops for a single nutrient when used alone, and the cost is high. The dosage is large, if used in combination, it is difficult to achieve a reasonable combination and a scientific ratio, so the fertilizer effect of the fertilizer cannot be well exerted

[0003] A good biological fertilizer has strict requirements on the number of effective viable bacteria, the rate of miscellaneous bacteria, and the effective storage period. In order to increase the nitrogen, phosphorus and potassium content in fertilizers, some manufacturers add inappropriate amount of chemical fertilizers or additives, resulting in the death of effective bacteria, losing the role of biological fertilizer, and bringing losses to agricultural production.
