Nutrient for enhancing plant growth and preparation method thereof

Abstract

The invention relates to a nutrient for enhancing plant growth and a preparation method thereof. The nutrient comprises the following components in percent by weight: 20-80 percent of nucleotide salts and deoxynucleotide salts and 20-80 percent of sugar or amino acid. The preparation method comprises the following steps of: preparing nucleic acid from mycelium in side products of a fermentation plant, next, hydrolyzing the nucleic acid into the nucleotide salts and the deoxynucleotide salts, and then mixing the nucleotide salts and the deoxynucleotide salts with the sugar or amino acid. The invention has the advantages that (1) the nutrient has no toxicity, harm, residue and any adverse side effect to plants; (2) the nutrient is beneficial to increase of the yield, the income and the efficiency, and has good effects of enhancing the resistance and improving the quality for plants; and (3) the preparation method has a simple process and low cost and is easy for large-scale production and promotion. The nutrient is widely applied to plants such as grain crops, cotton crops, oil crops, tobaccos, tea trees, fruit trees, vegetables, mushrooms, Chinese medicinal plants, flowers, forests and the like.

Description

technical field [0001] The invention relates to a nutrient for promoting plant growth, in particular to a fertilizer for promoting crop growth and a preparation method thereof. Background technique [0002] Vigorously developing planting and forestry, increasing crop production and income, and greening the motherland are issues that scientists from all over the world are concerned about. The growth of plants is inseparable from supplementary nutrition. The current planting industry mainly relies on the application of nitrogen, phosphorus, potassium fertilizers and organic fertilizers. To promote the growth of crops, excessive application of fertilizers has a great impact on the quality and flavor of crops, which is not conducive to the development of green agriculture, food safety and environmental protection. Therefore, people have studied auxins, nutrients, and fertilizers related to nucleic acids. Theoretically speaking: Nucleic acid is the basic substance of life and th...

Problems solved by technology

Chinese patent literature (publication number: 101186534) discloses a preparation method of foliage fertilizer containing nucleic acid degradation products, the specific steps are: ①, leaching nuclease, ②, dissolving ribonucleic acid (lye solution), ③, nucleic acid The hydrolysis of nucleosides, nucleotides, purines, pyrimidines and other small nucleic acid molecules and a small amount of reducing sugars and very few large, medium and trace elements. This method uses ribonucleic acid as raw material and enzymatic hydrolysis. High production cost, incomplete degradation, very little deoxynucleotide content, low nucleotide salt yield in the mixed system, imbalanced ratio of various nucleotide salts and deoxynucleotide salts, which greatly affects the use effect

Chinese patent document (publication number: 101050143) discloses a nutrient that promotes the growth of crops, which is composed of ribavirin and glucose. The production of ribavirin is closely related to guanosine. The cost of ribavirin in this patent is too high , the problem that the actual use effect is not obvious; Chinese patent literature (publication number: 1238323) discloses a preparation method of nucleic acid foliar fertilizer, the degradation of its nucleic acid adopts the method of alkaline hydrolysis, and the degradation products are purine and pyrimidine. There are also problems that the cost of nucleic acid is too high, and the ratio of various nucleotide salts and deoxynucleotide salts is unreasonable, which affects the use effect.
