Problems solved by technology

However, at present, in the preparation of domestic shell oligosaccharide biopesticides and organic fertilizers, most people use acetic acid solution to dissolve and neutralize it with sodium benzoate as a preservative. The anti-decomposition ability is low, which leads to short shelf life, insufficient efficacy and high cost. Problems that affect promotion and application

Embodiment 1

[0011] Group A: Step 1: Add 1g of chitosan to 40ml of water and stir evenly When it is still in a stirring state, add 0.16g potassium sorbate (CH3-CH=CH-CH=CH-COOK), add 2.8g D-isoascorbic acid of the vitamin C family, press chitosan and stabilize Agent (EDTA) ethylenediaminetetraacetic acid disodium salt weight ratio is 1:2, add 2g of stabilizer, stir evenly for 1-1.5 hours, make it dissolve completely to obtain a mixed solution.

[0012] The second step: take citric acid (C6H807·H2O) as 1: 4 by chitosan and citric acid weight ratio, be 1: 8.5 by the weight ratio of citric acid and water, then in another container, put 4g citric acid Add 34ml of clear water, stir at 20°C for 10 minutes to dissolve it, and obtain a citric acid solution.

[0013] The third step: slowly pour the citric acid solution prepared in the second step into the D-isoascorbic acid mixed solution of chitosan oligosaccharide, potassium sorbate and vitamin C family prepared in the first step in the stirring...

Embodiment 2

[0020] The first step: according to the weight ratio of chitosan oligosaccharide, water, potassium sorbate and ascorbic acid vitamin C, which is 1:35:0.08:2.8, add 1g of chitosan oligosaccharide to 35ml of clear water, stir evenly to dissolve, and when it is still in the When stirring, add 0.08g potassium sorbate, add 2.8g ascorbic acid vitamin C, add stabilizer 1g according to the weight ratio of chitosan and stabilizer (EDTA) ethylenediaminetetraacetic acid disodium salt is 1:1, stir evenly 1 to 1.5 hours to completely dissolve it to obtain a mixed solution.

[0021] Second step: take citric acid as 1: 3.5 by weight ratio of chitosan and citric acid, and 1: 11.6 by weight ratio of citric acid and water, then in another container, add 3.5g of citric acid to 40ml of clear water, Stir at 20°C for 10 minutes to dissolve it to obtain a citric acid solution.

[0022] The third step: slowly pour the citric acid solution prepared in the second step into the mixed solution of chitos...

Abstract

A Chitosan oligosaccharide immunization yield increase agent and its preparation method relate to a biological fertilizer and a biological agricultural agent formula and its preparation method. According to the invention, the weight ratio of Chitosan oligosaccharide to water to potassium sorbate to ascorbic acid vitamin C is 1: (35-45): (0.05-0.16): 2.8. The preparation method provided by the invention comprises the following steps of: dissolving the Chitosan oligosaccharide in water with stirring, adding the potassium sorbate into the solution, followed by the addition of the ascorbic acid vitamin C with stirring; taking citric acid according to the weight ratio of Chitosan oligosaccharide to citric acid being 1: (3-4), and dissolving the citric acid in water according to the weight ratio of citric acid to water being 1: (8-12) to obtain a citric acid solution; slowly pouring the citric acid solution into the mixed solution which is in a stirring state, bottling and capping. The adoption of the yield increase agent provided by the invention leads to excellent effect in some aspects such as crop seed soaking, insect disease controlling, fruit and vegetable fresh-keeping, soil improvement, fertilizer slow-releasing and feed additive and the like.

Description

(1) Technical field: [0001] The invention relates to a formula of biological fertilizer and biological pesticide and a preparation method thereof. (two) background technology: [0002] As the world's largest chemical fertilizer application country and the second largest chemical pesticide application country, China's large or excessive application of chemical fertilizers and chemical pesticides has not only caused environmental pollution, but also seriously restricted the development of modern green agriculture. In order to solve this problem, researchers have actively researched and developed chitosan oligosaccharide biomedical fertilizers in recent years, and have made many progresses in crop seed soaking, pest control, fruit and vegetable preservation, soil improvement, slow release of chemical fertilizers, and feed additives. Oligochitosan (C 6 h 14 o 4 N)n [also known as chitosan, chitosan], scientific name (1-4)-2-amino-β2-deoxy-β-D-glucan, molecular weight 216-2000...
