Embodiment 1

[0011] Group A: Step 1: According to the weight ratio of glucosamine, water, potassium sorbate and D-isoascorbic acid of the vitamin C group of 1:40:0.16:2.8, add 1g of glucosamine to 40ml of clear water, and stir evenly was dissolved, and while it was still stirring, 0.16 g of potassium sorbate (CH 3 -CH=CH-CH=CH-COOK), add 2.8g D-isoascorbic acid of the vitamin C group, add glucosamine and stabilizer (EDTA) ethylenediaminetetraacetic acid disodium salt in a weight ratio of 1:2 Stir 2g of stabilizer evenly for 1 to 1.5 hours to completely dissolve to obtain a mixed solution.

[0012] Second step: get citric acid (C 6 h 8 o 7 ·H 2 (0) is 1: 8.5 by the weight ratio of citric acid and water, then in another container, 4g citric acid is added clear water 34ml, stirred under 20 ℃ of temperature conditions and made it dissolve in 10 minutes, obtained citric acid solution.

[0013] The third step: Slowly pour the citric acid solution prepared in the second step into the mixed s...

Embodiment 2

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

[0021] The second step: take citric acid according to the weight ratio of glucosamine and citric acid as 1: 3.5, and then add 3.5g of citric acid to 40ml of clear water in another container with a weight ratio of 1: 11.6. 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 glucosamine, potassium so...

Abstract

A chitosamine preparation for increasing the power of plant to resist disease and the yield of plant is prepared through sequentically dissolving chitosamine, potassium sorbate and VC in water in weight ratio of 1:(0.05-0.16):2.8:(35-45), stirring, dissolving citric acid in water in weight ratio of 1:(8-12), and slowly adding the solution of citric acid to above-said solution while stirring.

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 glucosamine biological 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. Glucosamine (C 6 h 14 o 4 N) n [Also known as chitosan, chitosan, scientific name (1-4)-2-amino-2-deoxy-β-D-glucan, molecular weight 216-20000]. is the chi...
