Embodiment 1

[0012] Group A: Step 1: Add 1g of chitosan to 60ml of water at 25°C according to the weight ratio of chitosan, water, and weight ratio: 1:60:, stir evenly to dissolve, and when it is still in the stirring state, According to the weight ratio of chitosan and stabilizer (EDTA) ethylenediaminetetraacetic acid disodium salt as 1:2, add 2g of stabilizer, stir evenly for 20-30 minutes, and make it dissolve completely to obtain a mixed solution.

[0013] 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.

[0014] The third step: slowly pour the citric acid solution prepared in the second step into the mixed solution of chitosan and water prepared in the first step in the stirring state, and continue to stir for 1 hour. After the chitosan is complet...

Abstract

The invention discloses a chitosan plant disease-resistant seed-dressing agent and a preparation method thereof, which belong to the formulations of biological fertilizers and biological pesticides and preparation methods thereof. The preparation method comprises the following steps: dissolving chitosan in water according to the weight ratio of the chitosan to water being 1: (70-90), wherein the temperature is controlled to be 20 DEG C; uniformly stirring for 20-30 minutes so that the chitosan is dissolved to obtain a mixed solution; preparing citric acid according to the weight ratio of the chitosan to the citric acid being 1: (3-4), dissolving the citric acid in water under the condition that the weight ratio of the citric acid to the water is 1: (4-6), stirring 5-10 minutes at a temperature of 20 DEG C, so that the citric acid is dissolved and then a citric acid solution is obtained; slowly pouring the citric acid solution prepared in the step 2 into the chitosan-water mixed solution obtained in the step 1 and in a stirred state, continuing to stir 2 hours, after the mixed solution is fully dissolved, adding a bactericide into the mixed solution in a stirred state under the condition that the weight ratio of the mixed solution to the bactericide is 1: (0.1-0.2), so that the bactericide is fully dissolved; and carrying out bottling and cap sealing. The seed-dressing agent achieves beneficial effects on the aspects of crop seed dressing, pest control, disease resistance enhancing, 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. 2. Background technology [0002] For the high yield and harvest of crops, the treatment of seeds during sowing is very important, especially the treatment of crop seeds with chemical pesticides (fungicides or insecticides) has many advantages, one is beneficial to seedling preservation; the other is beneficial to increase production; the third is It is beneficial to prevent the spread of seed-borne diseases and insect pests. Generally speaking, in order to prevent and control pests and diseases at the seedling stage of crops, most farmers in our country will use traditional methods and conventional chemical pesticides to dress seeds before sowing. Although this approach can play a certain role and preventive effect, there are many shortcomings. The first is that most seed dressing agents belong to the highly toxic type, such as 39...
