Abstract

The invention discloses a preparation method of a water-soluble ecological synergist for fruit and vegetable crops. The water-soluble ecological synergist is prepared from chitosan, a malic acid or a pyroligneous liquor, a fulvic acid, a biochemical fulvic acid, a seaweed gel, a xanthan gum, a sorbitan fatty acid ester and deionized water. In order to solve the technical problems of poor capacity of resistance to diseases and insect pests, environment pollution, toxicity, nocuousness, unobvious yield-increasing effect and the like in the prior art, according to the technical scheme provided by the invention, the method comprises the following steps: compounding the components in proportion so as to form three soluble concentrated colloids; evenly mixing the three soluble concentrated colloids in a stirring manner, adding the fulvic acid / the biochemical fulvic acid in certain proportion and weight and simultaneously dropwise adding a surfactant dilute solution so as to prepare a multi-component mixed colloid; and finally, forming a stable and homogeneous sol. The water-soluble ecological synergist is nontoxic and innocuous due to the good ecological environment friendliness of all the components, good and harmonious in fertilizer-medicine efficacy, good in stability and suitable for different solution environments. The actual trial shows that the water-soluble ecological synergist has obvious effects and is convenient to use and store. Thus, the water-soluble ecological synergist has a wide application range.

Description

technical field [0001] The invention relates to a preparation method of a water-soluble ecological synergist with excellent biochemical performance, containing various organic and inorganic nutrients required by fruits, vegetables and crops and antibacterial effect. Background technique [0002] Chitosan is a water-soluble amino polysaccharide polymer linear polyamine, which has natural antibacterial and antibacterial effects; wood vinegar has plant growth regulation effects, and has been widely used in food, feed, medicine, and industry. It has a wide range of uses, but there are no relevant reports on the preparation of chitin colloids in China. It can be used in agriculture to restore soil fertility, improve cultivation, improve crop yield and quality, and repel insect pests, etc., to reduce pesticides and fertilizers. effect; malic acid is often used as an additive in food and medicine; fulvic acid is the most active species of humic acid, and it is being used more and m...
