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.

Example Embodiment

[0009] Example 1: Mix 10-20 grams of malic acid with deionized water to form an aqueous solution with an acid concentration of 5%-20% by weight, and add chitin with a degree of deacetylation of 60%-90% and a molecular weight of 1000-2000. 5-10 grams of substance, heated to 50°C-80°C and at the same time fully stirred until completely dissolved, it becomes a light yellow transparent colloid.

[0010] Combine seaweed gum with xanthan gum, according to the ratio of fulvic acid/biochemical fulvic acid respectively, 5-10 grams by weight to form an aqueous solution with a concentration of 2wt%-10wt% at 30℃-50℃ Stir fully to prepare a uniform viscous gel.

[0011] The fulvic acid and biochemical fulvic acid are prepared into an aqueous solution with a concentration of 2wt%-10wt% in a ratio of 5:1, and fully stirred at 30°C-50°C to prepare a uniform viscous colloid.

[0012] Mix 0.5-1 g of sorbitan fatty acid ester (nonionic surfactant Tween 80) with 10-20 times deionized water and stir to form a dilute solution of nonionic surfactant. Mix the aforementioned three solution colloids with the dilute non-ionic surfactant solution, stir for 20-30 minutes while adding 20-100 grams of deionized water gradually to form a stable and uniform concentrated synergist solution, and leave it to stand for defoaming.

Example Embodiment

[0013] Example 2: Mix 10-20 grams of malic acid with deionized water to form an aqueous solution with an acid concentration of 5%-20% by weight, and add a degree of deacetylation of 60%-90%, a molecular weight of 1000-2000, 4000- 5000, 6000-8000, 10000-12000 four kinds of chitin, each in a 1:1 ratio mixture of 5-10 grams, heated to 50-80 ℃ and at the same time fully stirred until completely dissolved, and become a light yellow transparent colloid.

[0014] Mix seaweed gum with xanthan gum, the ratio of seaweed gum/xanthan gum is 1/1, and the weight is 1-5 grams to form an aqueous solution with a concentration of 2wt%-10wt%. Stir fully at 30℃-50℃ to prepare Into a uniform viscous colloid.

[0015] The fulvic acid and biochemical fulvic acid are prepared into an aqueous solution with a concentration of 2wt%-10wt% in a ratio of 5:1, and fully stirred at 30°C-50°C to prepare a uniform viscous colloid.

[0016] Mix 0.5-1 g of sorbitan fatty acid ester (nonionic surfactant Tween 80) with 10-20 times deionized water and stir to form a dilute solution of nonionic surfactant. Mix the aforementioned three solution colloids with the dilute non-ionic surfactant solution, stir for 20-30 minutes while gradually adding 20-100 grams of deionized water to form a stable and uniform concentrated synergist solution, and leave it to stand for defoaming.

Example Embodiment

[0017] Example 3: In 5-10 grams of chitin with a degree of deacetylation of 60%-90% and a molecular weight in the range of 1000-2000, add wood vinegar with a weight of 40-80 grams and heat it at 40°C-50°C. Stir to completely dissolve and become a light yellow to light brown colloid.

[0018] Combine seaweed gum with xanthan gum, make up an aqueous solution with a concentration of 2wt%-10wt% at a concentration of 2wt%-10wt% according to the ratio of 1/1, a weight of 1-5 grams of seaweed gum/xanthan gum, and stir it thoroughly at 30℃-50℃. Into a uniform viscous colloid.

[0019] The fulvic acid and biochemical fulvic acid are prepared into an aqueous solution with a concentration of 2wt%-10wt% in a ratio of 5:1, and fully stirred at 30°C-50°C to prepare a uniform viscous colloid.

[0020] Mix 0.5 g of sorbitan fatty acid ester (nonionic surfactant Tween 80) with 10-20 times deionized water and stir to form a dilute solution of nonionic surfactant. Mix the aforementioned three solution colloids with the dilute non-ionic surfactant solution, stir for 20-30 minutes while gradually adding 20-100 grams of deionized water to form a stable and uniform concentrated synergist solution, and leave it to stand for defoaming.
