Embodiment 1

[0025] Weigh 5kg of copper sulfate pentahydrate (1); slowly add it to 6.5L of ammonia water with a concentration of 25%, stir continuously to dissolve it completely, and form a copper coordination complex solution, the reaction time is 20-30min (2); Then add 10L of 5mol / L sodium hydroxide solution in the form of spray droplets for 70-90 minutes, so that the average particle size of the generated copper hydroxide colloid is less than 5 μm (3); then wash the hydroxide with tap water Copper colloidal suspension 3-4 times to make the pH value reach 7.5±0.5, and remove the supernatant by standing or centrifuging to obtain copper hydroxide colloidal suspension (4); dry naturally or in an oven at a temperature lower than 45°C Dry in medium to obtain copper hydroxide colloidal powder (5); take copper hydroxide colloidal powder 300g, add compound amino acid 160g wherein, add dispersant D-425 (alkyl naphthalene sulfonic acid condensation polymer sodium salt) 15g, dispersant SPR (mixture...

Embodiment 2

[0028]Weigh 5kg of copper sulfate pentahydrate (1); slowly add it to 6.5L of ammonia water with a concentration of 25%, stir continuously to dissolve it completely, and form a copper coordination complex solution, the reaction time is 20-30min (2); Then add 10L of 5mol / L sodium hydroxide solution in the form of spray droplets for 70-90 minutes, so that the average particle size of the generated copper hydroxide colloid is less than 5 μm (3); then wash the hydroxide with tap water Copper colloidal suspension 3-4 times to make the pH value reach 7.5±0.5, and remove the supernatant by standing or centrifuging to obtain copper hydroxide colloidal suspension (4); dry naturally or in an oven at a temperature lower than 45°C Dry in medium to obtain copper hydroxide colloidal powder (5); take copper hydroxide colloidal powder 300g, add compound amino acid 160g wherein, add dispersant D-425 (alkyl naphthalene sulfonic acid condensation polymer sodium salt) 15g, dispersant SPR (mixture ...

Embodiment 3

[0031] The addition process is the same as in Example 1, but there are differences in the amino acids added. Such as: add glutamic acid 160g, other processes are with example 1.

[0032] In the obtained suspension concentrate: by dry basis weight, Cu%==39.18%. The suspension pH of this suspension product is 7.0-8.0 when the spraying concentration is 1:500-1000 after adding water.

Abstract

The invention relates to a copper-based nutrition protective agent containing amino acids and a preparation method thereof. According to the copper-based nutrition protective agent containing the amino acids disclosed by the invention, as based on the copper-based nutrition protective agent, amino acids in different types or compound amino acids are added, the copper-based nutrition protective agent containing the amino acids can provide nitrogen elements to plants in a mode of amino acid nitrogen and is easy to be absorbed by the plants after being sprayed, so that the copper-based nutrition protective agent containing the amino acids has the nutrition function while carrying out sterilization, is capable of promoting growth and development of crops, improving the stress resistance and the quality of the crops and increasing the yield of the crops. The copper-based nutrition protective agent containing the amino acids is high in content of the effective components, good in suspension property, strong in adhesion and large in uniformly on the surfaces of the plants and durable in pesticide effect and is capable of resisting rainwash, reducing spraying times and remarkably increasing economical, social and ecological benefits.

Description

(1) Technical field [0001] The invention relates to a copper-based nutritional protection agent containing amino acid and a preparation method thereof, belonging to plant nutrition and plant protection agents. (2) Background technology [0002] Amino acids are the main organic nitrogen compounds in the soil, accounting for 15%-60% of the total nitrogen in the soil. Plants can absorb and utilize amino acids, and the effects of amino acids on plants vary with different amino acids and plant species. Amino acids can directly enter the plant and be directly absorbed by celery, ryegrass, wheat, etc., improving the yield and quality of some crops. At present, there are amino acid fungicides, insecticides, herbicides, plant growth regulators and other series of products. However, there are few reports on the application of amino acids in copper-based nutritional protection agents, and experimental research is needed to provide theoretical basis and technical support for the produ...
