Embodiment 1

[0040] Add 20.3 kg of polysuccinimide with a molecular weight greater than 5000 to 54.1 kg of water at room temperature, add 18.0 kg of solid potassium hydroxide with a purity greater than 90% while stirring, and control the reaction temperature at about 80°C during the process until the polysuccinimide All imines are dissolved (about 3-4 hours), and then maintain the reaction temperature and add 7.6 kg of citric acid monohydrate to adjust the pH value to 7-8, and obtain 100 kg of brownish-red transparent solution after filtration. The present invention is called "Potassium polypeptide chelate", (the following examples are the same), the active ingredient content is 43%, calculated as potassium salt, the weight ratio of potassium polyaspartate: potassium citrate is 2.9:1.

Embodiment 2

[0042] Add 19 kilograms of polysuccinimide with a molecular weight greater than 5000 to 47 kilograms of water at room temperature, add 24.7 kilograms of solid potassium hydroxide with a purity greater than 90% while stirring, and control the reaction temperature at about 75°C-80°C during the process until After the polysuccinimide is completely dissolved, then maintain the reaction temperature and add 14.4 kg of citric acid monohydrate to adjust the pH value to 7-8, and obtain 100 kg of brownish-red transparent polypeptide chelated potassium solution through filtration. The content of the active ingredient is 53%, calculated as potassium salt, and the weight ratio of potassium polyaspartate: potassium citrate is 1.5:1.

Embodiment 3

[0044] Add 14 kg of polysuccinimide with a molecular weight greater than 5000 to 50 kg of water at room temperature, add 11.6 kg of solid potassium hydroxide with a purity greater than 90% while stirring, and control the reaction temperature at about 85°C during the process until the polysuccinimide After the imine is completely dissolved (about 3-4 hours), then maintain the reaction temperature and add 4 kg of tartaric acid and 20.4 kg of water. After the tartaric acid is completely dissolved, the pH value is 7-8, and the brown-red transparent Polypeptide chelated potassium solution, wherein the active ingredient content is 28%, calculated as potassium salt, and the weight ratio of potassium polyaspartate: potassium tartrate is 3.6:1.

Abstract

The invention provides a novel product of plant nutrient sorbefacient which takes the reaction products of succinimide, organic acid, potassium hydroxide as the aqueous solution of active components, and the aqueous solution has 25-60% of active components with the pH value ranging from 7 to 8; the organic acid can be caused to have complexation with metallic ion to form dicarboxylic acid or tribasic carboxylic acid of soluble metal complex. The invention also provides a method for preparing the plant nutrient sorbefacient and the application of the method in the agricultural industry. The plant nutrient sorbefacient can chelate nitrogen, phosphorus, potassium and micronutrient elements which are needed by growing plant, and convey the nutrient elements to the surrounding of plant root system, thereby promoting the plant to absorb the nutrient, increasing the utilization rate of fertilizer and crop yield, and improving the quality of crops. The invention also provides multiple application modes of the plant nutrient sorbefacient in the agricultural industry on the basis of agricultural productive practice, so as to have flexible and wide application scope.

Description

technical field [0001] The invention relates to the field of agricultural technology, and in particular provides a novel plant nutrient absorption accelerator and a production method thereof. The invention also proposes the application of the plant nutrient absorption accelerator in agricultural production. Background technique [0002] In traditional agricultural production, in order to promote crop growth and increase crop yield, the commonly used method is to apply various fertilizers, especially artificially synthesized chemical fertilizers, such as urea, diammonium phosphate, and compound fertilizers. According to the theory of plant nutrition, the demand of plants for various nutrients (mainly nitrogen, phosphorus, potassium and other macroelements) is in a certain proportion, which is affected by various complex factors such as crop varieties, soil fertility, climatic conditions, and planting methods. The determination of factors is difficult to be accurately grasped ...
