preparation example Construction

[0038] In order to realize the organic combination of plant immunity inducer and controlled release fertilizer, a preparation method of plant immunity inducer type controlled release fertilizer is provided in one embodiment of the present invention, comprising the following steps:

[0039](1) take the plant immune inducer as the core material, and the plant immune inducer is selected from one or more of betaine, brassinolide, humic acid and DA-6; the core material is dissolved in Prepare a uniform solution with water (the concentration of the core material in the uniform solution is 100-400g / L); then add it to the wall material solution, and the weight ratio of the core material to the wall material solution is 1: (2-5); then add Negatively charged colloid, the weight ratio of negatively charged colloid and positively charged wall material solution is 1.5:1; obtain emulsion; under vacuum conditions, adjust the pH value of the emulsion to 4.0-6.5, and precipitate microcapsules ...

Embodiment 1

[0058] Weigh 20 kg of urea and place it in the drum, turn on the switch to preheat the core until the temperature is constant at 80°C. Take by weighing plant immune inducer betaine 400g, be dissolved in water and make uniform solution, add the mixed solution of shellac, gelatin, water and β-cyclodextrin of 1200g (in the mixed solution, β-cyclodextrin and shellac -The weight ratio of gelatin-water mixture is 1:2.6, in the shellac-gelatin-water mixture, the weight ratio of shellac, gelatin and water is 0.6:0.6:12); Then add 1800g negatively charged colloid Carrageenan to obtain an emulsion; under vacuum conditions, adjust the pH of the emulsion to 4.0-6.5 to precipitate microcapsules, then adjust the pH of the emulsion to 6.0-7.0, add 18g of curing agent diglycidyl phenyl ether, and solidify After the microcapsules are post-treated, the microcapsules are obtained and mixed with urea evenly.

Embodiment 2

[0064] Weigh 20 kg of diammonium phosphate and place it in the drum, turn on the switch to preheat the core until the temperature is constant at 80°C. Weigh 400g of plant immune inducer humic acid, dissolve it in water to obtain a uniform solution, add 1200g of ε-polylysine-vitamin E succinate amide complex solution, and then add 1800g of negatively charged colloidal gum arabic , to obtain an emulsion; under vacuum conditions, adjust the pH value of the emulsion to 4.0-6.5 to precipitate microcapsules, then adjust the pH value of the emulsion to 6.0-7.0, add 18g of curing agent laccase, and solidify the microcapsules. Processed to obtain microcapsules and mixed with urea evenly.

[0065] Weigh 39.2g of paraffin, 0.4g of hydroxyethylidene diphosphonic acid, and 0.4g of aminotrimethylenephosphonic acid, and place them in a heating kettle to melt at a constant temperature to 85°C to make a surface modifier; weigh 2000g of sulfur, and place them in a heating kettle The medium mel...

Abstract

The invention discloses a salinity control, alkali reduction and soil improvement mode of coastal saline-alkali soil based on advantage combination of a controlled release fertilizer, a plant immunityresistance inducer and an organic fertilizer. The mode comprises the following steps: combining the plant immunity resistance inducer and the controlled release fertilizer to prepare a plant immunityresistance induction controlled release fertilizer, and performing dislocation application on the plant immunity resistance induction controlled release fertilizer and the organic fertilizer: applying the plant immunity resistance induction controlled release fertilizer at 15-20cm depth of the soil, and the organic fertilizer at 40-50cm depth of the soil. According to the mode, the plant immunityresistance induction controlled release fertilizer and the organic fertilizer are subjected to dislocation application; salinity control from the source can be achieved; salinity superposition damageof crops in a seedling stage is avoided; balancing of cell osmotic pressure of the crops in the saline-alkali soil is kept; downward leaching of base ions due to rainfall irrigation is accelerated; aphysical structure of the soil is improved; an organic content of the soil is increased; and sustainable development of agriculture is promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a coastal saline-alkali soil-controlling salt-reducing-alkali-reducing soil improvement mode based on the superior compatibility of controlled-release fertilizer-plant immune inducer-organic fertilizer. Background technique [0002] Soil salinization is a worldwide soil degradation problem, which not only causes resource destruction, but also brings harm to the environment and economic development. According to the second national soil census, the area of ​​saline-alkali land in my country is as high as 100 million hectares. With the growth of population, economic development and the urgent need to improve the ecological environment, saline-alkali soil resources and salt-tolerant plant resources have become increasingly important. Therefore, planting crops on saline-alkali land is a good way to prevent the continuous deterioration of saline-alkali soil and facilitat...
