Problems solved by technology

Among them, in the application process of foliar spraying, since the surface layer of the leaves of many plants is often covered with a hydrophobic waxy layer, and the hydrophobic waxy layer has a certain surface tension, it is not easy to be wetted by the foliar fertilizer. Thereby reducing the utilization rate of water-soluble fertilizer, resulting in a waste of resources
The main way to reduce the surface tension of water-soluble fertilizers is to add surfactants to them, but conventional surfactants cannot be biodegraded or are toxic, which is not conducive to the construction of green ecological agriculture. However, the current green and pollution-free methods to improve leaf surface fertilizer There are not many relevant studies on wet performance, and the present invention has carried out related research experiments

Embodiment 1

[0026] The raw materials of the macroelement water-soluble fertilizer with enhanced wettability include NPK nutrients, trace element nutrients, modified humic acid reagents, silicon-based surfactants, chelating agents, defoamers and water.

[0027] The preparation method of the macroelement water-soluble fertilizer for enhancing wettability is as follows:

[0028] Take 900ml of water and heat it to 40°C, add 10g of chelating agent EDTA and 10g of β-cyclodextrin and stir to dissolve. After the dissolution is complete, stir and add 560g of urea, 271g of potassium dihydrogen phosphate, 14g of potassium nitrate and 18g of borax one by one in proportion, and keep at 40°C After stirring for 30 minutes, add 20g of modified humic acid reagent and 5g of Silwet 608 surfactant. Dissolving EDTA and β-cyclodextrin first can ensure its chelation with divalent metal ions such as calcium and magnesium in water, and avoid divalent metals such as calcium and magnesium in water. Ions form precip...

Embodiment 4、6 to 10

[0031] Embodiments 4, 6 to 10 were weighed in turn according to the ratio of the raw materials in the following table 1, and according to the method recorded in embodiment 1, the macroelement water-soluble fertilizer IV was made respectively with different modified humic acid reagents, surfactants and chelating agents , Ⅵ~Ⅹ; In addition, macroelement water-soluble fertilizers Ⅱ, Ⅲ and Ⅴ were prepared according to the same method as three control groups.

[0032] Table 1 Macroelement water-soluble fertilizers with different raw materials and ratios

[0033]

[0034] The difference between macroelement water-soluble fertilizers II to X and macroelement water-soluble fertilizer I is only: changing the ratio of NPK, the amount of modified humic acid reagent, the type and amount of surfactant, the type and amount of chelating agent, and sequentially acting on the The proportions are displayed, see Table 1 above for details.

Embodiment 11

[0057] The raw materials of the macroelement water-soluble fertilizer with enhanced wettability include NPK nutrients, trace element nutrients, modified humic acid reagents, silicon-based surfactants, chelating agents, defoamers and water.

[0058] The preparation method of the macroelement water-soluble fertilizer for enhancing wettability is as follows:

[0059] Take 900ml of water and heat it to 30°C, add 25g of chelating agent EDTA and 25g of β-cyclodextrin and stir to dissolve. After the dissolution is complete, stir and add 560g of urea, 271g of potassium dihydrogen phosphate, 14g of potassium nitrate, 10g of borax, and sulfuric acid monohydrate one by one in proportion 15g of manganese, 5g of zinc sulfate monohydrate, 15g of zinc sulfate heptahydrate, keep stirring at 30°C for 60min, then add 10g of modified humic acid reagent and 5g of Silwet608 surfactant, first dissolve EDTA and β-cyclodextrin to ensure its compatibility with calcium in water Magnesium and other diva...

Abstract

The invention provides a preparation method of a large amount of elemental water-soluble fertilizer with enhanced wetting performance, which comprises the following steps: taking 900 parts of water in the raw material and heating it to 30-40°C, adding 20-60 parts of chelating agent and stirring to dissolve, and waiting to be dissolved Completely, add 500-600 parts of NPK nutrients and 2-30 parts of trace elements one by one according to the above ratio, after stirring, add 10-50 parts of humic acid salt and 5-10 parts of silicon-based surfactant, continue stirring and then add 0.3-0.7 parts of defoamer, after the foam is eliminated and the remaining 100 parts of water is supplemented, continue stirring for 15-30 minutes and then sub-package. The sub-package equipment is equipped with a filter device to filter out insoluble matter. The present invention also provides a macroelement water-soluble fertilizer with enhanced wetting performance, which is obtained by adopting the above preparation method of the macroelement water-soluble fertilizer with enhanced wetting performance. It has the characteristics of low cost, simple use, good wetting effect and environmental friendliness.

Description

technical field [0001] The invention relates to a water-soluble fertilizer with a large amount of elements that enhances wetting performance. [0002] The invention also relates to a method for preparing a water-soluble fertilizer with a large number of elements that enhances wetting performance. Background technique [0003] Although water-soluble fertilizer has just started in China, people in the industry are generally optimistic about its prospects. There are more than 10,000 products registered in the Ministry of Agriculture. The future is vast and bright. my country is one of the countries with poor freshwater resources in the world. The seasonality of agriculture, uneven distribution of industries, and regional water shortages are prominent. As a new type of environmentally friendly fertilizer, water-soluble fertilizers are easy to use, can be sprayed, flushed, and can be used in combination with drip irrigation, which has obvious advantages in improving fertilizer ...
