Problems solved by technology

[0003] In order to improve the soil quality of saline-alkali soil, the existing improvement method is generally to add various crop fertilizers specially used for saline-alkali soil to the saline-alkali soil, and use humic acid, zeolite, nitrogen, phosphorus and zinc elements in the special fertilizer to improve the salinity. The components of alkaline soil are used for the growth of crops. Although this special fertilizer can improve soil salinity and supplement nutrition for crops to a certain extent, it cannot fundamentally improve the soil quality of saline-alkali soil, and the fertilizer The nutrient elements added are not comprehensive, and cannot provide effective and comprehensive nutrient elements for crops, let alone effectively reduce the pH value of saline-alkali soil

Embodiment 1

[0028] The nitrogen, phosphorus and potassium fertilizers described in this embodiment include urea formaldehyde, potassium sulfate, ammonium sulfate and monoammonium phosphate, and the specific content of each component is: 32.5 parts of humic acid, 7 parts of activated carbon, 15 parts of gypsum, 0.5 part of borax, sulfuric acid 2 parts of zinc, 10 parts of ammonium sulfate, 13 parts of urea formaldehyde, 10 parts of monoammonium phosphate, and 10 parts of potassium sulfate. Among them, urea formaldehyde is mainly used as slow-release nitrogen, which can delay the release rate of nitrogen, reduce nitrogen loss and provide nitrogen fertilizer for plants to continuously absorb and utilize. Ammonium sulfate provides nitrogen nutrients for crops, can use carbon dioxide as the main carbon source to synthesize cell matter, and obtain the energy needed for crop growth by oxidizing external inorganic substances, and can also increase the acidity of the soil to improve the alkalinity ...

Embodiment 2

[0030] The difference between this embodiment and Example 1 is that the components of nitrogen, phosphorus and potassium fertilizers are different. The nitrogen, phosphorus and potassium fertilizers in this embodiment include urea formaldehyde, potassium sulfate and monoammonium phosphate, and the specific content of each component is: each of the fertilizers The parts by weight of the components are: 40 parts of humic acid, 8 parts of activated carbon, 10 parts of gypsum, 1 part of borax, 3 parts of zinc sulfate, 11 parts of monoammonium phosphate, 15 parts of urea formaldehyde, and 12 parts of potassium sulfate. The effect of each component is the same as in Example 1, but the number of components is reduced, which is more convenient for processing.

Embodiment 3

[0032] The difference between this embodiment and the above-mentioned embodiments is that the components of nitrogen, phosphorus and potassium fertilizers are different. The nitrogen, phosphorus and potassium fertilizers in this embodiment include urea formaldehyde, potassium sulfate and diammonium phosphate, and the specific content of each component is: humic acid 37 5 parts, 5 parts of gac, 10 parts of gypsum, 1 part of borax, 2 parts of zinc sulfate, 13 parts of diammonium phosphate, 18 parts of urea formaldehyde, 14 parts of potassium sulfate, the effect of each component in its component and embodiment one is identical, The diammonium phosphate contains 18% nitrogen and 46% phosphorus pentoxide, which increases the effective nutrient elements and can further promote the growth of crops.

[0033] The preparation method of the crop fertilizer of the present invention may further comprise the steps:

[0034] Step 1, taking the components in specified weight parts, and pulve...

Abstract

The invention discloses a crop fertilizer applicable to saline-alkali soil. The crop fertilizer comprises humic acid, active carbon, azophoska, gypsum, borax and zinc sulfate, wherein the humic acid has ion exchange and complexing effects, excessive hydrochloride and sulfate of the saline-alkali soil can be reduced, the adsorption effect of the active carbon also has fertilizer keeping and water retention effects, and the added azophoska, the borax and the zinc sulfate form a comprehensive nutritive crop fertilizer; and the added gypsum per se forms a saline-alkali soil modifying agent, so the crop fertilizer is integrally synthesized to become a saline-alkali soil crop fertilizer. According to the preparation method of the crop fertilizer disclosed by the invention, crop fertilizer finished products are formed through mixing, particle forming, drying and cooling, the process is simple, the related process equipment is little, the production efficiency is favorably improved, and in addition, the investment cost is reduced.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to an agricultural fertilizer suitable for saline-alkali soil and a preparation method of the fertilizer. Background technique [0002] The characteristic of saline-alkali soil is that the soil solution contains sodium carbonate and sodium bicarbonate, and the soil colloid contains exchangeable sodium, so the saline-alkali soil is strongly alkaline, and its pH value can reach more than 9, and the concentration of the soil solution in saline-alkali land is too high , which is greater than the solution concentration of the crop cells, causing the crop cells to lose water and affecting the work of the crop cells. In addition, saline-alkali soil is easy to harden. After hardening, the gas is not easy to be mixed in the soil. The soil is heavy and has poor permeability, which leads to a decrease in the respiration efficiency of the crops. The combination of the two seriously affects the meta...
