Special suspension liquid compound fertilizer for saline-alkali soil and preparation method of special suspension liquid compound fertilizer

Abstract

The invention discloses a special suspension liquid compound fertilizer for saline-alkali soil and a preparation method of the special suspension liquid compound fertilizer. The compound fertilizer comprises the following raw materials in parts by weight: 0.8-7.2 parts of a nitrogen fertilizer, 0.6-1.1 parts of a boric fertilizer, 0.5-0.8 part of EDTA-Zn, 0.5-0.8 part of EDTA-Mn, 2.0-5.0 parts of humic acid powder, 7.0-14.0 parts of a calcium fertilizer 8.0-16.0 parts of a phosphatic fertilizer, 5.0-9.0 parts of a potash fertilizer, 14.0-19.0 parts of an organic matter, 6.0-9.5 parts of a soil conditioner, 0.8-2.0 parts of a microbial agent, 2.0-4.0 parts of a wetting dispersant, 2.0-4.0 parts of an emulsifier, 1.0-3.0 parts of a thickener, 1.5-3.0 parts of an antifreezing agent and 23-30 parts of water. Through reasonable compounding of various nutritional ingredients, especially an efficient synergistic effect among the humic acid, the soil conditioner and the microbial agent, the physical and chemical properties of the soil are well adjusted, re-accumulation of saline matters is avoided, and nutrient elements required for growth and development are provided for crops, thus better growth of roots of the crop is facilitated, the yield and the quality of the crop are improved, and meanwhile, the element deficiency of the crop can be effectively prevented.

Description

Technical field [0001] The invention is the field of fertilizer production technology, which involves an organic matter, humic acid, microbial bacteria, soil conditioning agent, a large amount of medium -sized element fertilizer, especially a salt -alkali -alkali -specific suspended fluid compound fertilizer and their preparation methods.Essence Background technique [0002] Salt and alkali soil is a general term for salt soil and alkali soil, as well as various salt and alkaline soil.The content of soluble salt in the soil reaches a certain degree of soluble salt, which can cause obvious dangers to the growth and development of plants.Alkaline soil refers to the soil where the soil contains a large amount of intensive ions, reaching the degree of the growth and development of plant growth and changes in the nature of the soil.In actual conditions, salt soil and alkali soil often exist together in a mixed manner, collectively referred to as saline and alkali soil.

AI Technical Summary

Problems solved by technology

[0005] At present, most of the fertilizers used in saline-alkali land are ordinary liquid fertilizers, the nutrient content of which is between 15% and 25%, and the nutrient content is relatively low, making it difficult to distribute

Moreover, although ordinary liquid fertilizers can supplement enough nutrients for the soil, they ignore the improvement of the physical and chemical properties of the soil, and it is not easy to release nutrients under favorable environmental conditions.

Therefore, it is difficult for ordinary liquid fertilizers to be popularized in a large area in saline-alkali land.
