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.

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 belongs to the technical field of fertilizer production, and in particular relates to a fertilizer containing organic matter, humic acid, microbial strains, soil conditioner, a large amount of and medium and trace elements applied to crops, especially a suspension liquid compound fertilizer special for saline-alkali land and its preparation method . Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. In actual conditions, saline soil and alkaline soil often coexist in a mi...
