Saline-alkali soil repairing novel fertilizer produced by taking high-silicon iron tailings as raw materials

Abstract

The invention discloses a saline-alkali soil repairing novel fertilizer produced by taking high-silicon iron tailings as raw materials.The fertilizer is prepared by stirring and mixing, by weight, 60-70 parts of the high-silicon iron tailings, 2-8 parts of calcium sulfate, 1-6 parts of zinc sulfate, 1-6 parts of plant ash, 5-12 parts of ammonuim humate, 3-8 parts of potassium humate, 1-6 parts of calcium superphosphate, 5-12 parts of bran, 1-6 parts of ammonium molybdate, 3-8 parts of ferric citrate, 3-8 parts of magnesium sulfate heptahydrate, 2-7 parts of monopotassium phosphate, 1-6 parts of potassium chloride, 14-20 parts of fermented chicken manure, 12-18 parts of fermented sheep manure and 10-15 parts of oyster shell powder.According to the saline-alkali soil repairing novel fertilizer produced by taking the high-silicon iron tailings as the raw materials, the soil fertility can be improved, and the ventilation, water seepage, fertilizer conservation and water conservation capacities of saline-alkali soil can be enhanced.

Description

technical field [0001] The invention relates to a new saline-alkali soil restoration fertilizer produced by using high-silicon iron tailings as raw materials. Background technique [0002] Saline-alkali land can be divided into light-saline-alkali land, moderate-saline-alkali land and heavy-saline-alkali land. The main feature of saline-alkali land is that it contains more water-soluble salt or alkaline substances. Due to the high salinity and high alkalinity, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface, poor ventilation and water permeability, and serious plant wilting. , poisoning and rotten root death, so the saline-alkali soil must be improved in order to better grow agricultural plants. However, the existing fertilizers for repairing saline-alkali soil are difficult to effectively reduce soil pH and soil salinity, improve the physical and chemical shape of...

Problems solved by technology

[0003] In addition, some of the existing cultivated land belongs to saline-alkali soil, which cannot grow agricultural plants, or due to the high salt content of the soil, it lacks the necessary elements needed for plant growth, which leads to problems in the yield and safety of crops. Difficult to solve
