Soil conditioning fertilizer and preparation method thereof

Abstract

The invention discloses a soil conditioning fertilizer which is prepared from the following raw materials in parts by weight: 60-65 parts of bran, 20-23 parts of corn flour, 20-23 parts of rice bran, 10-12 parts of meerschaum powder, 12-15 parts of urea, 12-14 parts of ammonium nitrate, 9-11 parts of potassium sulfate, 5-7 parts of potassium pyrophosphate, 3-5 parts of potassium chloride, 1-2 parts of sodium selenite, 2-3 parts of zinc sulfate, 3-4 parts of effective microorganism, 4-6 parts of coating agent and a right amount of water. The soil conditioning fertilizer implements organic combination of organic raw materials, secondary and minor elements and quick-acting inorganic fertilizers, has the advantages of reasonable formula, balanced nutrients, high safety and no pollution, completely satisfies the demands of plants for nutrients, and has the function of conditioning the soil characteristics. The prepared fertilizer has wide application range and abundant nutrition, is convenient to use, can effectively enhance the yield and quality of the plants, enhances the disease resistance, insect resistance and lodging resistance of the plants, and has the effects of enhancing the fertilizer utilization ratio, reducing the fertilizer loss and improving the soil fertility.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a soil conditioning fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. At present, the compound fertilizers produced in our country are mainly composed of nitrogen, phosphorus, potassium and other chemical fertilizers. The disadvantage is that after long-term use, it will not only aggravate the pests and diseases of crops, but also cause weeds to grow wildly and cause serious environmental pollution. , make the soil ecological imbalance of cultivated crops, cause soil compaction and other phenomena, form a vicious cycle of agriculture, and restrict the sustainable development of my country's modern agricultural industry. Therefore, although t...

Problems solved by technology

At present, the compound fertilizers produced in our country are mainly composed of nitrogen, phosphorus, potassium and other chemical fertilizers. The disadvantage is that after long-term use, it will not only aggravate the pests and diseases of crops, but also cause weeds to grow wildly and cause serious environmental pollution. , make the soil ecological imbalance of cultivated crops, cause soil compaction and other phenomena, form a vicious cycle of agriculture, and restrict the sustainable development of my country's modern agricultural industry

Therefore, although the fertilizer produced by using domestic fertilizer is rich in organic matter, its nutrient content is low, which cannot meet the overall demand for nutrients for crop growth, and the effect is slow and insignificant. In addition, livestock and poultry manure contains a large amount of harmful substances, which cannot guarantee the safety of agricultural products.
