Long-acting environment-friendly compound fertilizer and preparation method thereof

Abstract

The invention discloses long-acting environment-friendly compound fertilizer and a preparation method thereof, and relates to the field of compound fertilizer. The long-acting environment-friendly compound fertilizer is prepared from the following raw materials in parts by weight: 15-20 parts of decomposed coal, 3-8 parts of expired food, 5-10 parts of ammonium dihydrogen phosphate, 3-8 parts of potassium fulvic acid, 8-15 parts of urea, 2-5 parts of sodium metasilicate, 20-25 parts of attapulgite, 4-9 parts of montmorillonite powder, 4-9 parts of polyacrylamide, 5-10 parts of furfural residue, 25-30 parts of animal waste, 15-20 parts of rice hull powder, 5-10 parts of tea seed cake, 5-10 parts of traditional Chinese medicine residue, 0.8-1.6 parts of microelements, 2-5 parts of high-temperature rapid rotting agent, 2-5 parts of eucalyptus oil and 0.8-1.6 parts of silane coupling agent. The compound fertilizer contains rich nutrient elements, the raw material ingredients have the effects of enhancing coordination, promoting crops to grow rapidly, improving the crop production quality, and meanwhile, softening soil and improving the soil physical and chemical properties.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a long-acting environment-friendly compound fertilizer and a preparation method thereof. Background technique [0002] Due to the long-term application of a large amount of inorganic fertilizers, the lack of trace elements in the soil, especially in areas with relatively good economic conditions, the application of a large amount of high-concentration chemical fertilizers, compound fertilizers, and potassium fertilizers has caused serious soil enrichment of nutrients and serious loss of trace elements. The overall quality of the soil is declining, and organic fertilizer resources must be utilized in order to fertilize the soil. Organic fertilizers are rich in various trace elements, which can well make up for the shortage of chemical fertilizers. The basic path of scientific fertilization is to use organic fertilizers and inorganic fertilizers together to improve the utilizat...

Problems solved by technology

The main principle is that due to its water retention performance, it can prevent the water in the soil from evaporating and take away heat to achieve heat preservation. At the same time, corncobs are organic matter, which can achieve the purpose of water retention and heat preservation, but the weathered coal and water-absorbing resins still have the ability to retain fertilizer and water. Poor, not conducive to the full absorption of nutrients in fertilizers
