Abstract

The invention relates to the technical field of fertilizers for crops and in particular relates to a special double-membrane inorganic fertilizer for peanuts. The inorganic fertilizer is characterized in that inner raw materials include urea, ferrous sulfate and single superphosphate; coating materials include gelatin, sulfur and sodium silicate; and outer raw materials include urea, diammonium phosphate, potassium sulfate, zinc sulfate and attapulgite clay powder. A preparation method comprises the following steps of: grinding the inner raw materials, mixing the powder uniformly, granulating the mixture and drying the granules to prepare an inner coated fertilizer; and grinding the outer raw materials, mixing the powder uniformly, adding the inner coated fertilizer for granulation and drying the granules, thus obtaining the inorganic fertilizer. The inorganic fertilizer has the beneficial effects that by adopting the double-layer coated fertilizer, the nutritional requirements of peanuts at different development stages are met through one-time fertilization; the attapulgite clay powder is adopted as an instant fertilizer binding agent and contains rich trace elements, thus enriching the nutritional ingredients of soil; and the inorganic fertilizer is commonly used as the raw material in production, does not pollute the environment and crops, simultaneously is reasonable in formula, is nutritionally balanced, has better effects and can improve the fertilization utilization rate obviously and improve the peanut yield and quality.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a special double-film inorganic fertilizer for peanuts. Background technique [0002] Special fertilizer is an important means and way to improve crop yield and fertilizer utilization efficiency, and at the same time has the advantages of convenient application, strong pertinence, high yield, and good benefit. However, peanuts have different demands on the types and amounts of fertilizers in different growth stages. The current special fertilizers for peanuts are rarely suitable for the growth characteristics of peanuts, and the pertinence is not strong. One-time application cannot well meet the needs of specific fertilizers in different development stages. , in the seedling stage, the development of organisms requires higher nitrogen, phosphorus, and potassium fertilizers, while the later pod development requires higher calcium elements. Insufficient calcium can easil...
