Abstract

The invention discloses a peanut organic slow-release fertilizer which is prepared as follows: overfiring and grinding iron ore, dolomite, feldspar and powder slag, then adding animal manure, maize straw charcoal powder and water for fungal fermentation; mixing sepiolite, ferrous sulfate, citric acid, manganese sulfate, sodium silicate, ammonium molybdate, urea phosphate and borax; adding rapeseed cake for bacterial fermentation; adding honeycomb coal cinder for mixing, drying and crushing; and adding dicyandiamide powder, polyvinyl alcohol, urea and a slow release agent to obtain the peanut organic slow-release fertilizer. The peanut organic slow-release fertilizer has the advantages of easily obtained raw materials, low cost, and high utilization rate of nutrient elements, can supplement trace elements needed in the growth of peanuts, is strong in slow release capability, and can meet the nutrient demand for the whole growth period of the peanuts.

Description

technical field [0001] The invention relates to the technical field of special fertilizers, in particular to an organic slow-release fertilizer for peanuts. Background technique [0002] Peanut is an important source of edible oil and protein in my country. The annual planting area is more than 70 million mu, and the total output is more than 14 million tons. It occupies the second place in my country's edible oil supply crops. However, the benefits of peanut planting in my country are low, which affects the enthusiasm of farmers for planting. The existing high-concentration compound fertilizers or compound fertilizers contain insufficient trace elements, requiring multiple fertilization, and reducing fertilizer use efficiency. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a peanut organic slow-release fertilizer, which has easy-to-obtain raw materials, low cost, high utiliz...
