Special fertilizer for peanuts and preparation method thereof

Abstract

The invention discloses a special fertilizer for peanuts and a preparation method thereof. The special fertilizer is prepared from the following raw materials: pearlite, fermented dry cattle manure, bagasse, straws, urea, borax, ferrous sulfate, copper sulfate, zinc sulfate, ammonium molybdate, potassium sulfate, diammonium hydrogen phosphate, calcium carbonate and EM (Effective Microorganisms). According to the special fertilizer for the peanuts, the raw materials are rich in source and are extensive and readily available, the proportioning ratio is reasonable, the nutrition is balanced and comprehensive, the demands of the peanuts on nutrients can be fully met, and the fertilizer effect is exerted to the maximum. The preparation process is simple and is high in feasibility, the growth ofthe peanuts is rapidly promoted, and the yield and quality of the peanuts are improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanut is an important economic crop in my country. It is rich in fat and protein. It is one of the most important sources of edible oil and protein in my country. The annual planting area is more than 67 million mu and the total output is more than 15.5 million tons. It occupies an important position. At present, the yield of peanut planting in my country is not high, and the potential for increasing yield is great. Scientific and rational fertilization will be an important way to increase yield. [0003] The benefits of peanut planting in my country are low, which affects farmers' enthusiasm for planting. Among them, the unreasonable use of fertilizers is one of the important reasons. The region lacks targeted special fertilizer products that can meet the needs of high-yield and high-effi...

Problems solved by technology

[0003] The benefits of peanut planting in my country are low, which affects farmers' enthusiasm for planting. Among them, the unreasonable use of fertilizers is one of the important reasons. The region lacks targeted special fertilizer products that can meet the needs of high-yield and high-efficiency peanut production; 2. Farmers have applied high-concentration elemental or compound (mixed) fertilizers one-sidedly for many years, and the trace elements in the soil are insufficient; 3. Farmers generally use excessive nitrogen fertilizers and Insufficient potassium fertilizer application and other phenomena, the comprehensive utilization efficiency of fertilizer is low; 4. Excessive nitrogen application in the early stage inhibits the nitrogen fixation potential of peanuts, and the soil's continuous nitrogen supply capacity for peanuts in the middle and later stages is insufficient, which easily leads to premature aging, affecting peanut production and planting benefits
