A kind of basal application type special blended fertilizer for peanuts and preparation method thereof

Abstract

The invention relates to a special bulk blending fertilizer for basal application type peanuts and a preparation method thereof. The special bulk blending fertilizer is characterized by being prepared from the following raw materials in percentage by weight: 15.0%-25.0% of urea, 6.0%-10.0% of slow release coating urea, 25.0%-35.0% of diammonium hydrogen phosphate, 20.0%-30.0% of potassium chloride, 12.5%-21.5% of magnesium sulfate, 0.5%-0.8% of zinc sulfate and 0.5%-0.8% of a boric fertilizer. The fertilizer can promote high yield of the peanuts and is simple in preparation process and low in cost.

Description

technical field [0001] The invention relates to a base application type peanut special blend fertilizer and a preparation method thereof. Background technique [0002] Peanut is one of the most important sources of edible oil and protein in my country, with an annual planting area of ​​more than 67 million mu and a total output of more than 15.5 million tons, occupying an important position in my country's edible oil supply. At present, the relatively low benefits of peanut planting in my country have affected the enthusiasm of farmers for planting. Among them, the unreasonable use of fertilizers is one of the important reasons, mainly as follows: 1. my country has a wide range of peanut planting areas, diverse ecological environments, complex soil types, and various varieties of peanuts , Different regions lack targeted special fertilizer products that can meet the needs of high-yield and high-efficiency peanut production; 2. Farmers have unilaterally applied high-concentrat...

At present, the relatively low benefits of peanut planting in my country have affected the enthusiasm of farmers for planting. Among them, the unreasonable use of fertilizers is one of the important reasons, mainly as follows: 1. my country has a wide range of peanut planting areas, diverse ecological environments, complex soil types, and various varieties of peanuts , Different regions lack targeted special fertilizer products that can meet the needs of high-yield and high-efficiency peanut production; 2. Farmers have unilaterally applied high-concentration elemental or compound (mixed) fertilizers for many years, and the supplement of trace elements in the soil is insufficient; 3. Farmers generally use nitrogen fertilizers Excessive application of potassium fertilizer and insufficient application of potassium fertilizer lead to low comprehensive fertilizer utilization efficiency; 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 late stages is insufficient, which easily leads to premature aging, affecting peanut yield and Planting benefit
