Embodiment Construction

[0015] An organic-inorganic blended fertilizer for peanuts, wherein the nitrogen content is 12wt%, the phosphorus content is 15wt%, the potassium content is 8wt%, and the organic matter content is 15.9wt%. The formula is shown in the following table:

[0016]

[0017] The preparation method is as follows:

[0018] Calculate the amount of raw materials for inorganic fertilizer and organic fertilizer according to the formula in the above table, and input the raw materials into the mixer and mix them evenly;

[0019] The raw material after mixing is input in the granulator again, adds sulfuric acid as binding agent, and the consumption of sulfuric acid is calculated by adding 50 kilograms of 98%wt vitriol oil for every ton of blended fertilizer;

[0020] Finally, powdering agent equivalent to 2-4wt% of the blended fertilizer is added, and after uniform mixing, the organic-inorganic blended fertilizer for peanuts is obtained.

[0021] When the blended fertilizer is applied to ...

Abstract

The invention discloses a method for preparing an organic and inorganic blended fertilizer. The method comprises the steps of: mixing, granulating and the like. According to the method, a potassium fulvate organic fertilizer and an inorganic fertilizer are adopted to prepare the organic and inorganic blended fertilizer, and the preparation method is simple. As the inorganic fertilizer is added to the blended fertilizer, the yield of crops is increased, the quality of agricultural products is improved, and the soil is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to an agricultural compound fertilizer, in particular to a preparation method of an organic-inorganic blend fertilizer. Background technique [0002] At present, in order to promote the rapid growth of crops, fertilizers play an important role in the development of agriculture. However, the use of a large amount of fertilizers, especially the long-term single application of inorganic fertilizers, and the serious shortage of organic fertilizers lead to insufficient supplementation of organic matter in the soil, low soil organic matter content, and poor structure, which affects the activity of microorganisms, thereby affecting the structure of soil aggregates formation, resulting in excessive acidity of the soil. Due to soil acidification, the micro-ecological environment of the soil has been changed, and harmful microorganisms multiply in large numbers under acidic conditions, whi...
