Embodiment

[0011] An organic and inorganic compound fertilizer is characterized in that: the method uses fermented organic fertilizer and inorganic fertilizer to mix and granulate; the organic fertilizer is deodorized by fermentation of livestock and poultry manure, rice husk, straw, etc. The inorganic fertilizer is one or more of urea, ammonium phosphate, potassium chloride and potassium sulfate.

[0012] A method for preparing organic and inorganic compound fertilizers as claimed in claim 1, characterized in that: the method comprises the steps of:

[0013] (1) Organic fertilizer raw materials, livestock and poultry manure, rice husk, straw mixed composting fermentation treatment, drying;

[0014] (2) Add inorganic fertilizer urea, ammonium phosphate, potassium chloride, potassium sulfate, etc., mix and stir, heat to 90-100°C, enter the drum granulation, drum drying, ventilation and cooling, and sieve to obtain the finished product.

Abstract

The invention relates to preparation of a fertilizer, in particular to an organic-inorganic compound fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer processing. The method comprises the following steps of: fermenting and deodorizing livestock excrement, rice husk, straw and the like; mixing inorganic fertilizers such as urea, ammonium phosphate, potassium chloride, potassium sulfate and the like; and granulating and drying to obtain a finished product. The compound fertilizer has a reasonable formula and a simple processing technique, contains complete nutrients, can be used for effectively improving soil hardening and the like, and helps to facilitate stable production and high yield of agriculture.

Description

technical field [0001] The invention relates to the preparation of a fertilizer, in particular to an organic and inorganic compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizer processing. Background technique [0002] Organic fertilizers contain various nutrients needed for plant growth. On the one hand, the soil is mineralized to release nutrients, and on the other hand, it is humified to form soil humus. However, the content of nitrogen, phosphorus, and potassium in organic fertilizers is not high, and the fertilizer effect is slow, and the use alone cannot meet the needs of crops. Inorganic fertilizers have high nutrients and fast fertilizer efficiency, which can promote stable and high yields. How to organically combine the two is the subject of research and exploration at present. Contents of the invention [0003] The purpose of the present invention is to provide a kind of organic and inorganic compound fertilizer and...
