Embodiment Construction

[0011] Implementation one

[0012] (1) Crush and ferment: Crush the wheat straw to about 100 mesh, mix it with ammonium bicarbonate at a mass ratio of 10:1, add an appropriate amount of water, and ferment in a sealed container for 1 month at an ambient temperature of 10-30°C About; then crush other raw materials to 100 mesh;

[0013] (2) drying: the fermented wheat straw is dried in a drying room to make fermented powder;

[0014] (3) Mixing: Fermentation material powder, phosphate fertilizer after pulverization, urea etc. are by the ratio of 22: 21 by mass, through stirring and mixing, make semi-finished material;

[0015] (4) Granulation: Add 2-6% slow-release agent to the semi-finished material, and use a fertilizer granulator to granulate.

[0016] Implementation two

[0017] (1) Crushing and fermenting: crush the wheat straw to about 99Id, mix it with ammonium bicarbonate in a ratio of 10:1 by mass, add an appropriate amount of water, control the external temperature t...

Abstract

The invention discloses a method for producing a compound fertilizer. The compound fertilizer is prepared from wheatgrass, ammonium hydrogen carbonate, a phosphatic fertilizer, urea and the like which serve as raw materials by processes of crushing, fermenting, mixing, granulating and the like. In the compound fertilizer, a large number of straw resources such as the wheatgrass and the like are utilized fully and effectively, so the compound fertilizer has the capacity of the conventional compound fertilizer and can replenish trace elements such as ferrum, copper, zinc, manganese, molybdenum, boron and the like which are necessary to the growth of plants effectively.

Description

technical field [0001] The invention relates to a production method of compound fertilizer. Background technique [0002] Compound fertilizer is a general term for compound fertilizers and mixed fertilizers, which are processed by chemical and physical methods. The production of compound fertilizer can materialize fertilization technology, improve fertilizer efficiency, reduce the frequency of fertilization, and save the cost of fertilization. The production and application of compound fertilizers has attracted widespread attention from all over the world. Compound fertilizer is the echo of the development of the world's chemical fertilizer industry. The world's consumption has exceeded 1 / 3 of the total consumption of chemical fertilizers, while my country accounts for about 18% of the total domestic consumption of chemical fertilizers. my country's crops are diversified, and the soil has also been overcome by the past. The so-called "correction fertilization" that lacks a ...
