Embodiment 1

[0008] Organic-inorganic composite fertilizer, which comprises the following raw material components (by weight): 50kg of organic matter powder, 60kg of inorganic chemical fertilizer, 20kg of bentonite, 20kg of water, and 20kg of water. After uniformity, add bentonite in proportion to mix evenly, add a certain proportion of water to mix evenly, put it into an extruder to granulate, and pack it for use.

Embodiment 2

[0010] Organic-inorganic composite fertilizer, which comprises the following raw material components (by weight): organic powder 30kg, inorganic chemical fertilizer 40kg, bentonite 10kg, water 8kg, after the organic material is air-dried, it is processed into fine powder by a pulverizer, and the inorganic chemical fertilizer is mixed according to the above ratio. After uniformity, add bentonite in proportion to mix evenly, add a certain proportion of water to mix evenly, put it into an extruder to granulate, and pack it for use.

Embodiment 3

Abstract

An organic-inorganic compound fertilizer includes: organic matter powder 20-50 wt%, inorganic chemical fertilizer 30-60 wt%, bentonite 5-20 wt%, and water 3-20 wt%. The preparation process includes air-drying organic matter, crushing into fine powder, mixing with certain amount of inorganic chemical fertilizer, adding a certain amount of bentonite, adding water, extruding in an extruder to pelletize, and packaging. The production process has high production efficiency and can effectively treat various wastes of industry and agricultural to reduce environmental pollution.

Description

technical field [0001] The invention relates to the technical field of organic and inorganic compound fertilizers. Background technique [0002] At present, the organic raw materials in the domestic production of organic-inorganic compound fertilizers are mainly industrial organic wastes, crop straws, and livestock and poultry manures decomposed by microorganisms. The role of organic material decomposition is mainly to reduce the carbon-nitrogen ratio in organic materials, but it has the disadvantages of long decomposition period and large floor area. Moreover, the moisture content of organic materials after decomposition is high, and its For the production of compound fertilizer, it needs to be dried again. Therefore, it is not suitable for the needs of industrialized production. Contents of the invention [0003] The invention provides an organic-inorganic compound fertilizer and a preparation method thereof, which can solve the problems in the prior art that the cycle...
