Abstract

The invention discloses a preparation device and a preparation method of a hydrophobic slow-release organic-inorganic compound fertilizer, the preparation device of the hydrophobic slow-release organic-inorganic compound fertilizer comprises an activation reaction kettle, a material conveying channel I, a compounding tank, a buffer tank, a spraying granulation dryer and a material conveying channel II; according to the invention, the hydrophobic agent is coated to form a plurality of hydrophobic layer films in the fertilizer particles, so that the pores of the fertilizer particles are blocked, the surface wetting angle of the fertilizer particles is increased, water in soil is not easy to wet the interiors of the fertilizer particles, and water-soluble inorganic nutrients in the fertilizer are not leached; and inorganic nutrients are gradually released from outside to inside only along with gradual decomposition and utilization of organic matters from outside to inside, and the hydrophobic slow-release organic-inorganic compound fertilizer can have multiple nutrient proportions from outside to inside through slurry with multiple nutrient proportions and multi-layer spraying granulation.

Description

technical field

[0001] The invention belongs to the technical field of preparing hydrophobic slow-release organic-inorganic compound fertilizers, in particular to a preparation device and method for hydrophobic slow-release organic-inorganic compound fertilizers. Background technique

[0002] Organic-inorganic compound fertilizer is a compound fertilizer that contains both organic matter and appropriate amount of chemical fertilizers. Organic matter can improve soil physical, chemical and biological properties, improve soil aggregate structure, and improve soil water and fertilizer retention through these biochemical effects. It is an important development direction of the fertilizer industry in the future to improve the utilization rate of soil nutrients.

[0003] The organic matter in the organic-inorganic compound fertilizer has low solubility and slow decomposition speed in the soil, and can only be decomposed by the action of soil microorganisms. There are the followin...
