A kind of garlic sulfur-coated compound fertilizer and preparation method thereof

Abstract

The invention relates to a sulfur-coated compound fertilizer for garlic, which belongs to the technical field of fertilizer preparation and comprises the following raw materials: nitro compound fertilizer, slow-release insecticide, phosphoric acid, urea, potassium magnesium phosphate fertilizer, zinc sulfate, manganese sulfate, molybdenum ammonium phosphate, ferrous sulfate; the invention also discloses the preparation method of the compound fertilizer, heating phosphoric acid and urea at 60-70°C to form urea phosphate molten slurry, adding potassium magnesium phosphate fertilizer, zinc sulfate, manganese sulfate, Ammonium molybdate and ferrous sulfate are stirred and mixed, and sprayed into a granulator for granulation. After granulation, liquid sulfur is sprayed on the surface of the granules through a high-pressure nozzle, and component A is obtained after drying; component A and nitro compound Fertilizer and slow-release insecticide are stirred and mixed to obtain garlic sulfur-coated compound fertilizer, in which the ratio of nitrogen, phosphorus and potassium nutrients is reasonable, and trace elements are added to ensure that garlic can meet the demand without causing fertilizer damage; Compared with ordinary fertilizers, the slow release of nutrients improves the utilization rate of fertilizers and achieves the purpose of weight loss and efficiency enhancement.

Description

A kind of garlic sulfur-coated compound fertilizer and preparation method thereof technical field The invention belongs to the technical field of fertilizer preparation, specifically, relate to a kind of garlic sulfur coating compound fertilizer and preparation method thereof Law. Background technique [0002] Garlic has been regarded as a natural fungicide since ancient times, and is called "natural antibiotic". Garlic can be eaten raw, and its nutritional value is relatively high High, the physiological effect is obvious. It can also be further processed into a series of products, such as health food, cosmetics, feed additives, etc. [0003] The current garlic planting faces many problems, such as soil compaction, lack of nutrients, fertilizer damage, heavy cropping, serious diseases and insect pests, etc. in The problem of pests and diseases is more deadly. Leaf blight is prone to occur in garlic planting. Leaf blight mainly affects garlic leaves, and the disease s...

Problems solved by technology

The emergence of these problems not only affects the yield and quality of garlic, but also poses a threat to soil health

The growth period of garlic is long, and it is inconvenient to topdress in the later stage, and the labor cost of the whole growth process is relatively high
