Problems solved by technology

[0005] At present, the research on thermoplastic resin and thermosetting resin-coated controlled-release fertilizers at home and abroad has developed to a relatively high level, and the technology has become increasingly mature. Good, the problem of high production cost has been initially solved, but there is still a lot of room for improvement; there are research reports that using clay minerals, industrial waste solid powder and using liquid binder to wrap fertilizer to make controlled-release fertilizer, this method Although the purpose of reducing production costs has been achieved, the impact resistance and wear resistance of the product are low because no curing agent is used. On the other hand, due to the use of a large amount of clay minerals and industrial waste, the effective nutrients of the controlled-release fertilizer Low content

Embodiment 1

[0017] Weigh 500kg of diammonium phosphate (18-46-0) granular fertilizer, preheat it to 60°C in a disc granulator, and mix 1.12kg of 4,4'-diphenylmethane diisocyanate and 1.38kg of linseed oil evenly Add to the moving fertilizer granules, with the continuous movement of the fertilizer granules, a cohesive liquid layer is formed on the surface, and the weighed 5kg air-dried and pulverized active extract ingredients containing biomass are sprinkled into the fertilizer in the disc granulator Continue heating to keep the temperature at 60-70°C. With the continuous rotation of the granulator, the powder containing active biomass extract ingredients will be evenly wrapped on the surface of the fertilizer, and it will solidify and form a film after about 6 minutes; 500kg of diammonium phosphate fertilizer was repeatedly wrapped twice to obtain a controlled-release fertilizer with a total coating rate of about 4% wt and controlled release for 2 months, which contained active ingredient...

Embodiment 2

[0019] Weigh 1000kg of large particle urea (46-0-0), preheat to 70°C in a drum, mix 3.2kg polymethylene polyphenylisocyanate and 4.8kg linseed oil evenly and add to the moving fertilizer particles, With the continuous movement of fertilizer particles, a bonded liquid layer is formed on the surface, and 50kg of weighed air-dried and pulverized active extracts containing biomass are sprinkled on the fertilizer in the disc granulator, and continue to heat to maintain a temperature of 60~ 70°C, with the continuous rotation of the granulator, the powder containing active biomass extract components is evenly wrapped on the surface of the fertilizer, and can be solidified into a film after about 5 minutes; Repeat the wrapping twice on the top of the fertilizer to obtain a controlled-release fertilizer containing biomass active extraction components with a total coating rate of about 18% wt and a controlled release period of 12 months. After cooling, it is packaged and put into storage...

Abstract

The invention discloses a coated controlled-release fertilizer containing a biomass active extract component, which relates to a coated controlled-release fertilizer and belongs to the technical field of fertilizers and pesticides. The coated controlled-release fertilizer is characterized in that the coated controlled-release fertilizer comprises a fertilizer and a biomass active extract component solid film material. The invention has the following beneficial effects: the controlled-release fertilizer containing the biomass active extract component uses a biomass active substance extracted in the process of biomass gasification as a main component, and the biomass active extract component has a plurality of biological activities and functions; the controlled-release fertilizer can provide comprehensive nutrition for a plant, has bactericidal, sterilizing, inspect-repelling and insecticidal effects and the function of regulating growth of the plant, does not contain chemical pesticides and biological pesticide, is a natural, green and pollution-free preparation, is healthy and safe in usage and leaves no residue.

Description

[0001] technical field [0002] The invention relates to a coated controlled-release fertilizer, which belongs to the technical field of fertilizers and pesticides, in particular to a coated controlled-release fertilizer containing active components extracted from biomass. Background technique [0003] Biomass active organic extracts are obtained through condensation, separation and extraction during biomass gasification, and mainly contain a large amount of active organic components extracted from biomass, including active organic components such as alcohols, phenols, ketones, esters, acids, etc. Organic components, these active organic substances themselves have a certain antibacterial, bactericidal and anthelmintic effects; the active organic extracts of biomass are rich in polyphenols, high in superoxide dismutase activity, and good in oxidation resistance, which can promote The proliferation of useful microorganisms in the soil is beneficial to the growth of roots and...
