Abstract
The invention discloses a preparation method for a slow-release fertilizer. A fertilizer to be coated is preheated to the temperature of 45-55 DEG C in a revolving drum. Ingredients A and B are mixed and sprayed onto the surface of the fertilizer uniformly through a nozzle, and the spraying quantity at each time is about 1% of the total mass of the fertilizer. After the last-time ingredients A and B are reacted fully, the next spraying is carried out and the spraying number is 2-8 times. Then ingredient C is heated, melted and sprayed onto the surface of the ingredients A and B, the spraying quantity is 1.5% of the total mass of the fertilizer and the required product is obtained. The product is advantageous in that, no micromolecular harmful substances are generated in the production process, the coating agents is non-toxic and harmless, and is biodegradable, the processing technology of the slow-release fertilizer is simple and the like.

Slow-release fertilizer also claims Controlled Release Fertilizer, on chemical fertilizer granule surface, wrap the hydrophobic substance that one deck is very thin exactly and make coating fertilizer, moisture can enter the semi-permeable membranes of porous, and the nutrient dissolving is to film external diffusion, constantly supply with crop, fertilizer nutrient release rate is adjusted, according to crop demand, discharged nutrient, reach the running balance of element fertilizer providing intensity and plant physiology demand.
Slow-release fertilizer has following advantage:
1. fertilizer amount reduces, and utilization ratio improves.Slow-release fertilizer fertilizer efficiency is than the length of general not coating more than 30 days, and leaching volatilization loss reduces, and fertilizer amount can reduce 10-20% than conventional fertilizer application, reaches cost-saving object.
2. use conveniently saving of labor's safety.Can coordinate with readily avaiable fertilizer that to make base manure disposable employed, fertilising recruitment reduces by 1/3rd left and right, and uses safety, anti-fertilizer damage.
3. increasing both production and income.Use rear performance fertilizer efficiency surely long, not de-power of later stage, disease-resistant anti-fall, increase production more than 5%.Domestic slow-release fertilizer mainly be take sulphur and is coated as main, and cost is lower, but life-time service can change the acid-basicity of soil.Although Synolac is coated in addition, the coated slow-release fertilizer of urea-formaldehyde resin overcomes the impact on soil acidity or alkalinity, but in production process, mostly use low-volatile solvent based material, product and production environment are caused to certain influence, in In Alkyd Resin Production, can use toluene or dimethylbenzene as thinner, and the main raw material of urea-formaldehyde resin is formaldehyde, no matter be in production process, or the finished product all can have the formaldehyde of certain content to be mixed in urea-formaldehyde resin.
