Effects of Microbes on Degradation Properties of Polymer Slow Controlled-Release Fertilizer

[Objective] The research aimed to study the effects of microbes on the degradation of the slow controlled-release fertilizer.[Method] A polymer slow controlled-release fertilizer was prepared using urea,formaldehyde,and potassium dihydrogen phosphate as raw materials.Microbes in silt were isolated and cultured,and the high-temperature sterilization of the soil was compared with at the same time.[Result] Compared with the high-temperature sterilization of the soil,on the effect of the bacterial microorganism,the polymer slow controlled-release fertilizer had the faster speed of nutrient release and the higher weightlessness,reached 98% and 88% respectively in 80 days.SEM showed that there were a lot of holes on the surface.[Conclusion] The fertilizer is a kind of biodegradable fertilizer and green fertilizer.
