我公司研发了一种工艺简单、生产成本低、耗能低、无结块、无“三废”污染、可形成规模化生产的喷涂硫黄树脂型缓控释肥的制造方法。采用喷涂硫黄树脂制成的缓控释肥能够达到养分缓控释的目的,且能彻底解决传统包膜缓控释肥存在的对土壤二次污染的问题。现介绍如下。 Our company has developed a manufacturing method of spraying sulfur-containing resin controlled release fertilizer with the advantages of simple process, low production cost, low energy consumption, no agglomeration and no “three wastes” pollution. The controlled-release fertilizer made of spraying sulfur resin can achieve the purpose of controlled release of nutrients and can completely solve the problem of secondary pollution of soil with traditional coated slow release fertilizer. Now introduced as follows.
