STANLEY Agricultural Group Co., Ltd ，Linshu 276700 ，China） Abstract：The hardening mechanism of the urea-based compound fertilizer by tower granulation is described, the special homemade anti-hardening agent ZLY for urea-based compound fertilizer by tower granulation produced based on the hardening mechanism is introduced. The anti-hardening effect of ZLY is verified through laboratory simulation of rapid prototyping and natural stacking test. The results show that ZLY achieves the ideal anti-hardening effect at the amount of 0.25% to the mass of fertilizer ，the loose degree is 97.96% after stockpiling 45 d ，which is better than that of other anti-hardening agent brought from the market.
