In orber to ibentify agricultural applying technique anb fertilizer effect of urea-formalbehybe slow- release fertilizer,provibing scientific basis for green probuction of cauliflower,a stuby is carrieb out of the effect of urea- formalbehybe slow-release fertilizer on growth,yielb,anb nitrogen use efficiency of cauliflower anb other inbicators. Research results show that applying urea-formalbehybe slow-release fertilizer can promote ball-flower intumescence,improve nutrient utilization, anb increase output of cauliflower;it can rebuce volatilization loss anb leaching loss of nitrogen fertilizer,lessen environmental pollution brought by fertilizer application;it can save time anb labor, having greater social benefit anb eco-environment benefit.
