Abstract
This paper investigated effects of polymer/sulfur coated urea on number of tillering,proportion of chlorophyll,number of ears of grain,thousand-grain weight,yield,grain protein content and fertilizer use efficiency by field experiment.The results showed that comparison to normal urea,polymer/sulfur coated urea which was used as base fertilizer with a release period of four months could achieve same effects on number of tillering,number of grain ears and wheat yield with 20% and 40% less use level,while thousand-grain weight,grain protein yield and fertilizer use efficiency significantly increased.The results also showed that using polymer/sulfur coated urea as base fertilizer once had better outcome than using it as base and additional dressing fertilizer separately.
