Abstract

Abstract: Effects of different applicat ions of ZnCl² as base fertilizer on the yield and aroma content of aromatic ricewere studied in pots using a conventional aromatic rice cultivar, Guixiangzhan. The application of 60 mg ZnCl² per 1 kgsoil had the highest effective panicles.Applications of 120 mg and 80mg ZnCl2 per 1 kg soil had the highest spikelets perpanicle and highest seed sett ing rate, respectively. All ZnCl2 applications signif icantly increased the 1 000??grain weight.Yields of 60, 80, 100, and 120 mg ZnCl² per 1 kg soil were significant ly higher than that of CK.Aroma contents in brownrice of 20, 40, 60, 80, 100, 120 and 160 mg ZnCl² per 1 kg soil as base fertilizer were significantly higher than that of CK.Specially, applications of 80, 100 and 120mg ZnCl² per 1 kg soil as base fertilizer had the highest aroma content in brown rice. The optimum applications of aromatic rice were from 80 mg to 120 mg ZnCl2 per 1 kg soil as base fertilizer.
