摘要： 以常规香稻品种桂香占为材料,采用盆栽试验,研究了不同锌肥施用量对香稻产量和糙米香气含量的影响。结果表明,基施氯化锌60 mg/kg土壤处理的有效穗数最多,基施氯化锌120 mg/kg土壤处理的每穗总粒数最多,基施氯化锌80 mg/kg土壤处理的结实率最高,锌肥处理均促进千粒重增加;基施氯化锌60,80,100,120 mg/kg土壤处理的籽粒产量显著高于对照;基施氯化锌20,40,60,80,100,120,160 mg/kg土壤处理的糙米香气含量显著高于对照,其中以基施氯化锌80,100,120 mg/kg土壤处理的糙米香气含量最高;香稻最佳氯化锌基肥施用量为80~120 mg/kg土壤。

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.
