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。
Effects of different applications of ZnCl2 as base fertilizer on the yield and aroma content of aromatic rice were studied in pots using a conventional aromatic rice cultivar,Guixiangzhan.The application of 60 mg ZnCl2 per 1 kg soil had the highest effective panicles.Applications of 120 mg and 80 mg ZnCl2 per 1 kg soil had the highest spikelets per panicle and highest seed setting rate,respectively.All ZnCl2 applications significantly increased the 1 000-grain weight.Yields of 60,80,100,and 120 mg ZnCl2 per 1 kg soil were significantly higher than that of CK.Aroma contents in brown rice 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 120 mg 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.
