摘要
研究了高氮水平下施用硅肥对水稻经济性状的影响。结果表明:高氮水平下施用硅肥可降低水稻株高,增加穗数和千粒重,提高结实率和产量,同时增强水稻的抗倒伏能力和抗病性。其中施用硅肥150 kg/hm2处理的水稻,经济性状表现最好,产量最高。
The effects of applying silicon fertilizer on the economic characters of rice under high nitrogen level were studied. The results showed that applying silicon fertilizer under high nitrogen level could decrease the plant height,increase the spike number, 1 000-grain weight, seed setting rate and yield, and enhance the disease and lodging resistances of rice. The economic characters of rice were the best, and the yield was the highest with the application of 150kg/hm^2 silicon fertilizer.
