中文摘要:
      【目的】研究硅肥施用对糯稻抗病性能和产量及经济效益的影响,为我国南方糯稻的合理种植提 供技术支撑。【方法】于 2018 年在江西省景德镇市浮梁县进行田间小区试验,分析硅肥施用与否对糯稻穗颈稻 瘟病和纹枯病发生状况、产量和碾米品质以及经济效益的影响。【结果】与不施硅肥相比,施用硅肥处理的穗 颈稻瘟病株率和病情指数分别下降 80.65% 和 84.23%,纹枯病病株率和病情指数也分别降低 51.93% 和 73.44%, 糯稻产量、千粒重、精米率和整精米率分别比不施硅肥处理增加 19.74%、12.17%、5.42% 和 10.04%。扣除硅肥 等农资投入,进一步计算表明,硅肥处理的效益比不施硅肥增加 23.48%。【结论】在糯稻种植中,增施硅肥是 提高抗病能力和增产增收的主要途径。
英文摘要:
      【Objective】 The objective of this study was to explore the effects of the application of silicon fertilizer on the disease resistance, yield and economic benefit of glutinous rice, which could provide technical support for the reasonable planting of glutinous rice in southern China.【Method】A field trial was conducted in Fuliang County, Jingdezhen City, Jiangxi Province of China in 2018, which included silicon fertilization (+Si) and no silicon fertilization (-Si) treatments. And the occurrence of rice blast and sheath blight and yield, rice quality, and economic benefits of glutinous rice were analyzed. 【Result】 The result showed that: Compared with -Si treatment, the rate and disease index of rice blast disease of +Si treatment were decreased by 80.65% and 84.23%, respectively. In addition, the rate and disease index of rice sheath blight were also reduced by 51.93% and 73.44%, respectively. The grain yield, 1000-grain weight, polished rice rate and whole milled rice rate of +Si treatment were increased by 19.74%, 12.17%, 5.42% and 10.04% respectively compared with those of -Si treatment. Further calculations showed that the benefit of +Si treatment was 23.48% higher than that of -Si treatment, without the investment of agricultural inputs such as silicon fertilizer.【Conclusion】Therefore, in the cultivation of glutinous rice, the increasing application of silicon is one of the main ways to improve disease resistance and increase rice yield and benefits.
