| 【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】本研究于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】结果表明：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了80.65%和84.23%，其纹枯病病株率和病情指数也分别降低了51.93%和73.44%。同时，施用硅肥处理的产量、千粒重、精米率和整精米率分别比不施硅肥处理增加了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，硅肥处理的效益分别比不施硅肥处理增加了23.48%。【结论】因此，在糯稻种植中，硅肥是提高抗病能力和增产增收的主要途径之一。 |

| 【Objective】The objective of this study was to explore the effects of silicon fertilizer application on the disease resistance, yield and economic benefit of glutinous rice. Meanwhile, it could provide technical support for the reasonable planting of glutinous rice in southern China. 【Method】A field experiment was conducted in Fuliang County, Jingdezhen City, Jiangxi Province of China in 2018, which included silicon fertilization (+Si) and no silicon fertilization (-Si) treatments. Then, the changes of rice blast and sheath blight, yield, rice quality, and economic benefits were analyzed. 【Result】The result was shown that: compared with -Si treatment, the rate and disease index of rice blast disease in +Si treatment were decreased by 80.65% and 84.23%, respectively, in addition, the rate and disease index of rice sheath blight disease were also reduced by 51.93% and 73.44%, respectively. At the same time, the grain yield, 1000-grain weight, polished rice rate and whole milled rice rate of +Si treatment were increased than -Si treatment by 19.74%, 12.17%, 5.42% and 10.04%, respectively. Further calculations showed that the benefits of +Si treatment was increased by 23.48%, compared with -Si treatment, without the investment of agricultural inputs such as silicon fertilizer.【Conclusion】Therefore, in the cultivation of glutinous rice, silicon fertilization is one of the main patterns to improve disease resistance, as well as increase rice yield and benefits. |
