| 【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. |
