摘  要：
本研究为了探索不同种类及不同用量硅肥对皖南山区稻田水稻产量的影响以及高效硅肥积累水稻品种的筛选。根据土壤缺硅特性(有效硅含量为5.68±0.84 mg/kg),设计了不同硅肥种类及用量的盆栽试验和不同水稻品种硅敏感性的大田试验。盆栽结果表明,不同硅肥种类及用量均可以显著增加水稻产量,其中150 kg/hm~2水溶性硅肥和钢渣硅肥处理比对照的水稻产量增产效果最为明显,分别多出64.53%和23.49%,随着硅肥的用量增加并没有显著增加各硅肥处理水稻的产量;大田试验结果也表明,钢渣硅肥施用对6个水稻品种的产量均有显著增加,其中‘苏秀867’对硅肥最为敏感,施硅肥处理产量比不施硅肥的处理产量增加40.77%,为硅素高效吸收积累水稻品种。故对皖南山区稻田来说,适量的硅肥利用以及高吸收硅的水稻品种选择,可以有效地提高稻季作物产量,增加经济效益。

摘  要：
The aims of this study were to explore the effect of different kinds and amounts of silicon fertilizerson rice yield in the mountainous area of southern Anhui Province and select rice cultivars with high siliconfertilizer accumulation. According to the silicon deficiency properties(available silicon content was 5.68 ±0.84 mg/kg), a pot experiment with different kinds and amounts of silicon fertilizers and a field experiment onrice cultivars with different silicon sensitivity were designed. The pot experiment results showed that differentkinds or amounts of silicon fertilizers could significantly increase rice yield, of which, treatments of 150 kg/hm2 water soluble silicon and slag silicon exerted more significant effect on rice yield than the control(no siliconfertilizer) and the yield of the two treatments increased by 64.53% and 23.49%, respectively, but rice yield didnot increase with the application of increasing amount of silicon fertilizers. The field experiment results showed that the yield of 6 rice cultivars significantly increased as steel slag silicon fertilizer was applied, of which,‘SuXiu 867'appeared to be the most sensitive to silicon fertilizer, its yield increased by 40.77% compared withthe control, and it was a rice cultivar with high silicon uptake efficiency and accumulation. As the paddy fieldin mountainous area of southern Anhui Province was concerned, the optimum application amount of siliconfertilizer and the selection of cultivars with high silicon uptake could effectively improve the rice yield andobtain high economic benefits.
