摘要:

为明确栽培技术对不同稻作区稻谷硒含量的综合影响,基于国内外相关文献,定量分析了施肥、灌溉、石灰施用等栽培措施对稻谷硒含量和产量的影响,并比较了不同水稻品种间硒含量的差异。结果表明,与不施肥相比,施用氮磷钾肥能促进稻谷硒的积累;紫云英还田可明显增加稻谷硒含量,其增幅与紫云英的投入量显著正相关;其他有机肥对稻谷硒含量的影响在不同研究中存在差异。间歇灌溉和湿润灌溉等节水管理和施用石灰可有效提高稻谷硒含量。不同水稻品种积累硒的能力差异显著,且这种差异不受土壤硒含量影响。选用富硒水稻品种、紫云英还田、节水灌溉和适量施用石灰等栽培措施可以实现水稻天然富硒与高产的协同。

Abstract:

The objective of this study is to clarify the effects of cultivation measures on rice Se content in different rice cropping regions. Based on the relevant literatures at home and abroad, this paper quantitatively analyzed the effects of fertilization, irrigation, lime application and other cultivation measures on the selenium content and rice yield, and compared the differences in selenium content among different rice varieties. The results showed that the application of N, P, K fertilizer could promote the accumulation of selenium in rice compared with no fertilizer application. The return of vetch to the field could increase the selenium content of rice, and its increase was significantly positively correlated with the amount of vetch. The effects of other organic fertilizers on the selenium content of rice differs in different studies. Water-saving management such as intermittent irrigation and wet irrigation and application of lime could improve the selenium content of rice. There were significant differences in the ability of different rice varieties to accumulate selenium, and this difference was not affected by soil selenium content. Cultivation measures such as selection of selenium-enriched rice varieties, return of vetch to fields, water-saving irrigation and appropriate application of lime could achieve the synergy of natural selenium enrichment and high yield in rice.
