摘要/Abstract

摘要：

【目的】 研究新疆南疆气候条件下水稻主栽品种喷硒肥的吸收转移特征,分析硒肥种类与浓度交互作用对水稻籽粒硒含量的影响,为新疆南疆富硒水稻的种植生产提供理论依据。【方法】 以新疆南疆阿克苏地区主栽水稻品种新稻11号为材料,采用纳米硒、亚硒酸钠和有机硒类的硒肥,设置2.5、5、10和20 mg/L 4个喷施浓度的组合试验,研究叶面喷施硒肥对水稻植株硒吸收和转运的影响。【结果】 硒肥处理均可显著提高稻米中的硒含量。籽粒、精米、叶片和茎部中的硒含量均随硒肥浓度的增加而提高;3种硒肥对稻米的富硒效果为有机硒>亚硒酸钠>纳米硒。喷施纳米硒肥时大部分硒积累在谷壳和米糠中,精米中的硒含量提高较少,而喷施有机硒和亚硒酸钠则使籽粒或精米的硒含量均显著提高。【结论】 20 mg/L的有机硒和亚硒酸钠对水稻硒生物强化的效果最佳,使精米硒含量分别提高到0.88和0.72 mg/kg。

Abstract:

【Objective】 To explore the characteristics of selenium uptake and transport in rice under the conditions of the local climate and main varieties in southern Xinjiang, and to clarify the effect of interaction between selenium fertilizer type and concentration on selenium content in rice grains in the hope of providing theoretical basis for the planting and production of selenium-enriched rice in southern Xinjiang. 【Methods】 The main rice variety Xindao 11 in Aksu, southern Xinjiang was used as the material, and the selenium(Se) fertilizer of nano-Se, sodium selenite and organic Se were applied to set up four spraying concentrations of 2.5, 5, 10 and 20 mg/L, then the effects of foliar spraying of Se fertilizer on Se uptake and transport in rice plants were studied. 【Results】 The results showed that different Se fertilizer treatments significantly increased the Se content in rice.The Se content in grains, polished rice, leaves, and stems increased with the increase of Se fertilizer concentration.The Se-enriched effect of three types of Se fertilizers on rice was: organic Se > sodium selenite > nano-Se.When spraying nano-Se fertilizer, most of the Se accumulated in rice husk and rice bran, and the Se content in polished rice increased not too much; while spraying organic Se or sodium selenite significantly increased the Se content in grain or milled rice. 【Conclusion】 In summary, 20 mg/L organic Se or sodium selenite has the best effect on Se biofortification of rice, and the Se content of polished rice is increased to 0.88 and 0.72 mg/kg.
