硒肥对早、晚季水稻精米和米糠中硒含量变化的影响

Impact of External Se Fertilizer on Se Content in Early and Late-season Polished Rice and Rice Bran

以23个基因型不同的水稻品种为材料,早、晚季齐穗期喷施硒肥,研究硒肥对早、晚季水稻精米和米糠中硒含量变化的影响。结果表明,早、晚季喷施外源硒肥均能显著增加精米和米糠中硒含量;不同的水稻品种对硒的富集能力差异很大;大多数的水稻品种晚季喷施外源硒肥的效果显著优于早季。

Using 23 rice varieties with different genotypes as the tested materials, the Se content in the polished rice and rice bran of early and late - season rice sprayed by Se fertilizer in their full heading period was analyzed. The results indicated that spraying external Se fertilizer could apparently increase the Se content in the polished rice and rice bran of early and late -season rice; the dif- ferent rice varieties had significant difference in Se concentrating capacity; as far as most tested rice varieties, the effect of spraying external Se fertilizer on late rice was apparently better than that on early rice.
