该文较为系统地阐述了品黑一号的亲本来源、选育过程、特征特性、营养品质以及重金属含量安全等相关问题,其中4个样品中硒含量变幅在0.035~0.57mg/kg,平均为0.29mg/kg,达到富硒标准;铁含量超过检测低限15%以上;锌含量超过检测低限4倍以上。经过标准化生产的黑米重金属镉含量到达检测低限以下,低于国家标准4~5倍,达到有机标准。
This paper systematically expounded the related sources such as the parental origin, breeding process, characteristic traits, nutritional quality and safety of heavy metals in PinYao-1. The content of selenium in the four samples ranged from 0.035 to 0.57 mg / kg, the average 0.29mg / kg, up to the selenium standard; iron content over the detection limit of 15% or more; zinc content more than 4 times the detection limit. After standardized production of black rice heavy metal cadmium content below the detection limit below 4 to 5 times the national standard, to organic standards.
