英文摘要: The Selenium degree of crops was investigated in key area of Cili,we found that most of the ten kinds of crops that we collected reached the selenium-rich standard,by establishing the related crop standards of Hunan province. Among them,the average content of selenium in rape,rice and maize were the highest,up to 0.285,0.136 and 0.118 mg/kg. By comparing the selenium content in the root soil,the selenium enrichment law of ten crops was studied,and the selenium enrichment coefficient was obtained. The selenium enrichment capacity of rape was the strongest,followed by soybean and garlic. According to the selenium content of soil and crops in Cili,selenium-rich agricultural development suggestions of Cili were throw out.
中文摘要: 针对慈利县重点区域进行了农作物富硒程度专项调查,通过建立湖南省相关农作物富硒标准,发现采集的十种农作物中大部分达到富硒标准,其中油菜、水稻、玉米等硒平均含量最高,分别达到0.285mg/kg、0.136 mg/kg以及0.118 mg/kg。通过对比根系土硒含量,研究了十种作物硒富集规律,得出了各农作物硒富集系数,油菜硒富集能力最强,其次为大豆、大蒜。针对慈利县土壤、农作物含硒量特征提出了慈利县富硒农业发展的建议。
