摘 要: | 黑龙江省属缺硒省份,尤以大兴安岭、小兴安岭、东南部山地和三江平原地区最为严重。松嫩平原的某些县含硒量稍高,但亦属低硒地区。全省土壤硒水平范围值为0.0117—0.6314ppm,平均值为0.1605ppm。水溶性硒水平范围值小于0.1—15.8ppb。饲料硒水平因地区不同差异亦显著。如低硒地区(病区)与非低硒地区(非病区)的玉米含硒量平均值分别为0.0065与0.0215ppm。

SELENIUM CONTENT AND DISTRIBUTION IN SOIL AND FEED IN HEILONGJIANG PROVINCE |
| |
Abstract: | Heilongjiang province is an area deficient in selenium.the most severedeficient areas are the Xingan ranges,the southeastern mountainous region andthe Sanjian plain.There is slightly more selenium in some counties of Songnenplain,where is also a part of the low-selenium regions.The soil selenium levels are from 0.0117 to 0.6314 ppm,the averag,e valueis 0.1605 ppm.The water soluble selenium levels are less than 0.1 to 15.8ppb.The levels in feed vary with various regions,for instance,the seleniumlevel in corn in low selenium regions(diseased areas)and in regions whereselenium is not too low(non-diseased,)is 0.0065 and 0.0215ppm respectively. |
