摘　　要：2 0 0 2年 5 ,7,9月 ,对东北农牧交错带内某草甸土壤、小尾寒羊主食的 2种牧草、放牧小尾寒羊被毛中铁含量进行了分析。结果表明 ,该交错带草甸土壤中铁的总平均含量为 0 .96 % ,小尾寒羊主食的 2种牧草中铁的总平均含量为 75 9.85 μg/g ;放牧小尾寒羊被毛中铁的总平均含量为 2 33.30 μg/g。据此认为 。THE IRON CONTENTS OF SOIL, TWO KINDS OF HERBAGES PREFERRED BY CODETTA, AND THE WOOL OF CODETTA WERE DETERMINED IN NORTHEAST FARMING-GRAZING INTERLEAVING DISTRICT IN MAY, JULY AND SEPTEMBER IN 2002. THE RESULTS SHOWED THAT THE TOTAL AVERAGE CONTENT OF IRON IN SOIL OF MEADOW IS 0.96% IN NORTHEAST FARMING-GRAZING INTERLEAVING DISTRICT, 759.85 ΜG/G IN TWO KINDS OF HERBAGE PREFERRED BY CODETTA, AND 233.30 ΜG/G IN THE GRAZED CODETTAS'S WOOL. FROM ABOVE, THE GRAZED CODETTAS IN NORTHEAST FARMING-GRAZING INTERLEAVING DISTRICT CAN'T SUFFER FROM THE DISEASES OF IRON DEFECTIVE OR IRON POISONING.
