用~(60)Coγ射线辐照文蛤幼贝,研究其对文蛤生长及抗病性的影响。A组预试验结果表明:低剂量~(60)Coγ射线辐照对促生长有效,高剂量辐射抑制了文蛤生长。B组正式试验辐照剂量(低剂量)3.23×10-7～25.80×10-7C/kg。低剂量辐射试验结果表明:46d后,试验组平均壳高及平均体重均高于对照组,分别增加15%～21%和16%～26%;276d后,试验组的平均壳高较对照组增加17%～23%,且试验组文蛤的抗病性远优于对照组。6.45×10-7～19.35×10-7C/kg低剂量为促进文蛤幼贝生长、提高抗病性的有效剂量范围。
The effects of irradiation on the growth and disease resistance of the black clam were studied by irradiation with ~ (60) Coγ ray. A group of pre-test results show that: low dose of ~ (60) Coγ-ray irradiation to promote effective growth, high dose radiation inhibited the growth of clam. Group B formal test irradiation dose (low dose) 3.23 × 10-7 ~ 25.80 × 10-7C / kg. The results of low-dose radiation test showed that after 46 days, the average shell height and average body weight of the experimental group were higher than that of the control group by 15% -21% and 16% -26% respectively. After 276 days, the average shell height of the experimental group was higher than that of the control group Increase 17% ~ 23%, and the experimental group clam’s disease resistance is far better than the control group. 6.45 × 10-7 ~ 19.35 × 10-7C / kg The low dose is an effective dose range for promoting the growth of the mussel and improving the disease resistance.
