【摘要】 我国从1964年开始应用自然放射源照射柞蚕卵,虽获得良好的增产效果,但防护运输不便。1976年,改用吉林师大物理系制造的轻便中子发生器产生的纯中子照射柞蚕卵试验,结果证明:蚕卵经100/cm~2照射后,蚕儿体强、好养,处理小区比对照区平均增产30％,每斤蚕卵增丝五斤之多。 中子发生器产额10~8中子/秒,12分钟即可照射柞蚕卵500多市斤,大大地提高了照射效率。中子发生器在非照射时间无任何放射性,不需防护,安全、重量轻,便于运输,适于蚕区使用。更多还原

【Abstract】 In 1964 we used natural radio-active generator to radiate tussah oviposition by which al though we obtained success to increas-production but it gave any trouble in safe-guard and transferability.In 1976 we used portable sealed-tube neutron generator which was made by kirin normal university physic department to radiate tussah oviposition. The fruitful research said that when tussah oviposition suffered 109 neutron radions per cm2, all the incubated tussah had got stronger bodies and better lives. At last the production is more thon 30% over non-radiated district, e. i per kg weight of tussah oviposition the increasiny production of silk is 5 kg.The pure neutron generator yeilds 108 neutrons. It can radiate tussah ovipa-sition more than 250 kg within 12 minutes and gives out well radiated efficiency, while in the non-parated period it gives no radio-activity and needs not safeguard. It ocuppies portoble size, safety and application in tussah districts.更多还原
