摘　　要：本文通过抗辐射菌培养物添食,调查了其对家蚕茧生产性能的影响。初步结果显示:5龄添食抗辐射菌培养物能提高家蚕茧的产质量,且没有延长5龄经过时间,与空白对照相比,0.2%、0.5%及0.8%添食区,全茧量分别提高5.1%、7.2%和9.3%,茧层量分别提高4.6%、8.2%和8.8%,对生命力也无不良影响;不同添食时间的试验结果表明,添食时间越早,抗辐射菌培养物对提高家蚕茧的产质量的效果越明显,3龄起蚕添食区的全茧量与茧层量分别比空白对照增加10.2%和11.3%。To study the effects of D.radiopugnance inoculum on development and cocoon quality of silkworm.Larvae were fed on different concentrations D.radiopugnance inoculum at different developmental stage,and cocoon quality was investigated.It is found： feeding D.radiopugnance inoculum at newly moulted 5th larva can improve cocoon production without prolonging 5th instar and adverse affect on vitality.Compared with control,0.2%,0.5% and 0.8% feeding area,cocoon weight increased 5.1%,7.2% and 9.4%,cocoon shell weight increased 4.6%,8.2% and 8.8% respectively;feeding time test results showed： the earlier feeding,the more obvious effects on cocoon yield and quality were observed,for newly moulted 3rd larva feeding silkworm,the cocoon weight and cocoon shell weight increased 10.2% and 11.3%,respectively,compared with that of control.
