摘要： 采用AS系列负氧离子(O-2)发生器,使蓖麻蚕、家蚕1～5龄生活在空气富含O-2(浓度>5×104N/cm2)的蚕室中,按蛹、蛾、卵、蚁蚕、蚕系列生殖发育顺序,系统地研究了负氧离子对它的影响与作用。结果表明:处理组比对照组出蛾齐一,羽化率增高,产卵速度加快,总产卵量增多,良卵率加大,不受精卵率减少,胚子发育整齐,孵化齐一,孵化率增高,并在一定程度上能增进次代蚕的强健度。另外,幼虫期和卵期环境中都补充O-2,可使实用孵化率极显著地高于对照1138个百分点(家蚕)和908个百分点(蓖麻蚕),而只在卵期补充负氧离子,也可有效地促进胚子发育与孵化齐一,获得与整个蚕期补充O-2相近效果。

Abstract: Raising eri silkworm( Philosamia Cynthia ricini B) and silkworm ( Bombyx mori L) (1 5 larval or ovum stages) in the raising room with rich negative ions of oxygen(510 Ncm)by using negative ions of oxygen generators of AS series.The influence and effect of negative ions of oxygen on silkworm was studied by the genital and developing order of pupaes,moths,ova,antsilkworms and silkworms.The result showed that the treated group eclosion is uniformer and the eclosion rate are higher;The speed of laying eggs is faster,the total laying enhances,the good laying rate increases and unzygotes reduces;The embryos grow orderliness and the hatched is uniformer,the hatched rate enhance and the sturdiness of offspring silkworm is furthered.Moreover negative ions of oxygen is supplied in the surroundings during the larva and ovum period,which makes practicaly hatched rate are higher percent 11 38(silkworm) and 9 08(eri silkworm),however,negative ions of oxygen is completed only during the ovum period,which can effectively enhance those and gain the same effect,compared to the silkworm period.
