摘要
对引进的 4个雄蚕品种进行了饲养试验 ,结果表明 :参试雄蚕品种的幼虫历期与现行普通种差异不明显 ,雄蚕品种的雄蚕率均达 98%以上 ,雄蚕品种的上茧率比现行品种高 1 .1～ 4.0个百分点 ,收茧量、担桑产值和张种产值分别比现行品种高 8.42 %～ 1 9.81 %、6 .0 1 %～ 40 .5 5 %和 2 5 .73%～ 40 .5 4% ,雄蚕茧的茧层量、茧层率和干壳重均明显高于现行品种。根据雄蚕产业的独特性 。
The experiment in the introduction of four male silkworm varieties was conducted,the results showed that there was not significant difference between the larval developmental duration of male silkworm varieties and that of common silkworm variety,the male silkworm rate of male silkworm varieties was over 98%. The reelable cocoon rate,cocoon yield,output value per dan of mulberry leaves and output value per egg-card of male silkworm varieties were respectively increased by 1.1%～4.0%,8.42%～19.81%,6.01%～40.55% and 25.73%～40.54% as compared with those of common silkworm variety. The cocoon shell weight,rate of cocoon shell weight and dried cocoon shell weight of male silkworm varieties were obviously higher than those of common silkworm variety.According to the characteristics of male silkworm rearing,the basic conditions and prospects of applying male silkworm varieties in Jiangxi province were analysed.\;
