【摘要】 通过对原原种“湖”、“滨”、“明”、“光”各龄原蚕体重、发育经过、原种繁育逐日发蛾制种比例的调查,采用桑园增施有机复合肥,合理调节原原种出库催青期差,精细饲养原蚕,加强簇中管理和发蛾调节等技术,“湖·滨”、“明·光”原种春季克蚁制种量达到15.1～18.2张,秋季12.4-14.8张,良卵率春季97.75%以上,秋季97.12%以上。近4年繁育表明:这对原种的原原种具有体质强健好养,全茧量重,茧层率高,交配性能好,卵质优良等特点。更多还原

【Abstract】 By investigating items such as the parent silkworm body weight of“Hu”“Bing”“Ming”“Guang”original silkworm eggs in different instar,the duration of developmental stage,the ratio of emergence and eggsproduction day-by-day,using the methods such as increasing organic fertilizer to mulberry field,properincubation,careful rearing parent silkworm,strengthening management in mounting stage and emergenceregulation,eggs crop of per gram of newly-hatched larvae of“Hu·Bing”and“Ming·Guang”parent eggs was15.1～18.2 cases in spring,12.4～14.8 cases in autumn,the percentage of good eggs reached cover 97.75% in spring.97.12% in autumn.In past Four years multiplication results showed these variety have characteristics such asstrong physique,easy rearing,high yield of whole cocoon weight and cocoon shell rate,excellent quality of matingand eggs.更多还原
