上蔟

并对蚕茧丝质的影响比较分析表明，春蚕期上蔟28h出现38.2℃的最高温度，夏蚕期在上蔟后32h出现38.7℃的最高温度。缩短春蚕期幼虫全龄经过的方法

The results indicated that the highest temp . , 38.2 ℃, appeared in 32h in spring , and 38.7 ℃ in summer after cocooning . Research on Methods for Decreasing the Duration of Whole Larva Instar During the Period of Spring Silkworm

家蚕自动上蔟技术研究

Studies on Automatic Cocooning Techniques

通过调查不同上蔟环境中所结蚕茧的性状，发现合理上蔟环境中所结的蚕茧茧质优；

Based on the character investigating of cocoons spun at different mounting conditions , it was found that the proper condition brought about the high quality cocoons .

和大部分鳞翅目昆虫一样，家蚕具有精子二型性：上蔟吐丝前产生有核精子，之后则产生无核精子。

As most of the Lepidopteran insects , the silkworm has sperm dimorphism . They generate sperm with nuclei before the silkworm spinning , after that , they produce sperm without nuclei .

在恶劣的上蔟环境中结成的蚕茧，茧色黄而深浓，茧层手触紧硬而弹性弱，缫丝时落绪多，解舒差。

The cocoon spun in poor mounting conditions shows yellow and dark colour , tough hand feeling and weak elasticity , resulting in more dropped ends and lower reelability percentage during silk reeling .

棚内温湿度变化对蚕茧产质量的影响比较分析表明，春期5龄后期和上蔟初期35～38.8℃的高温对蚕茧产质量有较大影响；

And RH in the green house during grown larvae and cocooning stages in spring and summer rearing were conducted . The results indicated that there was a great effect of high temp . between 35 ~ 38.8 ℃ on cocoon quantity and quality in spring , more higher temp .
