规模养蚕新技术的研究 II.大棚蔟中温湿度对蚕茧丝质的影响

Studies on New Techniques of silkworm Rearing in scale 1 The Effect of Temp. and RH in Green House with Plastic Film on the Quality of Silk

记录了大棚养蚕上蔟24h～48h之间的棚内温湿度变化。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。棚内湿度春、夏期在上蔟28～30h时出现最低值,40～48h时出现最大值。春蚕期高湿的持续时间长于夏蚕期。大棚养蚕上蔟初期的通风排湿比室内饲养要求更高。

The variation of temp. and RH in the green house with Plastic Film during cocooning stages in spring and summer rearing were recorded and the effect of which on the silk quality was analyzed. The results indicated that the highest temp.,38.2℃,appeared in 32h in spring, and 38.7℃ in summer after cocooning. The lowest humidity appeared during 30 h～32 h and the highest humidity during 40h～48h after cocooning both in spring and summer. The duration of high humidity lasted much longer in spring than that in summer. It was more important to discharge the moisture during beginning stage of cocooning in the green house than that in the rearing room.
