换气孔数量及饲养台姿态对蚕儿生长和茧质性状的影响

Effect of Vent Number and Feeding Table Posture on the Growth and Cocoon Quality of Silkworm

探讨换气孔数量及饲养台姿态对家蚕生长和茧质性状的影响。饲养蚕筐设置40个和80个孔径为10 mm的换气孔区,再将换气孔区分为饲养台水平区和倾斜区,倾斜区两长边高度分别为4 cm、6 cm。结果显示,4个试验区2龄眠蚕体重处于同一统计水平,均大于对照区,且与对照区有显著差异;茧质调查结果表明,40孔水平区的全茧量与对照存在显著差异,其他试验区的全茧量、茧层量和茧层率无显著差异。

Effect of vent number and posture of feeding table on the growth and cocoon quality of silkworm was studied.The silkworm basket was installed 40 and 80 vent areas with a diameter of 10 mm,and these areas were placed into horizontal area and inclined area.The two long sides of inclined area was 4 cm and 6 cm high.The results showed that the weight of 2 nd instar molter silkworm of four test areas was at the same statistical level,which was all higher than that of the control,with a significant difference between them.The result of cocoon quality investigation indicate that the whole cocoon weight of 40 vents horizontal test area was of significant difference in comparison to the control.The whole cocoon weight,cocoon shell weight and cocoon shell rate of the other test areas were of no significant difference.
