五种小蚕饲育方式对蚕儿生长和茧质性状的影响
|
摘要
为探讨小蚕饲育方式对蚕儿生长的影响,进行了浅塑料筐养蚕比较试验。将塑料筐养蚕分设成有饲养台区和无饲养台区,有饲养台区细分为石灰区、置换区和高架区,无饲养台区细分为覆膜区和空白区。结果表明:5种饲育方式的全茧量、茧层量、茧层率无显著差异;2龄眠蚕体重石灰区、置换区与覆膜区,以及与高架区、空白区有显著差异;石灰区、置换区对BmNPV的抗性优于空白区。
The comparison of five feeding manners was conducted in order to study the adverse influence of air quality to the growth of young silkworm.The feeding tools is shallow plastic crate that setting feeding table and no feeding table regions.The feeding table regions were divided into lime area,replacement area and elevated area,and the no feeding table regions into film covered area and blank area.The experiment proved that there was no significant difference in the whole cocoon weight,cocoon shell weight and cocoon shell percentage among five feeding manners.There was significant difference in the weight of 2 nd instar moulting larvae between lime area,replacement area and elevated area,and film covered area and blank area.The resistance to BmNPV of young silkworm in replacement area and lime area is superior to blank area.
