塑料方格蔟应用效果分析

Analysis of the Application Effect of Plastic Grid Nesting

经在同一环境中用塑料方格蔟、木板方格蔟和塑料折蔟3种蔟具上蔟对比,全茧量、茧层率等茧质指标相近;塑料方格蔟的上车茧率和解舒率最高,一茧丝长最短;木板方格蔟的一茧丝长最长,万米吊糙最低;塑料折蔟主要丝质指标均低于2种方格蔟。平均每张蚕种从上蔟到采茧全过程的操作工时分别为,塑料方格蔟39 min、木板方格蔟62 min、塑料折蔟190 min。监测上蔟后4 d内的蔟中温湿度发现,3种蔟具微环境中温度差异不大,塑料折蔟相对湿度明显高于2种方格蔟。

In the same environment with comparison of plastic square nest,wooden square nest and plastic folding nest,the whole cocoon weight,cocoon layer rate and other cocoon quality indicators are similar;plastic square nest on the reelable cocoon rate and reelability is the highest,a cocoon silk length is the shortest;wooden square nest cocoon silk length is the longest,the lowest 10000 metres of hanging brown;plastic folding nest are lower than the two kinds of square nest main silk quality indicators.The average labour time of each silkworm from nesting to cocoon harvesting were 39 min for plastic square nest,62 min for wooden square nest,and 190 min for plastic folding nest respectivile,and the temperature and humidity in the nest were monitored for 4 d.The temperature and humidity in the nest were found to be not much different in the micro-environment of the three types of nests,and the relative humidity of the plastic folding nest was higher than that of the two other types of square nests.
