摘要
研究在南方高温多湿季节采用降温排湿措施对蚕茧产量及质量的影响。结果显示,采用降温排湿措施的试验区比自然条件下的对照区平均温度降低1.13～3.11℃、平均湿度降低2.51%～5.02%、病死蚕数低57.4%、产茧量多4.8kg/张,在解舒率、上车率、匀净度、茧丝长、全茧量和茧层率等方面均比对照区高。表明在南方高温多湿季节采用搭凉棚、盖遮阳网、安装排风扇、开设地脚窗结合撒石灰、条桑育蚕等简便措施,能有效降低蚕房的温度和湿度,提高蚕茧产量和质量。
In the experiment, the effects of decreasing temperature and removing humidity on the yield and quality of cocoon were studied in high temperature and humid season of southern China, and the results showed that the treatments for decreasing temperature and removing humidity decreased temperature by 1.13-3.11℃ and humidity by 2.51%- 5.02%, respectively, as compared with the control in natural condition, also decreased the dead silkworms by 57.4% and increased the cocoon by 4.8 kg per pieces. Moreover, the reelability ratio, reelable cocoon ratio, cleanliness, cocoon fila- ment length, whole cocoon weight, cocoon layer ratio of treatments were also higher than those of the control. Therefore, it could decrease the temperature and humidity of silkworm room and increase the yield and quality of cocoon through putting up cool greenhouse, covering with sunshade net, installing ventilator, opening bottom windows and applying lime, and raising silkworm with mulberry branches in high temperature and humidity season of southern China.
