大蚕地面育的优势及对蚕茧产量与品质的影响试验

Analysis of Large Silkworm Ground Cultivation and Influence on Yield and Quality of Silkworm Cocoon

地面育是大蚕省力化饲养技术之一,早已在江浙和两广蚕区的生产中应用。为了帮助川渝地区的蚕农更加合理地选择和应用大蚕省力化饲养技术,对地面育的技术和成本优势以及存在问题进行分析,同时通过地面育与蚕台育的对比试验,探究了地面育对产茧性能、蚕茧品质的影响。根据分析与试验结果认为:大蚕地面饲育操作简单、省工省力、节约成本,但存在空间利用率低,春季和晚秋季容易受低温影响等缺点;相对于蚕台饲育,地面育生产的原料茧上茧率、解舒率等稍逊。因此,蚕农是否选择地面育,需要综合考虑劳动力成本、产茧性能、蚕茧品质、气候环境等多种因素。

Ground breeding is one of the labor-saving breeding techniques of large silkworms,and it has always been one of the large silkworm breeding methods chosen by farmers in Jiangsuand Zhejiang areas and Guangdong and Guangxi areas.In order to help the silkworm farmers in Sichuan and Chongqing region to choose and apply the labor-saving breeding technology more reasonably,the technology,cost advantages and existing problems of ground breeding are analyzed,and the influence of ground breeding on cocoon performance and cocoon quality through the comparative test of ground breeding and silkworm cultivation is explored.According to the analysis and test results,it is concluded that the ground feeding has simple operation,labor saving and cost saving,with low space efficiency and low temperature in spring and late autumn,and compared with silkworm feeding,the cocoon rate and relaxation rate of raw materials produced by ground feeding are slightly inferior.Therefore,whether the silkworm farmers choose the ground breeding,we need to comprehensively consider the labor cost,cocoon production performance,silkworm cocoon quality,climate and environment and other factors.
