“强桑1号”条桑省力化饲育对比试验

Comparative Experiment on Labor Saving Feeding of"Qiangsang No.1"Mulberry

为探索提高蚕桑生产劳动效率、降低蚕桑劳动强度的方式,于2020年在淳安县进行了“强桑1号”大蚕条桑省力化饲育与普通片叶育的对比试验。结果强桑1号条桑育的每667 m^(2)桑产叶量为915.8 kg,比片叶育的925 kg减少了2.5 kg;张种采叶喂叶用时为37.2 h,比片叶育的47.1 h减少了9.9 h;张种产茧量42 kg比片叶育的39.5 kg提高了2.5 kg。结果表明,“强桑1号”条桑育比片叶育省工省力,增效281.19元/张,增幅达17.4%。

The comparative experiment was carried out in Chun'an County in 2020 between labor-saving feeding with mulberry branches and ordinary leaf feeding using"Qiangsang No.1"as grown up silkworm rearing.Results showed that the leaf yield per mu of"Qiangsang No.1"by branch harvesting was 915.8 kg,2.5 kg less than that of 925 kg for leaf collection;however,the feeding time was 37.2h which is 9.9 h less than that of 47.1 h by leaf feeding.The cocoon yield per box was 42 kg,which was 2.5 kg higher than 39.5 kg by leaf feeding.In summary,branch feeding of"Qiangsang No.1"was labor-saving,with an increase of 281.19 yuan/box,that is an increase of 17.4%.
