《农桑辑要·蚕事预备·三稀》
《蚕经》：将孵化出的蚁蚕，收集到蚕座上饲养时要稀；将蚕布入蚕箔时要稀；放老熟上簇时要稀。
《蚕经》：下蚁，上箔，入簇。
"Sericulture Classics": When the hatched ant silkworms are collected and raised on the silkworm seat, they should be kept sparse; when the silkworms are put into the silkworm skein, they should be kept sparse; when they are put on the ripening stage, they should be kept sparse.
