摘 要：
根据郑辑之《永嘉郡记》(公元四世纪)记载,永嘉地区(即今浙江温州一带)一年能养八批蚕。当时人民已经发现用低温催青蚕卵,有利于产生不滞育卵。为了能在一年四季里分批多次养蚕,创造采用低温催青办法以不断获得产不越年卵的蚕。同时还从蚕丝产量看到养越年化蚕比养不越年化蚕更为有利。所以又利用各代不越年化蚕所产的卵,在自然高温下孵化,以获得各代越年化蚕作为蚕丝生产主要蚕种。这样既解决多次养蛋的蚕种问题,同时又尽可能达到较好的蚕丝生产目的。这是我国古代养蚕技术上的一项重要发明,它充分反映了我国古代人民的勤劳与智慧。

摘 要：
In Cheng Chi-chih's "Records of The Yungchia Prefecture" (written in the fourth century) it is mentioned that in Yungchia (now southern part of Chekiang Province) silkworms could be raised in eight rearing periods (four generations) each year.The present work deals with the technical details of sericulture in ancient China and has ascertained that low temperature incubation was the method adopted by our ancestors to avoid the production of diapausing eggs so as to enable continual rearing of the silkworms.It is known that the cocoons produced by multivoltine races are inferior to those produced by bivoltine races.In ancient China low temperature incubation (eggs stage prolonged to about 21 days in dark places) was only used for securing non-diapausing eggs which were essential for the continual rearing in each year but not for cocoon production which could be better achieved by incubating the eggs with natural temperatures (egg stage about 7 days).
