摘要
家蚕春制越年种在产卵后15—35日(23—26℃)浴消(水温和液温20—28℃,有效氯0.1％—0.2％,10分钟),以散卵方式保存,对蚕卵的滞育性有微弱影响,但不会出现再出卵,冬季也不会过早活化;其不良卵的发生率比平附型保护种低0.5％—1.0％,霉死卵率低1.0％—3.0％;蚕卵的实用孵化率、疏毛率和减蚕率等均未受到影响。除防止蚕种发霉、生虫,提高卵质外,该法还有很大的经济效益,能提高设备利用率近1倍,还可大幅度节省保种成本。
If the silkworm hibernating eggs produced in spring were loosed and disinfected (water and liquid temperature 20 -28 ℃ ,available chlorine 0. 1 - 0. 2% , 10min)within 15 -35 days(23-25 ℃ ) after oviposition,and then were preserved by loose eggs method, the diapause of eggs would be affected slightly by the method,but there would not be colored non-hibernating eggs,and the eggs wouldn't be activated earlier than the control in winter. The percentage of mildewed dead eggs was 1. 0 - 3. 0% lower than that of the control,and the percentage of abnormal eggs of the test was also 0. 5-1. 0% lower than that of the control. The hatchability for practical use of the eggs and the percentages of both'Keburui'and missing larvae were the same as the control. Except preventing eggs to mildew,using the method can improve the quality of the eggs and there will be great economic benefit. It can raise the equipment efficiency near to onefold and save the production cost by a large number
