Silkworm sleep from the processing technology

The level of sericulture technology and the level of silkworm cocoon production are mainly reflected in how well the processing of silkworms begins. Sleep treatment consists of three processes: pre-sleep treatment, sleep protection, and silkworm treatment. 1, before going to bed to deal with silkworms into the deprivation period, should sleep, feed 1-2 back leaves, going to sleep and sleep in addition to sleep silkworm dry silkworm seat. Before going to sleep, the amount of mulberry is gradually reduced. It is neither a waste of mulberry leaves, but also conducive to formation and screening of silkworms. After the vast majority of silkworms slept, 1 to 3 instar silkworms use 3 parts of eschar and 7 parts of fresh lime powder; 4 to 5 instar silkworms use fresh lime powder to spread in silkworms and carry out mulberry sprouting, then raise green nets. The silkworm nets were transferred to another silkworm cocoon, and the green head silkworms were merged and then placed on the upper shelf of the silkworm frame. High-quality mulberry leaves were fed to promote development and a large number of silkworms could catch up with the development progress after 3-4 days. Pay attention to observing the green headed silkworm, and weed out the weak and small diseased silkworms in time. Qingtou silkworm should be kept alone, not with a large number of silkworm polyculture, to prevent silkworm infection. 2. The effect of temperature on the length of silkworm protection during sleep is obvious. According to the normal temperature protection, the sleep period is about 22 hours for 1 instar, 18-20 hours for 2nd instar, 24 hours for 3rd instar, and 4 instar. 44 - 46 hours. The temperature during sleep is about 1°C lower than usual breeding time, the early period of silkworms' sleep (beginning to peeling before foraging), and the difference between wet and dry is about 2°C, and the humidity is slightly better than that of cannibalism. Sleep environment should be quiet; light should be dark; keep the air fresh; to prevent strong wind blowing. 3. The head of the silkworm cocoon treated with cocoon silk was pale brown and suitable for food-feeding. The postponed feeding was appropriate to facilitate the development of the cocoon. It had no adverse effects on the silkworm constitution and silkworm cocoon production. In spring silkworm, 90%-95% of silkworm silkworms in mid-to-late autumn are foraging, summer silkworm and early autumn silkworms have higher temperatures, and 85%-90% of silkworm cocoon skins are foraging. Before eating, use silkworm net or disease prevention No. 1 or anti-stiff drugs to disinfect silkworms and silkworms to facilitate the killing of germs. After feeding, feed two back leaves to get rid of. If silkworm heads are more compact and not grouped before sleep, if silkworms are missing, then they can be divided into two groups. For example, silkworms and silkworms can be sterilized. Silkworm nets, after a few hours, wait until the silkworms have been molted for the second time. There are two methods for feeding and feeding in batches: one is to add two silkworm nets (each occupying half of the area of ​​silkworms) for each silkworm cocoon, and to put one silkworm cocoon on each silkworm net, ie Two silkworms. Another method: Each silkworm cocoon firstly adds a silkworm net, and the silkworm silk net area is slightly larger than the silkworm cockroach. After the silkworm climbs to about half of the silkworm net, the silkworm net is lifted, and the other half of the silkworm silkworm is re-screened to the silkworm. except. This saves time for expansion and the silkworm body is not injured. The leaves should be ripe and tender, and the amount of leaf should be reduced to prevent waste. As the amount of mulberry eaters increased, the amount of leaf feeding increased.
