A pest and disease prevention: focus on the thorough disinfection before silkworm rearing. 5 to 7 days before silkworm rearing, comprehensive cleaning and scrubbing of the silkworm room, silkworm worm, and the surrounding environment are carried out. The 1% bleaching powder aqueous solution containing available chlorine is sprayed and sterilized twice in succession, each time being maintained for half an hour. Silkworms, etc. should be sterilized by soaking methods. After receiving ants, we must focus on the entire process of sericulture, focusing on small silkworms. Silkworms should be washed more often. Ant silkworms, silkworms, and larvae must be sterilized on time for the silkworm body. After removing sand, 0.5% bleach solution containing available chlorine is used for surface and space spray disinfection. In order to prevent silkworm disease, from the second instar feeding, daily noon will be added to the noodles once a day. Found that silkworm pesticide poisoning, it is necessary to immediately detoxify with 1% food soda water. For the purpose of preventing fly larvae, from the third instar, it is necessary to add food and flies on time and in quantities.
Second, anti-sultry heat: The silkworm room should use a cool, well-ventilated house. The silkworm cocoon stays away from the doors and windows of the silkworm room and prevents wind from blowing heat. Three anti-hungry silkworms: small silkworm leaves a little bigger, three-instar silkworm can feed the whole leaf, to feed less feeding, feed six times a day. After the silkworm eats, it is better to feed it, and it is better to feed it at night. A diligent is picking silk and removing sand. In order to prevent silkworms from losing silkworms, sand is not removed at the age of one year, but only at the second age. - Three late one morning. Accepting ants early in the morning: At 8 and 9 am, they receive ants on time and feed them along with the receiving ants. The first two days of feeding: silkworm cocoon can be picked up for food, mulberry leaves should be fresh, the amount should be less.
Three seats were expanded early and thin silkworms were released. A late: late mulberry. The silkworm will feed the leaves when it sleeps, feed less and feed it, and add silkworms, silkworms and mulberries, and eat and sleep. - Four uniform two timely. First, the temperature of the silkworm chamber is even and the height is appropriate. In summer, the temperature is changeable. Try to control high temperature and humidity or high temperature drying to reduce the temperature difference between day and night. High temperature and humidity should be strengthened ventilation, high temperature drying to spray water cooling and moisturizing. The silkworm's room temperature should be maintained at 26 °C ~ 28 °C, can not be higher than 30 °C; silkworm 23 °C ~ 24 °C, not higher than 27 °C. Second, the silkworm is evenly distributed, and the size of the silkworm should be appropriate. Summer silkworm is thinner than spring silkworm.
The third is to feed the leaves evenly, how much to give the leaves appropriate, so that silkworms can fully eat.
Fourth, mulberry leaves should be uniform and their maturity should be appropriate. The 1st to 4th instar silkworms were selected to adopt the summer harvesting of the mulberry, and the 5th instar silkworms could be combined with the second mulberry sprouts, and the new shoots were fed to the silkworm to ensure that the silkworm did not eat too old, withered, heat, insect bites. Muddy mulberry leaves. Second, timely: sleep treatment must be timely, plus sleep network earlier than the spring silkworm, uneven development to mention the green batch, multi-batch mentioning green, shorten the sang time, and smooth sleep. The captain must be timely, when the silkworm is old, it is necessary to select the captain in batches, and it should be diluted. 3 days after the last day, you must open the window to open the window and keep it wet. However, you should avoid blowing strong wind and the air flow rate should be slightly windy on your face.
The key technology operation of summer silkworm breeding
The key to raising the summer silkworm is summarized as follows: Taking the good and the satiated food as the center, the technical measures of “three preventions and one diligenceâ€, “three early and one lateâ€, and “four uniform and two timely†are used flexibly. - Three defenses and one diligence.
