Xiaqiu sericulture three anti-three early
Three defenses Prevention of pests and diseases focuses on thorough sterilization before sericulture. From 3 days to 5 days before silkworm rearing, silkworms, silkworms, and the surrounding environment are thoroughly cleaned and washed. Specific methods: Disinfect with 1% bleach solution twice in succession and keep it moist for half an hour each time. Silkworm cocoons and silkworm nets must be washed and dried more, and silkworms should be disinfected by collecting ants and adding nets. After removing sand, disinfectants should be ground and space sprayed with a 1% bleach solution containing available chlorine. In order to prevent silkworm disease, since the third instar feeding, the chloramphenicol aqueous solution was added once a day at noon, and the pesticide was poisoned in the silkworm, and it was immediately detoxified with 1% edible alkaline water. In order to prevent fly larvae damage, we must add food and eliminate flies from time to time on the third instar. Anti-smuggling silkworm room should use cool and well-ventilated houses. Silkworm cocoons should not be directly facing the silkworm room doors and windows, nor can they be directly blown with fans. The best way is to install an exhaust fan, cover the grass on the roof and spray water to cool it, spray water around the brick wall to reduce heat. The continuity of silkworm feeding is directly related to the continuous growth of silkworms, so silkworms cannot be starved. Small silkworms cut slightly larger leaves, and 3rd instar silkworms can feed the whole leaf. To feed less, feed six times a day, the large silkworm will feed as it feeds, and it is better to feed more at night. Three mornings As soon as the ant hatches the ants, it is necessary to sweep the ants with silk feathers and move them to the silkworms in time. Otherwise, if they are scattered for a long time, they will cause losses. At least two times a day, they will be collected at 5 points, and they will be collected at 7 points. Feeding and feeding in batches. Early grazing can be eaten when peeling accounts for 80% of the time. When feeding, the mulberry leaves must be fresh. Gradually increase the mulberry leaves to avoid overeating. As early as the day, the hot silkworm grows faster. It is necessary to expand the seat early to release silkworms. Can't wait until crowded before expanding, as it will affect the normal growth of silkworms.
Oxygen Flow control regulators and conserving devices are pressure reducing devices designed to regulate or lower oxygen pressure from a cylinder to levels that can be safely used by the patient. A Regulator simply regulates the (free) flow from an oxygen cylinder. A Conserving Device is an entirely different kind of device that delivers a "pulse" of oxygen as the patient inhales (on demand).
