Silkworm rearing in summer and autumn should pay attention to "five preventions" and "five guarantees"

One, five defense 1, anti-pesticide poisoning. Summer and autumn silkworm is the peak period of farmland pest management. It is necessary to prevent pesticide poisoning in Qianer. Pay attention to the following points: 1 Agricultural chemicals should be kept away from mulberry fields and silkworm plots, and avoid polluting mulberry trees. When the crops near the Jamsil pests are treated, the silkworm doors and windows should be promptly closed to prevent the smell of pesticides from being eaten by silkworms; 2 The silkworm farmer should wash and change clothes before harvesting to feed silkworms or Other sericulture operations; 3 Mulberry spraying foliar fertilizer and mulberry Leaf moistening, prohibit the use of pesticides equipment; 4 during the period of sericulture should not be sprayed in the vicinity of Jamsil field pesticides and other organic nitrogen pesticides, because of its fumigation will make silkworms serious poisoning; 5 mulberry leaves to insist on feeding, confirm non-toxic Only after a large number of leaves can be fed silkworms. 2, anti-harm. Mosquito coils contain components such as pyrethrum, which can easily cause chronic poisoning of silkworms. Extermination of harmful insecticides and other insecticides are highly toxic to silkworms. Therefore, mosquito coils must not be spotted or used to kill mosquitoes and insecticides. If you are using a house near Jamsil, you must close the doors and windows of Jamsil. 3, fly prevention. In summer and autumn, the flies are more harmful to silkworms, and silkworm doors and window screens should be installed in the silkworm to prevent the flies from entering silkworms and endanger the silkworms, and the silkworm fly emulsions can be added in time to kill flies. 4, against rodent damage. Block rat holes before sericulture, keep a certain distance between the silkworm frame and the wall, and stack lime powder or silkworm worms around the silkworm's feet to effectively prevent rats from climbing up. Such as raising silkworms, they should be good at drug eradication. Cats in silkworms can significantly reduce the damage of mice to silkworms. 5, anti-high temperature. Summer silkworms and early autumn silkworms have higher temperatures, so that they can spray well water, hang damp cloth or straw curtains, close doors and windows during the day, prevent hot air flow from entering the room, and reduce the temperature at night. They should open windows and doors overnight. Da Waping roof covering grass can effectively reduce the indoor temperature. Mulberry leaves are sprayed with water, and indoor use of fans to blow the breeze is also an effective measure against high temperatures. Two or five not 1, do not litter the disease silkworm. In summer and autumn, climate is often hot and humid, germs multiply rapidly, and silkworms are susceptible to disease. Therefore, attention should be paid to prevention and control of silkworm diseases. It is found that diseased silkworms should promptly pick up and put into the disinfection hopper containing bleach solution or lime slurry. It is impossible to lose the diseased silkworm. It is forbidden to feed the livestock and poultry with diseased silkworm to prevent the spread of pathogens and pollute the environment. 2, not chaotic silkworm sand. The silkworm sand contains a large number of pathogens, which should be deposited and covered with a thin film so that it can be fermented by steaming or pour into a pit to kill pathogens. You can't arbitrarily dump the silkworms, and you can't spread them around the Jamsil to prevent the spread of pathogens. 3, do not change the quality of mulberry leaves. The high temperature and humidity in summer and autumn, pathogens multiply quickly, should be planned to collect leaves, timely transport leaves, reasonable storage of leaves, can not be stacked too thick to prevent steaming deterioration and induce silkworm disease. Storage mulberry pool should be disinfected once every age, kill germs, not eaten mulberry leaves. 4, should not be a lot of moisture. Humidity is more harmful than high temperature, so do not eat wet leaves in high-temperature and wet weather. Store the mulberry leaves and do not spray water. Diligently remove sand, and sprinkle dry materials such as fresh lime powder and dried straw to prevent germ propagation. 5, do not store food. The host of ticks is mostly larvae of cotton bollworms, rice blasts, and wheat moths, bean pods, and rapeseeds. Niches have occurred more than 10 generations a year, causing greater damage to silkworms. In addition, maggots produced by grains and bran that have been exposed to moisture for a long time will also climb on silkworms to bite silkworms. Therefore, grain and cotton cannot be stored indoors during the sericulture season. China Agricultural Network Editor
