First, strict disinfection and disease prevention
Due to the high temperatures and high humidity during the autumn period, the pathogens are highly virulent, and there are many diseases and insect pests in mulberry fields, which can easily cause mutual infections: Autumn silkworms are prone to short-lasting softening, pyosis, bacterial diseases, zombies, aspergillosis, and fly lice. disease. Only strict disinfection and eradication of pathogenic infections can guarantee the normal development of silkworms. If silkworm disease occurs during feeding, the diseased silkworm must be isolated to prevent its spread. In the case of viral silkworm disease, daily use of fresh lime powder to sterilize silkworms until the fourth day of fifth instar. Bacterial disease can be added with chlorine (red)mycin, which can achieve prevention and treatment. Stiffness can be used for antiseptic powder and water agent for silkworm body disinfection. The fly maggots are sprayed or eaten with flies. When using various kinds of pharmaceuticals, strict standards must be mastered, and must not be subject to formality.
Second, improve leaf quality
Excellent leaf quality is the material basis for ensuring silkworm body robustness and increasing calving volume. In order to maintain good autumn silkworms, in addition to doing a good job of mulberry field fertilizer management to eliminate mulberry diseases and pests in time, we must also do a good job in mining, transportation, and storage of mulberry leaves, and attach importance to handling the relationship between “acquisition†and “cultivation†so that children of all ages can Can get excellent feed.
Third, poor control of the meteorological environment
When hot and humid, the emphasis is on ventilation and humidity. Open the doors and windows, make the air convection, cover the wet grass on the roof, take a awning on the sunny side, diligently remove the sand, and use more dry materials. When the temperature is high and dry, use cool well water to moisten the interior, hang the damp cloth inside the door and window, increase the number of times to give mulberry, and add water to the leaves. When the temperature is low and high humidity, it is necessary to warm up and remove moisture. After the temperature is raised, doors and windows must be properly opened to conduct ventilation and dehumidification. Dry materials should be used more frequently to remove sand, and the amount of mulberry should be reduced to avoid accumulation of residual mulberry. When the temperature is low, the room should be warmed, and a water basin should be added to the heat source to moisten with hot water to close the doors and windows. However, attention must be paid to ventilation.
Fourth, strengthen feeding management
1. Select a small silkworm leaf to prevent the mulberry leaves from being mixed, so as not to cause the malaria development.
2, thin and full food, clever to eat water leaves. Diluted, is to achieve "a silkworm three", clever to eat water leaves, to do more than "five", "five no", that is, eat more at night, do not eat at night; eat hot and dry weather, low temperature and rainy weather do not eat ; Silkworm period to eat more, do not eat young silkworm period; eat more food, do not eat from sleep; leaf quality to eat, fresh leaves do not eat.
3, do a good deal of sleep. Pay attention to satiety and sleep, timely mention of youth in batches, strict elimination of weak and small silkworms, sleep should grasp the early partial dry negative temperature, foraging earlier than the silkworm earlier.
4, anti-poisoning. Due to the large amount of pesticides used in farmland and mulberry fields during autumn, they often cause poisoning in silkworms. We must constantly understand the use of farmland and mulberry fields and rationally arrange the use of leaves. It is best to take a small amount of mulberry leaf to try to understand whether there are residues of mulberry leaves. In case of poisoning, immediately open the window and open the window to ventilate and change the air, remove the sand by the net, feed the fresh mulberry leaves, and treat the disease according to the cause of poisoning to save the damage.
