The general high temperature and humidity in autumn are not suitable for the growth and development of silkworms, and the leafy quality of mulberry leaves is poor. In addition, the pathogens accumulated in spring and summer are more and the pathogenicity is stronger. Therefore, autumn silkworm is more difficult to breed and susceptible to disease. , Low leaflet production, poor quality. Only by strengthening management and doing a good job in disinfection and disease prevention can we harvest the harvest of the autumn silkworm. The main points of its feeding and management are summarized as "three defenses," "three elections," "three times," "three early," and "three thin." (a) The three defenses are prevention of silkworm disease, prevention of hunger, and prevention of sultry heat. 1. Autumn silkworm disease susceptible to the occurrence of mid-enteritis pyogenic disease, viral softening disease. Disinfectant drugs are mainly fresh lime, bleach, and formalin. Conscientiously do a good job before, during and after the sericulture to prevent disease disinfection work, disinfection and disease prevention throughout the entire process of sericulture. 2. Anti-hungry autumn outside temperature of up to 38 °C, indoor temperature of 32 °C, silkworm food consumption was significantly reduced, easily hunger, should take cooling measures. When daytime temperatures are high, drugs such as chloramphenicol and gemectin are added to feed leaves, and water is not added to water. Generally, this measure is adopted during the period of large silkworms, which can reduce the temperature of the small environment while maintaining Mulberry fresh. When the temperature is high during the day, feed thin meals and give them more at night. 3. The anti-swelling heat is highlighted in the silkworm period to prevent stifling heat, the silkworm room must have a convection window, open the window or use a ventilation fan to promote indoor air flow. Shading before opening the window can reduce the adverse effects of high temperature and heat on the silkworm. (B) Three elections are selected silkworm species, selected silkworm house, selected mulberry leaf 1. The temperature of selected silkworm eggs in autumn is high, and silkworm varieties that are resistant to heat and disease should be selected. 2. Select silkworm room. In order to reduce the adverse effects of high temperature and sultry in autumn on silkworms, we must choose a relatively spacious and silky room with a cool, mobile window and ventilation. 3. Select mulberry leaves. For small silkworms and all ages, mulberry must be selected carefully according to the leaf standard, and the leaves must be ripe and tender. For the contaminated leaves, pests and leaves must be rinsed with clean water or 0.3% bleach and then fed with silkworms. . (c) Sanqin works on feeding silkworms, diligently expands seats, and diligently removes sand. Feeding silkworms frequently has high temperatures in the autumn, and mulberry leaves are prone to loss of water, which, together with the reduction in the amount of food consumed, can easily cause mulberry leaves to be wasted and silkworms become hungry. In order to make the silkworm mulberry satiety, it is necessary to feed thinly, so it is possible to feed the silkworm with the leaves and eat it before feeding. 2. Due to the high temperature, silkworms develop rapidly. To prevent close feeding, let silkworms sorghum eat well and develop neatly. Based on the principle of first expanding and lengthening, expand the sorghum tree and then give mulberry. 3. Because of the high temperature, the silkworm sand in the silkworm seat is prone to steam and heat, and the pathogenic bacteria multiply quickly. Diligent silkworm excrement can create a suitable environment for the growth and development of silkworms, reduce the damage of steaming heat to silkworms, and reduce the incidence of silkworms. . (d) Early receipt of ants as early as possible, early foraging, early mentioning of youth. In autumn, the temperature is high, and the energy consumption of silkworms is large. If the ants are foraging, foraging, or mentioning young, the silkworm crawls everywhere for food, and it is prone to hunger and fatigue. Autumn silkworm ants should be carried out at 7-8 am. Foraging is best performed when the head of the silkworm becomes brown. Generally, 95% of the silkworms of the same batch of silkworms are bred after feeding. 85% of the silkworms were sprinkled with fresh lime powder and gave a few leaves. (v) Three thin and thin silkworms are thin, silkworm cocoons are thin, and silkworm heads are thin. Silkworms are thin and silkworm cocoons are used for ventilation and ventilation to reduce the adverse effects of high-temperature and sultry heat on silkworms, increase the food intake of silkworms, increase their fitness, and increase disease resistance. Silkworm heads are thin, and the area of ​​each type of silkworm is 45 square meters. If the silkworm head is too dense, one will eat up the sambucus, causing silkworms to be unevenly developed, affecting the amount of cocoon production and pupa; second, the temperature and humidity of silkworms. Increased, silkworm microclimate is bad, affect the silkworm physique; Third, the silkworm's foot scratches each other's skin, easy to infect blood type pus.
