1. Choose good breeds. Adoption can be adapted to adverse environments such as high temperature and dryness, and it is suitable for hybrids used in early autumn. In places where the raising level is relatively high, spring varieties such as "56" and "A four yuan" can be cultivated in the autumn silkworm stage, which will help improve the quality of silk and increase profits.
2. Disinfection and disease prevention. Before silkworm rearing, sericulture, and silkworm rearing, drying, and disinfection, to eliminate pathogen infection and control the damage of silkworm diseases, it is the key to raising good silkworms. Special attention should be paid to the following: Cleanliness should be fine, pieces are not everywhere. Missing. Disinfection must be strict, master standards, and strict and thorough. Prevent disease, work hard, use small silkworms, use "small silkworm disease prevention number one" or one-time anti-stuck powder for each age, use "large silkworm disease prevention number one", or prevent powder 1 time, 1 time with fresh lime powder. Chloramphenicol is used once in the third instar, two to three times in the fourth instar, and three times in the fifth instar; the “silkworm flies†is used once in four instars and in the fifth instar in two or three times. In addition, silkworms that are not in use should be frequently exposed to sunlight.
3. Control temperature and humidity. When it encounters high temperature and dryness, the roof of the silkworm room is covered with white or covered grass, and a pergola is placed outdoors. The well is sprayed with water on the outdoor walls and indoor curtains, and the pots and cylinders filled with well water are placed in the room to cool and moisten the water. At noon high temperatures, a fan can be used to promote smooth air in the silkworm chamber, and at the same time spray water on the silkworm leaves to feed the silkworms.
In case of autumn rain, low temperature and humidity, the silkworm room to be heated and dehumidified, silkworm use more lime, eschar and other dry materials, multi-purpose anti-static powder, increase the number of sand removal.
4. Strengthen the management of mulberry fields and improve leaf quality. To cultivate good silkworms, small silkworm co-culture should be organized. Select a piece of land with fertile soil, convenient irrigation and drainage, air and light transmission, and good growth in the mulberry field, and use it as a small mulberry special mulberry garden. Silkworms use mulberry gardens. Every time they raise the silkworms for 1 time, they must apply 1 long leaf fertilizer. It is best to apply some organic fertilizer. At the same time, we must do a good job in weeding, pest control, irrigation and drainage in the mulberry fields to promote more, bigger, thicker and better autumn leaves.
5. Do a good job in harvesting, transporting and storing autumn leaves. To take autumn leaves, we must pay attention to the percentage of take-out. Early autumn silkworm from the fourth age from the base of the branches from the bottom up leaves, the amount of extraction is not more than half of the branches and leaves is appropriate; mid-autumn silkworm leaves, the tip to stay at least 7 to 8 leaves; see autumn leaves silkworm rearing. After the silkworm rearing, leaves at least 5 to 6 leaves on the shoots to accumulate nutrients in the mulberry trees for early germination and germination of the spring leaves next year. Second, we must pay attention to picking leaves and keeping the stems, and not cutting the leaves, so as not to damage the axillary buds, affecting the yield of Mulberry leaves in the next spring. Third, we must pay attention to the selection of small silkworms suitable for ripening young leaves, large silkworms in the morning to take more water leaves, the night with leaf picking late harvest, the sun does not collect leaves.
The harvested mulberry leaves must be loaded and shipped. The returned mulberry leaves should be stored in a cool, humid, and unventilated place. During the process of harvesting, transporting and storing mulberry leaves, prevent mulberry leaves from drying out, heat, and deterioration.
6. Strengthen feeding management. Keep a good autumn silkworm to do: 1 early photosensitivity, receiving ants. At 4 o'clock in the morning, the ants received the end of the ants before 8 o'clock to prevent the ants from being famined and frail. Small silkworms expand their seats in advance, and large silkworms strive to achieve two thin slivers. Autumn silkworm feeding leaves the best thin feeding, high temperature and dry weather should be less during the day to give more at night. Nourish fresh water at noon, and feed more moist leaves.
Autumn silkworm difficult to raise attention
In the spring, summer and autumn seasons, it is difficult to raise silkworms in the autumn, because, after the spring and summer, even the autumn silkworms are susceptible to silkworm disease, and the weather is changeable or meets the “Autumn Tigersâ€, which are dry at high temperatures, or encounter typhoons and autumn rains. The poor quality of autumn leaves leaves the autumn silkworms with low yields, poor quality, and low yields. So, how can we cultivate good autumn silkworms?
