The Function and Main Techniques of Silkworm Rearing
The sericulture is the only way for the regionalization and large-scale production of sericulture, a technical innovation for sericulture production, and a technological revolution adapted to the industrialization of sericulture in our city. Shed sericulture is of great significance to the promotion of traditional production of sericulture. First, the role of greenhouse sericulture Silkworm sericulture is conducive to promoting the scale of sericulture, industrialization, to solve the tension in the silkworm chamber, so that the separation of human and room to adapt to the scale of operation; greenhouse sericulture is conducive to thorough disinfection and disease prevention, reduce silkworm disease; greenhouses Silkworm rearing is conducive to raising the yield of silkworm cocoons, the ventilation performance of silkworm rearing is good, the area of ​​large silkworm silkworms is guaranteed, and the large silkworms can be eaten and eaten satisfactorily. Generally, each strain of silkworm can increase its production by about 10%; Ventilation conditions are better than those in the room. The speed of humidity removal is fast and the humidity is small. It is beneficial to improve the quality indicators such as the silkworm cocoon unwinding rate. Greenhouse sericulture is conducive to sericulture and labor-saving, silkworm sericulture labor-saving, and silkworm mulberry breeding , silkworm rearing, little rearing, and rearing are simple and convenient. In the fifth instar period, sand removal is not needed every day. Spring silkworm mulberry breeding generally saves 50% of labor, and each silkworm species can save 8 to 10, saving 80% of sericulture equipment. Greenhouses can be used in a comprehensive manner. Winter season can be used for off-season vegetable production, nursery, and production of edible fungi or poultry breeding. In winter, vegetables grown in greenhouses have a good income increase effect; sericulture sheds have a relatively low cost and can be used to increase efficiency. Use, galvanized steel tube greenhouses 160 square meters of direct construction costs around 3,600 yuan, 20 yuan per square meter, generally used 5 times a year (silkworm, vegetables), can be repeated for many years, is conducive to the promotion of demonstration. Third, the main techniques for sericulture in greenhouses Strict-raising techniques in greenhouses and indoor conventional breeding techniques vary due to changes in the environment. Based on conventional indoor breeding techniques, the following technical measures should be emphasized: Strict disinfection and prevention, and daily It is best to sprinkle fresh lime once to keep the silkworms dry, and at the same time do the fly control work; remove the silkworms, spread a layer of fresh lime on the ground, lay a layer of straw or a layer of film, and develop the same degree of silkworms when removing silkworms. The silkworms are put together so that they can be managed in the future. The density of silkworm heads should be dilute properly; timely access to sheds, generally small silkworms (1-3 years old) for co-culture, 4th instars or 5th instars for the second day into sheds, such as foraging Into the shed, due to silkworm's poor resistance to the environment will affect the physical fitness of silkworm, 4 years old into the shed, can also be put silkworm Taiwan or silkworm cocoon feeding; temperature and humidity control, greenhouse temperature control of silkworm rearing is focused on doing a good job On the basis of cooling, strengthen ventilation, covering the shade net, eating wet leaves, using the roof to cool, wet in the rainy season; flexible to the mulberry, the time interval during the day to give a small amount of mulberry can be appropriately reduced, long time interval can be increased appropriately To make silkworm full Eat a good food; on the clusters of light, when the mature silkworm on the cluster to pay attention to shading, to prevent the occurrence of scabs and so on.
