1, keep a good small silkworm. 1 Adhere to the small silkworm co-culture. Small silkworm communal breeding can raise the level of feeding, facilitate the unification of technical processing, unify the development schedule, save labor and save costs. 2 adjust the temperature and humidity. Small silkworms are suitable for high temperature and humid environment. Currently, most of them are multifilament varieties. In order to exert the good traits of the varieties, it is necessary to make them into three sleeps in ten days, to shorten the period of small silkworms, to extend the period of large silkworms, and to eat more mulberry silk. This period of temperature and humidity, the day of receiving ants 29 °C, dry and wet difference of 0.5 °C, 1 instar 28.5 °C, dry and wet difference 0.5 °C, 2 instar 27.5 °C, dry and wet difference of 0.5 °C, 3rd instar 25.5 °C, dry and wet difference of 0.5 - 1 °C; 3 Grasp the standard of selection: Small silkworms have a short period and fast growth rate. Once the standard of mulberry leaves is inaccurate, it is easy to cause stunting. The leaf standard is as follows: Yellow, green, yellow, 2 years old, tender green, 3rd instar, dark green; small silkworm leaves to ensure that the next slightly before the mulberry is appropriate, the second silkworm spring can also use three eyes; because three eyes age The opening is small and the maturity is uniform, which will not cause the silkworm body to be stunted, and it is beneficial to save the new shoots, facilitate the development of the mulberry and increase the yield of the mulberry leaf. 2, good mulberry satiation eat large silkworm. The mulberry protein that is eaten by silkworm in the middle of the fifth instar is mainly used for the nutrient construction of silkworm body, and the mulberry protein is mainly used to complete the synthesis of the silk material in the fifth instar late stage. The main purpose of the silkworm rearing is to obtain the silkworm; Must be well-bred, good mulberry satiety, to prevent hunger; the other 5 instar mulberry eaten large amounts of water discharged from the body of silkworm; ventilation, reduce humidity is the key to raising a good silkworm. 3, oblique noodles mulberry. This can reduce the investment in the silkworm room, save the employment of leaf collection, reduce the waste of mulberry leaves, protect the fresh leaf quality and the ventilation and ventilation of silkworm seats, and does not require the advantages of sand removal; the following points should be noted in this sericulture form: 1 When breeding small silkworms, do not pick up the top leaves and try not to pick new shoots. After the fifth instar opening, combined with summer harvest, the mulberry cultivation should be carried out (ie not raising the second spring silkworm); 2 the autumn silkworm crop should be cut before and after September 20th. Article, after cutting, the branches must retain 3-4 leaves, so that they continue to nutrition branches, cutting height is based on the height of winter cutting tip, cutting strips can not touch the top of the blade, or a bud will sprout. 4. Greenhouse sericulture: Local materials can be obtained, and due to simplicity, save investment in Jamsil, provide material guarantee for industrialization, specialization, and large-scale development of sericulture production; also improve work efficiency, easy manual control of temperature, humidity, silkworm disease Less (no pathogen accumulation), improve the quality of tannins (ventilation and ventilation, lower temperature, humidity) Adopt this form of sericulture must pay attention to a large shed should be north-south, both ends should be easy to cover and people access, easy to adjust the shed Temperature and humidity; 2 against ants, cockroaches and other infringement; 3 greenhouses should be able to drain around.
