First, disinfection and disease prevention: This job requires more stringent than the spring silkworm, to do a good job of Mulberry's disinfection work to prevent cross-infection of silkworm diseases. Second, the selection of mulberry leaves: silkworm leaf standards are generally based on the leaf position of the leaf color as the main basis, the leaf color than the green leaf surface of the first 3 to 4 leaves for the 1st leaf; leaf color is green 4th to 5th leaf It is a 2 years old leaf; The 5th to 7th leaves whose dark green leaf touches slightly hard touch are 3rd age use leaves. The harvesting is mainly based on early harvesting, that is, when the dew does not dry in the morning, about 70% of the leaf volume for the whole day is picked, and 30% can be picked in the evening. The harvested leaves must be transported along with transport, loosely packed and transported, not pressed, stacked, blown, or sun-dried to prevent the mulberry leaves from drying out. The storage room should be kept dark and damp, and the storage room should be kept clean. Third, heat preservation and moisturizing: the temperature in the late autumn silkworm is relatively low, and the rearing period for the small silkworm period should not be lower than 26°C. The large silkworm stage often encounters low temperatures, while the fourth instar silkworm has weak resistance to low temperature, so it is necessary to change the temperature of the silkworm stage without heating. The habits are to be maintained at a proper temperature. The 5th instar will maintain the temperature of 23°C to 24°C. When the humidity is high, the temperature will be increased and humidity will be released, and the humidity will be increased by warming and moistening, which will promote the healthy development of the silkworm. Fourth, feeding and management: 1, thin enough to eat. To achieve a silkworm three, high humidity at noon, eaten Sangwangsheng, should increase the supply of mulberry or to mulberry, and clever to the wet leaves, at night or in rainy days to give mulberry or not to wet leaves, so that children can eat enough to eat silkworms . 2, in the children's silkworm to sleep when they must promptly mention the green batch, so that eating satiety to sleep, sleep in the right temperature and humidity, eating mulberry leaves to be fresh, and to grasp the appropriate cooked partial tender. 3, Shangyu can use outdoor camping technology, so that the appropriate cooked batch, thin, and for the situation at the time, to do the appropriate temperature, humidity, ventilation and ventilation work, to prevent the occurrence of non-cassia.
