How to promote the development of silkworms

The development of silkworms is easy for feeding and management, and the silkworm body is also robust. To achieve this goal, we must grasp the following points. The day before the caterpillar fung sing, the common breeding room should be warmed to 38°C and the wet and dry difference should be 2-3°C. After returning the silkworm species, they are evenly spread evenly on the silkworm seat paper, and the room temperature is raised to 43°C, and the wet-dry difference is 1-2°C. The use of coal briquettes to heat the silkworm room, pay attention to doing a good job of ventilation. In addition, silkworms must be strictly shading, so that the development of embryos. If silkworm eggs turn green more homogeneous, then the next morning can be sensitive to ants, otherwise it is appropriate to receive the ants in the early morning of the third day. When receiving ants at a timely time, if the ant is too early, some silkworms will not have appetite at the time of receiving the ants, which will cause the silkworms to eat mulberries first. If you receive the ant when you receive it, it will cause the development of malaria. The optimum time for receiving ants should be 2-3 hours after the eggs are hatched. Most of the ants have appetite and start to feed. Spring silkworms generally accept ants at 8 to 9 am and strive to end the ants before 10:00. If the uncovered silkworm eggs are found in the collected ants, they should continue to be protected in the dark place, and the ants should receive the light again the next morning. Controlling the head density of silkworms, such as the uneven density of silkworms, can lead to uneven development of silkworms. Therefore, each time before giving mulberry, it should be expanded and evenly distributed. It is required that small silkworms should not touch silkworms with silkworms, and silkworms should not overlap with silkworms. It is appropriate. Avoid the use of different leaves in order to promote the development of young silkworm silkworm, in accordance with the silkworm leaves of various ages standard mining leaf feeding silkworm, to avoid tender and old mulberry leaves fed silkworm. In addition, give Sang even thickness. Bombyx mori is uniformly heated in different locations of the silkworm cocoon in different locations within the silkworm cocoon, and is affected by temperature differently. For example, the temperature at the upper part of the silkworm shelf and near to the fire source is high, and the cotyledons develop rapidly; on the contrary, the temperature is low, and the cotyledon develops slowly. . Therefore, attention should be paid to relocate the cocoon often, and the minimum cocoon period should be changed at least once a day. Feeding at a proper time to feed prematurely, some silkworms have no appetite, and even some parts of the silkworm have been repelled, resulting in uneven development when the same batch of food is eaten and eaten. Therefore, timely feeding is needed. Before going to sleep, if the silkworms are not fully developed, the time for feeding after sleep can be reduced by about 3 hours compared with normal feeding. This can ensure that the slow-growing silkworms and the faster-growing silkworms eat the leaves at the same time. In addition to the net addition, after two batches of general sleep, after giving two mulberries, it is still not able to sleep and can be added to the net. The proposed blue head should be placed near the heat source, and the large silkworm head can be placed on the upper shelf of the silkworm frame. Individual stunted, weak physical silkworm should be eliminated.
