Pay attention to these few issues when raising silkworms, and success is more likely

As everyone knows, the conditions for raising silkworms in rural areas are not very good. Many silkworm-raising villages and hamlets have unpaved roads, which brings many disadvantages. Secondly, there are no cooling or heating facilities, so rural silkworm raising is very vulnerable to severe weather. Although the conditions for raising silkworms in rural areas are poor, in the process of raising silkworms, as long as farmers pay attention to the following few issues, success in raising silkworms is then hopeful.

1. Apply more organic fertilizer to the mulberry field

In the mulberry field, in addition to applying nitrogen, phosphorus and potassium chemical fertilizers, more organic fertilizer should also be applied, such as chicken, duck, pig and cow manure, pond mud, biogas residue, human feces and urine, bran fertilizer, etc., and the application amount should be more than 200 kg per mu. If only chemical fertilizers are applied in the mulberry field, although the mulberry trees grow faster, the quality of the mulberry leaves is not good. After silkworms eat such mulberry leaves, they tend to become puffy, and both the yield and quality of the silkworm cocoons are not high. More importantly, the disease resistance of the silkworm body is poor, and it is very easy for grasserie or bacterial silkworm diseases to break out. Therefore, more organic fertilizer should be applied in the mulberry field, which can improve the quality of mulberry leaves, enhance the stress resistance and disease resistance of silkworms, and ultimately increase the yield and quality of silkworm cocoons.

2. Disinfection of the environment and silkworm room before and after raising silkworms

1. Many farmers who have just started raising silkworms should pay more attention to this aspect. Some of them do not understand the importance of disinfection, and some do not know what drugs to use or how to carry out disinfection, so the disinfection of new silkworm households is generally not done thoroughly, and in their silkworm raising, generally the first two batches are still acceptable, but as pathogens accumulate in the silkworm room, after the third batch there is often a major outbreak of grasserie, and the silkworm raising yields nothing. So the importance of disinfection work needs no further explanation.

2. Before disinfection, the silkworm trays, plastic film, silkworm nets and other tools in the silkworm room should first be moved out, and the silkworm room and the surrounding environment should all be cleaned up. The drugs used for disinfection are generally bleaching powder with a concentration of 25% (add 24 kg of water per kg of bleaching powder) or sodium hypochlorite solution (add 20~30 kg of water per kg of the drug). During disinfection, the floor, walls and ceiling in the silkworm room, as well as the surrounding environment, should all be sprayed until wet through. The standard is that they can remain wet through for more than half an hour, so as to achieve the disinfecting and sterilizing effect. After the silkworm room is disinfected, the doors and windows should be closed immediately and kept sealed for half a day, which helps improve the disinfection effect.

3. Disinfection of tools such as silkworm trays and mountages should be done by building a disinfection pool for soaking. The disinfection pool should be wide and large enough, generally able to hold one mountage or one silkworm tray. After filling the disinfection pool with water, measure the water before adding the drug, so as to ensure the concentration of the disinfectant solution. During disinfection, first soak relatively clean tools such as plastic film, silkworm nets and leaf-collecting baskets, and then soak the silkworm trays and mountages. The soaking time is more than 5 minutes for silkworm trays and more than 3 minutes for mountages. If silkworms are raised on the ground, the bricks used as foot pads on the ground should also be soaked. After all tools are soaked, they should be put into the disinfected silkworm room and kept sealed to improve the disinfection effect.

3. Protection of the broader environment for raising silkworms

1. In raising silkworms, in addition to protecting one's own silkworm room and the surrounding environment, protection of the broader environment is also very important, especially for specialized villages where the whole village raises silkworms. If the broader environment is contaminated by viruses, it may contaminate the mulberry field and silkworm room through the activities of people and livestock, affecting the success or failure of silkworm raising. The broader environment mainly refers to the roads, ditches, ponds, rivers, grass clumps, etc. in the village, and its scope is relatively wide. Once contaminated, disinfection is very difficult to carry out thoroughly, so the broader environment can only be mainly protected.

2. To protect the broader environment, first of all, silkworm litter must be managed well. Silkworm litter should be piled up in a centralized place, and at the same time care should be taken not to let chickens, ducks, pigs and dogs root and turn it over randomly. After silkworm raising is finished, the silkworm litter should be composted and then transported to places far away from the silkworm area for use. Silkworm litter must absolutely not be applied in mulberry fields or in fields near mulberry fields. Secondly, dead and diseased silkworms during the silkworm raising process must absolutely not be thrown away randomly, and should be deeply buried or treated together with silkworm litter. Finally, undisinfected silkworm trays and mountages must not be washed with water or taken to ponds or small rivers for cleaning, otherwise the virus-containing sewage will flow everywhere and cause repeated contamination.

4. Observe carefully during the silkworm raising process

Careful observation during the silkworm raising process can have the following benefits:

1. The amount of mulberry leaves given can be adjusted according to the remaining mulberry leaves. If a lot of mulberry leaves remain, it means too much was fed last time, and this time a little less can be fed than last time; if the mulberry leaves have been eaten completely bare, it means too little was fed last time, and this time a little more should be added.

2. If the silkworms have any abnormality, you can know it at the first moment, analyze the cause in time, and solve the problem in time. For example, if silkworms suffer poisoning or grasserie, if you can discover it early, you can take measures to control it before the poisoning deepens and the grasserie spreads over a large area, avoiding greater losses; on the contrary, if it is discovered too late, then there is no way to save the situation. Therefore, careful observation of silkworms is very important. Generally, observation should be carried out before each feeding of silkworms, when there are fewer mulberry leaves, which is helpful for observation.

Alright, the above is what the Tuliu.com editor has brought to everyone about what needs attention when raising silkworms. I hope it is helpful to everyone. Then see you next time.
