Techniques of autumn silkworm culture

Sericulture is an ancient breeding industry in China. It is said that it originated from the wife of the Yellow Emperor, Kui Zu, and it is an important skill created by the ancient people. With the progress of society, the price of silk products is rising year by year, and the market demand for silk is also increasing. The economic benefit of sericulture is higher than that of the general breeding industry. In fact, when it comes to sericulture, we also raised it when we were very young. Autumn is the peak season for sericulture. According to data, the amount of silkworms raised in autumn accounts for about 40% of the total amount of sericulture in the whole year, so how to raise silkworms in autumn? Let's take a look at the detailed introduction of the pro-agricultural network.

1. Disinfection of silkworm room

Before sericulture, the environment around the silkworm room should be cleaned, the silkworm room must be cleaned, and the sericulture utensils should also be placed in the sun after cleaning, or they can also be soaked and disinfected with lime liquid to remove the old soil on the floor of the silkworm room. fill in a layer of pollution-free new soil, and the walls of the silkworm room are re-painted white with lime mortar. After cocoon picking, large-scale disinfection should be carried out to restrain or kill bacteria and prevent their reproduction and spread. Silkworms with disease and dysplasia should be eliminated in time, so as not to affect the whole silkworm population.

2. Select improved varieties

When sericulture is reasonable and selected in batches, autumn silkworms can be divided into early, middle and late stages according to the season, and some farmers raise 5-6 times, so that there are more times of rearing, and the silkworm rooms and utensils are all used for mixed rearing of big silkworms and small silkworms. This situation can easily lead to poor disinfection and infection of silkworms. During the outbreak of the disease, it can easily lead to the death of a large number of silkworms, resulting in a small number of broken swords and affecting economic benefits. Therefore, when raising autumn silkworms, we must raise them in batches and reasonably, usually at intervals of 12-15 days per batch.

3. Strengthen the management of mulberry

When sericulture, it is necessary to ensure the source of mulberry leaves, the consumption of mulberry leaves is huge, how the shortage of mulberry leaves will not only affect the growth of silkworms, but also affect the yield of silk, so the management of mulberry is also particularly important. For mulberry trees to loosen the soil and weed in time, timely watering when drought, timely drainage in rainy days, to ensure the vigorous growth of mulberry, and in leaf picking should also be reasonable, do not catch mulberry leaves, one-time excessive collection of mulberry leaves, resulting in mulberry dry bald. Mulberry should also do a good job of storage and transportation after collection to ensure its freshness and prevent its deterioration.

4. Disease prevention and treatment

The common diseases in sericulture in autumn are gastrointestinal abscess, rigidity, myiasis and bacterial venereal diseases, which can be disinfected with lime powder to prevent and cure the disease, while stiff powder can be used to prevent and cure this disease. Maggot disease can be treated with silkworm flies "medicine sprinkling mulberry leaves or spraying on silkworm; bacterial venereal diseases can be prevented and treated by spraying chloramphenicol 500 times on mulberry leaves.

The above is the autumn silkworm breeding technology brought by the pro-agricultural network, on how to raise the autumn silkworm content is introduced here, hope to help you, want to know more, please pay attention to the pro-agricultural network.
