How to prevent the occurrence of young silkworms and lost silkworms and increase the yield of silkworms?
The cocoon yield is not only related to the weight of single cocoon, but also largely depends on the number of larvae and lost silkworms, so it is an effective measure to prevent the occurrence of young silkworms and lost silkworms in the process of rearing. Reasonable temperature and humidity should be kept at a reasonable temperature during the period of young silkworms.

Cutting leaves to feed silkworms to seek advantages and avoid disadvantages
The young silkworm stage (1-3 instar) is a critical period for sericulture production. Only careful feeding and scientific management can lay a good foundation for disease-free and high yield in the later stage. In the production of sericulture in rural areas, some silkworm farmers are afraid of trouble and save trouble, and the whole leaves are still used to feed silkworms in the young silkworm stage, resulting in uneven development of young silkworms and serious waste of mulberry leaves. (1) to avoid the loss of the head of the small silkworm, especially the whole leaves of the 1st instar silkworms, the remaining mulberry that has not been eaten by the silkworms often shrinks and curls into a tube, wrapping part of the silkworms among them, while the young silkworms move.

New technology of rearing silkworm scientifically
The silkworm, Bombyx mori, is a completely metamorphosed silk-spinning insect among the thermophilic animals. After four times of sleep and five instar periods of 26-28 days, the larvae ate more than 20 grams of mulberry leaves to mature silk cocoon, the cocoon was white, the weight was about 1.8-2.3g, the cocoon shell rate was 20-23%, the silk length was 1000-1400 meters, and the silk diameter was 2.63.2 points. Usually, there are 1.8-20000 silkworms in a piece of silkworm eggs, which need 50,600kg mulberry leaves and can produce 30-40kg silkworms.

How to prevent the occurrence of young silkworm, Vosangyi silkworm and lost silkworm
The cocoon yield is not only related to the single cocoon weight, but also largely depends on the number of seeds, so effective measures should be taken to prevent the occurrence of young silkworms, mulberry silkworms and lost silkworms. The specific measures are as follows: first, select good leaves to collect ants and 1-year-old and 2-year-old silkworm leaves, to choose mulberry leaves with suitable maturity and tender, fresh leaves, moisture content of not less than 75%, avoid using old leaves and immature leaves, otherwise it is easy to form young silkworms. We should also choose fresh and tender mulberry leaves to feed silkworms during the mid-feeding period and high-eating period. 2. suitable temperature and humidity the optimum room temperature of the 2nd instar silkworm.

How do silkworms spit out flat silk
Flat silk can be directly processed into calligraphy and painting silk paper, silk stickers, silk quilts and a variety of handicrafts, which can get a better price than ordinary silk products.

Ten ways to prevent silkworm disease
1. Look at population development. When collecting ants, the hatching is uneven, the size of the silkworm is uneven, the head is big and the tail is small, and there is much silk spinning, crawling around the silkworm seat, indicating that the body is weak. In the process of feeding, touch the silkworm with the hand or lift the silkworm, such as the silkworm contraction, the resistant silkworm is the healthy silkworm, which shows physical weakness without feeling. Big silkworm period, touch the silkworm with the back of the hand, feel cold for the healthy silkworm, have a sense of dampness and heat, indicating that the physique is not strong. two。 Look at the posture before and after molting. When the healthy silkworm molts, its head and chest are held high and the skin is molted together. If you stay awake for a long time, you will fall asleep later.

A New method of efficient feeding and rearing of Silkworm, Bombyx mori
In the period of big silkworm, especially the fifth instar silkworm, the amount of mulberry used accounts for about 85% of the whole age, and a large number of workers such as removing sand, giving mulberry and catching mature silkworms are concentrated in the fifth instar. According to the survey, the traditional silkworm foil sericulture. Not only the amount of work is large, but also the sericulturists are very hard, and the labor efficiency is low. The use of large silkworm fixed silkworm platform rearing and automatic silkworm feeding, no sand removal, no mature silkworm catch, no upper and lower end foil, convenient for mulberry and shedding. Compared with the traditional silkworm foil rearing, it can save labor by more than 50% and reduce labor intensity by 40% and 50%. I.

How to identify the health of big silkworms
First, when sniffing into the silkworm room, smell the smell of the silkworm room. If the silkworm room has only the fresh smell of mulberry leaves, but no other peculiar smell, it shows that the silkworm is disease-free. Second, after listening to mulberry with your ears, if you hear the sound of silkworms eating mulberry like a light rain, it shows that the big silkworms are healthy. Third, observe the body color of silkworms with your eyes, and the body color of healthy silkworms is generally blue and white. The skin of eating silkworms is tense and shiny, and the action is lively, raising the head and chest at rest; the dorsal vascular segment beats rhythmically; the population develops in the same size; feces have a certain shape (except mature silkworms).

Benefits of co-rearing young silkworms
Silkworms generally go through 4 sleep and 5 years old from hatching to cocooning. The 1st and 3rd instar is called small silkworm, and the 4th and 5th instar is called big silkworm or strong silkworm. The young silkworm period is the period of enriching the physique and the foundation of the whole silkworm period. The young silkworms are well reared and the silkworm body is strong, which can enhance the resistance to adverse environment and pathogens in the big silkworm stage. It is conducive to a bumper cocoon harvest. Therefore, raising young silkworms is the key to a bumper cocoon harvest. (1) it is convenient to carry out scientific sericulture: the juvenile silkworm requires higher temperature and humidity, and there must be a special person to adjust the temperature and humidity day and night.

Measures to prevent the occurrence of three-sleeping silkworms
At present, most silkworms reared in our province are four-dormant silkworms. Under normal green and feeding conditions, four-sleeping silkworms should sleep four times in a generation. However, if the rearing conditions are bad, the silkworms may sleep only three times in a generation, resulting in less mulberry consumption, smaller cocoon shape and lower yield. The reasons why silkworms sleep only three times are as follows: green under low temperature, dry and dark conditions of about 20 ℃, receiving light for more than 12 hours in a day, feeding mulberry leaves with tender or high protein content, and straight silkworm eggs without heating protection.
