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.

Co-rearing technique of young silkworms
As the saying goes, "the young silkworms are well reared for 70% of the harvest." Therefore, special attention should be paid to the co-rearing of young silkworms. (1) specific requirements and technical measures for co-rearing of young silkworms. A special small silkworm room is used in the co-breeding room. Need to heat preservation, moisturizing performance, and easy to exchange air, sericulture before strict disinfection, the implementation of "three elimination and one fumigation". two。 Heating is unified as Kang bed heating. Due to the heating of the Kang bed,

Conditions and main technical requirements for co-rearing of young silkworms
First, the purpose of co-rearing young silkworms, as the saying goes, "raise half of the young silkworms", which fully illustrates the importance of raising young silkworms. The purpose of the co-rearing of young silkworms is to enhance the physique of young silkworms to ensure the safety of large silkworms and to achieve high quality and high yield of cocoons. The advantages of small silkworm co-rearing are as follows: (1) it is beneficial to realize scientific sericulture, adopt advanced sericulture technology and facilities, promote the neat development and strong physique of young silkworms, provide guarantee for large silkworm rearing, and lay the foundation for high and stable cocoon production. (2) it is beneficial to disinfection and disease prevention. Overcome the resistance of young silkworms to adverse environment

The latest construction skills of greenhouse
Greenhouse is also called greenhouse, such as glass greenhouse, plastic greenhouse, etc. The structure of greenhouse should be sealed and insulated, but it should be convenient for ventilation and cooling. Modern greenhouse has equipment to control temperature, humidity, light and other conditions, and use computer automatic control to create the best environment for plants.

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.

Bombyx mori rearing and Disease Control
1. What problems should be paid attention to in the rearing of the third instar silkworm? The age of the third instar silkworm goes through about 96 hours, of which eating mulberry is about 72 hours and sleeping about 24 hours. The third instar silkworm is still in the young stage in physiology, its growth rate is slower than that of the first and second instar, and its body weight is 5 to 6 times higher than that of the second instar, and its adaptability to high temperature is different from that of the first and second instar. Attention should be paid to: (1) the rearing temperature of the third instar is 25.5 ℃ ~ 26 ℃, and the difference between dry and wet is 2 ℃ ~ 3 ℃. (2) mature leaves should be used for three-year-old mulberry, no

Techniques for rearing autumn silkworms
1. The characteristics of autumn silkworm period most of the mulberry cutting patterns in our city are spring fist cutting, with less spring leaves and more autumn leaves, which provides sufficient feed for the rearing of autumn silkworms. At the same time, the temperature was higher in the early stage and lower in the later stage, which was suitable for the physiological requirements of silkworm. Therefore, the root

1. New hybrid varieties of male silkworm (1) variety characters. Qiuhua × Ping 30, a new autumn male silkworm variety bred by the sericulture Research Institute of Zhejiang Academy of Agricultural Sciences, has the advantages of strong physique, uniform sleep of all ages and easy rearing. The number of ants per gram is about 2310, and the 5th instar passes through 6 days and 18 hours. After 22 and a half days, the two-day hatching rate is 49.34%, the silk length is about 1240 meters, the cocoon shape is oval, large and uniform, the cocoon color is white, and the cocoon shell rate and silk emergence rate are high. (2) key points of feeding and rearing techniques the photosensitivity of collecting ants can be properly compared with that of the general public.

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. At present, the new scientific breeding techniques have the following five points
