In the minds of ancient Westerners, China was a "mysterious treasure trove of the East." It is recorded that around the 8th century BC, the ancient Greeks knew about China, all thanks to our specialty , silk. Silk is a commodity invented and mass-produced by the working people in ancient China, and it opened the first large-scale trade exchange between the East and the West in the history of the world, known as the "Silk Road".

The history of silkworm reeling in China is very long, and legend has it that the Yellow Emperor's wife, Changzu, invented the method of cultivating mulberry silkworms. According to archaeological findings and historical records, China began to raise silkworms before the Xia Dynasty, the Shang Dynasty also specially set up an official position responsible for mulberry silkworms "female silkworms", the Zhou Dynasty also developed into a "pro-silkworm" system, tianzi and princes have "Gongsang Silkworm Room", the development of Nongsang during the Spring and Autumn warring states period has become an important national policy for rich countries and strong people. Successive rulers of successive dynasties have attached great importance to nongsang, and the sericulture technology has been continuously improved and updated, and the sericulture technology has been elaborated in ancient agricultural books such as "Nongsang Jijiao", "Shi Nong Must Use", "Qi Min Zhi Shu" and so on.
According to records, the constant temperature rearing of small silkworms appeared in China in the late 3rd century AD, indicating that there was already a certain understanding of the relationship between the growth and temperature of silkworms at that time. In the subsequent breeding process, the ecological impact of mulberry, fire, cold, summer, dryness, wet and other factors on the growth of silkworms was gradually noted, and the sericulture technology became more and more perfect.
Traditional sericultures generally need to use ground fire cages or coal brick stoves to raise the temperature, and control the temperature and humidity through manual sprinklers. This method is all based on experience, for people with slightly less experience, it is difficult to accurately control the temperature and humidity in the silkworm room, which can easily lead to a sudden rise and fall in temperature and humidity, while the harmful gases such as sulfur dioxide and carbon monoxide produced by burning coal not only affect the ecological environment, but also directly affect the development and growth of silkworms, resulting in low yields and low quality of cocoons.
In addition, the traditional sericulture method requires a lot of manpower, and the technical requirements for sericulture farmers are relatively high, far behind the large-scale and intensive needs of the modern sericulture industry.
Traditional silkworm co-breeding room
In order to solve the drawbacks of traditional sericulture methods, the scientific research unit headed by the Institute of Sericulture of Sichuan Academy of Agricultural Sciences has developed an intelligent control system for the co-breeding environment of small silkworms, which has made a new development in China's sericulture technology.
The intelligent control system of the small silkworm co-breeding environment is mainly composed of control box, heating plate, ultrasonic humidifier (including moisture pipe network), air conditioning, ventilation fan, etc., and automatically controls the co-breeding room heating, cooling, humidification, dehumidification, ventilation, uniform wind, disinfection and lighting through the control box, with automatic control and timely display functions.

Through the intelligent control technology of the small silkworm co-breeding environment, the temperature, humidity, air, etc. in the sericulture co-breeding room are scientifically intelligently controlled, so that the efficiency of sericulture is higher, the feeding amount is greater, and the small silkworms obtained from co-breeding are well developed, the silkworm cephalopods, and the silkworm physique is strong. At the same time, the environmental technology of small silkworm co-breeding also supports remote management, and environmental parameters can achieve multi-platform operation, making sericulture more intelligent and convenient.

From 2010 to 2021, the research results of intelligent control technology for small silkworm co-breeding environment have been applied and promoted in more than 40 counties (cities) and more than 20 cocoon silk leading enterprises in Cuba, Vietnam and other countries and Chongqing, Guangxi, Yunnan, Guizhou, Henan, Shaanxi, Shandong, Gansu, Sichuan and other places in China. By the end of 2020, the intelligent control system and its auxiliary equipment for the co-breeding environment of small silkworms have been promoted more than 3,000 sets, with sales of 11.775 billion yuan and new profits of 2.355 billion yuan, achieving significant social, economic and ecological benefits.

The intelligent control technology of the co-breeding environment of small silkworms provides technical and equipment support for the adjustment of China's "east-to-west" industrial structure. This technology has transformed the development mode of sericulture industry, so that the traditional sericulture industry has embarked on the road of intelligence, scale and intensification, at the same time, due to the reduction of the technical difficulty of sericulture, the intelligent control technology of the small silkworm co-breeding environment has promoted the local employment of farmers and the return of migrant workers to start a business, and has contributed to the implementation of China's precision poverty alleviation and rural revitalization strategy.
