Qianjiang, Chongqing: Young silkworms welcome co-cultivation and smart factories boost income
In early summer, mulberry leaves usher in the peak growth season. In Qianjiang District, Chongqing, the national sericulture biological industry base, the first batch of more than 10,000 mulberry silkworm seeds this year have entered the co-breeding period, relying on the intelligent co-breeding of small silkworms In factories, the co-cultivation of silkworms has become time-saving and labor-saving, and has become the “ballast stone” that leads the masses to steadily increase their income.
In Shuanglong Village, Zhuoshui Town, Qianjiang District, in the intelligent co-breeding factory of silkworms, densely packed silkworm babies are covered with silkworm foil. After two days of co-breeding period, this batch of silkworms will begin to grow under constant temperature, constant humidity, They are incubated in a sterile environment until they reach the third instar stage, and then they can be handed over to silkworm farmers to raise and form cocoons. Therefore, the co-incubation room must be guarded for a long time. With the Xiaosi Intelligent Co-breeding Factory, everything from heating, dehumidification to ventilation and lighting can be controlled by a set of intelligent control systems.
“This set of equipment realizes the intelligent co-breeding of silkworms. For example, if there is any abnormality in the temperature and humidity of the co-breeding room, the system will automatically alarm and adjust to the most appropriate state.” Qianjiang District Sericulture Sun Zebo, the company’s deputy manager, told reporters, “When it’s time to ventilate, the ventilation fan will be turned on so that the environment in the co-breeding room is always suitable for the growth and development of baby silkworms.”
As the saying goes, “If you raise silkworms well, you will get 70% of the harvest.” In Qianjiang District, co-breeding of small silkworms used to rely on co-breeding households to do it alone. Once disease occurs, it will directly affect the income of sericulture. Starting from 2021, the local government will pilot smart co-breeding factories for small silkworms in qualified towns and villages to ensure the neat development of silkworms and improve the success rate of co-breeding. It can save 8 to 10 days of silkworm rearing time every season. Zhuoshui Town, Qianjiang District alone More than 170 sericulture farmers have benefited from this.
“Our town has more than 7,000 acres of mulberry gardens. There used to be more than 20 co-breeding rooms, which were basically artificial co-breeding. The cost of raising a single silkworm is more than 40 yuan, and there are risks.” According to Zeng Xiangbo, mayor of the Zhuoshui Town Government in Qianjiang District, “After the intelligent silkworm co-breeding factory was built, we saved at least 10 yuan by raising a single silkworm, and the scale of single co-breeding increased from 80 to 80. 5 times, to about 400 now.”
Sun Zebo, deputy manager of the Qianjiang District Sericulture Company, told reporters, “At present, this intelligent silkworm co-breeding factory can breed 1,600 silkworms every year, which is equivalent to the co-breeding scale of the previous five co-breeding rooms. Silkworms are bred together here, which is conducive to the unified prevention and control of silkworm diseases and centralized guidance of technology, which greatly saves production costs.”
It is understood that Qianjiang District has successively built 8 intelligent co-breeding factories for small silkworms, and has taken the lead in realizing industrial operation in Wuling Mountain. Co-bred silkworms account for about 10% of the number of seeds produced throughout the year. The local area will rely on the Xiaosi Intelligent Co-breeding Factory to continue to promote the intensive and large-scale development of the sericulture industry and help rural revitalization.
