Wusheng, Sichuan: Electrification of the sericulture industry creates a beautiful countryside
Wusheng County is a major cocoon-producing county in Sichuan Province. In recent years, it has adopted the development model of “agricultural park + leading enterprise + cooperative + farm + farmer”, with the sericulture industry as the leading industry. Wusheng County Power Supply Company renovated and upgraded the rural power grid and arranged for Taiwan district managers to provide “power housekeeper” services to promote the development of the electrified sericulture industry and help farmers increase their income.
On February 20, in the 10,000-acre mulberry garden in Menshan Township, Wusheng County, Sichuan Province, mulberry trees planted in succession have sprouted buds. In the sericulture greenhouse not far away, Yang Junwei, a major sericulture farmer, poured the freshly picked mulberry leaves into the mulberry cutting machine. He pressed the start button, and the mulberry leaves were washed, chopped, and evenly spread on the silkworm bed. Tens of thousands of white and fat silkworm babies kept squirming and happily enjoying their “big meal”.
Wusheng County is a high-quality sericulture production area in China. It has formed a full industrial chain of mulberry planting, silkworm rearing, cocoon harvesting, silk reeling, silk weaving, and sales. Cocoons, silk, silk and other products are exported to Japan, South Korea, Italy, The United States and other countries and regions. Wusheng County Power Supply Company provides a full range of power supply services for the sericulture industry and helps the industry develop rapidly.
Guaranteeing water and electricity for irrigation helps expand planting scale
“If you plant a field of mulberry, you can save your family from drought.” Winter and early spring are good times for planting mulberry and growing seedlings. After the Spring Festival, mulberry farmers began to be busy in the mulberry gardens, replanting mulberry trees, straightening, cultivating, fertilizing and irrigating the mulberry seedlings.
“In the past, watering the roots of mulberry trees had to be carried on one’s shoulders. Now, watering and fertilizing have been electrified.” Watching the drip irrigation pipes evenly deliver the thin water flow to the roots of the mulberry trees, Mengshan Township opened up Jiang Anping, a farmer in Kou Village, said.
In 2019, Wusheng County introduced a number of support policies for base construction, labor employment, finance and insurance, etc., expanded diversified business channels such as mulberry and mulberry branch cultivation, silkworm pupae, and understory breeding, and guided villagers to plant mulberry and raise silkworms.
In June 2019, Jiang Anping, who had been working abroad, returned to his hometown and transferred more than 600 acres of land to plant mulberry trees, installed drip irrigation facilities in the mulberry garden, and bought rail transport vehicles to transport mulberry leaves and fertilizers. At that time, there were only 4 transformers in Changkou Village, supplying power to 449 households.
In order to meet the electricity demand for mulberry planting, Wusheng County Power Supply Company has launched rural network transformation and upgrading projects in batches since 2020. A total of 463.83 kilometers of 10-kilovolt lines and 2,945.83 kilometers of low-voltage lines have been newly built and renovated. The installation and Increase the capacity of 780 10-kilovolt distribution transformers with a capacity of 84,400 kVA.
“It used to take more than 20 people to water 600 acres of land for two days; now, you only need to press the switch and it can be completed in half a day.” Jiang Anping said with a smile.
By the end of 2022, Wusheng County has planted more than 50,000 acres of mulberry trees, and about 4,000 villagers in 76 villages are engaged in mulberry tree planting.
Electrification of greenhouse breeding can raise six seasons of silkworms a year
Yang Junwei plans to breed seven seasons of silkworms this year. “With enough electricity and the use of electrified equipment, this goal can definitely be achieved.” Yang Junwei is full of confidence.
“The mulberry fruits are beaten into balls, and the silkworms are sleeping; the mulberry fruits have turned black, and the silkworms are in bunches.” Mulberry trees grow for three seasons, and silkworms are raised for two seasons. This is the rule summarized by people in Wusheng County after decades of raising silkworms. Now, this pattern has changed.
Before returning to his hometown to set up a factory, Yang Junwei communicated with agricultural technical consultants in the township many times and asked how to maximize profits. He has been thinking, in addition to reducing breeding costs, how can he raise silkworms for a few more seasons?
“Carry out greenhouse breeding, shorten the cycle, and increase production batches.” The words of the agricultural technical consultant made Yang Junwei excited and suspicious: A greenhouse is calculated as 4,000 cubic meters, using air conditioners and other equipment with matching power, excluding electricity costs. How much money is left? He quickly consulted Teng Changqing, director of Leshan Power Supply Station.
Teng Changqing modeled and analyzed the energy consumption of the greenhouse according to the parameters of the electrical equipment and space size in the greenhouse, simulated the electricity consumption of the smart greenhouse after it was put into operation, and proposed an electrified sericulture plan. He preliminarily calculated that the annual electricity bill of the greenhouse should be 110,000 to 130,000 yuan, which can save 200,000 yuan compared with artificial breeding. Yang Junwei decided to try electrified farming.
“To build a breeding greenhouse and improve the infrastructure, the most urgent thing is to install two 630 kVA special transformers.” Yang Junwei said. Teng Changqing assisted him in submitting an application for telegraph equipment. Leshan Power Supply Station arranged for the Taiwan district manager to follow the entire process and assigned technicians to guide him in installing electrical equipment. Before the construction of the greenhouse is completed, the power supply equipment is put into operation in advance.
At the beginning of the year, Yang Junwei successively introduced new smart silkworm breeding equipment that integrates mulberry uniformity, disinfection, mulberry feeding, net laying, and sand removal to create an all-electric breeding base. With more equipment, the requirements for electricity are naturally higher. The Taiwan District Manager of Leshan Power Supply Station monitors the powerquality of the silkworm breeding base in real time, and often goes to the base to check the power consumption of the equipment during key periods such as the breeding period of male moths.
“Electrified sericulture, the quality of silkworm seeds is high, and silkworm babies can be produced ten days earlier than before. The sericulture cycle has also been shortened. I raised 6 seasons of silkworms last year.” Yang Junwei introduced.
In 2022, there are 10 large sericulture households in Mengshan Township with annual profits of more than 170,000 yuan. Net profit of Yang Junwei’s sericulture baseto 250,000 yuan.
Provide customized services to reduce enterprise energy costs
On January 31, in the silk reeling workshop of Sichuan Antai CocoonSilk Group Co., Ltd. in Zhongtan Industrial Park, Wusheng County, rows of neat production equipment were at high speed It operates to process the snow-white cocoons into silk threads. “The raw materials to be reeled today are already piled up and we are very busy.” said silk reeling worker Tang Jianchao.
Sichuan Antai Cocoon Silk Group Co., Ltd. is an enterprise integrating sericulture production, cocoon harvesting and drying, silk reeling, silk weaving and home textiles. It mainly processes and sells silk and silk products.
“Now, with the use of electrified processing production lines, if there is any problem with the power of the equipment, the ‘electricity housekeeper’ will come to help us deal with it immediately.” Chen Lin, the company’s marketing director, said that every month, the “electricity housekeeper” will come to inspect, Maintain power distribution lines and electrical equipment, and establish safe power usage files, technical data ledgers and management ledgers.
At the end of 2021, Wusheng County Power Supply Company established a customer account for the electricity demand of the textile industry, provided customized services under “one enterprise, one policy”, and organized a dedicated “power housekeeper” to analyze the load situation for corporate customers on a regular basis , conduct electricity energy efficiency analysis to help customers reduce energy costs.
In March 2022, the “Electronic Butler” discovered that the power factor of the special transformer of Sichuan Antai Cocoon Silk Group Co., Ltd. was as low as 0.92 and the reactive power loss was large, so he contacted the relevant person in charge of the company and proposed to use synchronous motors instead of asynchronous motors. Technical solutions such as installing reactive power compensation devices. After negotiation, Wusheng County Power Supply Company helped the enterprise install a reactive power compensation device, raising the power factor of the enterprise’s transformer to 0.95, saving energy costs for the enterprise.
As of the end of 2022, there are 10 silk processing companies in Wusheng County, employing more than 20,000 people. In 2022, Wusheng County produced 500 tons of raw silk, 1.5 million meters of silk, and 9,600 threads of reeling silk, with sales revenue of 450 million yuan and exports Earned US$10 million in foreign exchange.
