At noon on January 17, as an experienced sericulture farmer, Luo Jiaoling, a villager in Hongdu Town, Xincheng County, Laibin City, Guangxi, was not busy picking mulberry leaves to feed silkworms like other silkworm farmers. Wash vegetables and rice in a leisurely manner. This was completely unimaginable before.
“After switching to feed to raise silkworms, I have a lot of free time. In previous years, I was so tired from picking mulberry leaves that my back ached.” As she spoke, Luo Jiaoling took the reporter to her small silkworm breeding base. Under the constant temperature equipment, the wind is biting outside and the room is as warm as spring. Nearly 30,000 silkworms are neatly grown and strong, and are wolfing down the feed. These feeds, which are made of mulberry leaves, corn flour and other raw materials, are mixed with water, stirred and steamed, and turn into soft green lumps, faintly exuding the fragrance of mulberry leaves.
With good climatic conditions, Xincheng has a tradition of growing mulberry and raising silkworms. Luo Jiaoling told reporters that she watched her family raise silkworms since she was a child, and inherited the family business when she grew up. The current base was built in the second half of 2020. It has a total of 5 small silkworm co-breeding rooms. It mainly carries out small silkworm breeding, comprehensive utilization of sericulture resources, demonstration and promotion, etc., and more than 12,000 small silkworms are reared annually.
The sericulture industry is a traditional labor-intensive industry. With the development of green and efficient agriculture with high quality, the sericulture industry Innovation is also needed to achieve upgrading and transformation that is scale-saving, labor-saving, efficient and modern. At the beginning of 2021, the base cooperated with the Laibin Academy of Agricultural Sciences to build a new silkworm artificial feed breeding room, and established a silkworm artificial feed breeding demonstration site. By introducing automated heating and humidifying equipment, silkworm artificial wet body feed cutting and feeding machines and other equipment to “arm” the silkworm room, the convenience and efficiency of the silkworm room were improved. During the year, 4 new varieties of feed-bred silkworms were introduced, and 5 batches of moderately large-scale silkworms were successfully carried out. In the artificial feed breeding work, the total number of silkworms raised exceeds 1,000, and the maximum number of silkworms raised in a single batch reaches 404. The small silkworms raised are deeply loved by silkworm farmers. In mid-December 2021, the base used Haoyue Jingsong to promote a full-age feed breeding demonstration. The feeding amount was 4. It has now entered the sixth day of 5-year-old.
“If you feed traditional mulberry leaves like in the past, you need to feed them at least three times a day, and feed them once every two to three days for feed breeding.” Luo Ping, deputy director of the Laibin Academy of Agricultural Sciences and director of the Laibin Comprehensive Experiment Station of the National Sericulture Industry Technology System Introduction: The promotion and application of the artificial feed sericulture model is expected to change the labor-intensive traditional production model of mulberry planting and sericulture for thousands of years, and promote thetransformation and upgrading of the traditional sericulture industry. In addition to greatly saving labor and time costs, artificial feed sericulture also solves the problem of uneven silk quality due to the difficulty in controlling the quality of mulberry leaves. Driven by the standardization of the artificial feed sericulture model, it is not affected by seasons, climate, natural disasters, etc., and prevents and controls diseases, insect pests and pesticide poisoning, and the success rate of sericulture has increased by 5% to 10%. According to estimates, to achieve full-age artificial feed breeding, one labor force can raise 150 to 200 silkworm seeds every year, with a net income of about 600 yuan per seed, and an annual net income of 90,000 to 120,000 yuan.
It is understood that in the “14th Five-Year Plan” of the national sericulture industry technology system, silkworm artificial feed breeding is a key promotion task. Today, the Laibin Academy of Agricultural Sciences coordinates the comprehensive experimental and scientific and technological project resources of the national sericulture industry technology system and promotes the establishment of 6 demonstration sites for silkworm artificial feed breeding, including 3 in Xincheng, 1 in Xiangzhou, and 2 in Xingbin. Artificial feed sericulture will become a new labor-saving model of sericulture in Laibin City with “small silkworm feed breeding and large silkworm strip mulberry breeding”.
