In early summer, in Yuzhong County, Lanzhou City, in a "Lanzhou Lily Detoxification and Improvement Tissue Culture Fast Multiplication Center", cans of lily seedlings were neatly arranged, and the staff carefully used scalpels and tweezers to cultivate the lily bulbs with bud-induced mechanism growth one by one through scale technology, and then nursery cultivation when the lily bulbs gradually grew green leaves in the medium utensils.

"In the past, lily cultivation was to break off the scales of small lilies around the big lilies as seed bulbs, which were of poor quality and low yield, resulting in poor lily reproductive quality from generation to generation." Lou Jiang, head of the agricultural and sideline products purchase and sales company in Yuzhong County, Lanzhou City, said in a recent interview that the company through this technology research and development, the best quality lily will be the mother for fast multiplication, and do a good job in breeding and seedling cultivation under the conditions of light and temperature, which can greatly enhance the disease resistance of lily seedlings and lay a technical foundation for the detoxification and genetic transformation research of edible lilies.
Lou Jiang, who has passed the age of sixties, has come to Yuzhong from his hometown Qinghai for nearly 30 years, starting from selling chemical fertilizers and operating agricultural materials, Loujiang has been dealing with land and farmers for half his life. With the increasingly fierce market competition and the acceleration of urbanization, Loujiang clearly feels that farmers are undergoing earth-shaking changes in farming, from methods and methods to the selection of seeds and agricultural materials, and their needs are increasing and gradually diversifying.
With the increase in the number of young people going out to work, the demand for agricultural socialization services is increasing year by year. Loujiang focuses on extending the company's "agricultural materials sales + agricultural socialization services" industrial chain, "bundling" agricultural materials sales and agricultural socialization services, through the promotion of demonstration soil testing formula fertilization, water and fertilizer integration and other agricultural technologies, the annual promotion of ecological liquid fertilizer 80 tons, land trusteeship 4,500 acres, and other services totaling more than 20,000 acres, breaking through the limitations of farmers' understanding of traditional agricultural technology and agricultural materials.

In order to improve the pertinence of crop fertilization, the company carries out soil fertilizer monitoring, through monitoring the soil samples provided by farmers, accurately grasping the content of nitrogen, phosphorus, potassium, pH and other contents in the soil, and making reasonable proportions of missing or substandard elements, scientific fertilization, and targeted to help crops grow better. At the same time, the construction of Yuzhong County Intelligent Fertilizer Center and Rural Liquid Fertilizer Fertilizer Station will be used to increase the supply of green and efficient agricultural materials such as organic fertilizer, biological fertilizer, water-soluble fertilizer, formula fertilizer, low-toxicity pesticides, and biological pesticides.
On this basis, Loujiang set up a UAV plant protection flight defense service team to carry out flight defense operations by training the company's business personnel. "This is the refined service provided by technological progress, which is what farmers really need." Lou Jiang said that compared with manual spraying of pesticides, UAV flight defense operations have obvious advantages and broad market prospects, and the "big data + Internet of Things" technology can effectively solve the specific needs of farmers.
In the process of providing agricultural socialization services, Lou Jiang noticed that Lanzhou, as one of the main producing areas of edible lilies in the country, has been decreasing the yield of lilies year by year due to the quality of seed bulbs, and many years of agricultural work have provided the company with relevant experience in bulb cultivation, coupled with the policy support of Yuzhong County and the support of scientific and technological research and development forces of surrounding universities and other scientific research institutes, in 2023, Loujiang will establish Yuzhong County Yudeng Ecological Agriculture Science and Technology Development Co., Ltd. to build a fast breeding center for tissue culture of detoxified varieties of Lanzhou lily.
Liu Mingliang, head of the Science and Education Information Unit of Yuzhong County Agriculture and Rural Bureau, said that Yuzhong County, as a large agricultural county, has accelerated the revitalization of the seed industry in recent years, carried out the integration of major varieties of research and development, promotion and application, and comprehensively launched the implementation of the Cold and Drought Modern Seed Industry Innovation Valley of the Silk Road in Lanzhou, China, and strengthened the research on the provenance of lilies and Chinese herbal medicines, and strived to solve the problems of lack of improved seeds, low gene richness and poor antiviral ability in the field.

Taking lily as an example, lily bulb breeding bases have been built in Chengguan, Heping, Xiaguanying and other townships in Yuzhong County, producing 30 million detoxified bulbs. A lily germplasm resource bank and a detoxification tissue culture center were built. By the end of 2025, the county's intensive vegetable seedling breeding capacity will reach 500 million, the annual production capacity of lily detoxification bulbs will reach 50 million, the production capacity of potato original seeds will reach more than 60 million, and the breeding area of Chinese herbal medicine seedlings will reach 2,000 mu. The rate of improved varieties of major crops has remained stable at more than 98%.
"Everything is difficult at the beginning, and we now have to cultivate lily bulb seedlings like taking care of babies, and do a good job of collecting basic information." Lou Jiang said that starting from the strict control of the relevant operating regulations of the laboratory, the research on the cultivation of bulbs must go through a boring and long process, without the support of a large amount of basic data, this work is a "pat on the head" decision, and can not really solve the problem for farmers.
