On february 3rd, the chinese youth network xian (journalist zecharie) in the lanzhou river, the mountains are covered with frost, and 55,000 acres of lily fields have faded to the summer green waves, and dark brown fields have surfaced. This is china's only sweet lily-cultivated area, with a cold climate high above sea level, unique soil conditions, giving birth to lanzhou lily, which is of high economic and nutritional value, and enjoying the reputation of the chinese lilies。
“after the harvest in april of the previous year, we had planted green manure in the field, which was turned over and combined with the application of microbacterizers. The soil was soft and lily had a better future.” song xiaoxia, senior agronomist, agricultural radio and television school, 7th river region, lanzhou. This technique, known as “green breeding union”, is the product of years of experience of their teams — nothing more than to improve soil health, to change villagers' traditional planting concepts and to restore the land, which has raised countless farmers。
However, “restoring” land is only the first step. In song xiaoxia's view, land improvement ultimately serves the growth of lilies, whose quality and productivity are dependent on the dual guarantee of scientific breeding and precision management. As a result, she and members of the team ran to the lab and the field to measure the land by foot and step, to solve the problem with technology and to place a set of “good breeds” firmly in the lilies。
The ivory tower and the lilies' collision
As a native-born rural child, song xiaoxia has a natural affection for the land. In 2012, she graduated from a master's degree in crop genetics at gansu agricultural university and came to work at the agricultural rural directorate of the seven river region as an agricultural extension worker. It seemed like a professional counterpart, but the job gave her considerable frustration at the beginning。
She was young and her understanding of agriculture remained in a bottled tank at the university laboratory. The theoretical knowledge, which has been tested on numerous occasions, appears to be solid, but separates itself from the real scene of the field. For the first time in the countryside, she was nervous and sweating in the face of a group of farmers of the same age as her father。
“it was not clear at the time that lily was giving birth, and the people asked me when it was most effective, and i couldn't even answer.” song xiaoxia frankly said that for the first two years, she had been lost or even regretted by a huge gap in reality, “the knowledge she had learned was useless”. On the other hand, she even remembered the days when she was a biology teacher in the west, “the teachings were produced quickly and the agricultural effects were too slow”。
A turn-off from the field's head, "choose the wall" and "together." she followed her master in the village to deal with a complaint about a “false seed” which, by relying solely on the anomalies of the ground, determined that the farmer had mistreated herbicide before planting it, not the seed problem. This has made song xiaoxia aware that the knowledge of basic agricultural skills is far from sufficient. It has become even more necessary to integrate theory into practice for many years, so as to sharpen the “gold eye of fire” in both its symptoms。
From the time she identified the disease, to the time she learned to communicate with the farmer, she began to reawaken to the land and lilies at her feet, as she knew new friends. "just like taking a child, you have to know what it needs at every stage of its growth, when it's supposed to add clothes, when it's supposed to add food." song xiaoxia said. The care and patience of the crop has also led to the gradual loss of the beginning of her career。
The steady increase in professional capacity has given song xiaoxia the courage to challenge herself. For the first time in 2022, song xiaoxia, in her capacity as project manager, successfully applied for and chaired a municipal technology project on the collection and evaluation of quality resources in lanzhou. Song xiaoxia recalled, “but this project was requested by myself, and the stress and responsibility fell on my shoulders.”
Since the project's implementation, song xiaoxia and the team have collected a collection of lilies throughout the country, ranging from standardized planting to genetic identification in pilot fields, to comparative identification, which has resulted in the successful screening of several highly resistant and commodity-friendly good seed resources, which have enriched the local library of limo genetic materials and provided critical seed support for the improvement and renewal of varieties。

The project was small, but for song xiaoxia, it was a huge mutation, and her growth was not only reflected in the progression of professional competence, but also in the fact that she had finally made the laboratory's “bottle cans” fully accessible to the “soil smell” in the field。
"revitalization" for lilyda
At the end of the winter, the fields in the seven-mile river area of lanzhou, gansu province, were silenced. The grower, li dongping (alias), walks in the fields and knows the year ahead. He will take advantage of this time to “better” the field and make the next lilies more full and sweeter。
In the past, li dongping has been following past experience: once the harvest was over, the land was given a break of six months and then the next one was planted. Until song xiaoxia and the team brought about a new approach, he realized that “farming land” was one of the key elements of limo production。
“the lanzhou lily is the product of the national geography and the best species of lily for our food. The people of the seven mile river, who have lived on it for generations, say song xiaoxia. It is because of the years of growing that the problem of re-emergence has become more acute: soil sheeting, reduced fertility, increased pests and pests, and the quality of lilies. “it is not just a technical matter, but a direct concern for the livelihood of a family.”
In 2022, inspired by traditional agricultural wisdom, song xiaoxia and the team developed a comprehensive programme covering rotational fallback, biobacterism control: during the period following the lily harvest, green fertilized crops, such as larvae, mashed leaves and wheat, are grown on a wheel, which are then pressured back to the field and then used with specific microbacterial agents to improve the soil. However, this relatively slow “place-keeping” approach is not easy for farmers who are used to quick-impact fertilizer。
"it's the green wheel, as my ancestors have done." song xiaoxia said, "how can the crops grow better when, after the spread of fertilizer, many people have changed their minds and are trying to solve the problem with fertilizer pesticides `short and smooth'? "
Li was dealing with the agricultural and rural directorate in the usual years, and he hesitated when song xiaoxia offered to borrow his lilies for the experiment. "what if we fail and delay the harvest?" however, out of his confidence in the professional competence of the team, he eventually drew a three-point line and gave it to her. Song xiaoxia is more nervous than anyone: “we provide seeds and bacterial agents, and what i fear most is that they affect farmers' incomes. Tests can fail after all."
In that year, li dongping's lily field grew a small piece of arrow beans, fur leaves and wheat. The effects are visible after a few months. The soil of the test fields was significantly more loose, and the lily sprouts planted in the same year were thick and oily. Final accounting, with an increase of over 15 per cent. “the real gains are the most convincing,” song xiaoxia said. Lee dongping has also changed from hesitation to a technical campaigner. Today, the technology has been widely disseminated in the non-high-altitude lily area of the seven river region, becoming a “dwelling treasure” recognized by farmers。

In addition to this, and in response to the low and seasonal rainfall of the seven mile river, song xiaoxia and the team have integrated optimization based on traditional straw cover techniques to form an integrated cultivation model of “straw cover + microbicides” suitable for dry zones. The hydrocoercion of the critical period of lily growth is effectively mitigated by microbial activation of the slurry decomposition, which increases the temperature and supplements the organic matter while protecting the luminum. "there is more than 200 pounds per acre than before." song xiaoxia says. That sense of achievement cannot be expressed in words when it comes to the real benefit of farmers。
“shoes and sweatshirts will always be in the office, and we will be ready to go home.” this is the first lesson that song xiaoxia learned from her master and has become her habit to this day. Only by leaning down and listening to the needs of the land can the harvest be more full and sweeter in the long season。
Put technology into the people's minds
“agricultural technology diffusion is sometimes more important than technological innovation.” song xiaoxia said that grass-roots agricultural extension was a bridge between laboratories and fields and that many problems were hidden in the usual operations of farmers. For more than a decade, song xiaoxia has become more aware that agricultural extension is like a breeding ground and cannot be stopped。
In one of the trainings in huangzhou, the farmers reflected their own lilies. At the end of the training, song xiaoxia followed the farmer to the field and looked at “two plots adjacent to each other, one green and one yellow. “inquiries about planting, fertilization and the whole care process, eventually locking the symptoms on farm fat。
“the farmer knows that the farmer is well fat, but neglects the key to fattening, which is counterproductive if not time.” this has shown song xiaoxia the importance of agricultural extension, “the common sense we believe is often the most easily ignored blind spot for farmers”
She therefore greatly values every training. In the classroom, she talks to farmers about the widespread but easily neglected problems found at the grass-roots level. When technology is broken and made clear, farmers will soon be able to accept and change。

According to rough statistics, song xiaoxia is in the countryside hundreds of times a year. She's been in the field for four days a week. From the first college student in his high heels, who now travels through the lab with the lilies and is very well recognized by the farmers, song xiaoxia, 13 years of youth, has interpreted the meaning of the new age of “new farmers”。
Song xiaoxia, who is the beneficiary of the “light of the sun” talent development programme and the “young talent of the sunwon youth” project, has felt the need for policy support for grass-roots technicians on the path to research. These opportunities allow her to move out of the “small circle” and to reach out to more cutting-edge thinking and approaches. Today, as project leader, she began to think about how to attract more young people into agriculture。
“agriculture now is not just facing the yellow earth, it requires new thinking, new methods.” song xiaoxia says. In the future, she wants to lead more young people in this promising land in the west, using the scientific “good law” to keep the roots of the lily field to its own “richness”。
