I'm a reporter
In the ministry of agriculture and rural development's declaration on the validation of major crop varieties for 2025, 153 new wheat varieties were passed through the state review, and shaanxi accounted for 18 of them. Of these, 16 are of yang ling origin, with a national rate of 10. 46 per cent and an annual average of both the number and percentage。
Up to now, wheat varieties with the yang ling gene have accumulated over 2 billion acres, resulting in an increase of over 50 billion kg。
This year, a breakthrough of 434. 4 kg of acre production was also achieved for the new wheat species “mixer 19”。
Behind these achievements are the solid underpinnings of agricultural science, technology and innovation and the years of hard work by agricultural experts on the ground。
As a “national team” for the development of modern agriculture, why does yang ling continue to produce gold seeds? The answers are hidden in the footprints of a generation of generations of breeders who struggle to survive, in terms of laboratory-to-field scientific and technological promotion, and in an open pattern to the national, connecting world。
"breeding is hard to bear."
On 28 september, in the wheat hanger room of the northwestern university of agrotechnologies, professor jiewan and members of the team were busy placing the sifting of good wheat seed numbers, sequencing and planting for the autumn。
The northwestern university of agroforestry, located in yang ling, china, has over 70 wheat breeders. Givan is one of them。
In 2018, the “sinon 511” wheat species, developed by the giwan group, achieved technology transfer at a cost of $4. 55 million, resulting in a record transfer fee for the shaanxi wheat varieties. This variety has accumulated nearly 40 million acres in the henan, anhui, jiangsu, etc., at a purchase price of 4 cents per kilogram higher than the normal varieties。
The breakthrough originated from an unbroken crop of wheat seed "relay."。
"breeding is the choice of a good seedling." this process has to last solitude." gilwan says everything。
The insufficiency of young people has given gilwan a special emotion to agriculture. In 1979, he was admitted to the north-west college of agriculture (now north-west university of agroforestry and technology) and in 1985 the teacher embarked on the path of wheat breeding from the wheat genetic breeder lee jinh。
To this day, jiwan remembers clearly the first time 40 years ago that he followed lee jin-soon in a ditch。
"i'm doing it fast with my youth. Mr. Lee said, "you're not opening up straight, you're in the middle. Cultivation must be hard-hearted and not easy. "mr. Lee's busy schedule is free to open ditches, harvests and pull cars with students."
Strictness is an important quality that jiwan has learned from his teachers。
Today, whenever a new student is enrolled, the giwan clan has placed the first class in the field。
“agriculture cannot be feared. Only in the field can you find the problem." over the years, a group of students, along with giwan, stepped on the mud fields to find their way to the wheat and slowly understood the meaning of the word “transmitting”。
The birth of a new varieties of wheat is often the result of combinations, intergenerational choices, multi-wheel trials that eventually emerge from thousands of strains. In shaanxi, a generation of breeders write thesis on the earth -
In the 1950s, the team of hongjian students planted the "beiwei 1" to raise the country's wheat acre production from 80 to 200 kg in a rust-resistant and productive manner
In the mid-1980s, the team of li jin-soon was formed as the “sittle six”, with more than 80 derivatives, which became the primary home of the country's wheat breed
In the mid-1990s, the lilik team pioneered the technology of “silver-free-stretching” to save irrigation water and break agricultural production bottlenecks in drylands
I'm sorry
From generation to generation。
Since its inception, more than 1,000 wheat breeders have taken root, forming the “most powerful brain” in china's dry-zone agriculture, and have grown more than 200 new varieties of wheat, such as “sun farmers” (7859) and “sinnon 979” (sinnon 511). These new varieties of wheat from yang ling have led many times to the renewal of varieties in our yellow wheat district。
"each seed is a matter of national food security." that's all。
It's a legacy of faith from generation to generation, and it's the beginning of a wheat field. Generations of shaanxi breeders have laid a solid foundation for the country's food security, so that every seed becomes the bottom of a steady chinese job。
"and can't give up"
Fires that breed relays continue to spread to wider fields。
Zhang li, a leading expert in wheat at the university of agricultural sciences in suan city, is one of the “benchers” of this relay。
“accounted 8. 62 acres with an average acre production of 434. 4 kg.” on 26 september, reminiscent of the scene of the live harvest this summer, zhang zianli's excitement remained elusive. At the same time, the breeder, who had been growing wheat for 30 years, was relieved when he was standing on a field where wheat was being used to demonstrate efficiency at the suntown test station “mine 19” and watched the harvester vent pouring grain。
In 1995, zhang zhang li, a graduate of the university of north-west agriculture (the predecessor of the north-west university of agroforestry and technology), was placed in the pilot station of the uynan city institute of agricultural science in the village of ganbei, sun town。
“in the early stages of the national experiment with wheat in the light drylands, most of which was promoted by the introduction of other wheat varieties, which could be tested but not developed on their own, it was felt that it was not the feeling to hold someone else's `child'.” zhang li stated that this “unsatisfiedness” allowed him to set a target — it was important to develop a quality dryland wheat variety and embrace his “child”。
The test of reality follows. In 2000, the difficulties peaked — the test field was drastically reduced from 50 to 12 acres, leaving only over 200 precious seed resources in dry weather。
With this tenacity, the zhang li team has tried repeatedly to produce more than 400 hybrids。
In 2011, zhang zhang li finally received his “child” — a wheat with both drought-resistant and productive properties finally emerged and was named “mega 9”。
The breeding road has no end. In 2016, zhang sali launched the mew 19 offensive. This new species requires much more technology than ever before, both to preserve the core of drought-resistant and cold-resistant genes, and to embed the “straw-resistant and disease-resistant” bones. To this end, zhang zhang zi li invited professor wang bautung and others to the north-west university of agro-forest technology。
"we're conducting an anti-generative and anti-pathological screening of wheat for the whole province's breeding unit, helping to pre-screen the highly resistant "good seedlings." wang paul says。
It's normal for wang paulton and many of his colleagues to work in the field for more than 20 days a month. In shaanxi, a group of agricultural experts traveled year after year on “hope fields”, with “hand hands” delivering technology and services to farmers。
With the combined efforts of zhang li and the “midwives”, the performance of mew 19 fell short of expectations。
Through the integrated application of the "water preservation + precision seeding + three blast-proof" technology system, the seed capacity of mew 19 without a drop of water exceeded the water-fed area, with a steady yield stabilization of 434. 4 kg. Behind this, the expert “takes the wheat side”。
In recent years, yang ling has carried out intensive crop-rehabilitation activities, set up innovative platforms in the arid zone agricultural xinxi laboratory and the yang ling industry innovation centre, established a bioculture technology innovation system, represented by wheat, maize, potatoes and vegetables, and created a technical innovation team, headed by 12 faculty members, and “silica valley for dry zone crops” to build steady foot and foot。
At the moment, shaanxi is accelerating the construction of a 360,000-acre wheat breeding base, with a planned annual production of more than 140 million kilograms of good seeds, which will enable the population to keep their jobs firmer and more full。
"let the good breed produce a strong, productive `gold ears' in the drylands."
In jiangsu xuzhou, wang xiao, the head of the rich agricultural business department in pei county, is very busy. He communicates almost daily with his colleagues who come to “take lessons” and shares the fruits of cultivation。
"it's been five years since i planted sinon 511. It's a very high-quality, strong breed, and i'm very good at it." wang xiao not only recognized the species from shaanxi, but also led the surrounding growers to plant it together, “everyone loves it. Next season, we're going to have to scale up the seeds."
The “sinon 511” circle is a microcosm of the country's exposure to agricultural technology. It also needs to be backed up by good technology to root the good species in the drylands。
Wang dong, vice-president of the faculty of agriculture of the north-west university of agro-forest sciences and a member of the steering group of experts on water conservation agriculture of the ministry of agriculture and rural affairs, has a long-standing commitment to research on the theory and technology of high-quality and green wheat cultivation. He shares the same goal with jiwan, zhang li, “letting the good breed produce a strong and productive ‘goldho’ in the drylands.”
“the regulation of water fertilization is a key factor in increasing the production of single crops.” wang dong said that previous cultivation techniques, the application of fertilizers and irrigation were often separated from water, and the effects of fertilization were not fully developed; overfilled at a time, which in turn led to the loss of fertilizers to deep soils and waste。
The integrated monolithic upgrading of wheat fertilizers developed by the wangdong team, which integrates the two, has effectively addressed the technical challenges of water scarcity, water fertilization efficiency and low-yielding industries in dry areas。
One of the practical points of this technology is the town of hyungjiang in dalang, taian, shandong province。
“the water used for irrigation once per acre was about 100 cubic metres and now only 25 to 30 cubic metres.” the technology of professor wang's `hand hands' teaching not only saves water, but also reduces labour intensity. This year's output is much higher than in the surrounding villages."
Last year, the wang dong team developed the “integrated single-production upgrading techniques for wheat water fertilizers” and the “deeply lax storage tectonic fertilisation techniques”, both of which were selected for the national agricultural technology extension service, “ten bright spots in the fertilizer sector”。
The radioactivity of yang ling agricultural technology has already crossed geographical boundaries。
Since 2019, yang ling has been implementing almost 130 training programmes, and distance technology lectures have attracted 48,000 online learning sessions。
Moreover, yang ling has built 10 overseas agricultural science and technology demonstration parks in sco countries, sending a total of 73 batches of more than 190 specialists into exotic fields, completing the testing and promotion of 115 good varieties of 13 major varieties, such as wheat and maize, with a radiation-driven area exceeding 30 million acres。
As chinese agricultural wisdom benefits more countries, yang ling attracts more and more agricultural talent from abroad to study. The chinese programme and the spirit of friendship have helped to transform local agriculture and promote more worldwide agricultural issues。
A seed can change the world. From the land of the san qin, the grains of “swidth wheat” crossed the mountains and seas, growing and harvesting。
The “sun-hy-sweet-sweet-sweet-sweet-sweet-sweet-sweet-sweet-sweet-sweet-sweet-sweet” not only reflects the beginning of a generation of “good-for-life” breeders, but also engraved in china’s self-reliance in agricultural technology。
The shaanxi breeders have fallen to the ground and struggled to build strong strength for the harvest of “china's food” and have allowed china, which is rich in the drylands, to continue to write new legends on its journey to guarantee global food security。
