Jiao Hongye, born in November 1977, is a member of the Communist Party of China, a corn breeding expert of Handan Academy of Agricultural Sciences, Hebei Province, and the first prize winner of the provincial scientific and technological progress award. Over the past 24 years, in order to promote the construction of a strong agricultural province, he has presided over and undertaken more than 20 scientific research projects, bred 16 maize varieties, promoted more than 50 million mu of planting area, and created economic benefits of more than 2 billion yuan Provincial influential agricultural experts.
At 5:10 a.m. on April 12, Jiao Hongye hurried into the corn experimental field of Handan Academy of Agricultural Sciences in Nanbin Farm, Yazhou District, Sanya City, Hainan Province. Today, he was going to take the 6:55 flight from Sanya Phoenix International Airport back to Handan, but he still used the gap before going to the airport to come to the corn experimental field and take another look at the last phase The growth of corn.
In 1999, Jiao Hongye, who graduated from Huazhong Agricultural University and majored in plant genetics and breeding, came to Handan Academy of Agricultural Sciences to start corn breeding research. For more than 20 years, he has been working in the front line of corn breeding research, and spent many Spring Festival in the corn experimental field in Sanya Of.
From the beginning of August to the middle of August every year, although there are only 20 days, it is also the hottest season of the year. At the same time, it is also the season of artificial pollination for maize breeding. Jiao Hongye, an agricultural expert, wore heavy work clothes and carried paper bags, survey books, pens and labels Scalps and scissors pollinate corn.
"In my eyes, every corn is a living life." Jiao Hongye introduced Said that since it is a living plant, it has its unique characteristics. Jiao Hongye said that after long-term observation, he knew what characteristics each corn had and which corn was suitable for teaching Pollen and planting density.
"My teacher spends more than 20 days a month in the corn experimental field, and his clothes are no different from ordinary farmers." Fan Ziyang, a member of Jiao Hongye's innovation team, said, "No None of the surrounding villagers who are familiar with the situation contact him with agricultural experts.
Jiao Hongye introduced that he had been living in a rural area of Linzhang County before he went to college. He said that for many agricultural research workers, their love today is not their original ideal. The majority of people should be the volunteers who have been adjusted, or the volunteers who are very backward. But he loved what he did. After taking root in agriculture, he began to turn the breeding work that had previously been regarded as suffering into a kind of enjoyment. Two years before I went to work, I was always looking forward to getting off work in the field. When I was sweating, I felt that I could not hold on for a moment. But ten years later, although I was soaked through, I always felt that time passed quickly and time was not enough. Why? Because I had goals in mind and had too much work to do, the pollination work was only 20 days a year, so I was afraid of missing something. He said that in hard times, without love, every second is suffering, on the contrary, every second is exciting. It is this adherence to the craftsman's spirit of "dedication, excellence, meticulousness and excellence" that finally Corn breeding has become the favorite thing in my life.
Jiao Hongye has made remarkable innovations in germplasm creation. Serious homogenization and lack of germplasm resources are the biggest obstacles to further improve the yield level and stress resistance of maize. The germplasm base is narrow and the heterosis model is single. Seriously affected the improvement of maize varieties.
He created a new type of Core parents of H39 and L11 series maize. The innovative method mainly reflects three ideas. One is that the basic population is composed of many, and excellent inbred lines with complementary traits of different blood relatives are added. The inbred lines with many excellent traits were screened through field identification to form a population, so as to ensure that the population has rich and excellent genes; Second, through multiple mixing, to achieve the emergence of new genotypes with good genes together, to ensure the novelty of the created germplasm; The third is to isolate the male and only harvest the emasculated plants to avoid self pollination and obtain natural hybridization The effect of.
Jiao Hongye attaches great importance to the work efficiency of breeding. He has summarized a whole process efficient corn breeding program based on years of experience, which has greatly improved the efficiency of corn breeding and accelerated the breeding of excellent varieties. His idea of focusing on methods and variety research is very valuable in the industry. In each treatment stage of breeding, he carefully pondered, repeatedly experimented, and invested a lot of energy to explore the scientific and reasonable application of computer processing functions and other modern equipment in the breeding process. This kind of combination of computer data processing, modern breeding equipment and breeding practice re optimizes the design of relevant processing details, which makes the team's ability to handle breeding operations several times stronger, improves breeding efficiency, supports a larger breeding scale, and increases the probability of breeding excellent varieties. His team has learned from other breeding units in many technical difficulties Imitate, and obtain a number of software copyrights.
In 2021, the Hanyu 1604 maize variety bred by Jiao Hongye and his team passed the national approval. Because of its excellent performance, its application prospects will be even broader. In recent years, Jiao Hongye and his team have bred 10 maize hybrids, which have passed the examination and approval both inside and outside the province. Among them, Hanfeng 08 and Hanfeng 79 The promotion record of the self bred variety with the largest planting area in Hebei has been published, and the variety application areas are all over the river North, Henan, Shandong and other places, with a total promotion area of 50 million mu.
When feet step into the soil, the paper is written on the earth. All kinds of corn bred by Jiao Hongye are growing in North China. But Jiao Hongye did not stop. He said that he would continue to speed up the cultivation and promotion of fine varieties, and implement the "biggest player in the country" of food security Go to the field and contribute the greatest strength of an agricultural technology craftsman to secure China's job.
