He Yunchuan (left) and Zhou Ying are changing the armyworm board.Reporter Zhou Yajun took the year of the Tiger in Sanya, Hainan, with green trees and red flowers, and red lanterns hanging high beside the avenue.The National Breeding base of Nanfan is an important “base camp” for crop seed breeding in China.Every winter and spring, thousands of researchers come to make use of the abundant light and temperature resources to carry out crop breeding research, resulting in the professional term of Crop breeding in China: Nafan.It is estimated that 70 percent of the new varieties of crops in China have gone through southern propagation.The reporter came to the South Fan base, a look at the spring weather here.In Sanya Rice National Park, tourists pass through a small gate, bypassing the noise, and suddenly see a peaceful pastoral scene.Mu mu square pond, green rice, white herons, unknown birds dive, hovering, fishing, catching insects.The green mountains in the distance, together with the blue sky and white clouds, reflected in the paddy fields, outline the moving lines connecting peaks and valleys.Yang Hanshu, an assistant researcher at the Hybrid Rice Research Center of Hunan Province, has chosen to stay behind again this year, and this will be his fifth Spring Festival at the Base.Yang hanshu, who has been working at The Base since 2004, was shocked by the breakthrough in hybrid rice yields per acre.In that year, Academician Yuan Longping’s team cultivated “Chaoyouqian” hybrid rice in Nfan Base, which opened Yang’s eyes. “The ears are very large, with an average of 340 grains per spike, and 500 grains larger than normal rice, while only 270 to 280 grains.Lodging resistance is very good, no matter how long it grows, it will not fall, even when the rice is dry.”After that, the cultivation technology continued to break through, “super thousand” record constantly refresh, the per mu yield climbed all the way to more than 1100 kg, is still the main push of rice breeding.Yang Hanshu told reporters, division farm base 150 acres of land planted are blunt yield of new varieties, new combinations, protect 1000 kg, blunt 1200 kg, have not decided the name.”Farming time can not miss, farming time came, the first day of the New Year in the field as usual.”Yang hanshu’s main task is to take care of the healthy growth of rice. Every day, under the sun, he is busy in the paddy field wearing rubber shoes, lowering his head to observe the growth of rice materials and marking the leaf age and division.For rice, March and April are the busiest months in southern China, when a large number of hybridization tests need to be done, but the Spring Festival is also busy.Yang hanshu pointed to a block of sterile line material. “It was sown on November 10 last year, and now it is just coming out.”Take scissors in one hand, tweezers in the other hand, cut and shake powder, minute sweat can wet clothes.Having finished his work in the field, he was sitting in a pavilion in the courtyard chatting. Yang Hanshu pointed to the apartment building next to him. “Academician Yuan Longping used to live in that room.He fought and infected a lot of people.The best seed is always the next one, and we all share the same dream of producing a higher yield, better quality and more resistant variety.””Stick to the post, adhere to the original aspiration to do scientific research” In sanya Yazhou Bay Science and Technology City, the laboratory of Longping Biotechnology Company is still busy.”This Spring Festival, more than 90 percent of the staff stick to their posts and carry out scientific research.”Lv Yuping, general manager and chief scientist of the company, said that the year before last, due to the impact of the epidemic, many restaurants in the remote Yazhou closed their doors. After finishing work in the fields, it was too late to have a place to eat, so they roasted corn and sweet potatoes to appease their hunger.As a biological breeder, Lv yuping sees Nanfan as a heavy national responsibility and a life pursuit that gold will always shine.By virtue of the international advanced corn biological breeding technology and the full shareholding mechanism of the scientific research team, the company has grown to more than 60 people in just over two years, including many excellent talents from internationally renowned enterprises.”Longping 007 chip contains three insect resistance genes and one herbicide resistance gene, which has broad market prospects. The improved varieties can effectively resist nearly 10 pests and increase corn yield by more than 15 percent.”In the narrow office of about 10 square meters, Lv Yuping told the story after settling in the Science and Technology City, “In the past two years, I have to stay in Nafan Base for more than 300 days every year. Even if I go to Beijing for meetings, I always buy the earliest flight on the day and the latest flight back.””Scientists need to dare to step outside their comfort zone.”Lv yuping said, “Our goal is to guard the door of technology and become a real brand of science and technology city.”Recently, Longping Biology has taken a new step to encourage innovation, offering annual bonuses of 12 months, 9 months and 6 months to outstanding employees.Yi Jinqi, a 24-year-old girl from Hunan province, received a 12-month salary bonus.”Don’t underestimate this new student.In order to avoid the waste of scientific research materials, she practiced with the materials used by her colleagues after finishing her work every day. She could be seen busy in the laboratory almost every night.Only practiced for 4 months, professional ability has been comparable and the same industry has 2 years of work experience of the staff, corn embryo germination success rate is 5-10 times of others.”Lv yuping said.Yi enjoys working in the genetic transformation laboratory of corn, separating the corn germ smaller than a small rice grain under a microscope with his hands, and then going to the temperature and light culture room to cultivate the peeled germ into seedlings.”Technological route innovation, breeding cycle speed up, 90 days can grow a season of corn, there are experiments to do every day.”It’s amazing to watch the corn sprout and feel a sense of accomplishment when one’s interests and interests align with the needs of the country.””The more I understand the hard work of farming, the more I understand the value of scientific research.”Heard a sigh, the reporter looked at the sound, he Yunchuan is replacing a sticky insect board is full of worms.He Yunchuan is the first doctoral student of Zhejiang University, majoring in agricultural insect and pest control.Last year, their research group rented an acre and two halves of land in Daguan Village, Ya Town, Yazhou District, and planted two stubble of cowpeas to do basic research.”Cowpea is the main planting variety of winter melons and vegetables in Hainan, serious insect pests, the use of pesticides, the cultivation of insect-resistant cowpea varieties, is crucial to local development.”Zhejiang University Nanfan inspection and quarantine and crop health team leader Zhu Zengrong said.In the first crop, He planted 200 cowpea varieties and screened out 65 varieties with high resistance and susceptibility genes. In the second crop, he verified the screened 65 cowpea varieties.”Three to five cowpea varieties with insect resistance genes and insect susceptibility genes were screened out respectively according to the observation of continuous cultivation in the field and the means of laboratory biotechnology, to clarify the insect resistance mechanism and provide theoretical support for the green prevention and control of cowpea pests.”Cowpeas in the field come in all shapes, red, green, black and brown, and some of the slowest growing wild species have yet to flower.The cowpeas of the research group did not use pesticides, and the yellow and blue armyworm board with a size of 20 cm ×25 cm was replaced regularly. Then, through indoor counting, the species and number of insects were counted, and the population dynamics and diversity of insect pests were determined in each growth period of cowpeas.The resistance phenotypes of different cowpea varieties were observed in the field, and the related mechanisms were studied in the laboratory.During the Spring Festival holiday, the research data cannot be cut off, and the worms in the laboratory must be fed.He, together with zhou Ying, teacher of the research group, and Chen Qiulin, sealed the armyworm board with plastic wrap and marked the date of changing the board and the variety number clearly on the back. When harvesting seeds, the variety number was marked on the collection bag. Then he picked mature pods and prepared seeds for the next experiment.How do red pods differentiate between ripe and not?”If you pinch it, it has a crunchy sound and it’s done.”He yunchuan replied.A year in the south brings a lot of hardship.In order to avoid the sun, they got up at 5 am and went to work in the fields. Their clothes were soaked with sweat in the heat of more than 40 degrees Celsius. “It is not easy for farmers to increase their income.A lot of hardship, a lot of harvest.He Yunchuan in yazhou Bay seed laboratory application to host their first topic, “the New Year hope to have a new breakthrough”.People’s Daily (February 12, 2022 Edition 02)
