"Grape God of Wealth" Chang Yongyi drives Gansu Grape to the whole country

Chang Yongyi, professor of Gansu Agricultural University, vice president of Grape and Wine Branch of Chinese Horticultural Society, executive director of Grape Branch of Chinese Agricultural Association. He has successively completed 8 grape research and development projects at the provincial and ministerial level. Twelve new grape varieties suitable for cultivation in different regions of Northwest China were introduced and selected, with a cumulative extension area of 70, 000 mu and a cumulative income of nearly 1 billion yuan. The winner of the second moral Model in Gansu Province. For 30 years, he kept running between colleges and universities and the countryside, moved the laboratory to the field and wrote his papers on the earth. With his professional research and technical promotion, he has driven the great development of Gansu grape industry and made Gansu grape famous all over the country.

"Grape God of Wealth" planted "Cash Tree"

As early as 1976, Chang Yongyi threw himself into the vineyard. He and his colleagues successively introduced more than 100 new grape varieties at home and abroad for comparative experiments and adaptability studies, and selected 12 excellent new varieties suitable for planting under different conditions in Hexi. First of all, he did the promotion and application of varieties such as "Seedless White" and the technical guidance of new varieties in Dunhuang, making outstanding contributions to promoting the development of the local grape industry.

Since 2000, with the strong support of Dunhuang Municipal Government and presided over by Chang Yongyi, Dunhuang City has implemented the projects of "Construction of 10,000 mu Red Globe Grape industrialization Base" and "introduction and demonstration of New Grape varieties", which has further promoted the great development of the local grape industry. Among them, Qinjiawan Village, Qili Town, Dunhuang City, which only began to grow grapes in 2000, under the technical guidance of Chang Yongyi, planted 1140 mu of land in the village into a new high-quality American grape variety "Red Globe" that is resistant to storage and transportation.

The "rebound lute" of grape production

Chang Yongyi, who is determined to lead farmers to become rich with agricultural science and technology, is not satisfied with the achievements of Dunhuang City. He set his sights on the cold and arid mountain areas at high elevations with poorer natural conditions and the largest number of poor people.

Through "reverse thinking", Chang Yongyi developed and utilized the cool climate at high altitude as a "cold resource"; through more than a decade of research and technological innovation, he conquered a series of technical problems in the "forbidden area" of grape cultivation at high altitude. It has successively solved the techniques of high survival rate planting, stress cultivation, early fruit, high quality, high efficiency, water-saving and fertilizer-saving cultivation of grapes in alpine and cold areas, and the regulation and control techniques of delaying grape production to New Year's Day and Spring Festival harvesting in solar greenhouse. the technical standards for delaying grape seedling planting for one year, high yield for two years and full fruit period for three years in the northwest plateau were established. More than 50, 000 mu of grape planting facilities have been popularized in the northwest, with an annual output value of more than 1 billion yuan. The facility grape industry has lifted more than 10,000 farmers and herdsmen out of poverty at once.

Agricultural experts'"love for agriculture complex"

In Chang Yongyi's body, it embodies the excellent quality of agricultural science and technology experts to enrich the people, go to the grass-roots level, keep promises, and be willing to contribute. In the eyes of the common people, Professor Chang's technology is reliable and he can rely on grapes to get rich; in the eyes of grass-roots cadres and technicians, he is not only an important leader in the development of Gansu grape industry, but also his outstanding quality of enthusiastic service to "agriculture, rural areas and farmers" and honesty and pragmatism, which has set an example for the majority of scientific and technological workers.

From the late 1970s, he went from village to village to serve "agriculture, rural areas and farmers" in a donkey cart or walking tractor. Today, he has made remarkable achievements. He is willing to go to the grass-roots level, is not afraid of hardships, and perseveres. For decades, the green vineyard was his concern, and he had a heavy sense of responsibility and mission on his shoulders. In the process of dealing with farmers for a long time, an inexplicable "love for agriculture complex" has been deeply integrated into Chang Yongyi's life.
