Yuan Longping’s super hybrid rice transplantation hits the world record. What kind of glory is this?

Gu Yuzhe completed the transplanting of the grass hybrid rice "Caoyu Tianhu" in Longping, Caoba Town, Honghai Prefecture City, Yunnan Province, and the transplanting work was carried out as scheduled. In this transplanting plan, all 2,000 trays of seedlings born on March 20 will be moved to 101 acres of rice fields for planting. The radish yield is expected to be 1,200 kilograms, which will hit the world record for rice yield. Guyu Zhe, water makes all things moist. At the Yuen Long Pingcao Zaqiao Rice Experimental Exhibition in Qianjin Village, Caoba Town, 115 local villagers were busy transplanting the Caozaqiao rice. They skillfully and tacitly transferred the rice seedlings from the greenhouse to the test site for precise spacing and transplantation. , transplanting rice and a series of tasks.

Monza Super Hybrid Rice has started technical cooperation with the Plateau Breeding Center of the National Super Hybrid Rice Technology Center in 2017, hiring Yuan Longping’s expert team for comprehensive guidance, and conducting key research tests mainly with "Super Excellent Tianhu". The Longpingcao hybrid rice demonstration area in Qianjin Village, Caoba Town has flat terrain, flat fields, convenient irrigation, and an annual average temperature of 18.8, making it suitable for planting a variety of crops. The seedlings transplanted this time were transplanted in early mechanized greenhouses. Based on high-quality germplasm resources, the whole process of rice growth was tracked and accurately diagnosed. The most necessary and least number of times of work were used to use the most appropriate technology at the most appropriate time. Rice is quantitatively managed. “High yield, disease resistance, cold resistance, and tolerance are the common advantages of third-generation hybrid rice compared with the previous two generations. This production is also an important reason why the rice yield per mu exceeded 1,500 kilograms in the two seasons under extreme adverse weather conditions. " said Li Xinji, researcher at Hunan Hybrid Rice Research Center and director of the third-generation hybrid rice project.

Helping to solve the problem of climate risk constraints for high-yield hybrid rice seed production is an important part of Hunan meteorological services. Since the 1990s, the Hunan Meteorological Department has fully implemented personalized services for hybrid seed production, making positive contributions to achieving the goal of ultra-high yield. “Meteorological support plays a key and irreplaceable role in the seed production and promotion of hybrid and super rice.” Yuan Longping, the “father of hybrid rice,” fully affirmed the meteorological service for hybrid rice seed production. "For rice to have high yields, it must have four qualities. First, good varieties; good planting methods; better foundation; and a good climate." Yuan Longping described the relationship between climate and rice yield. To achieve high yield, hybrid rice cannot be separated from high-quality rice seeds. In other words, seed production can be said to be the “mother project” of hybrid rice production.

Two-line hybrid rice has strong vitality, but in the early stages of development, the progress was not as smooth as everyone expected. Because hybrid rice is easily affected by climate factors such as temperature and light during hybrid seed production, it faces serious climate risks. In the early stages of the development of chicken farming, the laws of climate impact were incorrect, and hybrid rice repeatedly experienced "impure" and "false" breeding and seed production, resulting in seed production failures and heavy losses. This raised concerns about the prospects of hybrid rice using chicken farming. widespread concerns.
