Now, as an academician of China Academy of Engineering, Yuan Longping has devoted himself to the research of hybrid rice since 1960s. After 12 years of hard work, he has successfully cultivated? Three-line hybrid rice From 1976 to 1987, the planting area of hybrid rice he cultivated reached 1 1 100 million mu, and the rice yield increased by 1000 billion kg, and the yield increased by 1979. As the first agricultural technology patent in China, hybrid rice was transferred to the United States. Later, he developed a number of existing three-line hybrids.
1 1.2, the yield measurement results of late rice in Hengnan County, Hunan Province, the average yield per mu reached 9 1 1.7 kg. In July this year, the average yield per mu of early rice was 6 19.06 kg, which means that the average yield per mu of the third generation hybrid rice of double cropping rice in the morning and evening exceeded 1.500 kg (3,000 kg), reaching 1.530.76 kg. Team Yuan Longping's double-cropping rice yields more than 3,000 kilograms per mu.
How many people were shocked by this move? According to incomplete statistics, the national grain output will increase by 30 billion kilograms, which can support an additional population of 80 million to/kloc-0.0 billion. ? One hundred million people, how huge this number is. This one? Grades? It is about 30% higher than the high-yield area of ordinary double-cropping rice, and about 50% higher than the average yield per mu of double-cropping rice in Hunan. At the same time, the demonstration film saves fertilizer and cost, and has economic and ecological benefits. According to estimates, the yield per mu of early rice is 259.7 kg higher than that of a large area, and the yield per mu is 623.3 yuan. The average yield per mu of late rice is 290 kg higher than that of large area, and the yield per mu is 730.8 yuan. Counting the two seasons, the income per mu 15438+0 yuan. ?
These actions are very gratifying to people who don't have enough to eat and to well-off farmers. We also look forward to Yuan Lao's next successful move.
