Saying goodbye to hunger forever is a lifelong dream of mankind. ? The history of food is the history of human struggle against hunger. There is a folk crossword puzzle: water stays in the water for a long time when it is young, green when it is old, yellow when it is old, golden armor hangs down, pearls are hidden inside-rice, the upper eight is not like eight, and the lower eight is like eight, sitting in the middle of the cross to save the living Buddha-rice, which reflects the importance of food to mankind. When Yuan Longping went to Fenghuangpo Village to help farmers on 1960, he had the experience of starvation. Seeing others starve to death made Yuan Longping start to think and face the same hunger problem. In order to overcome this problem and make mankind bid farewell to hunger forever, Yuan Longping began to study rice at the age of 30 and began his lifelong pursuit. ?
Let mankind bid farewell to hunger forever? Yuan Longping was transferred from his teaching post to help farmers in Fenghuangpo village. Being hungry on the way, as a swimmer, he almost drowned in the river. He lives in Shui Sheng and is the captain of the production team. Shui Sheng's father, Uncle Hirota, is starving. He wants to eat a bowl of white rice and feel at ease. His son said: There is no rice at home. I really want to eat until this winter. Yuan Longping said to Uncle Hirota, I'll try to make you eat a mouthful of white rice. As a result, Yuan Longping didn't find rice. He suddenly realized that an intellectual who studied agriculture owed uncle Hirota a bowl of rice, but the whole world. He said that I want to engage in rice, which is the staple food and the pulp (from phenomenon to essence). He said to the villagers: there is no rice in everyone's bowl. It should be us who study agriculture who say sorry. It is better to plant another fertilizer. I must find a good seed.
Man is a seed. Everyone should be a healthy seed. Be healthy physically, mentally and emotionally. Only when seeds are healthy can they take root and sprout and bear fruitful fruits. In Yuan Longping's mind, the dream that haunted him all his life appeared. This is a magical dream. The ears of rice are so long and the grains are as big as peanuts, so you look full. To this end, he used his whole life's courage and strength to pursue it. This is a dream of enjoying the cool under the grass. ?

Dream of enjoying the cool under the grain? In today's people's eyes, it is incredible to have a full meal, but most people born before the 1980 s have had unforgettable experiences. It can be said that few people can eat rice without other miscellaneous grains when they are young. In the early 1960s, due to natural disasters and other reasons, my grandfather, grandmother and grandfather all starved to death. My grandfather went to the city to see a doctor and fell down before he got to the hospital. The doctor said: this is not a disease! Obviously hungry. Therefore, we sincerely respect Yuan Longping and affectionately call him Grandpa Yuan, and thank him from the heart. Food is the most important thing for the people, and agriculture is the foundation of the country. No matter who it is, having a full meal is the top priority. It is unthinkable if you have no food to eat. ?

Adhere to the truth, seek truth from facts, and do not blindly believe in authority. ?
Yuan Longping first studied sweet potatoes and grafted them with tomatoes. Teacher Jin Xuenong said: You only have quantitative change, not qualitative change, and you can't pass seed inheritance. After a few months, take out the seeds from tomatoes or tomatoes, sweet potatoes or sweet potatoes. Acquired inheritance theory is not established, and Michulin's acquired inheritance theory, which puts philosophical views on genetics, is also unsuccessful. A large number of experiments proved that the experiment of grafting the first generation seeds was successful, but the second generation seeds failed. ?
Practice and fallacy of acquired genetic theory? When Yuan Longping handed the paper report to the director of the breeding group, Director Wang said: We just won the prize for this achievement, and you said that our experiment failed. Doesn't that mean we cheated others? You even dare to doubt and deny the Soviet expert Mi Qiu Lin. Wang Gui burned his paper, but I didn't expect stubborn Yuan Longping to post his backup paper on the school wall newspaper for everyone to see. He said that we should not deceive ourselves, let alone others, be kind and honest. His research completely overturns the theory of "asexual hybridization" of Michulin and lysenko, and infers that rice also has the advantage of hybridization.

Has the theory of acquired heredity failed? We know that maize and wheat can cross successfully by chromosome doubling, but rice can't. The most reliable and effective method of hybrid rice is artificial emasculation. There are more than 100 flowers per panicle of rice, and each flower is hermaphrodite. The seeds obtained by artificial emasculation are quite limited. This is the ceiling of hybrid rice. American geneticist Shannon announced the death penalty of hybrid rice in advance. Even with the advantages of hybrid rice, it is impossible to produce seeds on a large scale in the future. ?
