If I am not at home, I must be in the experimental field; If you are not in the experimental field, you must be on your way to the experimental field. This is a word widely circulated by Yuan Longping, and it is also a portrayal of his real life.

The first experimental field in Yuan Longping is located in Anjiang Agricultural School, located in No.7 field in the Middle Ages. 1on April 30th, 968, more than 700 sterile seedlings were carefully planted in this field by Yuan Longping and his assistants. However, one night after 18 days, all these sterile seedlings were pulled out, and I don't know who did it.

In order to speed up the propagation of aseptic seedlings, Yuan Longping turned its attention to the south where the sunshine time is longer and the temperature is more suitable. Guangdong, Hainan, Fujian ... Many places suitable for cultivating hybrid rice have opened up his experimental fields, and Yuan Longping's footprints have been left on the ridge and between the paths.

1979 In May, Welch, the general manager of the famous American ring seed company, visited China, and the seed company of the Ministry of Agriculture gave him 1.5 kg of hybrid rice. Welch took it back to China, tried to plant it that year, and immediately increased the output. By 2005, the United States had cultivated 800,000 mu of hybrid rice, with an average yield of more than 600 kilograms per mu, which was 25%-35% higher than that of local improved varieties.

In Vietnam, by 2005, the planting area of hybrid rice was nearly 6.5438+million mu. Hybrid rice has been tried in the Philippines, Indonesia, Bangladesh, Pakistan, Ecuador, Guinea and other countries.
