In order to increase the yield per mu, a famous slogan was put forward at that time, "crossing the Yellow River, the Yangtze River and the outline". The grain output in the areas south of the Yellow River and north of the Yangtze River should reach 500 kg/mu. The grain yield per mu in the area south of the Yangtze River should reach 800 Jin. When the yield per mu reaches 500 kg, cross the Yellow River and 800 kg cross the Yangtze River. After reaching 800 kg, it is called Chaogang. This is a plan made in the agricultural plan decades ago. 1964, Yuan Longping began to study hybrid rice. Through unremitting efforts, the yield per mu was 20001400kg, 20041600kg, 20 121800kg and 20 14 years. Yuan Longping's dream of pursuing high yield has come true step by step.

"Developing hybrid rice to benefit people all over the world" is Yuan Longping's lifelong pursuit. Under the impetus of our government, China hybrid rice technology has been popularized in more and more countries, and its trial planting demonstration in Southeast Asia, South Asia, South America, Africa and other countries has achieved great success. Hybrid rice has not only solved the problem of eating in China, but also played a positive role in benefiting the world. If the harm of natural factors is excluded, the yield of hybrid rice will be higher. A year ago, the rice was ripe and the golden millet was very good. People are just happy for a few days. Because the rice is full, flocks of sparrows and birds will fly to harm people. For example, some of the rice above is often eaten completely, but the lower part can't be eaten. The above yield is measured by sparrow damage. As I remember, in the 1970s and 1980s, the traditional rice varieties planted in my family included "white millet", "red millet", "800 grains", "gold covered with silver" and "japonica rice", all of which were reserved for myself, and the yield was very low, generally between 300 and 400 kg.

Bai Shu, "The neck stalk is high, but it is very soft. It is easy to break when the wind blows, resulting in low yield. Farmers gave up after two years." Redmi, Redmi in the red song "Redmi Pumpkin Soup", 1980 was introduced to Guizhou from Jiangxi, and some farmers tried planting. The ears of rice are very similar to "white millet". They taste good, but they are easy to get sick. If a few rows of rice are planted, the whole field will be infected. "Eight hundred grains" was the rice variety promoted by the state at that time. It is said that there are 800 grains of rice, but some farmers just don't believe it. When the rice was ripe, they picked a few drops of millet and sat and counted slowly. As a result, there are not 800 capsules, and 200 capsules at most will be great.

Later, due to various reasons, people planted "gold-coated silver" and "japonica rice" only for one or two years. Before the popularization of hybrid rice in the 1980s, the farmers on our land were mainly "gold covered with silver" and "japonica rice". The yields of these two rice varieties are higher than those of white rice, Redmi and BaBaiZi. Farmers have been planting these two kinds of rice for five or six years.
