CCTV News: A hundred years have passed, but youth has not changed. Looking back at the long river of history, generations of young people have always resonated with the motherland, time flies forward, and youthful figures are always striving for progress. CCTV News Channel has launched a series of reports "Struggle in the Best Youth" to witness the brightest background of youth. Nanniwan was once a wasteland on the Loess Plateau. Doing it yourself and having enough food and clothing is the spirit of self-reliance and hard work that has turned it into "the good Jiangnan of northern Shaanxi". Watch the first episode "The Land Reclamator is in youth! 》

In the greenhouse cabin of the Institute of Botany, Chinese Academy of Sciences, the scientific research team is conducting research on the seedlings of the forage crop, alfalfa, but these "grasses" have made great achievements. According to Le Jie, a researcher at the Institute of Botany, Chinese Academy of Sciences, although it is a "grass", it has high protein and can replace soybean feed crops. Every year, one of the functions of imported soybeans in my country is to squeeze soybean oil, and the remaining soybean meal is used as feed. Alfalfa is a very good forage, and it can be used to grow forage, raise cattle and sheep in saline-alkali land, so that people can eat meat. Be sure to hold your job in your own hands. At present, we must adhere to the fine tradition of self-reliance and hard work.

Self-reliance, hard work, and a spirit that is renewed over time. During the War of Resistance Against Japan more than 80 years ago, 40,000 patriotic young men braved artillery fire and rushed to Yan'an from all over the country to pursue the dawn of saving the country. Lejie's grandfather, Le Tianyu, is one of them.

Faced with difficulties, young people in the border areas broke through the blockade with the determination to fight the war to the end. In the Yan'an Revolutionary Memorial Hall, a small grass is on display. There was a shortage of paper in the border area. Hua Shoujun, a young man from Zhijiang University in Hangzhou, used the grass from Yan'an to make paper and currency; what was even more serious was the shortage of food and cloth, and the military's shoes were so broken that they exposed their toes.

In order to solve the food shortage, the Central Committee of the Communist Party of China proposed the idea of ​​military cultivation and military farming, which can create miracles in the barren Loess Plateau? Yan'an Academy of Natural Sciences sent a scientific research team to find a breakthrough, and led the team by Le Tianyu, director of the Department of Biology. They collected more than 2,000 plant specimens and found out the vegetation and climatic conditions in various places.

"Do it yourself, have enough food and clothing" From the military commander to the groom and the knights, everyone worked together for production. Arsenals, textile factories, and granaries all came from scratch. The Communists forced the barren "muddy depression" into "the good Jiangnan in northern Shaanxi", laying the foundation for the victory of the War of Resistance Against Japan. Hua Xiaoning, son of Hua Shoujun, winner of the title of "Hero of Labor" in Shaanxi-Gansu-Ningxia Border Region, said: "I have never heard my parents say that life was very hard at that time. They just knew that they had to give their youth and passion to achieve beautiful ideals."

Self-reliance, hard work, and carry forward the spirit of Nanniwan. At China Agricultural University, Lotteyu's alma mater, a wasteland reclamation team spanned half a century, dedicating their youth to the transformation of soil and alkali.

Located in Quzhou County, Hebei Province, the Huanghuai Plain, in the 1960s, one-third of the arable land here was saline-alkali land, and people often had to rely on state relief for food. In 1973, seven teachers from Agricultural University came here to find a way out for the saline-alkali problem in drought, flood, and saline. The people were worried at that time that young people from Beijing could survive the hardships of land reclamation? According to Zhang Hongyan, deputy director of Quzhou Experimental Station of China Agricultural University, after the teachers came, they took out the grain book and put the grain book here, which means they will not leave, and when will the alkali be cured and leave.

In the era of buying grain based on capital, paying grain is equivalent to suppressing all your wealth. Young agrociologists and farmers joined forces to dig canals to control soil, allowing wheat and corn to grow on the barren land, and allowing the people to have self-sufficient food.

The land reclamationists are in their youth, and they are striving with each generation! Since 2009, the land reclamation team sent to Quzhou County has become China's first science and technology courtyard. Graduates from Agricultural University have farmed, managed grain, composted, and top dressing, and put "papers written in the fields." Jiao Xiaoqiang is one of the earliest graduate students from the Science and Technology College, and has now grown into the youngest associate professor. After 15 years of rooting in Quzhou, his skin has been sunburned. Jiao Xiaoqiang, associate professor at Quzhou Experimental Station of China Agricultural University, said: "This kind of 'self-investing' is a tempering of one's own soul. We also have an important evaluation standard for graduate students: if this student is invited by villagers to dinner, it means that this young man does a good job in the village, can integrate with the farmers, form technology that farmers are willing to accept, and can bring real benefits to the farmers."

With the continuous efforts of students from Agricultural University, Quzhou County has achieved a breakthrough in the yield of 1 ton of grain crops per mu, setting a model for increasing yields for the country's medium and low-yield fields. At present, students from Agricultural University are challenging higher grain output.
