In September, in the farmland of Shandong Peninsula, there was a scene of bumper harvest. In a paddy field 20 kilometers from the mouth of the Yellow River to the sea, Mao Jianmin, a villager of 28 villages in Yongan Town, Kenli District, Dongying City, Shandong Province, is working in the field with several villagers. The rice in the field grew well. Although it was not yet harvested, Mao Jianmin was busy cutting rice ears in the field with sickles. It turned out to be a paddy field for breeding.
Cutting rice spike
Nobody would believe that, just a few years ago, there were almost all saline-alkali desert beaches that were barren of grass. Villagers said that there were more than 1,000 villagers in 28 villages, but since the 1950s and 1960s, the local land has been seriously saline and alkaline, and can not continue to cultivate. In order to make a living, the villagers have moved away one after another, and now there are only more than 100 people left.
Saline alkali soil
The turnaround took place in 2014, when the village transferred more than 1,000 mu of saline-alkali land to a company in Qingdao as a whole. Through soil improvement and breed selection, the company planted Saline-Alkali-Tolerant seawater rice on the barren land. In the past six years of cultivation, the growth has been better and better year by year. ?
Seawater rice planted in saline-alkali soil can yield 1,000 kg per mu this year, while in the local area, the yield of ordinary rice per mu is only about 1,300 kg.
In Qingdao, hundreds of kilometers away from Dongying, researchers in the laboratory of the Seawater Rice Research and Development Center are busy in the research and development of salt-tolerant rice varieties. ?

Over the past seven years, the yield of salt-tolerant rice per mu has been continuously increasing, and the trial planting has been fully launched. In 2019, nearly 20,000 mu of salt-tolerant rice materials were planted in five major saline-alkali areas of China, and 23 rice materials participated in this years regional planting experiment. More experiments are still under way.
The Saline-Alkali-Tolerant rice irrigated in the experimental field is not ordinary water, but dilute salt water after strict mixing. Only through layer-by-layer testing and selection of materials, will they enter a large-scale demonstration and promotion.
Yuan Longping, academician of the Chinese Academy of Engineering and director of the National Hybrid Rice Engineering Research Center, said: We plan to succeed in developing 100 million mu of seawater rice. If it is extended to 100 million mu, 300 kg per mu, 30 billion kg more rice can be produced and 80 million more people can be fed.

Although the land lost and recovered in 28 villages has been transferred out, the villagers are still as meticulous and hard-working as their own fields. Not far away, 800 Mu saline-alkali tolerant late rice experimental field has begun to fill, more than a month later will also usher in the harvest season. In the green paddy fields, the harvest is getting closer and closer.
Over the years, the Party and the state have attached great importance to grain production. As of 2018, Chinas grain production has stabilized for seven consecutive years at more than 1.2 trillion jin. According to the Ministry of Agriculture and Rural Areas, autumn grain has been harvested one after another in late September. The situation of autumn grain production in 2019 is generally better. In addition to local drought and flood disasters, crops in most areas are growing well and showing a trend of increasing production. In addition, summer grain and early rice have achieved a bumper harvest. If there are no major natural disasters in the later period, it will be a bumper harvest. Harvest year.
Years of production can not be separated from the power of science and technology. Agricultural science and technology are changing the backward mode of production. In the future, science and technology will change not only the technology of agricultural production, but also the popularization of science and technology will change peoples production concept more profoundly. In the future, the relationship between people and land and nature will become more harmonious, and our abundance will increase. The harvest will become more secure.
