Shanghai has developed the only water-saving and drought-resistant rice "standard variety" in southern rice region.
The Shanghai Academy of Agricultural Sciences announced on the 16th that Shanghai agricultural scientists have bred the only upland rice regional trial control variety in the southern rice region and the first japonica upland rice variety approved by the state in the southern rice region, and built the most perfect rice drought resistance identification and evaluation system and germplasm resources platform in China. Shanghai has become the main research base for water saving and drought resistance of rice in China. According to Gu Xiaojun, vice president of the Shanghai Academy of Agricultural Sciences, the "Zhonghan 3" selected by scientists here is the first upland rice variety approved by the state in southern China.

Water-saving and drought-resistant rice variety "Hanyou 3" has high yield and good seed.
Rice is high-yielding, but afraid of thirst; upland rice is drought-tolerant, but its yield is slightly lower. Shanghai rice experts skillfully integrated the advantages of high yield of rice and drought tolerance of upland rice into one grain of rice to produce the world's first water-saving and drought-resistant hybrid rice "Hanyou 3". The author saw a few days ago that the mature "Hanyou 3"tired" bent: 110 grains per panicle, the yield per mu is better than conventional rice, and the rice field saves more than 50% of water. Xinmi can be listed in Shanghai at the end of the month. Tested by professional departments, the rice quality of "Hanyou 3" has reached the second-class high-quality rice standard of the Ministry of Agriculture.

700,000 mu rice in Qing 'an adopted water-saving and high-yield technology of drought cultivation control irrigation in cold region
The water-saving and high-yielding technique of controlled irrigation for dry-cultivated rice in cold region was successfully tested in Qing 'an. This year, the county has 700,000 mu of rice to promote this technology. According to experts 'calculation, about 450 cubic meters of water per mu can be saved, 11.2 yuan of pumping cost can be saved, and the average yield per mu can be increased by 22 kg. In recent years, Qing 'an has reduced the irrigation water consumption per mu from nearly 1,000 cubic meters to 500 cubic meters by carrying out the trinity method of "engineering water saving, mechanism water saving and technology water saving." In 10 years, the paddy field area has grown from 640,000 mu to 1.17 million mu, accounting for half of the cultivated area.

Water-saving and high-yield rice produces jasmine fragrance
It has become a reality to put on shoes to go to the fields and save water to grow rice. A team led by Luo Lijun from Shanghai Agrobiological Genome Center created the world's first early hybrid rice, "Huhan 1A", and made a new breakthrough. Hanyou 3 has been approved, and the actual yield per mu has exceeded 500 kg for the first time under the condition of saving 50% of water resources. In the early rice hybrid research in Shanghai, it took scientists 10 years to screen 10,000 resources and obtained more than 100 drought-resistant resources as parents for breeding. "the characteristic of hybrid rice is high yield, just like that made by

Biological water-saving technology of rice
Biological water saving technology refers to the use of the physiological and genetic potential of organisms to obtain more output under the same water conditions. Although the research is difficult and the degree of development is low, the investment in the application is small and the benefit is high. Using a large number of germplasm resources obtained for many years, rice breeders selected a number of varieties with strong drought resistance by means of inter-variety hybridization, systematic breeding and introduction and evaluation, and applied genetic engineering to the breeding of new varieties. continue to provide new hybrid rice combinations with high quality, strong drought tolerance and greater biological potential for water-saving cultivation.

How to make enterprises bear the burden of saving grain
If the column is opened, China's grain production will have a bumper harvest in successive years, and at present, grain production needs to be basically balanced. However, a large population and little land are the basic national conditions of our country. The constraints of natural resources such as fresh water and ecological environment and the impact of climate change are becoming increasingly obvious, and it is becoming more and more difficult to stabilize grain production and increase production.
