Help farmers stabilize production, reduce carbon reduction, science and enterprise cooperation- "three accounts" perspective water saving water -saving drought and rice
Author:Xinhua News Agency Time:2022.09.29
In the golden autumn season, the autumn harvest of the Jianghuai land is. A harvester shuttled in the rice fields, and many large grain households lamented, "This season's grain harvest is not easy!"
As the main grain crops in the southern region of my country, the amount of water requires a large amount of water. Once the high temperature is not superimposed with insufficient water supply, the output will be affected.
On September 28th, at the 2022 National Water -saving Drought Rice and Drought Rice Drought Rice Drought Rice Rice on -site Observation and Technical Symposium held in Hefei City, Anhui Province, the reporter noticed that unlike traditional rice with a large amount of water, water -saving drought -resistant rice is not only strong, but also tolerant. The output is guaranteed. In the water -saving drought -resistant rice test base of Huaixi Modern Agricultural Demonstration Park, Niuzhai Village, Gangji Town, Hefei, a large grain and breeding experts gathered to see the water -saving drought -resistant rice from the "three accounts".
The first book: Grain and Nong Calculate the income increase
Looking at the heavy valley ears and waiting for the harvest, Chen Lei, a large grain farmer in Niubai Village, Gangji Town, Changfeng County, Hefei, said that compared with other rice varieties, planting water -saving drought and drought. Tian can save at least 30 % of water. "For the relatively tight water resources of water resources, this is less water, which not only saves water costs, but also saves the electricity fee required to use the pump machine to pick up water. Yuan. "Chen Lei said.
The "post -90s" grain households planted 300 acres of water -saving drought -resistant rice last year and expanded to 1,000 acres this year. In his opinion, "reducing damage is increasing income." Chen Lei said that although the cost of seeds is higher, it is made to earn food to receive food and sell well.

According to Luoli Jun, chief scientist at the Shanghai Agricultural Biology Center, the average yield of water -saving drought -resistant rice can reach 650 kg to 700 kg. Luo Lijun said that water -saving drought -resistant rice can not only "live broadcast and dry tube" like wheat, but also "live broadcast drought". Planting water -saving drought -resistant rice can also bring income to farmers.
Second book: Field Management Topoly Slotting Carbon reduction account
At the conference site, Luo Lijun introduced that water -saving drought -resistant rice has promoted about 1.5 million acres in Anhui this year. In Chen Lei's view, the continuous promotion of water -saving drought -resistant rice can also be benefited from the low demand for fertilizer. "The average amount of fertilizer per acre is about 30%compared to the traditional rice fields. One stroke. "Chen Lei said. In addition, the amount of insecticides and herbicides for water -saving drought -resistant rice is less, which helps reduce agricultural pollution.
Luo Lijun said that according to the study of water -saving drought -resistant rice in Jinshan District, Shanghai, water -saving drought -resistant rice was invested by 76%lower than conventional rice per mu. And 71%.
The decrease in the amount of gas emissions of the rice fields is also the focus of attention to the on -site observation and technical seminar of water -saving drought -saving rice. Zhou Sheng, deputy director of the Shanghai Low -Carbon Agricultural Engineering Technology Research Center, said at the seminar that through measurement, it was found that water -saving drought -resistant rice can reduce methane emissions by 90%compared with ordinary rice.
Third account: Science and enterprise cooperation calculates the innovation account of the seed industry
At the conference, Luo Lijun stated that the production of rice is high but requires large amount of water, the production of drought rice is low, but the demand for water is small. Research and develop water -saving drought -resistant rice.

Rice breeding "one sword for ten years". Since the end of the 20th century, the Rollene Army led the scientific research team to combine the high -quality characteristics of modern rice with the drought resistance and resistance characteristics of drought rice, and finally developed water -saving drought -resistant rice through hybrid breeding innovation. The "Creation Protection and Research and utilization of rice genetic resources" project jointly completed by many scientific research institutions in their team, and won the first prize of the 2020 National Science and Technology Progress Award.
"Good seeds need to be promoted." Wang Huachun, head of the production and technical department of Anhui Fengda Seed Industry Co., Ltd., who undertake water -saving drought -resistant rice transformation, said that through the establishment of demonstration fields, holding observation meetings, "economic accounts" for farmers, etc. "Science and technology species" can be widely planted in farmland.
It is understood that Hefei is committed to creating the "capital of the seed industry", which will incorporate the development of modern breeding industry into the city's strategic emerging industry planning. By planning the establishment of a special fund for modern seed industry, the seed industry will continue to burst into innovation vitality. (Reporter Wang Haiyue, Shui Jinchen, Liu Xiaoyu)
