    You see, it was a white, salt-alkali area with a pH of about 9 and a salinity of 0.6%. If today's results exceed 500 kg, it will be a relatively large breakthrough. On the 24th, Qi Shaowu, director of Hunan Hybrid Rice Research Center, who was waiting for the results, turned over the straw after harvesting to check the rice loss rate while reporting to science and technology daily
    the production site in the right-center flag Bayangar Sumu, is the new launch of The Inner Mongolia Xing UNITA salt-alkali land comprehensive utilization demonstration base, but also soda-type saline rice as an improvement base, covers an area of about 1000 acres, mainly used for the introduction of salt-resistant plant species, side test demonstration, side promotion. Among them, salt-resistant rice cultivation, with an area of about 600 mu, through cooperation with Hunan hybrid rice research center, to carry out salt-alkali-resistant rice varieties resource identification, introduction observation, variety screening display expansion, and fertilizer testing, improver testing. At present, there are more than 600 resources of self-selected and foreign-introduced varieties.
    worth mentioning is the "pH of about 9 pH, 0.6% salinity" of the property, which makes it a "high match" for saline land. Zhang Yu candle, deputy director of Hunan Hybrid Rice Center, explains that there are two main categories of saline land in China. One of them is the northeast inland soda saline, the main harm lies in alkali. Alkaline can lead to soil plate knots, non-permeable water, greatly affecting the absorption of fertilizer and other nutrients. Usually, pH is higher than 8, it is difficult to grow crops, and China has more than one billion acres of saline land. In addition, high salinity will also destroy the fertilizer absorption and penetration system, easy to lead to rice seedlings, seedling death, not strong and other problems. "Previously, Yuan Longping
    set a target of 9 pH in saline land, or more than 300 kg per mu when the salinity is 0.6%." Zhang Yu candle said.
    clearly, this "two-for-one" conditions, this base at the same time "owned." Zhang Yu candle said that the vast majority of the northeast salt-alkali land pH value of about 8, therefore, the rice varieties that can be grown here, basically can "eat" most of the salt-alkali soil in the northeast, which is the value of this scientific research. Yuan Longping believes
    the use of rice hybrid advantages, can greatly improve its salt-alkali resistance, which has become his "heart in recent years."
    with a major special project in Hunan Province, Hunan hybrid rice research center in Inner Mongolia "landed." Through hybrid technology and effective salt-resistant alkali gene, variety resource utilization and other means, screening suitable for a variety of salt-resistant soil varieties. At the same time, many improvements have been made in soil and farming, such as the use of physiologically acidic fertilizer and pH, water and fertilizer management, planting management and so on through measures to preserve water and drainage.
    "We hope that in about 3 years, we can find a complete set of saline varieties improvement and cultivation technology, in the Xing UNITA region and even the entire north-east region has a certain source of saline land, large-scale promotion and replication. Today, we also grow more than 600 resources and combinations in higher salinity soils. We estimate that about 15% of these varieties will work here. We will also do further identification of the resistance of these varieties, next year there should be more suitable for the northeast salt-alkali varieties appear. Zhang Yu candle said.
    Qi Shaowu revealed that China will set up a salt-resistant rice innovation research center, led by Hunan Province, to increase salt-alkali varieties selection, soil improvement and industrialization research. At present, Hunan Hybrid Rice Research Center has established salt-alkali rice research bases in Xing UNITA, Jiangsu, Hainan Wenchang, Jilin Da'an, Guangxi Northwest Sea and other places.
    And the final result of this large-scale test production, also became Yuan Longping team for the 70th anniversary of the founding of New China sent a special congratulatory gift: measured mu yield of 508.8 kg, more than Yuan Longping
    's "and the grid line."
