< p > before the saline alkali soil that could hardly survive weeds, after applying an acid-base balance nursing agent, not only a href= "http://m.pmae.cn/news/index_c.asp" > cotton > /a >, but also more than 150 kg of cotton yield per mu, only 100 kilograms less than that of ordinary cultivated land. < /p >
< p > recently, the reporter followed 30 experts and experts from the Xinjiang Association for science and technology, the Xinjiang Institute of ecology and geography and the Xinjiang soil and Fertilizer Association organized the "grassroots science popularization activities of 100 million people" and the "Symposium on saline alkali soil improvement (acid-base balance nursing agent) on-site observation", and came to the eighth division Shihezi, Shawan County and Kuitun city for field inspection. < /p >
< p > at a cotton field in the 133 regiment of the eighth division of the regiment, the reporter saw a demarcation line dividing it into two. The South was luxuriant, and there was already a blooming peach, but the North was deserted. Only a few weeds and dwarf cotton could be seen, and a sheet of white salt covered the surface. < /p >
< p > "before the cotton field was changed and fertilized, what method was used, and there were few cotton growing. This year, after the application of acid-base balance nursing agent in the south, the emergence rate of cotton reached more than 60%." Jia Juncheng, a technician of the agricultural extension station, said. < /p >
< p > it is understood that the acid-base balance care agent is developed by Hongdu Jia Ye Biotechnology Co., Ltd. in Urumqi. At present, the chemical modifier has reached tens of thousands of Mu in our area. "The average cost per mu is more than half of that of ordinary saline alkali land, and the effect is much faster." Jia Jun said. < /p >
< p > reporter learned from this inspection that < a > Xinjiang < /a > is a large area of soil salinization, and 32.1% of the existing cultivated area is threatened by saline alkali. Salinization has become a major obstacle to agricultural development and sustainable development in our region. < /p >
< p > according to Tian Chang Yan, director of the Xinjiang Institute of ecology and geography and the director of Xinjiang soil and fertilizer society, in recent years, researchers in Xinjiang have been exploring various ways to improve saline and alkaline land. Previously, the traditional method of digging and draining the alkaline ditch and the large scale salt washing irrigation has been used before, but it will take several years and repeated several times to make the land suitable for farming. In recent years, water resources in Xinjiang are becoming more and more scarce. Researchers are also trying to improve the biological methods and use some halophytes to improve the soil of saline alkali soil. < /p >
< p > Da Nagasahiko said that compared with the above methods, the newly developed chemical improver uses the chemical principle to reduce pH value of soil and improve the soil saline and alkaline environment by neutralizing the acid and alkali components in saline alkali soil, so as to achieve the requirement of plant growth. In recent years, the cost of the improver is small, and its effect is relatively fast. < /p >
< p > at present, there are 265 million mu of cultivated land in Xinjiang, of which 90% of the "a" href= "http://m.pmae.cn/news/index_s.asp" > saline alkali land < /a > can not be developed because of lack of water. "The development of saline soil agriculture should be an important measure for Xinjiang's economic construction and ecological establishment, and also a new growth point. It will have an important impact on Xinjiang's ecological restoration and environmental protection." Da Nagasahiko said. < /p >
