"Foreign forage" should not be introduced blindly

Introduction: three years ago, a project with an investment of 60 million yuan and the introduction of more than 80000 mu of American alfalfa was implemented in Hulunbuir prairie in Inner Mongolia; three years later, when other forages here thrive, nearly 70000 mu of Alfalfa died The first attempt of planting alfalfa in large area in Hulunbeier League failed What is the cause of the mass death of Alfalfa? Ma Zhiguang, a technical consultant of the company and researcher of the Grassland Research Institute of China Agricultural University, said that the seeds themselves are free of problems, and the main cause of death is the external climate environment At present, the cause of death is that there was too little snow in the last winter and the temperature was too low, which is rare in the past years This spring, when the grass returned to green, there was a rare late spring cold, which caused the root system to be frozen to death, resulting in the death of alfalfa Zhao Laixi, an associate researcher from the Grassland Research Institute, thinks that the death of alfalfa is also related to excessive harvesting According to his investigation, the last harvest last year was too late, and there were too many harvests in some places, resulting in insufficient storage of nutrients needed for alfalfa to survive the winter and death in bad weather But the cause of Alfalfa death is not just that Jiang Jingchun, the former head of the grassland station in Ewenki, said that when Zhongxin alfalfa company introduced these alfalfa, it only carried out a one-year plot test under the greenhouse conditions, without intermediate test, and then carried out large-scale planting This practice is against the laws of science The minimum test period should not be less than 3 years for the introduction of foreign varieties Can alfalfa be planted in Hulun? What is the way to develop the grass industry in Hulun League? Zhao Laixi said that there is a range of adaptability of alfalfa, and the geographical and climatic conditions in Hulun League have reached the edge of its adaptation range, which will cause great losses in case of any abnormality It's best to cultivate local seeds first Jiang Jingchun said that efforts should be made to develop the rich resources of Wild Alfalfa in Hulun pastoral area, because it is more suitable for local conditions In addition, we should actively develop other legume forages, such as Astragalus adsurgens, sweet clover, etc., and constantly increase the proportion of legume forages in the grassland Experts who have been engaged in grass industry research for many years said that Hulu League should reflect on the failure of the introduction of American Alfalfa at the cost of 60 million yuan at least in exchange for several lessons: first, it should be recognized that grass planting is a long-term project, and any act of quick success and instant profit will only damage the development of grass industry; second, government departments must be careful in the process of attracting investment, and strictly review the project Caution, we should make repeated research on the project and never introduce it blindly; it is a good thing for the third enterprise to participate in the ecological construction, but the enterprise aims to pursue profits, so the government departments should play a role of macro-control and supervision after the implementation of the project, so as to overcome various adverse actions of the enterprise (author:) share to feed Weibo share to:
