Yuan Longping planted sea rice-haywire

Yuan Longping has developed a "sea rice". At the 2016 world Life Science Conference held recently, Yuan Longping introduced the "sea rice" which is being explored". It is understood that the day before the Qingdao city established the "Qingdao water rice research center", this is the first national water rice research and development center, Yuan Longping served as chief scientist and director of the center. The center plans to achieve a goal of 200 kg per mu of seawater rice per mu in 3 years. Yuan Longping hopes to cultivate more than 300 kilograms of sea rice per mu in the future. Set this goal, Yuan Longping said, planting rice need fertilization, irrigation, pest management, which need cost. At present, the yield of seawater rice is not high, and the yield per mu is only about 100 kg, which is semi wild. Farmers grow, even the cost can not be returned, enthusiasm is not high. But if you can increase to 300 kilograms per mu, a sea of rice bargain. Yuan Longping said that the current "seawater rice" experiment in Qingdao is still advancing, and the future is expected to be able to irrigate with more saline and alkaline water. "There are over 10 million mu of saline land in China, no crops, there are tens of millions of acres of beach, if you use the country to promote one hundred million acres of sea rice, 300 kilograms per mu, will increase 30 billion kilograms, equivalent to the annual rice production in Hunan province." Yuan Longping believes that seawater rice has a promising future. Yuan Longping introduced, the key is to promote the rice water enhance the salt concentration, divided into two routes: one is breeding in conventional breeding, the characteristics of salt transfer to the high-yield varieties above; another is the molecular techniques, the salt resistance gene cloned transfer to high product. He also believes that the molecular technology is better, but more difficult. Yuan Longping also said that some foreign scientists are also engaged in the research and development of seawater rice. But China has a unique resource advantage in this field. The wild sea rice with strong alkali resistance, strong disease resistance and strong vitality in the estuary of big rivers in South China provides valuable resources for researchers. In an interview, Yuan Longping also responded to the question of "high yield and low quality" of hybrid rice. Some people think that hybrid rice, though high in yield, is often of poor quality, and even some consumers prefer foreign high-quality rice. Yuan Longping said that hybrid rice at the same time to achieve high yield and high quality, it is difficult, but the yield and quality is not antagonistic contradictions. Yuan Longping said, "some people have a one-sided view of hybrid rice, think high yield is not high quality, before indeed some hybrid rice quality is general.". But in the last century, the first thing to solve is the problem of food and clothing, and we must give priority to production." Yuan Longping said, living standards improved now, people are not satisfied with eating, but also eat well, we have changed the strategy, both high yield, but also good quality, but not for the cost of production for quality. "We have bred a new hybrid rice rice" super excellent thousand ", the quality can be compared with the market on a 80 yuan a pound of Japanese rice. Japanese businessmen came to us specially, and sampled and tested, and commented that they have elasticity, chewing head, and good taste." Yuan Longping said proudly. He believes that some high quality rice prices are very high, there are reasons for market speculation, usually people can not afford. He also stressed that Chinese people are more,.

袁隆平种出了“海水稻”在近日举行的2016世界生命科学大会上,袁隆平介绍了正在探索种植的“海水稻”。据了解,青岛市日前成立了“青岛海水稻研发中心”,这是国内首个国家级海水稻研究发展中心,袁隆平担任该中心主任和首席科学家。该中心计划在3年时间内,实现海水稻种植亩产突破200公斤的目标。而袁隆平希望未来能够培育出亩产300公斤以上的海水稻。之所以定下这个目标,袁隆平说,种水稻需要施肥、灌水、治理病虫害,这些都需要成本。目前海水稻产量不高,亩产只有100公斤左右,是半野生状态。农民种了连成本都收不回,积极性就不高。但如果能提高到亩产300公斤,种海水稻就划得来了。袁隆平说,目前在青岛的“海水稻”实验仍在推进,未来期望能够用更咸更碱的水灌溉。“全国有十几亿亩的盐碱地没种庄稼,还有几千万亩的滩涂,如果利用起来全国推广一亿亩海水稻,每亩300公斤,将增收300亿公斤,相当于湖南省全年的水稻产量。” 袁隆平认为,海水稻很有发展前途。袁隆平介绍,海水稻推广的关键是要提高其抗盐浓度,在育种方面分两个路线:一个是常规育种,把抗盐的特性转移到高产品种上面来;另一个是分子技术,把抗盐的基因克隆出来转移到高产品种上去。他还认为,分子技术效果更好,但难度较大。袁隆平还说,国外有些科学家也在从事海水稻的研发。但中国在这一领域具有得天独厚的资源优势。在中国南方大江大河的入海口,生存着耐碱性强、抗病性强、生命力强的野生海水稻,为科研人员提供了宝贵的资源基础。接受采访时,袁隆平还回应了对杂交水稻“高产低质”的质疑。有人认为杂交水稻虽然产量高但往往质量不高,甚至有些消费者偏爱外国优质米。袁隆平表示,杂交水稻同时实现高产和优质,难度很大,但产量和质量不是对抗性的矛盾。袁隆平说,“有人对杂交水稻有片面看法,认为高产就不优质,以前确实有些杂交水稻品质一般。但要看到,上个世纪,首先要解决的是温饱问题,必须把产量放在优先地位。”袁隆平说,现在生活水平提高了,人民不满足于吃饱,还要吃好,我们也改变了战略,既要高产,又要优质,但不以牺牲产量为代价来求优质。“我们已经培育出的杂交水稻新品种大米‘超优千号’,品质可以与市场上一种80元一斤的日本米媲美。日本商人专门来找我们,并取样检测了,评价说有弹性有嚼头,口感很好。”袁隆平自豪地说。他认为,一些优质米价格非常高,有市场炒作的原因,通常老百姓吃不起。他还强调,中国人多,人均耕地少,我们要高产优质,不能低产优质,保障粮食安全就要提高单位面积产量。相关的主题文章:
