水稻旱种是1956年国营芦台农场开始在沼泽化潮土和1957年军粮城稻作试验站在滨海盐土上试验成功的。当时由于草的问题没有解决,未被重视起来。1972年以来,北方各地连年干旱缺水,原有稻田面积急剧下降,稻谷产量锐减,造成吃大米难的问题。中国农科院作物所的研究人员有鉴于此,于是便去北京市大兴县同农民结合,又进行了水稻旱种研究并获得可喜成功。由于水稻旱种是在干早缺水情况下闯出来的一条种稻新路子,因此受到领导和群众的欢迎。到1982年,辽宁、河北、山东、河南四省和北京、天津两市共早种水稻11万亩。根据当地自然
Cultivation of rice is the state-owned Lutai Farm began in 1956 in the swampy soil and 1957 Junliangcheng rice test station in the coastal salt soil test success. At that time, the problem of grass was not solved and was not taken seriously. Since 1972, successive years of drought and water shortage in various places in the northern part of the country have resulted in a steep decline in the area of paddy fields and a sharp drop in paddy production, which has caused the problem of eating rice. In view of this, researchers from the Crop Research Institute of Chinese Academy of Agricultural Sciences went on to combine with peasants in Daxing County, Beijing, and carried out research on dry cultivation of rice and achieved gratifying success. Since dry cultivation of rice is a new way of rice that has been found in dry and dry conditions, it has been well received by leaders and the masses. By 1982, Liaoning, Hebei, Shandong, Henan and Beijing, Tianjin, a total of 11 million mu of early rice cultivation. According to the local nature
