水稻旱种是北方水资源不足地区生产稻米的一条新途径,是实现机械化、节水、省工,降低生产成本,提高经济效益的一项种稻新技术。近年来,在天津种植面积逐年增加,已充分显示出广阔的发展前景。一、天津水稻旱种的发展简史解放初期,为减轻传统种稻劳动强度,谋求在水稻机械化方面有所突破,军粮城稻作试验站和国营芦台农场进行了机械旱直播试验。试验证明,旱直播可以实现水稻机械化,但死苗问题未能解决。1956年军粮城稻作试验站,从解决水稻机械化和插秧用水紧张出发,着手进行春稻苗期旱长(即现在的 Dry cultivation of rice is a new way to produce rice in areas with insufficient water resources in northern China. It is a new rice cultivation technology that realizes mechanization, water saving and labor saving, reduces production costs and increases economic benefits. In recent years, the area planted in Tianjin has been increasing year by year, which has fully shown a promising prospect for development. First, a brief history of the development of dry cultivation of rice in Tianjin In the early liberation, in order to alleviate the labor intensity of traditional species of rice, seek to achieve a breakthrough in the mechanization of rice, military grain city rice test station and the state-owned Lutai farm mechanical dry broadcast. Experiments show that dry planting can achieve rice mechanization, but dead seedlings problem can not be solved. 1956 Junliangcheng rice test station, starting from the solution to rice mechanization and water transplanting tension, proceed with spring drought rice seedling (that is, now
