水稻旱种是一项省水栽培法,其主要特点可概括为:“足墒旱种,苗期旱长,出苗后灌水”。这项技术我省在五十年代初曾经有过试验示范。但由于当时生产条件的限制,局限于缺水地区采用。我省近年江河水位下降,水的流量不足;由于十春九早的特点春播期间尤为严重。但水稻的种植面积却一直在不断扩大,水稻需水与水量不足的矛盾越来越大。据此,我所在总结先行试验的基础上,自1979年开展水稻旱种技术的试验研究,现
Dry cultivation of rice is a water-saving cultivation method, its main features can be summarized as: “enough moisture soil drought, seedling drought, emergence after irrigation.” This technology in our province in the early fifties there have been demonstration. However, due to the restriction of production conditions at the time, it was limited to water-scarce areas. In recent years, the water level of rivers in our province has been declining, and the flow of water has not been enough. Since the characteristics of the ten spring and early nine seasons are particularly serious during spring seeding. However, the planting area of rice has been constantly expanding, and the contradiction between water demand and water shortage has been increasing. Based on this, based on the conclusion of the first trial conducted by me, the experimental study on the technology of dry cultivation of rice started in 1979,
