水稻是辽宁省的主要细粮作物,虽不断增产,但仍供不应求。然而由于水源不足,使水稻生产的发展受到影响。种植陆稻固然可以增产细粮,但陆稻在抗倒伏性、耐肥性和高产潜力及品质等方面远远不及水稻。因此在水源不足的情况下,能否在旱田条件下栽培水稻,长期以来就成为人们颇为关心的问题。但由于过去对水稻旱种问题讨论和研究较少,对水稻旱种能否行得通,技术上存在什么要解决的问题等都不够清楚。为了促进对水稻旱种的了解和为今后的研究工作提供线索,本文根据 Rice is the main staple crop in Liaoning Province. Although it continues to increase production, it still falls short of demand. However, due to insufficient water resources, the development of rice production is affected. Planting inland rice can certainly increase grain yield, but the upland rice is far less than rice in terms of lodging resistance, fertility resistance, high yield potential and quality. Therefore, under the condition of insufficient water resources, whether or not rice is cultivated under dry land conditions has long been a problem that people are most concerned about. However, due to the lack of discussions and researches on dry cultivation of rice in the past, it is not clear enough about whether dry cultivation of rice is feasible and what problems need to be solved technically. In order to promote the understanding of dry cultivation of rice and provide clues for future research work,
