旱稻 ,也称陆稻 ,是一种能够在近似旱地生态条件下生长发育的特殊稻类。它适宜于低洼易涝旱地、雨水较多的山地及水源不足或能源紧缺的稻区种植。近年来 ,黄淮流域旱稻种植面积迅速扩大。但由于过去对旱稻品种改良和栽培技术研究不够 ,旱稻的单产较低 ,影响了农民收益。为此 , Upland rice, also known as Upland rice, is a kind of special rice that grows and develops under the similar ecological conditions of dry land. It is suitable for low-lying flood-prone drylands, more rain-prone mountainous areas and underdeveloped or energy-scarce rice areas. In recent years, the planted area of ​​Upland rice in the Huanghuai Basin has rapidly expanded. However, due to the lack of research on the improvement and cultivation techniques of upland rice in the past, the yield per unit area of ​​upland rice was low, which affected the income of farmers. to this end ,
