由于早稻品种米质欠优、商品率不高、价格低，种早稻的比较效益低，加之有些地方连年种植双季稻导致土壤理化性状不良。于是有人提出用水旱轮作的方法改良土壤，推出了玉米一晚稻的种植模式以替代双季稻。我们农业部门也曾经采取过一系列栽培措施试种水田玉米，但都未取得进展 Due to the poor quality of early rice varieties, commodity rate is not high, low prices, the comparative efficiency of early rice is low, combined with some areas planted double cropping rice in successive years led to poor soil physical and chemical properties. So some people proposed to use water and drought rotation method to improve the soil, launched a corn planting mode of a late rice to replace double cropping rice. We have also adopted a series of cultivation measures in the agricultural sector to test paddy field corn, but no progress has been made
