合肥市地处江淮丘陵中纬度地带,位于江淮之间,全年气温冬寒夏热,春秋温和,属于暖温带向亞热带的过渡带气候类型。属亚热带湿润季风气候,年平均气温15.7℃,降雨量近1000mm,日照2100h左右。水系发育分别源于江淮分水岭两侧,或南流注长江,或北流入淮河。全市多年平均径流总量21亿m3,多年平均拦蓄量9.6亿m3。土地资源类型多样,耕地面积279万hm2,占土地总面积的38.3%;水面76万hm2,占10.5%;林地2.5万hm2,占3.4%;其他用地347.5万hm2,占47.8%。境内农业、水产资源丰富,适宜稻、麦、棉、油料、菜、瓜、果、麻等多种作物的种植。

再生稻作为一种栽培方式,非常适宜在合肥地区种植。再生稻即种1季收获2季,在头季水稻收割后,利用禾蔸重新发苗、抽穗结实再收一季的水稻。这一技术高产实惠,省工省力,且再生稻米品质优,具有较好的经济效益和生态效益。综合各个方面,笔者选用生育期适中的水稻品种泰两优1332在合肥地区进行了再生稻种植的高产栽培试验。……
