70年代初大面积“旱改水”以来,淮北稻区稻田面积相对稳定,单产不断提高,目前已成为江苏的高产稻区。以大面积“旱改水”前的1970年为例,全省水稻面积为3558.13万亩,徐淮的水稻面积仅507.28万亩,只占全省稻田面积的14.24％。1972、1976年,是江苏历史上水稻面积最多的年份,分别为4703.29、4666.34万亩,徐淮的水稻面积分别为938.58、943.15万亩,占全省面积的19.96％、20.2％。进入80年代,江苏省稻田面积逐渐缩小,主要是在苏南。在淮北三市中,徐、连
Since the large-scale drought-relief water in the early 1970s, the area of paddy fields in the paddy areas of Huaibei has been relatively stable with the continuous improvement of yields, and has now become a high-yielding rice area in Jiangsu. For example, in 1970, before the drought was changed to a large area, the province’s rice area was 35,581.3 hectares. Xuhuai’s paddy area was only 5,072,800 hectares, accounting for only 14.24% of the total paddy field area in the province. In 1972 and 1976, it was the largest rice area in the history of Jiangsu Province, with a total area of 4703.2966663 million mu. Xuhuai’s rice area was 938.5894315 million mu, accounting for 19.96% and 20.2% of the province’s total area respectively. Into the 1980s, Jiangsu Province, the area of paddy fields gradually reduced, mainly in southern Jiangsu. In the three cities in Huaibei, Xu, even
