安徽省江淮丘陵地区是一个中稻产区。这是因为中稻生长期短,能充分利用生长季节,有利于增加复种指数;同时中稻产量高而稳定。但这地区的中稻,大部分是麦茬中稻。常因小麦成熟較迟,收麦插秧劳畜力紧张,栽秧期遇到干旱,使部分中稻迟栽,影响产量的提高。 Jianghuai Hilly in Anhui Province is a middle-yielding area. This is because the short growing period of middle rice can make full use of the growing season, which is conducive to increasing the multiple cropping index. At the same time, the yield of middle-aged rice is high and stable. However, most of the medium-sized rice in this area is medium-sized rice stubble. Often due to the late maturity of wheat, wheat planting transplanting seedling tension, transplanting drought encountered, so that some late rice planted, affecting the increase of yield.
