【Abstract】 Huaihe valley, spreads between warm temperate zone and north subtropical zone, is an important producing field of grain and cotton of China and it pertains to humid monsoon region, where the distinction of seasons is evident. In Huaihe valley the quantities of the light, heating, water resource are harmonious relatively. The yearly distribution of water and heat synchronizes with the growth of crops, thus it is one of the most appropriate place to develop dry paddy with preferable harmony. Dry paddy is a method that adopts a variety of wheat that can forbear dry environment, which is directly sowed on the dry land after wheat harvest without retaining water layer during growth, thus making full use of natural precipitation. The future of the dry paddy in Huaihe valley is discussed in this paper.
