Abstract:

Northern part of Anhui is one of major wheat producing areas in China. The total amount of rainfall is sufficient for wheat season; however, it is unevenly distributed at the different growth stages, resulting in risk of yield losses. In order to optimise the cultivation in North Anhui, it is essential to characterise the rainfall pattern for wheat growth particularly in the critical period (i.e. the months of sowing and harvesting). By analysing the rainfall data from 1955 to 2017, this study characterised the rainfall pattern from six sites representing different regions of North Anhui. The frequency of continuous rainfall days during sowing and harvesting periods were quantified based on 63 years rainfall distribution. The characterisation of rainfall in six representative sites in North Anhui were able to be used to guide wheat sowing and harvesting, which could help farmers to make decisions and avoid likelihood of cropping risks.
