Abstract:

In Guangdong,the major unfavourable factor for planting corn in winter is the climatic condition. The 1989-1992 statistical data about the climatic adaptability of the winter corn showed that the corn is sensative to low temperature during the period from differentiation of ear to tasseling while the sunshine hours from filling to mature period are very important to the output of the winter corn. In mis paper the accumulated temperature of ≥ 0℃ during winter,the average monthly minimun temperature of December,and the number of the days with weather of number of low temperature and rain in spring are chosen as the demarcation indexes for winter corn planting regionalization in Guangdong. Suitable,sub-suitable and unsuitable zones are delimitated with fuzzy mathematics method.

Key words: Winter-corn, Climatic adaptability, Planting regionalization
