摘要：

利用河套灌区18年向日葵观测资料和相应气象资料，计算了向日葵各发育期气温、日照等要素，分析了各发育期适宜农业气象条件，并利用气候资料与气象产量建立了回归模型，通过地理信息系统将河套灌区向日葵种植进行了适宜分区。

Abstract:

Make use of the river set infuses two observation post of area for 18 years, the sunflower prognosticates data and corresponds the weather data, computing each growth of wheat period air temperature,sunshine etc. main factor, analyze each growth period feat with disadvantageous condition, and made use of the weather data and the weather yield to build up back to return model, infuse the river set through the geography information system the area wheat planted to carry on a feat cent area.
