Sugarcane's Growth and Meteorological Conditions in the Valley of Jinshajiang River

The analysis of factor screening is done by the correlation between the increment progressively of ten-days growth height of sugarcane and meteorological factors. In the dry-hot river valley of Jinshajiang with very great daily range of temperature, the influence of surface minimum temperature on the growth speed of sugarcane is maximum. During rush growth period in summer, its growth speed has also close correlation with previous three pentad's rainfall amount, but its correlation with sunshine is minimum. Therefore, when making agricultural comprehensive exploitation of dry-hot river valley of Hengduan mountain area in Southwest China, we not only consider the sunshine condition and pay attention to the improvement of agricultural irrigation condition but also pay great attention to the influences of some climatic features such as temperature condition on agricultural production.
