影响川南浅丘区田坎玉米产量的气候条件分析

A Analysis of the Weather Conditions Affecting Balk Corn Yields in Hilly Area of South Sichuan

利用积分回归方法分析气候因子对川南浅丘区田坎玉米产量的影响。结果表明 ,日照、温度及降雨日数是影响田坎玉米产量的主要因子。苗期的高温 。

Affection of weather conditions upon balk corn yields in hilly area of Sichuan Provice was analysed by means of integral regression.The result indicated that sunshine hours,temperature and rain days were the chief factors affecting the corn yields.The high temperature during seedling period,the deficiency of sunshine during mid-priod of maize growth and excess rain days during filling and mature period are not beneficical to the corn yield.
