| Abstract: | 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. |
