| Abstract: |
| Based on analysis of bio-temperature characteristics and eco-climatic condition of big cherry in Tianshui, Gansu Province, the correlational relationship between meteorological factors and big cherry climate yield were calculated using the statistical method.The result indicates that the average lowest temperature during the first 10 days to the middle ten days in April, extremely lowest temperature in April and the annual precipitation are the most main meteorological factors which affect big cherry growth.According to influencing degree of low temperature freeze injury in spring and spring drought to big cherry climate yield, the effective coefficient is carried out, and the risk of big cherry plating in Tianshui is discussed and estimated.Suggestions for utilizing properly climatic resources and developing big cherry production are also set forward. |
