摘要
在分析天水市地区大樱桃物候特征及生态气候条件的基础上,运用统计学方法计算分析该区域气象因子与大樱桃产量的关系。结果表明,4月上、中旬平均最低气温、4月极端最低气温及年降水量为影响当地大樱桃生长的主要气象因子,根据春季低温冻害及春旱对大樱桃产量的影响程度,确立了影响系数,对大樱桃种植的风险程度进行评估。并提出了合理利用气候资源,发展大樱桃产业生产建议。
Baaed 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.
