| 摘 要： | 研究咸阳石榴种植的气候适宜性,充分利用气候资源,找出咸阳石榴种植的适宜区域。利用咸阳12个国家气候观测站1988—2017年最新气象观测资料,采用GIS技术对咸阳石榴栽培进行气候适宜性精细化区划,以期为咸阳石榴生产及农业结构调整提供科学依据。通过分析影响生长和产量的主要气候因子,筛选出咸阳石榴从现蕾至果实成熟需≥10℃的有效积温、年生长期内需≥10℃的有效积温、年日照时数、9月日照时数、7—9月降水量、日平均气温18~21℃时的日较差、年极端最低气温和旬极端最低气温等8个气候适宜性精细化区划指标。评估发现石榴种植优质区占咸阳市面积的14.9%,主要分布在三原、泾阳大部、渭城区西北部、礼泉东部、乾县北部;适宜区占21.3%,分布在兴平市、秦都区、渭城区、礼泉县南部、乾县南部及武功北部台塬区;劣质区占16.6%;不适区占47.2%。咸阳旱腰带以南除武功外都是石榴种植适宜区,该区域光、热、水气候资源满足石榴优质生产所需的全部气象因子,可以大力发展石榴栽培。

| Abstract: | To study the climate suitability of pomegranate planting, make full use of climate resources, and find suitable areas for pomegranate cultivation in Xianyang, based on the latest meteorological observed data of 12 stations in Xianyang from 1988 to 2017, GIS technology was used to carry out climatic suitability regionalization of Xianyang pomegranate cultivation, aiming to provide a basis for pomegranate production and agricultural structure adjustment. There were 8 indices of climatic division for pomegranate, namely, ≥10℃ active accumulate temperature from bud emergence to fruit maturity, ≥10℃ active accumulate temperature during the annual growth period, sunshine hours of the year, sunshine hours on September, precipitation from July to September, the average temperature difference between day and night at 18-21℃, extreme minimum temperature of the year, extreme minimum temperature of ten days. The results showed that: the quality area of pomegranate cultivation accounted for 14.9%, mainly distributed in Sanyuan, most of Jingyang, northwest of Weicheng District, eastern Liquan, and northern Qianxian; the suitable area accounted for 21.3%, distributed in Xingping City, Qindu District, Weicheng District, the southern part of Liquan County, the southern part of Qianxian County and the Taiyuan District of Wugong north; the inferior area accounted for 16.6%, and the unsuitable area accounted for 47.2%. Except Wugong, the south of Xianyang dry belt is a suitable area for pomegranate planting, the light, heat and water climate resources in this area meet all the meteorological factors needed for high-quality production of pomegranate, and the cultivation of pomegranate can be developed in this region vigorously. |
