摘要:

为编制广西‘沃柑’果实品质等级种植气候适宜性区划图,为优化柑橘产业布局提供科学依据。本研究基于“3S”技术和柑橘果实品质形成关键期气候要素适宜度指标,评估广西优质‘沃柑’果实品质等级气候要素适宜度。结果表明:广西‘沃柑’花蕾至盛花期、生理落果期气候适宜度地域差异不明显,大部地区为最优或优质等级;果实膨大期至成熟采收期的气候要素适宜度则具有明显的地域性,其中果实着色期、成熟期的气候适宜度等级呈现随纬度增加而递减趋势,这与冬季气温随纬度递减而无法满足‘沃柑’果实着色、成熟所需热量条件相一致。广西特优‘沃柑’果实品质等级种植最适宜气候区主要分布在北回线临近及右江河谷、桂西南等地。

Abstract:

In this study, the climate suitability planting map of Orah’s fruit quality grade in Guangxi was compiled, aiming to provide a basis for optimizing the layout of citrus industry. Based on the “3S” technology and the climatic factor suitability index in the critical periods of citrus fruit quality formation, the climatic factor suitability of Guangxi high-quality Orah’s fruit was evaluated. There is no obvious regional difference in climate suitability from the flower bud to the full flowering period and the physiological fruit-falling period, and most areas are of the best or high-quality grade; the climate element suitability of the fruit expansion period to the mature harvest period has obvious regional characteristics. Among them, the climate suitability grade of fruit coloring stage and maturity stage showed a decreasing trend with increasing latitude, which is consistent with the winter temperature decreasing with latitude and unable to meet the caloric conditions required for the fruiting and ripening of Orah’s fruit. The most suitable climatic region for excellent Orah’s fruit quality grade in Guangxi is mainly distributed in the areas near north-link line, Youjiang River valley, southwestern Guangxi, and etc.
