摘要
根据适宜柠檬种植的生态环境条件,利用安岳县1971-2008年的气温和降水量等观测资料及柠檬种植资料,分析安岳柠檬生长的生态气候环境条件及其气候变化的影响。分析表明,安岳年平均温度17.4℃,≥10℃的年活动积温5950℃,极端低温-2.4℃,年降雨量990.0mm,年日照时数1185.3h,无严重霜冻,同时具有柠檬生长的土质温暖、疏松、厚实等土壤种植环境和栽植条件,适于栽植柠檬。由于柠檬种植和分布对气温和水分的敏感性,气温与降水的候月变化及年际变化等对柠檬生长各个阶段都有一定的影响,因此,进一步加强安岳气候环境及其变化影响的研究,对安岳柠檬生产的规划发展有重要的指导作用。
In accordance with the ecological environmental conditions suitable for lemon plant the temperature and precipitation data and lemon plant data in Anyue County between 1971 and 2008 are used to analyze the ecoclimatic environmental conditions and impacts of climate changes on the lemon growth. The analysis shows that the mean annual temperature is 17.4℃, the yearly accumulated temperatures more than 10℃ are 5950℃, the extreme low temperature is - 2.4℃, annual rainfall is 990.0mm, annual sunshine hours are 1185.3h and no severe frost in Anyue. Hence it is suitable for the lemon growth. Since the temperature and moisture sensitivity of the lemon cultivation and distribution the temperature and precipitation changes and inter-annual changes have a certain impact on the lemon growth in the various stages. Therefore the re, arch of the Anyue environment and its climate change impacts on the lemon production planning and development has an important meaning.
