台湾青枣在福建主产区的气候适宜度

Climate suitability of Ziziphus mauritiana in the main planting areas of Fujian Province,China

台湾青枣属新兴果树品种,经济效益显著。为实现台湾青枣在福建的优质高产,本研究基于产量和气象数据,结合文献和物候观测资料以及农业气候适宜度模型,给出了台湾青枣在福建主产区的气候适宜度模型参数,分析了主产区气候适宜度特征及其变化趋势。结果表明:基于等权重求和法构建的模型可靠性最高;台湾青枣在福建主产区的气候适宜度较高,多数年份为适宜或较适宜;1996-2013年,气候条件对台湾青枣生长的影响总体呈趋好态势,有利于发展青枣生产;主产区全生育期温度适宜度>综合气候适宜度>日照适宜度>降水适宜度,9-10月是水分管理的关键期。研究结果对福建省台湾青枣的生产管理和长期规划具有指导意义。

Taiwan green jujube(Ziziphus mauritiana)is a new fruit variety,with remarkable economic benefit.To achieve high quality and high yield of jujube in Fujian Province,we quantified the climate suitability model parameters of the jujube in main production areas of Fujian,and analyzed climate suitability characteristics and change trend of main production areas,based on the yield and meteorological data,combined with literature and phenological observation data and agricultural climate suitability model.The results showed that the model based on the equal weight summation method had the highest reliability.The climate suitability of jujube in main production areas of Fujian was higher,with most years being suitable or much suitable.From 1996 to 2013,the influence of climate conditions on jujube growth was generally in a good trend,which was conducive to the development of jujube production.The suitability of the main production areas in the whole growing season was ranked as temperature suitability>comprehensive climate suitability>sunshine suitability>precipitation suitability.September and October are the key period of water management.Our results are important in guiding production management and long-term planning of Taiwan green jujube in Fujian Province.
