摘要
利用磴口县国家气象观测站1988-2017年气象观测资料和华莱士蜜瓜生育期监测数据,引入气候适宜度计算模型,分析温度、日照对华莱士蜜瓜生长发育的影响.结果表明,出苗期温度、日照时数适宜度分别为0.42、1,综合适宜度为0.65,适宜度一般;3叶期分别为0.74、1综合适宜度为0.86,适宜度高;伸蔓期-成熟期温度、日照时数和综合适宜度均在0.85以上,适宜度高.通过年际变化来看,温度、日照时数和气候适宜度均呈现上升趋势,倾向率分别为0.034/10 a、0.015/10 a和0.026/10 a,表明磴口县气候对华莱士蜜瓜生长整体适宜度高,且呈现继续上升趋势.华莱士蜜瓜含糖量和产量与气候适宜度成正相关,相关性通过0.01检验;磴口地区昼夜温差大也是含糖量高的重要因素之一.
The meteorological observation data from 1988 to 2017 of Dengkou Meterological Station and monitoring data of wallace melon during the whole growth period were used in this research, the effects of temperature and sunlight on the growth of wallace melon were studied by a climate suitability degree model. The results showed that, at the emergence stage, the suitability of temperature and sunshine duration were respectively 0.42 and 1, and the comprehensive suitability was 0.65, which was general. At the three leaves stage, the suitability of temperature and sunshine duration were respectively 0.74 and 1, the comprehensive suitability was 0.86, which was high. During the vine elongation and maturity period, the temperature, sunshine duration and comprehensive suitability were all above 0.85, and the suitability was high. In terms of interannual variations, the temperature, sunshine hours and climate suitability all showed an upward trend, and the tendency rates were 0.034, 0.015 and 0.026/10a, respectively. The results showed that the climate of Dengkou had a high overall suitability for the growth of wallace melon, and exhibited a continuing upward trend. The sugar content and yield of wallace melon were of positive correlation with climate suitability, and the correlation was tested by 0.01. The large temperature difference between day and night in Dengkou was also one of the important factors causing high sugar content.
