【摘要】：基于红枣果园冬季实测温度,对比分析果园内、外温度变化差异及其与气象站气温关系,采用线性回归方法根据气象站气温资料建立果园实际温度预测模型。结果表明,冬季红枣果园内、外平均气温差异不显著,但日变化趋势基本一致;最低气温变化存在显著差异(P0.05),果园内平均最低气温比果园外偏高1.2℃,极端低温偏高1.7℃。冬季气象站平均气温显著高于果园内外气温变化(P0.01),分别偏高1.2、1.3℃。气象站最低气温的差异变化幅度大于平均气温的差异,日最低气温比果园内、外偏高1.5℃、2.7℃,冬季极端低温偏高1.4℃、2.7℃。果园小气候的形成显著影响极端低温的差异变化,冬季气温比气象站温度偏低,利用气象站气温变化预测果园内外实际气温差异比较可行,关系模型检验绝对误差在0.3~0.8℃之间,可为红枣果园开展冬季冻害监测预警服务提供借鉴参考。
[Abstract]:Based on the measured temperature of jujube orchard in winter, the variation of temperature in and out of the orchard and its relationship with the temperature of meteorological station were compared and analyzed. Based on the temperature data of meteorological station, the prediction model of actual temperature of orchard was established by linear regression method. The results showed that there was no significant difference in the average air temperature in winter jujube orchard, but the diurnal variation trend was basically the same, and the lowest temperature was significantly different (P0.05). The mean minimum temperature in the orchard was 1.2 鈩，
