北京种植桃气候适应性及优势分析

依据桃的光、温、水及病害发生等生长气候特性,选择了北京平谷地区典型的早、中、晚熟等4个品种桃,利用北京平谷地区30年的气候资料,从地形、土壤和水资源、冬季冻害和霜冻、开花授粉、果实生长期、日较差与病害等多方面分析论证了平谷桃种植的气候适应性及相对于北京南部平原地区的气候优势。分析表明,平谷桃种植在气候资源上具有地形小气候优势,且冬季无冻害之忧,春季几乎无低温霜冻之害,开花授粉期相对平原地区具有气候优势,果实生长期适宜日数较多,而不适宜的高温日数较大兴区偏少,在对果实品质有影响的日较差方面相对于平原地区具有明显优势,病害发生发展也较大兴区轻。与北京其他地区相比,平谷气候更适于发展桃种植。
