摘要
为了探究大连市金州区影响大樱桃生长生产的气象条件,采用大连市金州本站的1961—2013年逐日气象资料,采用统计分析对大樱桃在金州区生长的气候条件进行评估,并对大樱桃各生长期的气象要素进行分析,其中采用Z指数作为各生长期的旱涝标准。结果表明:金州区充足的日照、适宜的雨水以及稳定的温度条件基本能够满足大樱桃生长发育,但是在部分生长期,存在影响大樱桃生长的气象因素,休眠期气温偏低对大樱桃越冬不利;近年萌芽期气温偏低、日照偏少是导致大樱桃减产的主要原因之一;花期的大风天气影响授粉;果期湿度偏大容易造成果裂。夏季突发的强降水以及秋季的降水偏少给大樱桃带来一定的影响。
In order to explore the meteorological condition affecting the cherry production in Jinzhou District in Dalian City,meteorological conditions for the growth of cherry in Jinzhou District were evaluated,and meteorological elements in each period during cherry growing were analyzed based on the daily data of Jinzhou District from 1961 to 2013,and Z index was used to judge the drought and flood.Results showed that ample sunshine,suitable rainwater and stable temperature conditions could basically meet the requires of high growth and development of cherry,but in part of the growth period,there were meteorological factors affecting the growth of cherry,temperature was relatively lower for overwintering of cherry.Low temperature and less sunshine were main reasons caused reduction of cherry.Windy weather affected flowering pollination.In fruit stage,relatively higher humidity could lead to fruit cracking.Sudden strong precipitation in summer and less precipitation in autumn could bring certain influence to cherry.
