景德镇市引种沾化冬枣的气候条件分析

为了配合景德镇市政府做好冬枣引种工作,解决冬枣引种过程中出现的气象问题,明确景德镇市气象条件的利弊,达到趋利避害的目的,实现农业增产、农民增收的目标,作者根据气候资料的统计原理,对景德镇市与沾化县1981～2010年30 a的气候资料进行了统计分析。结果表明：景德镇市可以种植冬枣。但从气候条件来看,景德镇市较沾化县具有降水多、气温高、日照少的特点;根据景德镇试种冬枣的生长发育情况,对景德镇与沾化冬枣生长发育期间的气候条件进行了对比分析,认为景德镇市冬枣生长发育期间的气象条件不如沾化县,主要表现在4～6月多暴雨、少日照,7～9月高温和干旱,景德镇冬枣病虫害较沾化严重。因此,景德镇市在引种冬枣过程中,要注意选择排灌方便、背风向阳的地段建园,并注意做好干旱预防和病虫害防治工作。
