近30年山东省日光温室番茄低温冷害发生规律研究

摘要

Based on the auto -meteorological observation data from October,1984 to April,2014 in Shandong Province and the greenhouse auto -micro -climate observation data from 2007 to 2014,the outside grade indexes of chilling injury to greenhouse tomato were obtained using the inside grade indexes and the method of 80% guarantee rate in meteorology.Using the outside grade indexes of chilling injury to greenhouse tomato,the temporal and spatial statistic analysis was conducted to study the occurrence rules of the chilling injury in Shandong Province in recent 30 years.The results showed that the chilling injury of greenhouse toma-to mainly happened in winter in Shandong Province.The grade light was the most common,and mainly happed in December.The grade medium and heavy mainly occurred in January.The regions of chilling injury appeared mainly in the northwest Shandong,the east of middle Shandong,and part of the inland of Shandong peninsula.%基于1984年10月－2014年4月山东省自动气象观测站资料及2007－2014年日光温室小气候自动观测站资料，结合日光温室内番茄低温冷害农业气象等级指标，利用80％保证率方法，统计分析得到了日光温室外番茄低温冷害农业气象等级指标；应用该指标，对近30年山东省日光温室番茄生长季内低温冷害发生规律进行时间及空间的统计分析，结果表明山东省日光温室番茄生长季内低温冷害主要出现在冬季，年平均轻度低温冷害发生天数最多，主要出现在12月；1月是中度和重度低温冷害的高发期；鲁西北、鲁中东部及半岛内陆部分地区是发生低温冷害的主要区域。
