【摘要】 为研究设施栽培大樱桃的较小需冷量以及最合适的扣棚时间,进行设施栽培大樱桃需冷量监测试验。试验选取鲁中山区的3个大樱桃温室,进行从秋季开始直至大樱桃采收结束期间温度等气象要素观测。同时结合温室外部天气变化对3个温室大棚的扣棚时间进行分析。结果表明:在需冷量的监测中,7.2模型的最小需冷量为1070 h,0~7.2模型的需冷量为484 h;当外界温度下降到-19.1℃时,花芽冻坏率为30%,应选择在较强冷空气来临之前扣棚。更多还原

【Abstract】 In order to study the less chilling requirements and optimal covering time of cherry in the sunlighthouse, a test of monitoring chilling requirements of cherry in the sunlight greenhouse was used. 3 sunlightgreenhouses in the mountainous area of middle region of Shandong Province were selected. The meteorologicalelements such as temperature were observed from autumn to the end of cherry harvest. And combined theweather change outsides the greenhouse, the covering time of cherry in 3 different greenhouses were analyzed.The results showed that, in the monitoring of chilling requirements, the least chilling requirement of 7.2 modelswas 1070 hours, and the chilling requirement of 0-7.2 models was 484 hours. When the outside temperaturedrops to-19.1℃, 30% of flower buds were frozen. The covering time of cherry should be selected before thestrong cold air coming.更多还原
