大棚樱桃品质与小气候因子的相关分析

Correlation analysis of cherry quality and microclimate factors in greenhouse

为研究山东省烟台市大棚内小气候因子的变化规律及其对果实品质的影响,于2016年1—5月在烟台市芝罘区开展了大棚甜樱桃(Prunus avium L.)观测试验,对3个试验棚和1个对照棚内气候及相应外界气象条件进行了观测记录和对比分析。结果表明,烟台市大棚甜樱桃生产的最佳棚内气候是花期白天温度为12～22℃,夜晚温度为6～8℃;果实膨大期白天温度为13～23℃,夜晚温度为8～10℃;着色至采收期,白天温度为16～25℃,夜晚温度为10～12℃;大棚湿度白天控制在50%,夜晚低于80%,光照度为15000 lx。

In order to study the variation of microclimatic factors in greenhouses and the effects on cherry(Prunus avium L.)fruit quality in Yantai city, Shandong province, the observation experiment of cherry in greenhouse was carried out in Zhifu district, Yantai city from January to May in 2016. Through the observational records and comparative analysis of three experimental greenhouses and one control greenhouse and their external meteorological conditions, the optimum greenhouse climate for cherry production in Yantai area was concluded that 12~22 ℃ in daytime and 6~8 ℃ in night at flowering stage,13~23 ℃ in daytime and 8~10 ℃ in night at fruit expansion stage, 16~25 ℃ in daytime and 10~12 ℃ in night from coloring to harvesting stage, humidity of 50% during daytime, less than 80% at night, and luminance of 15000 lx.
