河北省唐山市大棚葡萄催芽期气象要素调控效果分析

Analysis on the Regulation and Control Effect of Meteorological Elements during the Germination Period of Greenhouse Grapes in Tangshan City, Hebei Province

摘要: 本文针对玫瑰香葡萄品种，利用唐山市3个气象站2018~2019年的催芽期气象资料，包括逐时正点气温、相对湿度，大棚内0.5 m和1.5 m逐时气温，大棚内0.5 m和1.5 m逐时湿度，采用数理统计的方法进行分析，研究河北唐山大棚葡萄催芽期气象要素调控效果，结果表明：1) 大棚在催芽期的调控作用主要为增温、增湿和保湿，大棚能调控的最大增温幅度为22.1℃/小时，最大增湿幅度为76%/小时。且最高能增温到27.6℃，最高能增湿到99%；2) 无论在休眠期还是催芽期的哪个阶段，棚内温度变化始终为从高层到低层呈现逐渐升高的趋势，并且在大棚内从棚顶至地面平均每降0.5 m温度上升0.8℃~1.1℃，然而棚内各层的湿度几乎保持一致没有太大的变化。

Abstract: This article is aimed at muscat grape varieties, using the meteorological data of the germination pe-riod from three weather stations in Tangshan City from 2018 to 2019, including the hourly punctual temperature and relative humidity, hourly temperature at 0.5 m and 1.5 m in the greenhouse, hourly humidity at 0.5 m and 1.5 m in the greenhouse, using mathematical statistics to analyze the effect of meteorological factors during the germination period in Tangshan, Hebei Province, and the results show that: 1) The regulation effect of the greenhouse in the germination period is mainly to increase temperature, humidify and moisturize. The adjusted maximum temperature increase rate is 22.1˚C /hour, and the maximum humidity increase rate is 76%/hour. And the highest temperature can be increased to 27.6˚C, and the highest can be humidified to 99%. 2) No matter which stage of the dormant period or the germination period, the temperature change in the shed always shows a gradual increase trend from high to low, and in the greenhouse. The temperature rises by 0.8˚C - 1.1˚C for every 0.5 m drop from the roof to the ground, but the humidity of each layer in the shed remains almost the same without much change.
