摘要
呼伦贝尔地区位于内蒙古自治区东北部,地处高寒地区,日照充足,发展日光温室具有较强的资源优势。番茄是呼伦贝尔地区温室种植的主要作物,本文利用呼伦贝尔地区典型日光温室气象观测数据,分析2024年3-8月不同天气状况下番茄整个生育期温室内外气象要素变化特征,以此科学指导日光温室番茄生产,为农户进行高效的番茄栽培管理提供科学依据。结果表明:不同季节、不同天气状况下的温室内温湿度变化趋势基本相同。在晴天、多云和阴天3种天气条件下,晴天温湿度日变化最为明显,阴天温湿度日变化最为平缓,温室内日温差变化幅度为晴天>多云>阴天,相对湿度日变化幅度为晴天>阴天>多云。不同时刻温室内外温湿度变化趋势基本相同,温室内气温均高于温室外气温,白天温室内相对湿度较室外低,夜间温室内相对湿度较室外高。温室内外气温日平均变化趋势相同,相对湿度日平均变化差异明显。
The Hulun Buir region,located in the northeastern part of the Inner Mongolia Autonomous Region,is characterized by its high altitude and cold climate and abundant sunshine,presenting strong resource advantages for the development of solar greenhouses.Tomatoes are the primary crop cultivated in greenhouses in Hulun Buir.Using typical solar greenhouses in Hulun Buir,the variation characteristics of meteorological elements inside and outside the greenhouse during the entire growth period of tomatoes under different weather conditions from March to August 2024 were analyzed,which could provide scientific guidance for solar greenhouse tomato production and offer a scientific basis for farmers to implement efficient tomato cultivation and management.The results showed that the diurnal trends of temperature and humidity inside the greenhouse remained basically consistent in different seasons and weather conditions.Among the three weather conditions,the diurnal variations in temperature and humidity were most obvious on sunny days and most stable on overcast days.The diurnal variation of temperature difference in greenhouse followed the order:sunny>cloudy>overcast days,while the diurnal variation of relative humidity followed:sunny>overcast>cloudy days.The variation trends of temperature and humidity inside and outside the greenhouse were basically the same at different times,with the temperature inside the greenhouse higher than that outside the greenhouse.The relative humidity inside the greenhouse was lower during the day,whereas it was higher at night.The diurnal average temperature variation trends inside and outside the greenhouse were consistent,while significant differences were noted in the diurnal average relative humidity variations.
