摘　　要：本试验通过使用智能型温湿度记录仪，以露地为对照，对夏季高温季节3种防虫网覆盖方式下（大棚覆盖、小拱棚覆盖、苗床覆盖）的空气温湿度以及土壤或基质温度进行连续记录，初步摸索出3种防虫网覆盖方式下温湿度的变化规律。结果表明，高温晴天、阴雨天以及雨天后晴天的白天，不同处理纱网内的空气温度都低于露地；14：00时，3种天气情况下的空气湿度都高于露地，而土温都低于露地。大棚纱网及苗床纱网由于通风条件好，在晴好天气空气温度比小棚纱网低2℃左右。苗床纱网基质温度整个高温生长季节较其它3种栽培方式的土壤温度低2-3℃，可有效的防止烂菜，全封闭的生长和管理模式也起到很好的防虫效果，因此苗床纱网基质栽培可以作为夏季高温季节较好的叶菜类栽培方式。Air temperature humidity and medium temperature variation in three covering methods with fly net in hot season were continuously recorded by intelligent recorders of temperature and humidity. Based on the recorded data, the variation regularity was preliminarily found out. The results showed that the air temperature of different treatments was lower than that of open field on the hot day and rainny day and sunny day after rain in hot reason; At 14：00, the air humidity of different treatments was higher than that of Open field and the soil temperature was lower. The temperatur of the big arch shed and the seedling bed with fly net was lower about 2 ℃ than that of the little arch shed with fly net. The medium temperature of the seedling bed was lower 2-3℃ than other three cultivation methods, which can effectively prevent appearing rot vegetable. Fully-closed growing and management can prevent occuring insect pest, so the seedling bed with fly net may be the better cultivation method for leaf vegetables in hot season.
