系统观测了桃树设施栽培中的四种日光温室内 1～ 3月份正常天气及阴雪天气条件下温湿度变化情况。结果表明 ,温室内温湿度变化呈明显的规律性 ,且基本能满足桃树生长发育的要求 ,但以砖砌空心墙钢拱架结构的保温性能最佳 ,在鲁东南地区 1、2、3月份的平均温度分别为 1 4.2℃、1 6.5℃、1 6.7℃ ,在 1月份连续 8天的阴雪天气中 ,日均气温仍达 7.8℃。其次为砖砌空心墙竹木结构、砖砌 3 7依托式竹木结构、砖砌2 5依托式竹木结构。
The changes of temperature and humidity in normal sunlight from January to March in four sunlight greenhouse cultivated in peach trees and snowy and snowy weather conditions were systematically observed. The results showed that the change of temperature and humidity in the greenhouse was obviously regular, and could basically meet the requirements of peach growth and development. However, the thermal insulation performance of the brick arch hollow steel arch structure was the best, The average monthly temperatures were 1 4.2 ℃, 1 6.5 ℃ and 1 6.7 ℃. In the snow-covered weather of 8 consecutive days in January, the average daily temperature still reached 7.8 ℃. Followed by brick hollow wall bamboo structure, brick 3 7 relying on bamboo structure, brick 2 5 relying on bamboo structure.
