摘要:

为探究宁夏中部干旱带不同跨度拱棚温湿度、光照强度变化规律,研究选取当地跨度8、10、16、20 m的4座双层棚膜拱棚,利用紫藤连线设备检测相关环境参数。结果表明,温室环境受外界天气影响较大,同样天气条件下4座温室环境参数变化趋势相同,但存在一定差异。在温度方面,随着跨度增加,拱棚内1月平均气温16 m跨度最高,8、12 m次之,10 m最低;在晴天、雪天和阴天3种典型天气里,10 m跨度的全天气温能维持在一个较高的水平。在湿度方面,4种跨度的拱棚均能保持较为适宜的空气湿度(相对湿度40%~70%)。在光照强度方面,4座拱棚内的光照强度均较低,均在晴天、雪天和阴天3种典型天气里呈现出单峰曲线。综合考虑,跨度10 m的拱棚能够在冬季维持较好的温湿度和透光性,适宜在当地推广。

Abstract:

To explore the variation law of temperature, humidity and light intensity of different span arch sheds in the arid belt of central Ningxia, we selected four local double membrane arch sheds spanning 8, 10, 16 and 20 meters, and used zigvine wiring equipment to detect relevant environmental parameters. The results showed that the greenhouse environment was greatly affected by the external weather, and the variation trend of environmental parameters in these four arch sheds was almost the same except some differences. In terms of temperature, with the increase of the span, the average temperature of 16-meter-span in January was the highest, followed by that of the 8-meter-span and 12-meter-span, and that of the 10-meter-span was the lowest. In the three typical weathers of sunny, snowy and cloudy days, the all-day temperature of the 10-meter-span could be maintained at a high level. In terms of humidity, the four spans could maintain relatively appropriate air humidity (relative humidity 40%-70%). The light intensity is low in the four arch sheds and showed a single peak curve in sunny, snowy and cloudy days. Generally speaking, the 10-meter-span shed can maintain good temperature, humidity and light transmittance in winter, and is more suitable for local promotion.
