南方避雨栽培内温湿度环境分析

摘要:
采用ZigWSN物联网信息服务平台设备采集温湿度等环境数据,分析避雨大棚内外的温湿度环境以及典型天气下的变化特征。结果表明,避雨栽培模式下的棚内日温差平均可达21.1℃,平均温度比露地提高6.4~9.4%。典型天气下,晴天的棚内外温度变化呈“V”型,而晴天的棚内外湿度呈“倒V”型。棚内温度极值比棚外提前2小时达到峰值,这对农业生产具有指导作用。

Abstract:
This paper analyzed the temperature and humidity of the rain-shelter and the environmental change characteristics under typical weather using the ZigWSN internet of things information service platform equipment. The results showed that the average daily temperature difference in the rain-shelter cultivation could reach 21.1℃, and the average temperature was 6.4~9.4% higher than that in the open field. In typical weather, the change of temperature inside and outside the rain-shelter in the clear days was "V"-shaped, while the humidity in the clear days was "inverted V"-shaped. The temperature extreme inside the rain-shelter reached its peak value 2 hours earlier than outside the rain-shelter, which had a guiding function on agricultural production.
