摘要
温室内湿度环境的调控是农业保护地生产中的重要环节,关系到植物的生长状况、灌溉措施的调节以及多种病害的生态防治。现以北京地区具有代表性的砖砌空心墙钢拱架结构温室为例,以2006年12月至2007年6月间的日湿度值为分析数据,运用季节性时间序列分析法建立了当地温室内月平均的日湿度AR(p)模型,经过与实测值对比,预报效果较好,为合理调控温室内的湿度提供了理论依据和定量指标。
Control of humidity environment in greenhouse is a key link to agricultural production. Humidity control concerns to plant growth condition, irrigation regulation and ecological prevention and control of several plant diseases, In this paper, the daily humidity data collected from Dec. 2006 to Jun. 2007 in hollow-brick-wall-steel-truss-structure-greenhouse which is representative in Beijing was studied. Through applying the theory of season random time series, an AR （p） model to forecast the local greenhouse inner daily humidity was built up. Through comparison with the measured value, the model had good effect. It provided the theories gist and the quantity index for the technology of controlling the greenhouse inner humidity.
