日光温室冬季低温冻害致灾指标研究

Research on Disaster-Inducing Index of Minimum Temperature and Frost Weather for Sunlight Greenhouses in Winter

利用西宁市大通县设施农业气象服务示范站温室内外2012年12月1日至2013年2月28日气象观测数据,对温室内最低气温与气象因素进行多元回归分析,建立不同天气条件下温室内最低气温预报模型,结合低温冻害灾情,得出日光温室低温冻害致灾指标。

In this paper, by using a greenhouse inside and outside meteorological data from 1th December 2012 to 28th February 2013 provided by Datong meteorological service demonstration station of facilities ag-riculture,and by taking multiple regression analysis between the greenhouse minimum temperature and mete-orological factors data,established greenhouse minimum temperature forecast model under the different weath-er condition,combined with the disaster of minimum temperature and frost weather,conclusion that disaster-inducing index of minimum temperature and frost weather for sunlight greenhouses.
