Abstract: According to the same basin of Taiyuan,it compared the situation in greenhouse production and development in Taigu county and Jiexiu city in 2008.It found that the the development of greenhouse of Jiexiu city which more economically was obviously lagging behind Taigu.This article analyzed the reasons for the slow development of greenhouse in Jiexiu city through many ways.Based on the sunshine data of Jiexiu and Taigu from 2001 to 2008,it analyzed spatial and temporal distribution and inter-annual changes for sunshine hours in Jiexiu city and Taigu county by using statistical tables and charts.It showed that relatively few hours of sunshine in Jiexiu city was an important negative factor for the slow development of greenhouse production.With the principal contradiction that reduced the number of sunshine hours,it proposed energy-saving emission reduction,transferred the production bases,improved the canopy lighting,made up for lack of sunlight to actively promote the scale of the development of greenhouse in Jiexiu.It had a certain reference value to arrange rational distribution of greenhouse production base of Jiexiu city,and improve production efficiency.

Key words: Jiexiu city, Greenhouse production, Sunshine hours
