Greenhouse vegetable production plays a decisive role in Wuhan City’s Vegetable Basket Project.This paper analyzed the meteorological observation data obtained from 1951-2016 and micro-climate observation data of winter vegetable greenhouse from 2014-2015.The results indicated that the mean temperature in January was about 3.5 ℃,and proportions of cloudy days and sunny days in winter were 46% and 40%,respectively.These climate conditions were not favorable for temperature rising inside of greenhouse.But under the environment conditions of greenhouse in Wuhan,daytime temperatures in greenhouse in sunny day and cloudyday in January,were 11.4 ℃ and 4.9 ℃ higher than that of outside greenhouse,respectively.These conditions could satisfy the growth of semi-cold tolerant vegetable varieties.In Wuhan cold air activities were frequent in early spring.During 50% years from 1951-2016 owing to fewer sunny days and more cloudy days,it was already late March or even late when the temperature was stably over 10 ℃.So it was very difficult to rise the temperature inside of the greenhouse.And it was also difficult to meet the requirement of warm-season vegetables for warm temperature.But in autumn,the sky was clear and air was crisp.And over 75% of the years from 1951-2016,owing to more sunny days and less cloudy days,winter set in basically later than November 16th.This condition was favorable for temperature rising in greenhouse and suitable for developing late autumn vegetable production.So we suggest that it is necessary to adjust the greenhouse vegetable production by reducing the ratio of warmseason vegetables proportion in spring and increasing the plantation of late autumn solanaceous vegetables.
