The Study Of The Solar Lean-to Without Wall's Greenhouse Main Meteorological Index And Performance

This article passes the solar lean-to greenhouse without wall and the ordinary sunlight greenhouse and the plastic greenhouse without wall each month of the illumination, the temperature and the humidity and so on, as well as in solar lean-to greenhouse without wall and the ordinary sunlight greenhouse cropping cucumber, tomato, rape and so on crops growth, yield and physiology observations, draws the following conclusion: 1 The solar lean-to greenhouse without wall illumination condition, especially behind greenhouse illumination, is higher than the ordinary greenhouse in the spring summer fall three seasons main productions season, is slightly higher than the plastic greenhouse without wall.2 The solar lean-to greenhouse without wall in the Huhhot winter coldest season, at night lowest temperature for - 1.2℃; compared to ordinary sunlight greenhouse low 1-2℃, but the midday temperature is actually higher than the ordinary sunlight greenhouse 2-6℃, may carry on the cold resistant edible vegetables production.3 In the solar lean-to greenhouse without wall the cucumber vegetative growth and the production surpasses the ordinary sunlight greenhouse, the cucumber ultimate output is higher than the ordinary sunlight greenhouse 26.8﹪. In the solar lean-to greenhouse without wall plants the cucumber leaf photosynthesis rate, the leaf chlorophyll content as well as vc content, the sugar content is higher than the ordinary sunlight greenhouse. 4 In the solar lean-to greenhouse without wall the tomato vegetative growth and the production surpasses the ordinary sunlight greenhouse, the tomato ultimate output is higher than the ordinary sunlight greenhouse 25.8﹪. In the solar lean-to greenhouse without wall plants the tomato leaf photosynthesis rate, the leaf chlorophyll content as well as vc content, the sugar acid ratio is higher than the ordinary sunlight greenhouse.5 In the solar lean-to greenhouse without wall the winter plants various rapes varieties the vegetative growth and the production and the ordinary sunlight greenhouse not obvious difference, the ultimate output slightly is higher than the ordinary sunlight greenhouse. In the two greenhouses the rape varieties are no apparent the seedling death phenomenon.All the analysis shows that the solar lean-to greenhouse in the main production season, illumination, the temperature, the humidity condition suits to the kind of Likes the high temperature vegetables growth, obtained the good quality and high output for the facility vegetables to provide the guarantee.
