Abstract:

For this present situation which the low ground temperature constraint for winter cultivation of fruit vegetables,taking three varieties of pepper as test material,the effect of different root zone temperature on growth both aboveground and underground,photosynthetic parameters of pepper seedlings in solar greenhouse were studied,in order to provide a theoretical basis for the pepper cultivation in the winter solar greenhouse and preferably improvement of the soil temperature condition.The results showed that the plant height,aboveground part dry weight,underground part dry weight,dry weight of complete stool,leaf growth,leaf SPAD,photosynthetic rate,transpiration rate and inter-cellular CO₂ concentration in the optimal temperature were higher than the suboptimal and low temperature.The ratio of root to shoot was lower than the suboptimal and low temperature.
