Abstract:
Aimed to low temperature condition of winter that suffered from solar greenhouse in Zhangye on cherry tomato production.From two aspects of the structure of solar greenhouse and the selection of low temperature resistant varieties,the change rule of temperature in solar greenhouses with different structures and the effect on cherry tomatoes growth in the low temperature period were studied.The results showed that the No.2 solar greenhouse had the better insulation performance than the No.1,average temperature in the low temperature period of the No.2 solar greenhouse was higher than the No.1 at 2.6℃,the cherry tomato daily average growth of plant height,transverse diameter and vertical diameter of three varieties in the No.2 were higher than the No.1.The daily average growth of transverse diameter and vertical diameter of cherry tomato variety ‘75-126’ in the No.1 decreased most obviously of three varieties.
