Study on the heat potential of sequential cropping in solar greenhouse

The effect of increasing temperature and the heat potential of sequential cropping in,solar greenhouse were studied．The results show that the annual active accumulated temperature in．solar greenhouse is 2205．3℃ higher than that outside；four crops a year by interplanting cool-season crops with warm-season crops or by sequential planting cool-season crops，and three crops a year by sequential planting warm-season crops can be harvested in,solar greenhouse．The heat potential of the sequential cropping will be more higher if growing and transplanting seedlings are used in solar greenhouse．
