Abstract：In order to deal with the problems of low -temperature stress in winter and spring in north China solar greenhouses,the effects of width,slope,plastic film mulching,soil moisture content on improving the performance of heat storage and release were studied to optimize the structure parameters of soil ridge.The results showed that it was effective to increase the root zone temperature through optimizing the structure pa-rameters of soil ridges.Under the plastic film mulching conditions,the heat storage and release ability of soil ridges was higher with 17 cm of top width,37 cm of bottom width,63°of slope and 6% or 15% of soil water content,so the root zone temperature could be increased for the plant against low -temperature stress.
