Key management points for cold-frame peaches in the Beijing-Tianjin region around the Spring Festival
1. Frame-covering period. Because cold-frame peaches have no cold-protection facilities and rely solely on sunlight for warming and the frame film for insulation, the day-night temperature difference is large. The frame-covering period should preferably be around February 20, so that the flowering period is March 25-31 and the peach ripening period is early June, 10-15 days earlier than open-field peaches. For heated cold-frame peach sheds, install 1 heater per 350-450 sq m at the center of the cold frame, burning wood or coal; the gas is discharged outside the frame through the chimney in the middle of the stove, and the air is preheated through the stove's interlayer and then
