Peach Management in Cold shed before and after Spring Festival in Beijing-Tianjin area
The main results are as follows: 1 the cold shed peach in the buckle shed period, because the cold shed peach has no cold protection facilities, only rely on daylight temperature increase and greenhouse film heat preservation, so the temperature difference between day and night is large, so the suitable greenhouse period is about February 20, so the flowering period is March 25-31, and the peach ripening period is early June. Ripening 10-15 days earlier than open-field peach. Heating type cold shed peach shed every 350 square meters, install a heating machine in the center of the cold shed, burn wood or coal, the gas is discharged out of the shed through the chimney in the middle of the furnace, and the air is preheated through the interlayer of the furnace before passing through.

At the same time, there is little difference in light time between the north and south sides of jujube trees planted in the north-south direction, but there is a great difference in the light time between the north and south sides of the jujube trees planted in the east-west direction. The difference of direction not only affects the time of receiving light, but also causes the difference of the amount of light received. From the needs of jujube planting itself, the north-south direction is the best. In addition, jujube
