Several meteorological factors were investigated under the shelters sloped 30°, 50°and 90°to the ground to know the microclimatic conditions under a shelter made the vegetables rapidly grow in winter.
No remarkable differences of air temperature were observed among the 3 experimented kinds of sheltered plots and the control.
The earth temperature of a plot with a 30°inclined shelter was the highest till the middle of January, but later a plot with a 50°showed the highest earth temperature. The control plot showed always lower earth temperature than the sheltered plots. The differences of the earth temperature among those plots became gradually smaller after the middle of February.
The most appropriate slope of shelter to the ground was investigated to maintain the earth temperature effectively under the shelter.
