1/ ; i 2H=r 40 80cm depth sinking greenhouse. The strength of the illumination marginal effect was 8040 0cm depth sinking greenhouse, the marginal growth vigor of the three different sinking depth greenhouses was 80 40 0cm. Though the south vertical wall engendered shade in the south marginal areas of greenhouse, the sinking greenhouse of depth 80cm still had obvious advantage of heat preservation in winter and spring, and it significantly reduced the marginal effect the south of the greenhouse.The sinking greenhouse of depth 40cm to 50cm is better.
