"Fragrant humble used up the world in April, hill temple peach blossom only then bloom. " this poem of Bai Juyi, a lot of friends are familiar. When go to school, geographical teacher often treats it as an example that concerns between air temperature and altitude. Normal and character, peach blossom is in the traditional Chinese calendar open March, and go up in hill, lift along with altitude because of air temperature and reduce, the florescence of peach blossom arrived with respect to defer " in April " . Now is the traditional Chinese calendar in March end, arrive immediately April, in glue east peninsula, the peach blossom of flat already withered mostly, and go up in Qingdao Lao hill, can admire this to plant " flat ' in April ' fragrant humble is used up, peach blossom of half way up the mountain only then bloom " beautiful scenery. Lao hill is glue Lai river to the south of the first high mountain, take second place of hill of elder brother Yu, moxa hill. Because hill power is continuous, the part inside Lao hill is a lot of different scene areas, be like too Ju Feng, clear, admire a mouth to wait, this peach blossom beautiful scenery, it is to be on the road of area of gigantic peak scene, specific dot is on cableway car the platform position of hill. Go toward hill from platform, in a side of step, see the peach blossom that tuft blooms. Approach to look, have a peach tree only actually. Although have this lone only, but go up in the hill that moves for mass-tone with green color, colourful red peach blossom still very conspicuous. In light of the case that opens from branch flower, florescence still can last a few days probably. And the peach blossom of flat, florescence crossed a week to control almost. Indicate the introduction of the card according to scene area, cableway car makes the same score the position of a place, height above sea level is 735 meters. Normally for, altitude every are elevatory 100 meters, temperature can drop 0.5 ℃ - 0.6 ℃ , that is to say, the air temperature here, level the land than the seaside, want low probably 4 ℃ - 5 ℃ , below this kind of circumstance, florescence defer, also be in reason. Actually, the half half way up the mountain that Lao hill is only here just, the altitude of the highest peak in a mountain range of Lao hill achieved 1132.7 meters. But summit wind is big, not likely can have the peach blossom that blooms so. A bee that the graph wanders to be near flower child, build is quite big. In this peach above, still have the white flower that tuft blooms, what write on card seeing a tree is hill Jing Zi (belong to malic subfamily) . From this bit of speculation, its florescence should be cultivated with the apple about the same, and the malic tree that levels the land now, pollination job had been finished.
