the southern mountain area was covered by green planting reporter Huang Zhongming taken
March 12th, another tree planting day. For Ji'nan, planting afforestation this year, especially as "the spring of the city shared by the city, green lung and ecological barrier", and the south mountain afforestation with "ecological protection as the main", has attracted much attention. South Mountain, what kind of tree should be planted, what kind of forest should be planted in order to achieve the standard of green hills and green hills to realize the vision of Jinshan Yinshan Mountain, or to express the words of Liu Dongsheng, chairman of the nine Waterfall Scenic Area, "the walnut chestnut of the mountain is not a green mountain? Is it a rural tourism? "
landscape forest
the South Mountain many scenic spots"
nine like the mountain in" what ": cut off walnut chestnuts, replace the black pine
" others are busy planting trees, we are busy changing trees. " Located at Nanshan West camp, nine, such as the mountain waterfall group scenic area, deputy chief of the dangerous Bin said that locust, walnut, chestnut and other local tree species are their replacement objects. These trees or late germination, weak ornamental, or easy to cause diseases and pests. For example, the locust tree, the urban area of the spring, there is no germination here, so they imported from the northeast of the false color maple, tea maple, spruce and other more than 20 varieties, many trees began to germinate in the early March. For example, the Platycladus orientalis on the mountain is evergreen, but its winter color and tree form are not equal to those of Pinus thunbergii. "Persimmon trees, hawthorn trees, soft dates trees and other local species because of the strong ornamental, we are reservations." So far, there are more than 100 species of tree species registered in the scenic spots, of which more than 60p% are native species, and others are domestic or foreign varieties, he said.
Wei Bin said that the mountain tree is not compared to the plain, this is the sand stone mountain, the soil is very barren, and the bare root seedlings have been tried before, and the survival rate is too low, so it has to be planted with the earth ball, that is, to carry the soil back to the mountain. According to the national standard, the soil ball is 6 times the diameter of the tree DBH, and nine is 10 times that of the mountain scenic spot. For example, Lu Wu, a bare root seedling about 3 yuan, if the ball will be 14th Five-Year yuan. There are sixty or seventy professional tree planting teams in the park, planting trees all year round. In spring, seasonal workers will be hired to increase to more than 100. No large machinery can be used on the mountain, almost all shoulders shouldered. "In the past 10 years, we have planted at least 2 million trees." He said that only one tree a year, directly invested from 3 million yuan to 6 million yuan.
"we want to create a spring full of vitality, summer lush, colorful autumn, winter green full of landscape." Liu Dongsheng, the chairman of the scenic spot, does not seem to be an enterprise. It is more like studying trees. In his view, planting trees in the mountains is to be divided into stages: the first stage is that the root system is developed, the tree is second stages, the green is green, the green is the third stage, and now they are more considering the landscape formation and the biodiversity of the park.
Red Leaf Valley Happy horse ridge is also busy: increase the landscape tree species, rich forest ecology
located in Zhong Gong Red Leaf Valley, tree species are also very exquisite. In the past few years, there were more than 3000 trees and 10 thousand trees planted in the scenic spots before and after arbor day. The main seedlings are planted in the scenic area, such as the seedling of the yellow tree, the peach, the plum and so on. "Walnut chestnut and other fruit trees, we have not considered planting for several years." He said, one is not strong ornamental, two is more pests and diseases. This year, the tree planting sites open to the public are no longer in the main landscape area, and are located in relatively deserted hills. "There is no space in the main landscape area." He said.
located in Liu Bu, Pao Ma Ling is constantly creating biodiversity. "We are located in the hinterland of the Liu Bu forest farm, with a forest coverage rate of 85%. Besides the advantages of the existing animal species, the rich and three-dimensional vegetation is also being pursued." Ma Juan, the responsible person in the scenic area, said that they have 31 families and 92 species of woody plants. The main tree species are the arbor, pine, locust, maple young and other trees, as well as thorns, sour jujube, Sophora japonica, and embroidered chrysanthemum. 33 families and 103 species of herbaceous plants. There are mainly white grass, yellow grass, hay and so on. Now, from the point of planting trees, one is to increase landscape tree species, two is to increase the afforestation of bare ground by planting lawn and so on. The three is to grow shade tolerant and semi tolerant plants under forest, such as Forsythia forsythia, honeysuckle and so on. The wildlife world is moving to Zhangqiu, where it is transforming into ecotourism, holiday and leisure. "This is in line with the development direction of Southern ecological protection." Ma Juan thinks.
although the emphasis is different, but the "same" in these tourist attractions is quite obvious: by increasing or replacing tree species and building three-dimensional ecology, the scenic spots are gradually changed to "more ecological". Perhaps some people would say that compared with the whole Nanshan area, the scenic area is small. Moreover, it is understandable that scenic spots develop tourism and consume heavy money to create landscape forests. What is the inspiration for Nanshan?
