Green Plant Garden of the winter safely, "difficulty"
Have colorful flowers, rare plants gathered in the Green Expo Garden is facing a huge challenge, how to plant the winter? Reporter discovered yesterday in an interview, Green Expo Park have been a tree, bamboo and other deaths. In the face of limited funds, like those trees in a foreign land to all the winter is, indeed, a green Garden of management headache for the problem.
Some plants, trees withered
Green Expo Garden beautiful than before, and this is yesterday's news came to the scene of first impression. Down the door going into it, was originally a "flower river" by journalists to observe carefully, passing the million pots of potted plant, at least 1 / 3 have been dead, and the rest are dying. A small hand-pushed carts of the workers came, the car piled has withered plants, there are tea, pomegranate trees. The workers said the two days the park is on the dead plants were replaced, the less he alone must pull 89 times a day.
Green Expo Garden in the northeastern side of the main exhibition hall, a long row of bamboo cane, as dry as kneeling at the door, with no anger. Cao, Deputy Director said that due to the rush rush period, all-season planting bamboo, many bamboos transplant too late to quit before transplanting, pruning is also relatively simple, so the survival rate affected.
Bo Park's random walk in the green half-circle, to see a lot of branches of trees had dried up. In the service area behind the main exhibition hall, there obviously dead, more than ten laurel Trees. It is cleaner that the dead tree like other places there are in the Green Expo Garden.
Rare plant winter headache
Green Expo Park were planted 24,200 large trees, 150,000 shrubs, flowers, more than 40,000 strains of bamboo, over 600 kinds of trees. How to winter these plants? This reporter learned that the Green Expo Park features 42 gardens, 15% of the Green Garden of the South of rare plant species, growth temperature to 15 ? 20 only appropriate, Nanjing winter a serious threat to natural climatic conditions The growth of plants.
Green Expo Garden has now developed a program for the winter plants, two types of programs, namely conservation and alternative classification winter replanting. For the part of the strong cold hardiness of plants, such as cycads, Canada, date palm, etc., to set the wind barrier, wrapping materials, cold in situ conservation, which allows the plant to wear "coat." The weak cold hardiness, but the high cost of viewing and purchase of plants, then go directly to the greenhouse, such as Cyathea, Washington palm, Ficus, San Weikui, Phnom Penh, agave, plants such as Sedum. Cold weak, but a general view and purchase costs, or the zonal characteristics of clear, protective measures difficult to implement a one-time display of plants, under greenhouse capacity and protection costs, taking a general winter protection. To keep plants growing outside a south attractions landscape effect, plant in the winter need to burglary removed, will remain the framework of the original plant layout, with other plants with similar replacement. According to reports, for many rare plants, many garden experts also the first to see, so their conservation is quite nerve-racking.
Common plant life on the line
Some rare plants can be moved into the greenhouse, more common plants how to do? Cao, Deputy Director, explained that only some routine maintenance such as pruning, fertilization and so on. This reporter learned that initially identified the current Green Garden of winter maintenance costs of plants in the 500,000 yuan. In this regard, Nanjing Forestry University, Professor Tang Gengguo that Green Garden of the winter program developed by the Nanjing plant is basically feasible, but must protect the capital investment. As from Hainan, Shenzhen, Guizhou area of precious species, light moved into the greenhouse would cost a lot, Garden of 500,000 yuan on the winter green fee is clearly not enough. Given the limited winter fee with rare species of plants are not fully satisfied, and then park the greenhouse will be "loaded", then the majority of the plants had to be cold outside, can see good luck on surviving the.
Park Founder application maintenance costs
It is understood that, since October 16 after the closing of the Green Fair, Green Garden of Nanjing has been handed over to management. Yesterday reporters contacted the relevant person in charge of Nanjing Bureau of Parks, received the reply was that after the end of the Green Fair, has been transferred to the Hexi headquarters management, and Forestry and Park Service no longer intervene. Green Expo Garden of Cao Zhuren said, because just take over a year of light on the garden plants, grass and other maintenance is a huge cost, not stuck atop a thousand million. Currently, the cost of the operation of Green Garden of maintaining all the command from the Hexi Corridor, but they are actively to apply for green maintenance fees, if approved down, the pressure will be small.
