Why is expensive ancient trees expensive to introduce?

In the winter of 2011, a row of stout towering trees appeared on the western side of the Hefei-Qidong Expressway in the western suburbs of Hefei, and it became a hot topic for local residents. More than half a year has passed. People have discovered that the surrounding trees are already lush. However, these trees still look like they are bare and lifeless, making them particularly garish.

In the midsummer, the precious old trees are "sick and stagnant"

Recently, in a nursery in Jiming Village, Nangang Town, Hefei City, the reporter found the trees still covered with straw mats. It is estimated that the diameter of these trees is about 1 meter in diameter and tens of meters in height. The branches of many trees have already dried and cracked, and the tan bark begins to peel off.

According to the staff Lu Master, these trees are the crape myrtle trees introduced from Vietnam, a total of 98 trees, with an average age of about 100 years. “At the moment, it should be the season when trees are blooming. However, these valuable ancient trees still do not see a bit of vitality. It is really anxious.” Master Lu said.

Master Lu told reporters that since the beginning of this year, the health status of these trees has been very poor, and no sprouting has been seen until May. Since then, the tree's importers have also asked some experts for the ancient tree consultation, and took "drip" to supplement the nutrient solution, to increase the workers to strengthen management and protection measures, the situation is still no improvement.

When interviewed by the reporter, it was discovered that many old trees had hung up on their nutrient packs that had already been used. Some trees had as many as five or six. However, it is difficult to see workers around the trees.

In the eyes of many villagers of Jiming Village, these crape myrtle trees seem to have been "intolerable," and death has become an unavoidable fate. According to the villager Zhang Dajie, such an old tree is transplanted from south to north. The hope for survival of the tree is not very high.

The introduction of the unit to the price of old trees

According to Hu Jinshan, deputy director of the Agriculture and Forestry Water Affairs Bureau of Laoshan District, Hefei City, Nangang Town of Hefei City introduced a greening company named Bada Garden Construction Co., Ltd. from Jiangsu in 2011. Through the land circulation method, seedling planting was carried out and a one-time contract was signed. Mu land.

According to the plan, the nursery of the old crape myrtle tree will be built by Bada Company to build a nursery stock boutique garden covering an area of ​​500 mu. The construction period will be one year. The initial planned investment will be 130 million yuan. The main plants will be cherry, black pine, sweet-scented osmanthus and crape myrtle. The goal is to create a tourism eco-tourism park at the west gate of Hefei.

The reporter found that when the ancient crape myrtle tree arrived in Hefei, it was referred to by the local media as "the sky-high price of ancient trees." According to the introduction cost reported at the time, each tree was worth nearly 400,000 yuan. Then the thousands of miles of "marrying" in Anhui this group of crape myrtle trees exactly value? In the face of reporters' problems, Li Kangsheng, the head of the boutique park, was extremely quiet.

“The large-scale tree transaction is an agreement between the two parties, and the tree is based on the cost of transportation costs.” Wang Hua, a teacher at the Anhui Agricultural University's College of Horticulture who has been engaged in landscaping research for many years, told reporters: “The crape myrtle tree is a valuable environmental protection plant in China and is a century old. The price of the old tree market should be estimated at several hundred thousand yuan.

During the interview, Li Kangsheng admits to the reporter that these old crape myrtle trees were indeed badly considered at the beginning of transplanting. “Hefei has low temperatures in winter, and the trunks of transplanted trees are large, and there is no rooting in the underground, which causes difficulties in transporting water and nutrients upwards, which will cause the current situation.” Li Kangsheng said.

Transplanting seedlings requires scientific rationality

It is understood that the crape myrtle tree usually blooms in summer and autumn every year. The flowering period is as long as four months and its color is bright. Therefore, it is often used for bonsai bonsai or ornamental gardens and has a broad market prospect. Speaking of the original intention of the boutique park to introduce 100-year-old crape myrtle trees from Vietnam, Li Kangsheng said that it was precisely because of the fancy and economic benefits of the crape myrtle tree.

However, in Wang Hua’s view, the large-scale transplantation of Lagerstroemia cross-latitude for a century-old boutique garden is actually very unscientific. The so-called “Tangerine Health Huainan is an orange, born in Huaibei is a badger”, especially for the transplantation of rare species. Careful, small-scale trials must be conducted prior to introduction, and the introduction process should also be carried out step-by-step.

Hu Jinshan also agreed with this view. He told reporters that transplanting ancient trees within the jurisdiction is generally not allowed. This is due to the fact that the transplanting of ancient trees has a series of strict requirements in our country. On the other hand, it is also technically more difficult. Such large-scale transplants of old trees like the Lagerstroemia crassipes tree, as the forestry authorities, are not dare to try it.

Well, knowing that companies have introduced such tree species with great risks, why did the Lanshan District Agriculture and Forestry Water Bureau agree to the introduction? In this regard, Hu Jinshan is helpless. “The formalities of the enterprise are legal, and each inspection pass meets the requirements. Enterprises have autonomy. After the trees are introduced, we can only conduct technical guidance.” said Hu Jinshan.

According to Wang Hua, in recent years, with the acceleration of the urbanization process in China, the demand for landscape tree species has been increasing, and the seedling economy has also shown an increasing trend of warming. However, with the active foreign exchange market transactions, in the long-distance transplanting of nursery stocks, especially precious tree species, some companies have blindly pursued economic interests while neglecting the survival rate of trees. In this regard, Wang Hua believes: "Only rational transplantation within the scope of technical conditions can guarantee the market to achieve healthy and sustainable development."
