Analysis on the key points of transplanting technology of Cinnamomum chinense

Cinnamomum camphora tree has dense branches and leaves, thick crown and shade, majestic tree posture, can smoke dust, conserve water, fix soil and prevent sand and beautify the environment. As an excellent tree species of urban greening, it is often necessary to transplant. If the transplanting technology is not good enough, it will greatly increase the probability of transplanting failure. The following is the analysis of the main technical points of camphor tree transplantation for you.

1. Moisturizing measures of seedlings in the process of transportation

⑴ defoliation

Use a bamboo stick to knock off the leaves in the air, or remove the leaves immediately before getting on the bus.

⑵ cotton cloth moisturizing

After getting on the bus, the big tree is covered with cotton cloth and watered to maintain humidity, and the soil ball should also be covered with wet cotton cloth and watered after getting on the car.

⑶ shading

Cover it with a dark net, and it's best to drive at night near the road.

two。 Tree relocation and maintenance

If the tree is moved, the tree should be fully watered one day, and the tree should be cut after draught, and the leaves and trunks should be covered with anti-steaming protective agent (transpirant). The branches should be covered with cotton cloth and watered. If it is not hit in advance (anti-steaming protective agent), the cuttings will not work. In the process of moving the tree, first of all, the fine root can not be dehydrated, the nutrition and water are absorbed by the fine root and fleshy root, and the big root is rooted later by photosynthesis. Generally, it is not a problem to transplant camphor. He has enough fine roots to absorb water and supply big trees.

Such as Shuilao area planting, the bottom of a little deeper square stone, prevent water, rotten roots, plant the back frame on the black net, must spray water to the tree every day when the sun goes down the mountain.

3. Practical experience

Pan Changzhi, general manager of black rose (rose) flower research in Keqiao District, Shaoxing City: some people say that Shandong camphor is going to freeze to death. Pan Changzhi thinks that it mainly depends on the tree species, and the trees in the transplanted Xiaoshan paddy land will not freeze to death, but the camphor in the hills and mountains will definitely freeze to death. The camphor in the hilly woodland has only thick roots and straight roots, and there is no water in the upper part of the soil in the summer, so it desperately puts down the main root and absorbs water to supply the whole crown, so it has only a few total roots when it is transplanted, and there are no fine roots after cutting. There is a greater chance of transplanting to the south, such as northern Anhui, Henan and Shandong. Camphor is planted here, and it will die if it doesn't die this year or next year. This is the reason why some economic people do not understand technology and only fight for money, which leads to the total annihilation of camphor in the north.

Liu Yunzhan, vice president of Shangqiu Garden and Flower Chamber of Commerce, said: it is best to cover all the leaves as far as possible during transportation, and it is best to knock out all the leaves a week before the seedlings are raised, and new buds can be sent out about 20 days after planting. If the transplant lasts for three years, the survival rate will not be a problem. Try to spray fungicides on the crown before planting, such as carbendazim, because camphor new branches in 2012 are prone to disease black pole, once the pole is black, the infection is fast, the basic survival is very difficult, can control the 20 inner pole is not black, the survival rate can be greatly improved.
