Embodiment 1

[0042] 1. Selection of implementation site

[0043] The implementation site is located in Slender West Lake---Shugang Scenic Area, Yangzhou City, Jiangsu Province, with subtropical warm climate, annual average temperature of 14.8°C, annual average frost-free period of 220 days, average sunshine of 2140 hours, and annual precipitation of 1030mm. Alluvial plain, sandy loam, soil moisture content about 60%.

Embodiment approach

[0045] (1) Mark root removal: mark the south side of the tree body in the original place with red paint.

[0046] (2) Digging and thinning: Dig the soil ball with 10-12 times the DBH of the tree to be transplanted, and remove 1 / 3 of the branches except the top branches after falling to the ground.

[0047] (3) Laying water pipes: Lay water diversion pipes along the trunk to 2 meters from the top of the tree, place micro-sprinklers to humidify the canopy, and connect the annular pipe humidification device to humidify the trunk;

[0048] The annular tube humidification device, such as figure 1 , figure 2 As shown, it includes a water diversion pipe 1 and an annular sprinkler pipe 2. The water diversion pipe 1 is laid from bottom to top along the trunk. The annular sprinkler pipe 2 is an annular water pipe that surrounds the trunk. Passage 5 is fixed, and this annular sprinkling pipe 2 is provided with 5 drain holes 4 near the inside of the trunk or below, with a diameter of 0...

Abstract

The invention discloses a cultivation method for improving the survival rate of full crown transplantation of metasequoia trees. Including: 1) Indicating the north-south orientation of the original site of the tree body; 2) The diameter of the soil ball is 10-12 times the DBH of the transplanted tree; 3) Thinning 1 / 3 of the branches except the top branches from bottom to top; 4) A micro-sprinkler is placed on the top of the tree to keep the crown moisturized, and an annular pipe humidification device is laid on the trunk; 5) The bottom of the planting hole is cross-laid with a nylon mesh breathable belt; 6) The tree is planted according to the north-south orientation of the original place of the tree, and the surroundings of the planting hole are filled to retain water and increase the root 7) Small-leaved ivy is planted at the base of the trunk to climb and protect the trunk; 8) The tree trunk is connected in a network of steel pipes to ensure the safety and stability of the tree body; 9) Regular tending and management. The cultivation method of the present invention is simple and easy to implement, and is especially suitable for urgent large tree migration and transplanting projects with insufficient root removal and maintenance. It can effectively improve the bad transplanting conditions in which the high temperature environment in the growing season accelerates plant water transpiration, and can improve the health of 40-year-old Metasequoia trees in spring. The survival rate of migratory crown transplanting is over 90%.

Description

technical field [0001] The invention relates to a cultivation method for transplanting full crowns of trees, in particular to a cultivation method for improving the survival rate of transplanting full crowns of metasequoia trees, and belongs to the technical field of plant cultivation. Background technique [0002] Metasequoia is a relic and precious tree species native to China. It is the first batch of rare species listed as the first-class national protected plants. It is known as the "living fossil" of the plant kingdom. It is widely used in parks, roads, squares and other places. Group planting has outstanding landscape effects. [0003] However, the low survival rate of the full crown transplantation of metasequoia trees is a difficult problem in migratory transplanting projects. The average survival rate is generally below 30%, which limits the safe migration and utilization of metasequoia trees to a large extent. Contents of the invention [0004] The object of th...
