Matters needing attention in transplanting metasequoia glyptostroboides

Metasequoia glyptostroboides is a plant with high demand for soil, a very precious and cherished plant, and it is also one of the plants that have lived on the earth for a long time. With the demand for metasequoia, many metasequoia need to be transplanted. so what do we need to pay special attention to in the process of transplanting?

Transplanting season of Metasequoia glyptostroboides

Metasequoia glyptostroboides is a fast-growing deciduous tree with deep roots and luxuriant leaves, strong ability of root germination and regeneration, and strong activity of leaf photosynthesis, respiration and transpiration in aboveground parts. From the ecological point of view, it is the best season for transplanting metasequoia trees from the period from falling leaves in autumn to the development of new buds in spring next year.

Selection, excavation and Transportation of Transplant seedlings of Metasequoia glyptostroboides

1. The choice of metasequoia. Metasequoia glyptostroboides is a fast-growing deciduous tree with high trunk. In the selection of seedling source, the seedlings with sparse planting density, low branching point, symmetrical tree shape and good growth should be selected as transplant seedlings.

two。 The size of the earth ball and digging. The size and excavation of soil balls are the key to the success or failure of transplanting metasequoia trees. Generally, the diameter of the soil ball is 6 ~ 8 times of the DBH of the tree, and the height of the soil ball is 65% ~ 80% of the diameter of the soil ball. When digging, when you encounter a thicker lateral root, the root is cut off with a saw or shears, and the saw is cut flat with a sharp knife. The earth ball should be dug into a gyroscope, and the soil ball should be fastened with leather rope to prevent the soil ball from being loose during transportation.

3. Hoisting and transportation. The lifting and transportation of big trees is one of the important links in transplantation. when lifting, the key is to protect the mud ball from loose and bark from damage. When loading and placing, the mud ball should be firm without rolling, at the same time, the trunk or crown in contact with the trunk should be protected by soft material, and the tree should be fixed with rope. In the process of transportation, it is necessary to cover with cloth to minimize the evaporation of water.

Matters needing attention in transplanting metasequoia glyptostroboides

1. Pruning and sprouting before planting. One of the keys to improve the transplanting survival rate of Metasequoia glyptostroboides is to reduce water transpiration by pruning, sprouting and trunk bandaging.

Metasequoia glyptostroboides has strong tillering ability and resistance to pruning, so transplanting metasequoia trees should be strongly pruned before planting. First, for over-dense branches, the branches should be thinned according to the longitudinal spacing of 30 to 40 meters, and the large side branches should be retained. The branches left by the whole tree should not exceed 1 / 5 of the original tree, the orientation and position of the reserved branches should be reasonable, and the integrity of the overall tree shape should be ensured. The second is to wipe the buds of the reserved branches, leaving only 5 ~ 7 buds at the top. After pruning, the cut of the big branch is treated in time, and the common method is to apply white paint, paraffin or tie it with plastic cloth.

Due to the high trunk of Metasequoia glyptostroboides, wet grass rope, flax and other materials used for transportation closely wrap the trunk, which has a certain degree of moisture and heat preservation to the trunk, and the drying height should be more than 1 inch 2 of the height of the whole trunk.

two。 Digging holes. If the soil is sticky, the size of the tree hole should be enlarged according to the actual situation, the pre-backfilled soil should be loose loam, and the pre-backfilled soil should be mixed with slag or coarse sand to increase the water permeability and air permeability of the soil. The tree holes dug were filled with water the night before planting, and the next morning, water leakage and leakage were checked, and the loopholes were plugged in time when they were found to be leaking.

3. Planting. Hang the tree carefully in the prepared planting hole, remove the rope tied to the tree trunk, set up the trunk, adjust the main ornamental side of the crown, put it into the hole, straighten it, and temporarily pull it with wire or grass rope to prevent seedling dumping and remove mud ball bindings and part of the grass rope.

The planting of the seedlings is divided into two backfilling stages. The first time the soil ball is first backfilled with the planting soil of 1x3px2, watering and mixing into mud; after the mud is semi-dry, the planting soil is backfilled for the second time, and the cofferdam is made.

4. Support, fix. Big trees should be supported and fixed immediately after planting to prevent dumping. It is better to support the tree at about 3 places with a height of 1, 2 and 2, and add a protective layer to prevent skin injury. If it is planted in pieces and regularly, and the density is relatively high, it can be connected vertically and horizontally with bamboo at the height of 2 ~ 2.5 meters, and then diagonally braced with logs in different directions under the inside, so that the support is not only stable, but also saves materials.
