1Select the best transplanting time
Generally selected in the early spring, if it is transplanted seedlings in autumn and winter, in the north will have to do a good job of trees and soil protection and cold measures.
2 With the digging
Seedlings should be kept as short as possible after the excavation of seedlings, and care should be taken if they need to be transported. Where the distance between the original seedlings and the transplanted land is closer, the seedlings will be planted. In transportation, seedlings can be sprayed with anti-transpiration agent, root earth ball, leaf spray water insulation or sunshade and other measures to reduce the consumption of tree organic matter, to ensure the normal regeneration of root hair, of course, Xiaobian is the best choice is the best seedlings , to better ensure the survival of the whole crown transplanted seedlings.
3 watering, surrounding soil
After the seedlings are planted, they are poured 3 times permeated with water, and the first water is poured in 24 hours after planting to promote the development of the root system. After 2 to 3 days, the water is poured 2 times, after 1 week, the water is poured 3 times, and the leaf is sprayed regularly. Significantly increase the survival rate of transplanted seedlings after transplanting.
4 trim
When pruning, only sparse shearing or short shearing methods are applied to the seedlings to ensure the branches of the seedlings and to control the tree vigor so that the plants can be restored and grow in a short period of time, so as to achieve the overdue greening effect. When planting, the weak, leggy, dry shoots, and branches of diseases and insects that grow within the coronal section are first trimmed off, and then the same-direction branches and cross-section branches of the plant are sparsely maintained. At the same time, parallel branches and overlapping branches within the crown of the plant are also to be cut. , Pruning branches, erect branches, hanging branches, leggy branches, etc.
5 Fertilization
After transplanting, the whole seedling of nursery stock can be used to supplement tree nutrients through root fertilization. The method of fertilization is to mix the backfill with organic fertilizer. After the first watering, the organic fertilizer is applied in the tree cave to meet the demand of the tree. It is necessary to pay attention to The amount of fertilizer should not be too much or too little, and the amount of fertilizer should be reasonably known.
6 root protection
When the bare root seedlings are excavated, all the roots outside the reserved root system should be cut off, excavated with earth balls, and the main root should be removed in the root hair area to ensure that the root crown, meristematic zone, and elongation zone are intact. After the seedlings are unearthed, apply a wound healing agent to the exposed roots to prevent the roots from being infected by bacteria and causing rot. This will affect the survival of seedlings.
7 Use anti-transpiration agent to reduce tree metabolism
After transplanting, transporting, storing, and transplanting, seedlings should be shaded so as to reduce photosynthetic rate and reduce tree nutrient consumption.
For the canopy, appropriate sparse leaves should be carried out to reduce the transpiration of leaves;
Foliar spraying anti-transpiration agent to inhibit leaf transpiration;
The trunk is tied with a straw rope to reduce the transpiration of the trunk.
8 tree cavities, backfill soil and earthworms
The specifications of the planting hole should be based on the size of the root system and soil ball. The trees need to be planted when planting. The depth of the planting is generally flat or deep with the original soil mark 5cm; when filling the soil to 1/2 of the pit, the seedlings will be gently Several times, fill in soil, compaction; backfilling soil needs to be "three steps" when it is planted: Step 1, the depth of planting is generally flat or deep with the original soil mark, filling is 1/3 of the tree pit, filling Moderate compaction; Step 2, fill in 2/3 of the tree pit, fill the soil after moderate compaction; Step 3, filling the tree pit will be full, and moderately compacted, surrounded by good soil.
9 Post-plant management
After the seedlings are planted in the early stage, management of irrigation, loose soil, fertilization, pests and diseases, pruning, etc. in the later period is required, and management methods such as trunk healing, tree-hole repair, whitening, shading, stem winding, and root and soil pile are adopted, or The use of tree injection of nutrient solution, root spray hormone and other special methods to meet the needs of seedling growth conditions, improve the survival rate of seedlings.
