Problems solved by technology

For some tree species that are difficult to reproduce, expansion and reproduction cannot be achieved
If there are no seeds, it is difficult to take root from cuttings, there is no suitable rootstock for grafting, and there are no stems or root tillers that can be used to grow seedlings by division, etc.
Secondly, the canopy of some trees is higher than the ground and cannot be propagated by ordinary layering.

Embodiment 1

[0020] (1) Branch treatment: Select 2-4 year-old branches of Osmanthus osmanthus in youth and grow vigorously, and prune them at the positions where the twigs are densely packed, and cut off the side twigs on the branches from the base or injure 1-2 branches at intervals here , the size of the wound is 0.2×0.2cm;

[0021] (2) Wrapping of branches: Wrap the branches obtained in step (1) with a 30cm×30cm plastic bag, and make the engraved part or the internode position in the middle of the package, and then add moistened peat soil (the amount of water content is 30cm by hand). water dripping from time to time) to make it evenly wrap the branches, and finally seal with a small plastic bag to achieve airtight and watertight effect;

[0022] (3) Post-wrapping management: check whether the substrate is wet one week after wrapping. The method is: pinch the wrapping by hand. If it feels soft, no need to replenish water; if it feels rough and hard, it needs to replenish water. Use a sy...

Embodiment 2

[0026] (1) Branch treatment: Select 3-year-old branches that grow vigorously in the young camellia, and prune them at the position where the branchlets are dense. The size is 0.2×0.2cm;

[0027] (2) Wrapping of branches: Wrap the branches obtained in step (1) with a 30cm×30cm plastic bag, and make the engraved part or internode position in the middle of the package, and then add moistened moss (the amount of water is when the hand is firmly grasped) Refers to the gap dripping), so that it evenly wraps the branches, and finally seals it with a small plastic bag to achieve the effect of airtight and watertight;

[0028] (3) Post-wrapping management: check whether the substrate is wet one week after wrapping. The method is: pinch the wrapping by hand. If it feels soft, no need to replenish water; if it feels rough and hard, it needs to replenish water. Use a syringe to replenish water. Seal again after replenishing water;

[0029] (4) Rooting and transplanting: cut off the bran...

Embodiment 3

[0032] (1) Branch treatment: Select 2-year-old branches of oleander in youth and grow vigorously, and prune them at the positions where the twigs are dense, and cut off the side twigs on the branches from the base or scratch 1-2 places at intervals here , the size of the wound is 0.2×0.2cm;

[0033] (2) Wrapping of branches: Wrap the branches obtained in step (1) with a 30cm×30cm plastic bag, and make the engraved part or the internode position in the middle of the package, and then add moistened vermiculite (the amount of water is about water dripping from time to time) to make it evenly wrap the branches, and finally seal with a small plastic bag to achieve airtight and watertight effect;

[0034] (3) Post-wrapping management: check whether the substrate is wet one week after wrapping. The method is: pinch the wrapping by hand. If it feels soft, no need to replenish water; if it feels rough and hard, it needs to replenish water. Use a syringe to replenish water. Seal again ...

Abstract

The present invention discloses an air layering seedling cultivating method. The air layering seedling cultivating method comprises the following steps of: (1) branch processing; (2) branch wrapping; (3) management after wrapping; and (4) rooting and transplanting. Compared with the prior art, according to the air layering seedling cultivating method, land is not occupied before rooting, propagation time is long, the whole growing season can be used for propagation, materials are easy to get, the method is simple, rooting rate and transplanting survival rate are high, and the method is especially suitable for trees which are not easy to fruit and root after cutting, have no stem tillers or root tillers for division seedling cultivation, cannot be cultivated by a grafting method, and have high crowns.

Description

technical field [0001] The invention relates to a method for raising seedlings by layering high branches, belonging to the field of seedling breeding. Background technique [0002] On the one hand, seedling production is to use the seeds of its trees for propagation, and on the other hand, it is propagated by methods such as grafting, cuttings, layering, branching, and tissue culture by a part of the organs (stems, branches, leaves, buds, roots) of the trees. For some tree species that are difficult to reproduce, expansion and reproduction cannot be realized. If there are no seeds, it is difficult to take root from cuttings, there is no suitable rootstock for grafting, and there are no tree species that can carry out branching seedlings with stem tillers or root tillers. Secondly, the canopy of some trees is higher than the ground and cannot be propagated by ordinary layering. In addition, there are few species of precious trees. Contents of the invention [0003] Purpo...
