Description

Technical Field

[0001] The invention relates to the technical field of ancient tree transplantation, in particular to a method for bare-root transplantation of ancient trees under special circumstances. Background Art

[0002] Transplanting ancient trees is a crucial component of ecological conservation and urban development. However, traditional transplantation methods rely on soil balls to protect the roots, making them difficult to implement in challenging environments (e.g., geological disasters, harsh geographical conditions, typhoon-induced lodging, and other conditions where soil balls cannot be transported). Among existing technologies, CN118303288A proposes full-crown bare-root transplantation, improving survival rates through moisturizing and root pruning, but it fails to address root corrosion and soil compatibility in harsh environments. CN104719085A employs root removal followed by application of rooting powder, but this method is inadequate for treating the complex, decaying roots of ancient trees and lacks solutions for specialized soils. While CN108184519A introduces water-retaining agents and anti-transpiration agents, it fails to address the low soil-root adhesion after bare-root transplantation.

[0003] The traditional bare-root transplant method has the following defects:

[0004] Rough root treatment: relying solely on simple pruning and rooting agents, which cannot effectively inhibit rot and activate dormant roots;

[0005] Poor soil adaptability: The original soil characteristics of the ancient tree were not taken into consideration, resulting in difficulty in integrating the root system with the soil of the transplanted site;

[0006] Insufficient support and maintenance: The support structure can easily damage the bark, and the single root-fixing watering method makes it difficult to keep the roots moist;

[0007] Low survival rate: The survival rate of existing methods is less than 5% under special circumstances, and trees are prone to die due to interruption of nutrient supply after transplantation.

[0008] Therefore, there is an urgent need for a bare-root transplantation method for ancient trees in special environments to solve the above problems through systematic technical improvements. Summary of the Invention

[0009] The present invention aims to solve the above problems and proposes a bare-root transplantation method for ancient trees under special conditions, which significantly improves the transplant survival rate through root activation, soil optimization and refined maintenance.

[0010] The technical solution of the present invention is achieved as follows:

[0011] The bare-root transplantation method for ancient trees under special circumstances includes the following steps:

[0012] S1: Root pretreatment: trim rotten and damaged roots, retaining fibrous roots;

[0013] S2: Sterilization and antiseptic treatment: Spray the bare roots with a mixed solution of carbendazim, metalaxyl and phosphine-aluminum to sterilize, disinfect and antiseptic the entire bare root tray;

[0014] S3: Root activation treatment: Use a mixture of strong rooting agent, glucose, amino acids and tartaric acid to brush the root system 3-5 times, with an interval of 2-3 hours between each time, to awaken the germination power of the plant root system, so that new roots will sprout as soon as possible after transplanting and provide nutrition for the tree;

[0015] S4: Wound closure: Use healing cream to seal all root cuts and damaged parts to promote rapid healing of the cuts and damaged parts to prevent rot;

[0016] S5: Planting soil treatment: Select clean, unpolluted, slightly acidic red soil, lay a gravel cushion and fill it with organic fertilizer before planting;

[0017] S6: Manual soil filling: Manually fill the red soil into the root plate pores to make the root system and soil completely close together, surround the soil in layers and build a watering pool to prevent water loss during later maintenance and watering;

[0018] S7: Support and fixation: Use four-way rubber pads to support the structure to prevent the bark from being damaged when tying, and reinforce the bottom with wooden stakes to prevent the tree from falling due to wind;

[0019] S8: Rooting water maintenance: Water the roots thoroughly in stages, and keep the crown and trunk moisturized simultaneously;

[0020] S9: Shading and post-maintenance: After planting, build a shade net 1.5-2 meters away from the tree at the end of June. The shade net is like a cover covering the outside of the tree, and the shade net is 50-100cm higher than the top of the tree. Observe and adjust maintenance measures regularly.

[0021] Furthermore, the mixed solution in step S2 is compounded by 1000 mg / L of carbendazim, 500 mg / L of metalaxyl and 300 mg / L of fosetyl aluminum, and is sprayed until the root system is completely wetted.

[0022] Furthermore, the mixed solution in step S3 comprises, by weight, 3-5 parts of a strong rooting agent, 10-15 parts of glucose, 5-8 parts of amino acids, 2-3 parts of tartaric acid, and the remainder is water.

[0023] Furthermore, the red soil in step S5 needs to be sieved to a particle size of ≤5 mm, and the organic fertilizer is a mixture of decomposed cattle and sheep manure and humus in a ratio of 1:2.

[0024] Furthermore, in step S6, the root plate is surrounded by soil with a thickness of 30-40 cm, and then soil is surrounded on top of the soil layer to form a watering pool so that the water will not be lost during subsequent maintenance and watering.

[0025] Furthermore, the support structure in step S7 includes four fir support poles with a length of 1 / 3 of the tree height, the support point is 1 / 4 of the tree height from the ground, and the binding parts are padded with 3-5mm thick rubber sheets to prevent damage to the bark.

[0026] Furthermore, in step S8, the watering pool is reinforced before watering to prevent the water from washing away the outer periphery of the pool and affecting the later maintenance. Watering is maintained at 6-7 times / month.

[0027] Furthermore, the root growth condition is checked one month after transplanting. When rice-sized root buds appear near the root cut, normal maintenance is carried out. When there are no root buds at the root cut, large tree nutrient solution is hung on the tree to provide nutrients for the tree, promote tree survival, and prolong root growth time.

[0028] By adopting the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The mixed activator promotes the differentiation of root primordium. New root buds the size of rice grains can be observed 30 days after transplantation, which promotes the rapid regeneration of the root system of the old tree after transplantation.

[0030] 2. The mixed solution of carbendazim and metalaxyl effectively inhibits fungal and saprophytic infections, making the rhizomes more resistant to decay and improving the survival rate after transplanting;

[0031] 3. High soil adaptability, slightly acidic red soil combined with organic fertilizer, enhances water retention and air permeability, and promotes close integration of roots and soil;

[0032] 4. The four-way rubber support structure prevents mechanical damage, and the wooden piles are reinforced to resist the impact of wind, which improves the stability of the ancient tree and prevents it from falling. DETAILED DESCRIPTION
