Problems solved by technology

Under normal circumstances, it takes one year or more to restore the root system of magnolia, and it may even be in a weak or weak state for a long time, resulting in poor growth of the tree for a long time
[0004] During the transplanting process, the damage to the root system caused by the digging of large seedlings, plus the possible damage during loading, unloading and transportation; the difference between the planting site conditions and the original environment, especially the large difference between the planting s

Embodiment 2

[0032] A method for fast recovery of root vigor of Magnolia seedlings, comprising the steps of:

[0033] (1) Soil ball tube film wrapping: Wrap the transplanted white magnolia seedling soil balls with PVC pipes on the upper and lower layers of the soil balls, and then wrap the PVC pipes on the upper and lower layers with film materials and wrap the soil balls, with the nozzle of the upper layer facing upwards Leaking out of the soil surface, the lower pipe flows into the drainage ditch from the bottom of the tree hole with a slope of 5°;

[0034] (2) Nutrient solution perfusion: inject the nutrient solution composed of hormones, trace elements and fertilizers into the PVC pipe from the upper port, and penetrate into the film covering the soil ball along the upper PVC pipe; the film material is carboxymethylated nanofiber The grafted anionic polyacrylamide has a molecular weight of 80,000 after grafting, and a titanium dioxide antibacterial agent with a mass fraction of 0.001% ...

Abstract

The invention provides a method for rapidly restoring root activity of Magnolia denudata seedlings. The method specifically comprises the following steps: coating soil balls with pipes and films: upper and lower layers of transplanted Magnolia denudata seedling soil balls are wound with the PVC pipes, and then the films are used for connecting the upper and lower PVC pipes and coating the soil balls; injecting a nutrient liquid: the nutrient liquid containing hormone, trace elements and fertilizer is injected into the PVC pipes from top openings and permeates the film coating the soil balls from the upper PVC pipe; repeating the last step every 3-4 weeks to rapidly restore the root activity of the Magnolia denudata seedlings. By adopting the technical scheme for Magnolia denudata trees planted in early spring, the root activity is restored from weak state to normal stage within 3 months or improved from weaker state to strong state (the root reduction intensity is 15-20 mu g/(g.h) andthe average value is 17.5 mu g/(g.h)).

Description

technical field [0001] The invention relates to a method for rapidly recovering root system activity of magnolia seedlings, in particular to a method for quickly recovering root system activity of large-scale magnolia seedlings after transplantation. Background technique [0002] The root system of magnolia is fleshy, not resistant to water and humidity, and is more sensitive to saline-alkaline soil. After transplanting large-scale seedlings, due to lack of soil nutrients, poor ventilation and drainage, etc., the root system vitality decreases and the recovery is slow. [0003] Magnolia magnolia root damage caused by root cutting during transplanting; planting site conditions do not conform to the ecological habits of magnolia trees, for example, the pH of the soil is alkaline, the soil is heavy and causes poor ventilation, and the terrain is low or The high groundwater level causes poor drainage and lack of soil nutrients, which cause the root system of magnolia to be under...
