A kind of method for fast recovery of root system vitality of magnolia seedlings

Abstract

The invention provides a method for quickly restoring the vitality of the root system of magnolia seedlings, which is specifically soil ball tube film wrapping: the transplanted magnolia seedling soil balls are wrapped with PVC pipes in each row of the upper and lower layers of the soil balls, and then wrapped with film materials to connect the upper and lower layers Layer PVC pipe and wrap the soil ball; 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 wrapped with the soil ball along the upper PVC pipe; repeat every 3‑4 weeks, It can complete the quick recovery of the root system vitality of Magnolia seedlings. Adopt technical scheme of the present invention to carry out the magnolia big tree of early spring plantation, within three months, root system vigor returns to normal state from weak state; µg / (g.h), mean 17.5 µg / (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...

AI Technical Summary

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 site conditions and the ecological requirements of Magnolia, is The main reason for the difficulty of transplanting

[0005] Conventional cultivation techniques, such as raising the terrain to relatively lower the groundwater level, adding organic media to improve the soil structure, etc., are all methods of indirectly restoring and enhancing root vitality by increasing permeability and avoiding water accumulation. In the long run, they have certain effects , but the effect of quickly restoring root vitality is not obvious
