Control method for iron-deficient chlorosis of greening trees

Abstract

The invention relates to a control method for iron-deficient chlorosis of greening trees. One or more containers filled with a ferrous sulfate solution are embedded under a tree, one or more absorption roots of the tree are inserted into the container(s) to continuously absorb the ferrous sulfate, the absorption roots are selected from absorption roots of corresponding roots of the bough of the tree, the number of the containers buried under the tree is one or above, the container(s) is (are) preferably located below the bough, needing iron supplement, of the tree, and a mutual correspondencebetween the bough of the tree and underground main roots is used to make the corresponding roots directly absorb the ferrous sulfate solution in order to achieve effective and sufficient absorption offerrous sulfate and effectively change the iron deficiency of the trees, so the iron-deficient chlorosis is effectively prevented and overcome, and the method can play a role for a long term to solvethe iron-deficient chlorosis problem at a time. The method has the advantages of simplicity in implementation, long acting time, and ensuring of good effects.

Description

technical field [0001] The invention relates to a method for controlling iron-deficiency yellowing of green trees. Background technique [0002] With the in-depth development of greening and beautifying cities, cities and towns around the world are building forest cities and garden towns. Due to the big difference between cities and villages, urban road traffic includes sidewalks, non-motorized lanes and motorized lanes. Outside the small junction, the narrow separation belt between the main road and the auxiliary road is also separated by a green belt, and some roads are also separated by a green belt between two-way lanes. Since the roadbed needs to be rolled continuously during the construction of the road, and the graded sandstone is laid and rolled, and then concrete is poured, and the construction process is dominated by large machinery, so it is not possible to plant large trees in the narrow isolation zone. Satisfy the soil and nutrients needed by trees. In additio...

Problems solved by technology

At the same time, because the road green belt is in a narrow and long range, and there are other trees and shrubs covered, so, no matter from the root system or other trees, this method is not feasible

Even if ferrous phosphate is applied after digging other trees and shrubs, the effect will not be ideal due to insufficient root system area, and it will treat the symptoms but not the root cause after implementation;

[0014] 3) Trunk injection of 0.3%-0.5% ferrous sulfate solution has a certain effect on trees with light disease, but the effect on trees with severe yellowing is not ideal, and the treatment effect is only one year, which cannot achieve the purpose of fundamental treatment;

As mentioned above, this method should only be used before tree planting or in potted flowers
