Problems solved by technology

[0006] However, these three methods have relatively large defects in practical application, which limits the large-scale application of the three methods.
For example, large-scale replacement of willow female plants in a short period of time will bring immeasurable losses to urban greening and seriously reduce the ecological benefits of urban greening; the method of high-level grafting of willows will greatly damage the greening and landscape effects of trees in the early stage, and high-level grafting of willows will It will take 2 to 3 years to restore the original greening an

Embodiment 1

[0036] In this example, Populus tomentosa with a breast diameter of 15-20 cm was selected, and the inhibitor was injected into Populus tomentosa 45 days before Populus tomentosa started flying catkins, and the injection was performed once a year according to the following steps:

[0037] (1) Inhibitor preparation: 30 g of gibberellin, 15 g of naphthalene acetic acid, and 5 g of indole butyric acid were first dissolved in 500 ml of 95% ethanol, and then diluted with 2000 ml of water to make an aqueous solution;

[0038] (2) Trunk drilling: Use a drill bit that matches the high-pressure trunk injection machine, and use an electric drill to drill 2 injection holes evenly around the diameter of the trunk at a distance of 0.2 to 1.8m. The depth of the injection hole was 2 cm into the xylem.

[0039] (3) Drug injection:

[0040] Add medicament: Add the inhibitor solution prepared in step (1) into the high-pressure trunk injection machine, seal the bottle mouth, wipe the body, and t...

Embodiment 2

[0048] In this embodiment, a weeping willow with a breast diameter of 20-50 cm is selected, and the inhibitor is injected once a year 50 days after the weeping willow starts flying catkins. The steps of the injection method are as follows:

[0049](1) Inhibitor preparation: 25g of gibberellin, 15g of naphthaleneacetic acid, and 10g of indolebutyric acid were first dissolved with 1100ml of 75% ethanol, and then diluted with 5000ml of water to make an aqueous solution;

[0050] (2) Trunk drilling: using a drill bit matched with the high-pressure trunk injection machine, use an electric drill to drill 3 injection holes evenly around the diameter of the trunk at 0.2-1.8m in the trunk. The depth of the injection hole was 2.5 cm into the xylem.

[0051] (3) Drug injection:

[0052] Adding medicine: Add the medicine solution prepared in step (1) into the high-pressure tree trunk injection machine, seal the bottle mouth after filling up, wipe the body, and then remove the air in the ...

Embodiment 3

[0058] In this embodiment, Populus tomentosa with a DBH of 55-70 cm is selected, and the inhibitor is injected once a year 10 days after Populus tomentosa starts to fly. The steps of the injection method are as follows:

[0059] (1) Inhibitor preparation: 35 g of gibberellin, 10 g of naphthalene acetic acid, and 5 g of indole butyric acid were dissolved in 750 ml of 80% acetone, and then diluted with 10,000 ml of water to make an aqueous solution;

[0060] (2) Trunk drilling: Use a drill bit that matches the high-pressure trunk injection machine, and use an electric drill to drill 4 injection holes evenly around the diameter of the trunk at 0.2-1.8m around the trunk.

[0061] All the other steps are the same as in Example 1. Finally, the amount of the injected drug was injected into each injection hole evenly according to the standard of 0.9 g of the original drug / 25 cm chest diameter of Populus tomentosa.

Abstract

The present invention provides a method for controlling pollution due to willow catkins flying in the air. It is characterized by adopting tree trunk injection method to inject chemicals. Said method includes the following steps: preparing inhibitor, boring tree trunk and injecting inhibitor.

Description

technical field [0001] The invention belongs to the application of biochemical reagents in urban landscaping biological pollution treatment, and in particular relates to a treatment method for willow catkin pollution. Background technique [0002] Poplar and willow have many advantages such as wide ecological adaptability, stress resistance and vitality, fast growth, easy reproduction, tall tree, beautiful tree shape, large shading area, and good greening effect. They have become urban greening, farmland shelterbelt construction, Key tree species for road and river bank greening. [0003] Since the founding of the People's Republic of China, especially in the 1960s and 1970s, a large number of willow trees were planted in the northern cities of China, which played an irreplaceable role in improving the ecological environment of northern Chinese cities and forming distinctive urban landscapes. [0004] However, due to historical reasons, nearly half of the poplars and most o...
