Control Method of Tree Growth in Overhead Transmission Line Corridor

[0024] A method for controlling the growth of trees in the overhead transmission line corridor of the present invention, the control method includes applying plant growth regulating substances to the trees in the overhead transmission line corridor, and controlling the growth height of the trees in the overhead transmission line corridor.

[0025] In this embodiment, the plant growth regulating substance is specifically paclobutrazol, and when it is made into a solution, the solvent used is water.

[0026] In this embodiment, the trees in the corridor of the overhead power transmission line are perennial trees, specifically poplars with a tree age of 3 years (2-4 years are acceptable), and the growth speed of poplars at this age is relatively fast.

[0027] In this embodiment, 10 poplar trees are used as the implementation objects, and 2 poplar trees are used as the reference objects. The plant growth regulating substances are not applied to the reference objects, and other condit

[0033] Adopt basically the same scheme as Example 1, the only difference is that in this example, 6 1-year-old poplars are used as the implementation objects, and the amount of application is the same, generally 4L, and it can also be floated up and down by 1-2L. The concentrations were 0.4 g / L, 0.5 g / L, 0.6 g / L, 0.7 g / L, 0.8 g / L, and 0.9 g / L, respectively. It was concluded that when spraying 1-year-old poplars, the spraying concentration of plant growth regulators should be 0.5g / L-0.8g / L.

[0035] Adopt the scheme basically identical with embodiment 1, difference is only: in the present embodiment, adopt 10 poplars of 5 years old (also can be more than 5 years) age as implementation object, apply the same amount, generally adopt 10L, also can Floating 2~3L up and down, the spraying concentration is 1.3 g / L, 1.4 g / L, 1.5 g / L, 1.6 g / L, 1.7 g / L, 1.8 g / L, 1.9 g / L, 2.0 g / L , 2.1g / L, 2.2g / L. It was concluded that when spraying poplar trees aged 5 years and above, the spraying concentration of plant growth regulating substances should be 1.4g / L-2.1g / L.
