Embodiment 1

[0031] In order to study the germination characteristics of poplar trees after felling, the project team investigated the germination characteristics of 36 poplar tree stumps located under the 220 kV transmission line in Shiqiu Town, Lishui County, in order to explore the germination of poplar trees, the height of the felling stumps and the cutting heights. The relationship between the circumference (or diameter) of the pile was investigated on April 1, 2008.

[0032] from figure 1 It can be seen that there is no significant linear correlation between the height of the stump sprout and the height of the stump, but there is a certain nonlinear relationship. When the pile height is lower than 20cm or higher than 100cm, the maximum sprout height of each pile exceeds 150cm; when the pile height is about 60cm, the sprout height is the lowest; when the pile height is between 50cm and 70cm, the maximum sprout height of each pile The height of sprouts is less than 100cm. The results...

Embodiment 2

[0036] Example 2 Effect test of inhibitor spraying before poplar stump germination

[0037] The test point of this test is selected under the Xuzhou transmission line. The age of poplar before felling is 4 years old. There are 4 kinds of selected inhibitors, namely glyphosate, paclobutrazol, chlormethalin and Bijiu.

[0038] According to the existing research data, on the jujube tree without girdling during the flowering period, when the jujube before flowering is hanging with 8 to 9 leaves, use 2000 to 3000 mg·L -1 The paclobutrazol was sprayed on the whole tree, and the fruit setting rate was more than 2 times higher than that of the control; the whole tree was sprayed with 2500 mg·L before flowering or early flowering. -1 Chlormetrodin (CCC) can effectively control the growth of jujube heads, and the fruit setting rate is more than 2 times higher than that of the control. [46-47] . Paclobutrazol 2000mg·kg -1 It can well promote the early flowering of peach saplings and...

Embodiment 3

[0048] Example 3 Effect test of inhibitor soil application before germination of poplar stump

[0049] The test site for this test is selected under the Dangquan-Danghui 500 kV transmission line in Lishui County, Nanjing City. Poplar trees are 5 years old before felling. According to the test results of the Xuzhou site, two reagents, chlormethalin and bijiu, were removed, and glyphosate and paclobutrazol were retained. In addition, an inhibitor, cycloazinone, was added, that is, three kinds of inhibitors were selected for the test. The results of the Xuzhou point experiment showed that high concentrations of inhibitors (such as 2000 mg·L) -1 The above) have obvious inhibitory effects on the germination of poplar stumps and the growth of sprouts. Considering the possible impact of the degradation and residue of the inhibitor on the ecological environment, if a lower concentration of the inhibitor also has an inhibitory effect, then reducing the application concentration will ...

Abstract

The invention discloses a method for inhibiting growth of a poplar tree stump. According to the method, after a poplar tree is cut, an inhibitor is applied. Compared with the prior art, the method hasthe advantages that the investment of manpower and material resources is greatly reduced; germination and regeneration of the tree stump are inhibited, or growth of the poplar tree is delayed, maintenance cost of power transmission lines is reduced, and social contradiction caused by sawing trees is reduced, "contradiction between trees and lines" is transformed to " harmony between trees and lines", and therefore, safe and reliable operation of power transmission lines is guaranteed.

Description

technical field [0001] The invention belongs to the field of forestry, and in particular relates to a method for inhibiting the growth of poplar stumps. Background technique [0002] With the development of social economy and the needs of ecological environment construction and greening, a large number of ultra-high-speed growing tree species such as poplar are currently planted in the whole province. When these trees are planted in the transmission line channel, it will seriously affect the safe operation of the line. For example, trees often touch high-voltage lines in strong storm weather, causing accidents such as high-voltage line grounding, solitary short-circuit, disconnection and power outage. If trees are planted in violation of regulations in the power facility protection area blindly, so that the trees touch the power line when they grow up, causing short circuit between phases of the line, causing disconnection and tripping, and even causing personal electric sh...
