Embodiment 1

[0030] In order to investigate the inhibitory effect of inhibitor application methods on the growth of poplar saplings, an inhibitor spraying test was carried out. The test site of this experiment was selected at the nursery base of Nanjing Forestry University in Zhenjiang. The age of the poplar trees in the test site was 2 years old, and the planting density was 40cm×40cm. Three inhibitors were selected, namely glyphosate, paclobutrazol and hexazinone. The treatment level of each inhibitor is designed as follows: glyphosate, 300mg L -1 , 500mg·L -1 , 700mg·L -1 ; Paclobutrazol, 400mg L -1 , 600mg·L -1 , 800mg·L -1 ; Hexazinone, 200mg L -1 , 400mg·L -1 , 600mg·L -1 ; 0 (control).

[0031] The experiment adopts completely randomized block design, and each treatment is repeated 3 times, including 30 (3×3×3+3) test plots in total, with an area of ​​about 100cm×80cm, including 6 to 8 poplar trees, such as figure 1 shown. The application rate of the inhibitor was 1 lite...

Embodiment 2

[0049] The test site of this experiment was selected at the nursery base of Nanjing Forestry University in Zhenjiang. The age of the poplar forest in the test site was 1 year, and the planting density was 40cm×40cm. Annual poplar saplings have underdeveloped leaf crowns and a small receiving surface area, so the method of soil application is adopted.

[0050] According to the results of the aforementioned tree stump test, three inhibitors were selected, namely glyphosate, paclobutrazol and hexazinone. The treatment levels of each inhibitor were designed as low, medium and high levels, respectively: glyphosate, 300mg L -1 , 500mg·L -1 , 700mg·L -1 ; Paclobutrazol, 400mg L -1 , 600mg·L -1 , 800mg·L -1 ; Hexazinone, 200mg L -1 , 400mg·L -1 , 600mg·L -1 ; 0 (control). The experiment adopts completely randomized block design, and each treatment is repeated 3 times, including a total of 30 (3×3×3+3) experimental plots. The plot area is about 100cm×80cm, including 6-8 popl...

Abstract

The invention discloses a method for inhibiting growth of poplar seedlings under a power transmission line. According to the method, an inhibitor is applied to the poplar seedlings at a germination stage of the poplar seedlings in spring each year, the application amount is 830 L per mu, and the concentration of the inhibitor is 300-800 mg per liter. Compared with the prior art, the method has theadvantages that soil application or spraying of hexazinone causes death of the poplar seedlings without manual cutting, a lot of manpower and material resources are saved, the cost for maintenance ofthe power transmission line is reduced, and social contradictions caused by sawing of trees are reduced; soil application or spraying of glyphosate and spraying of paclobutrazol can inhibit the fastgrowth of the poplar seedlings, the cutting frequency is reduced, and the manpower and material resources are saved.

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 seedlings under power transmission lines. Background technique [0002] With the development of social economy and the needs of ecological environment construction and greening, a large number of super-high-speed growing tree species such as poplar are 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 stormy weather, causing accidents such as grounding of high-voltage lines, solitary light short circuits, and power outages. If trees are planted blindly in the protection area of ​​electric power facilities in violation of regulations, the trees will touch the power lines when they grow up, causing short circuits between lines, disconnection trips, and even personal electric shock c...
