Description
Technical field
The invention belongs to field of forestry, and in particular to the inhibition growing method of poplar seedlings under a kind of transmission line of electricity.
Background technique
With the development and improvement of the ecological environment of social economy and the needs of greening, poplar is largely planted across the entire province at present
The superelevation quick growing species of trees such as tree.When these trees are planted in electric transmission line channel, the safe operation of route can be seriously affected.Example
If treetop usually touches high-voltage line in the weather of tempest, cause the accidents such as high-voltage line ground connection, lonely light short circuit, broken string power failure.
If blindly planting trees in violation of rules and regulations in protection of electric power facility area, so that trees touch power circuit after growing up, route phase is caused
Between short circuit, cause broken string trip, or even cause the person electric shock injures and deaths and broken string have a power failure accident, not only cause power supply enterprise by
Very huge economic loss also influences whether user to the normal use of electricity.Both just poplar in channel was cut down, and still could
Again it sprouts, route operation is generated seriously threaten again.It is public that National Power System 35KV and the above transmission line of electricity break through 300,000
In, caused by external force is destroyed in addition to accident, trees stand in the breach to accident caused by wire electrical discharge, need to consume a large amount of people every year
Power, material resources and financial resources.And the indirect economic loss as caused by power-off and social adverse effect are then more huge.
The route run unit of current each power supply company puts into a large amount of human and material resources and carries out channel maintenance, but effect
It is unsatisfactory.Reason is mainly that growth of poplar is fast, and 3 to five years Seedling heights are just up to 28~32 meters, more than under transmission line of electricity
Limit for height.Although cutting down to poplar in electric transmission line channel, it is with very strong rudiment and growth ability, and secondary annual meeting is again
Route operation is generated and is seriously threatened；In addition, damaging and preventing erosion to preserve the ecological environment, reducing forest, country is adopted
Economic lever measure is taken to limit trees felling, i.e. raising trees cut down damages.The implementation of these measures undoubtedly aggravates
The financial burden of power supply enterprise.Moreover, the villager for living in surrounding is also the interests for pursuing oneself, around transmission line of electricity
A large amount of plantation poplars of blindness, for the sudden huge profits for seeking to cut down trees.So when annual spring growth of poplar season arrives, Utilities Electric Co.
To put into a large amount of manpower, financial resources on one side to contain the growing way of poplar under transmission line of electricity, also to be negotiated on one side with villager to avoid
Unnecessary contradiction.The problem of this year year must face has seriously affected the safety and power supply system of power supply line
Normal operation, it would be highly desirable to solve.
Traditionally, the route run unit of each power supply company is mainly by the way of felling, not only to the maintenance of route
A large amount of human and material resources are expended, and effect is undesirable, cannot tackled the problem at its root.For example, 2006 to Nanjing Pukou
Poplar in area Millennium forest farm is removed obstacles, and more than 7,000,000 yuan of cost.Even if but cut down poplar, still it can sprout again
Hair, highest growing height will again generate route operation up to more than 20 rice and seriously threaten, " tree line contradiction " has become influence
An important factor for line security is run.Electric transmission line channel after how cutting down to the superelevation quick growing species of trees such as poplar is tieed up
Shield ensures, is a difficult problem to lie across in face of online road transport administrative staff.
