Summary of the invention
The technical problem to be solved in the present invention is the defect and the deficiency that overcome existing forest instruction plant ecological control, the ecological control method of a kind of south China forest noxious plant is provided, can efficiently control multiple instruction plant simultaneously, rebuild and recover lower subtropical evergreen broad-leaved, the control of putting things right once and for all also finally eliminates instruction plant.Be used in the control of instruction plant and the recovery of forest community in the forest community of instruction plant harm.
The object of this invention is to provide a kind of ecological control method of forest noxious plant.
Another object of the present invention is to provide the application of described ecological control method in the noxious plant control and revegetation of forest.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
An ecological control method for forest noxious plant, step is as follows:
S1. withered shrub and instruction plant is removed;
S2. revegetation: removing on the ground after instruction plant, plantation have the local tree species heavy curtain umbrella maple of the plant ability that resists an invasion, olive, Piao Shu, radix fici simplicissimae, Ivy Tree Bark, exhibition hair with a smile, chinquapin, cloudy fragrant or purling withered in several;
S3. final-period management: after revegetation, removes the revegetation sapling that do not survive in time and reseeds.(in order to better revegetation effect, can also early stage after revegetation, regularly or irregularly remove noxious plant, spray low-toxin farm chemicals and suppress undesired plant growth.)
Above-mentioned noxious plant refers to the instruction plant of positive natural disposition or local indigenous disaster plant.
The instruction plant of described positive natural disposition refers to the draft of positive natural disposition, liana or shrub instruction plant.
Preferably, described noxious plant refer to lantana (
lantana camaralinn.), spend in vain beggar-ticks (
herba Bidentispilosa), Ipomoea cairica (
ipomoea cairica(L.) Sweet), trilobated leaf elegant jessamine (
pueraria lobata(Willd.) Ohwi), mountain pig dish (
merremia umbellate(Linn.) Hall), amplexicaul jasmine leaf (
jasminum elongatum(Bergius) Willd), Jia Betel (
piper samentosumroxb) or roughleaf raspberry root or leaf (
rubus alceaefoliuspoir) one or more in.
More preferably, described noxious plant refers in particular to one or more in trilobated leaf elegant jessamine, mountain pig dish, amplexicaul jasmine leaf, Jia Betel or roughleaf raspberry root or leaf.
The present invention is by large quantifier elimination, exploration and long-term experimental verification, construct the ecological control method of above-mentioned forest noxious plant, especially for the forest that South China is invaded by one or more in trilobated leaf elegant jessamine, mountain pig dish, amplexicaul jasmine leaf, Jia Betel or roughleaf raspberry root or leaf etc., there is the effect controlling and suppress instruction plant very efficiently, plant multiple specific indigenous tree species build and finally recover vegetational type, and once and for all can suppress the outburst again of instruction plant, revegetation efficiency is high.
For machine-processed aspect, inventor thinks it may is that the branches and leaves in great numbers of revegetation have covered sunlight at first, makes the draft of these positive natural disposition, liana or shrub instruction plant to carry out normal photosynthesis and vital movement.But, through large quantifier elimination and exploration, inventor finds, the mechanism of action not only that, because only have plantation local tree species heavy curtain umbrella maple of the present invention, olive, Piao Shu, radix fici simplicissimae, Ivy Tree Bark, exhibition hair with a smile, chinquapin, cloudy fragrant or purling withered in severally just can reach described control noxious plant and the effect of revegetation, more complicated ecological factor and composite factor may be there is in the middle of this, because different floristics, different miscegenation modes or even different plantation spacing, its niche formed all has the difference of essence.Concrete reason and influence factor inventor are also in the middle of studying further and exploring.
In addition, preferably, remove withered shrub and instruction plant described in step S1 can adopt mechanical removal, manually remove or spray low-toxin farm chemicals and remove.
Preferably, the mode of planting described in step S2 is miscegenation equably.
Preferably, described miscegenation be equably by heavy curtain umbrella maple, olive, Piao Shu, radix fici simplicissimae, Ivy Tree Bark, exhibition hair with a smile, chinquapin, cloudy fragrant or purling withered in severally carry out intercropping.
Preferably, the line-spacing of described intercropping is 2 ~ 3m, and spacing in the rows is 2 ~ 3m.
More preferably, often capable plantation 3 ~ 10 saplings of described intercropping.
That is, in a panel region, according to line-spacing 2 ~ 3m, spacing in the rows 2 ~ 3m, often the mode of capable plantation 3 ~ 10 saplings is planted; After having planted, then plant another panel region after the same method, until recovery district to be controlled revegetation completes.
The present invention also can adopt another kind of preferred mode to carry out revegetation, recovery district to be controlled by heavy curtain umbrella maple, olive, Piao Shu, radix fici simplicissimae, Ivy Tree Bark, exhibition hair with a smile, chinquapin, cloudy fragrant or purling withered in severally to upset at random, plant according to the mode of line-spacing 2 ~ 3m, spacing in the rows 2 ~ 3m.
Present invention also offers the application of above-mentioned ecological control method in the noxious plant control and revegetation of forest.Described forest refers to by the forest of one or more invasions in trilobated leaf elegant jessamine, mountain pig dish, amplexicaul jasmine leaf, Jia Betel or roughleaf raspberry root or leaf.
The present invention has following beneficial effect:
The present invention is by large quantifier elimination and exploration, construct a kind of ecological control method of forest noxious plant, first after removing instruction plant, plantation local tree species heavy curtain umbrella maple, olive, Piao Shu, radix fici simplicissimae, Ivy Tree Bark, exhibition hair with a smile, chinquapin, cloudy fragrant or purling withered in several, effectively can control the draft of the positive natural disposition of one or more mixing, liana or shrub instruction plant simultaneously, and prevent the intrusion of the recurrence of instruction plant and new instruction plant.
Method of the present invention especially for South China by forests of lantana, one or more invasions of spending in vain in beggar-ticks, Ipomoea cairica, trilobated leaf elegant jessamine, mountain pig dish, amplexicaul jasmine leaf, Jia Betel or roughleaf raspberry root or leaf, can disposable while, the efficient and instruction plant that the control of putting things right once and for all is all.
The method once and for all can not only suppress the harm of elimination instruction plant and again breaks out, and vegetation efficiency is high, recover the composition of forest community, forest diversity is high, the economic benefit of revegetation seeds can be realized, to the sustainable development of South China forest and the raising of economic benefit, for reconstruction and Developing Ecological Forest system, there is important and far-reaching meaning.
