Description
[technical field]
The present invention relates to ecological environmental protection and Treatment process field, particularly a kind of water-fast wet seeds repair the implantation methods of reservoir drawdown band.
[background technology]
Falling zone is river, lake, the distinctive a kind of phenomenon of reservoir, refers to the region of rising that disappears formed between maximum water level and lowest water level line that reservoir rises because seasonal water level disappears, periodicity retaining and ecological water scheduling etc. cause.Falling zone is naked state, and wash in a pan erosion by rainwater erosion and wave and act on, the soil body is peeled off layer by layer, and severe water and soil erosion even avalanche occurs, and causes reservoir sediment accumulation, destroys two sides natural landscape, accelerates the deterioration of whole ecological environment of reservoir areas.
Afforestation not only can beautify Reservoir region environment, in prevention soil and water loss etc. is ecological, also play very important effect, but reasonably afforestation technology and measure, the key that success or not repaired by reservoir drawdown band will be become.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, provide the implantation methods that a kind of water-fast wet seeds repair reservoir drawdown band, can conserve water and soil by the method, water conservation, to beautify the environment, there is higher environment, Social and economic benef@.
For solving the problems of the technologies described above, present invention employs following technical proposals:
Compared with prior art, the invention has the beneficial effects as follows: the reparation seeds that the present invention filters out good stability by experiment, water-fast wet seeds that diseases and insect pests resistance is strong recover as reservoir drawdown band, bid section is divided to implement in conjunction with falling zone feature, utilize rational afforestation technology and method for planting, reach the object reducing water and soil loss, repair falling zone ecotope, beautify view, there is higher environmental benefit, Social benefit and economic benefit.
[specific embodiment]
In order to make object of the present invention, technical scheme and advantage clearly understand, below embodiment the present invention is described further.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment 1:
Select typical falling zone to carry out at Heyuan City of Guangdong Province Xinfengjiang Reservoir and repair demonstration.Water-fast wet seeds repair an implantation methods for reservoir drawdown band, and its concrete steps are as follows:
1, the choosing of plant
According to species grow habit and wetland natural environmental condition, select annual to there is good stability, reparation seeds that water-fast wet seeds that diseases and insect pests resistance is strong recover as reservoir drawdown band.Metasequoia, yew, Chi Song, swamp cypress, wet-land pine tree, sweetgum, Chinese ash, weeping willow, alder can be had for the water-fast wet seeds chosen.
2, implantation time
After selecting annual draining in summer water level drop to minimum, falling zone complete exposed time plantation.

2, spot soil preparation specification is 100cm × 100cm × 15cm, and afforestation cave specification is 70cm × 70cm × 40cm.
4, method for planting
Below reservoir drawdown band designed elevation waterline, 3 meters is the more superior location of afforestation to designed elevation waterline, is a kind of land resources developed, and adopts water-fast wet seeds to repair seeds, point bid section design and construction for afforestation.
4.1 below designed elevation waterline 0-1 rice bid section, choose wet-land pine tree, water-fast wet seeds that Chinese ash, weeping willow, alder, metasequoia, yew, Chi Song plant as this location.The naked water-fast wet seeds that treetop after planting exceeds designed elevation waterline are put into tree well, back-filling in layers table soil and fine earth, and reality is struck in layering, conscientiously accomplish that root relaxes, Miao Zhi, hilling to rhizosphere portion slightly becomes steamed bun shape with fixing tree root.Wherein, need mix after mud dips in root with phosphate fertilizer when fine day is planted, then root is put into tree well.Especially, after planting, treetop must exceed designed elevation waterline, otherwise afforestation is difficult to successfully.
4.2 below designed elevation waterline 1-2 rice bid section, choose the water-fast wet seeds that metasequoia, yew, Chi Song, swamp cypress and alder are planted as this location.Often spread manuer in holes fused calcium magnesium phosphate 0.2kg mixing thoroughly with soil in cave, the height of tree is greater than 2m, the diameter of a cross-section of a tree trunk 1.3 meters above the ground is greater than 2cm and the water-fast wet seeds of root band soil ball put into tree well, soil more than bulb diameter 30cm, removes the native ball wrappage that can not degrade, vertical trees, first backfill table soil, fine earth, insert the space under real native ball with waddy, back-filling in layers table soil and fine earth, and reality is struck in layering, earthing height is unearthed ball 15cm, and planting, it is once permeable to water in latter 24 hours.
4.3 below designed elevation waterline 2-3 rice bid section, choose the water-fast wet seeds that metasequoia, yew, Chi Song and swamp cypress are planted as this location.Often spread manuer in holes fused calcium magnesium phosphate 0.2kg mixing thoroughly with soil in cave, the height of tree is greater than 3m, the diameter of a cross-section of a tree trunk 1.3 meters above the ground is greater than 3cm and the water-fast wet seeds of root band soil ball put into tree well, soil more than bulb diameter 40cm, removes the native ball wrappage that can not degrade, vertical trees, first backfill table soil, fine earth, insert the space under real native ball with waddy, back-filling in layers table soil and fine earth, and reality is struck in layering, earthing height is unearthed ball 15cm, and planting, it is once permeable to water in latter 24 hours.
5, rear maintenance is planted
After transplanting, young growth will carry out fostering in time and in good time, and strengthen rich water quality management, Juvenile Stage must have enough nutrient supplies, rationally loosens the soil, weeding, accelerates its growth potential and year increment.The construction that children middle forest excavates in the fostering of part forest individuality, the expansion afforestation of falling zone, woods navigation channel of travelling will accomplish that three is synchronous, to reduce afforestation, waterway construction expense, improve and optimize reservoir area tourist resources, containment water and soil loss, increase bio-diversity, thus reach the ecological safety of reservoir area.
During planting rear 1-2, on the hot summer days, drought-resistant water-preserving is carried out to plant, after flood or after the flood discharge of reservoir area, remove residual pollutant and floating thing, in time after-culture is carried out, timely prevention and elimination of disease and pests to plant that is dead and avalanche location.
Through above-mentioned recovery project, the water and soil loss problem of this reservoir drawdown band obtains effective control, reservoir surrounding enviroment obtain beautifies, improve urban area circumstance, facilitate tourism development, create good investment environment simultaneously, there are good social benefit and ecological benefits, especially for the improvement of falling zone, city, view reparation supply a pattern and reference.
