Description
Technical field
The present invention relates to ecological control techniques field, more particularly, to a kind of side that manually understory species are quickly rebuild
Method.
Background technology
Desertification of land, alkalization, desertification are one of main problem that current China's ecosystem faces, and China's ecology
The emphasis and difficult point of improvement.In recent years, since Nature and Man is factor destruction, China still remains substantial amounts of deserted mountain barren hill barren beach
Ground, the barren arid of these Soils In The Regions, vegetation sparse, ground mulching deficiency, severe water and soil erosion, environmental degradation, causes area
Property plant be destroyed, the development of ecological key element enters vicious circle, and systemic-function persistently reduces.China is geographical vast, and geographical conditions are multiple
Miscellaneous, there is different zonal vegetation types in Different climate region, this also brings for Vegetation Restoration of Degraded Ecosystem with reconstruction
Extreme difficulties.The technical measures of ecological environment treatment have engineering measure, tillage control measure and biological control measure both at home and abroad at present, its
In, one of the major measure of artificial afforestration as biological treating, in depositing dust noise abatement, carbon fixation and oxygen release, beautifies the environment and adjusts micro-
Environment miniclimate etc. plays positive effect, but there is also it is certain the problem of, such as put undue emphasis on afforestation, ignore understory species
The scientific method of planting, causing artificial forest to possess, efficiency is low, and ecological functions play deficiency, particularly afforest initial stage, and standing forest is single,
System stability is poor, and understory species have not yet been formed, and a large amount of soil exacerbate water and soil stream to a certain extent with the loss of surface runoff
Lose, cause new environmental problem.
Publication number CN102696380A discloses a kind of method that herbage is interplanted in the orchard of Karst Rocky Desertification Region, leads to
The mixed seeding that pulse family and graminous pasture are carried out under fruit tree is crossed, so as to improve vegetation cover rate.Wherein, selected planting grass seeds
The alfalfa belonged to for the halymenia dentata that grass family halymenia dentata belongs to pulse family clover, but chicken feet grass seed is small and light, mass of 1000 kernel is only
1g or so, far below the 3-4g of meadow brome, and the grass seeds happiness temperature it is hygrophilous, it is acidproof, not alkaline-resisting, be primarily adapted for southern high mountain,
Plateau and the middle and lower reach of Yangtze River one are with plantation, day and night temperature major region undergrowth, and the northern area of China generally cold drying, daytime
The night temperature difference is big, and soil depletion arid, is mostly alkaline soil, therefore, which is not suitable in the revegetation of northern China afforested area
Middle large area plantation.
Publication number CN103053242A discloses a kind of method with stereo circulating plantation Desert Control, using tall, filling, grass
With reference to solid growth increase vegetation coverage, wherein grass seeds selects radix glycyrrhizae or clover unicast.But clover unicast is in grass seeds
Degeneration-resistant, emergence is in inferior position into level ground, earth's surface extension, vegetative coverage and water and soil conservation etc., and large area unicast clover is held
Easily because parasitic and pest and disease damage problem occur in the reasons such as illumination, ventilation, crop smothering, risk and cost are managed and protected in increase later stage meadow；It is and sweet
Grass belongs to Chinese medicine, and main application site is under ground portion, though there is certain economic benefit, a large amount of underground biomass excavations are easily
Thin solum is destroyed, surface vegetation is damaged, causes serious erosion of soil and water, lose more than gain.
The content of the invention
In view of the problems of the existing technology, the present invention provides a kind of method that manually understory species are quickly rebuild, and passes through
Hayashishita grassland establishment is carried out after artificial afforestration, to solve during artificial afforestration because excavating, stacking, fill soil and fortune
It is defeated, roll and remove etc. caused by construction that hayashishita earth's surface is exposed with weeds and the problems such as Topographic factor.
The technical solution adopted by the present invention is as follows：
A kind of method that manually understory species are quickly rebuild, comprises the following steps：
1) after artificial afforestration, hayashishita soil is turned over, diameter is removed and is more than remaining woody plant in 5cm stones and soil
Thing root system, levels land；
2) sowed by the way of making between interlacing, it is meadow brome and alfalfa to sow son, both weight ratios
For 1.5-2:1, total application rate is 4.5-6kg/ mus；
3) irrigate to ground moistening degree and reach more than 20cm.
In above-mentioned technical proposal, grass seed selection is one ring of key of revegetation success or failure under artificial forest.Under normal circumstances, people
Work is afforested initial stage, canopy density wretched insufficiency, and during the afforestation such as soil excavation, migration, backfill and prepartion of land,
Superficial layer soil disturbance is violent, and original soil texture and surface vegetation are destroyed, and easily form exposed earth's surface and serious water
Soil be lost in, meanwhile, the barren arid of afforested land general soil, bad environments, and if artificial afforestration select the quick growing species of trees, seedling
Canopy density increases very fast after wood plantation, and hayashishita space is formed and is shaded, and influences the normal raw of planting grass seeds to a certain extent
It is long.Therefore, selection grass seeds needs drought resisting, impoverishment tolerant, sprouting is fast, seedling stage is short, extended capability is strong, and has certain shade tolerance,
Meanwhile underground root system network system can be quickly formed after grassland establishment, culture fertility, strengthens forest land water and soil conservation ability.Grass
Groundbird Wheat Seeds diameter and mass of 1000 kernel are big, and idiosome nutrient content is more, can be sprouted for the seed in barren drought environment and provide abundance
Nutrient, grass seeds emergence lamina is early, and leaf amount is big, and seedling stage is short, and growth of seedling speed is fast, in a short time aboveground vegetation can short-term training level ground soon,
Effective ground mulching is formed, meanwhile, plant tillering ability is strong, and underground rhizome enriches, and can quickly form root system network system, Gu
Soil soil moisture conservation, strengthens soil anti-erodibility by water.In addition, alfalfa belongs to taproot type grass seeds, root system is deep, can make full use of underground

In above-mentioned technical proposal, depth of planting has a great influence grassland establishment effect with thickness of earth covering, after planting quickly goes out
Seedling can reduce energy expenditure when grass seeds is sprouted, and contribute to seedling stage seedling fast-growth, therefore, after planting need shallow earthing 1-
2cm, it is ensured that grass seeds covers.In addition, seedling stage seedling drought-resistant ability is relatively weak, at this time soil drought seedling is injured compared with
Greatly, especially grass family grass seeds, Seedling root is shallow, is more easy to be damaged, and soil moisture generally increases and increases with depth of soil, because
This, suitably seed deeplys and is conducive to seedling and draws more juicy, increase drought resistance；But alfalfa belongs to system of taproot grass seeds, grass seeds goes out
After seedling root system can quickly lower be pricked, so, appropriate upper seeding does not influence the drought resistance of alfalfa not only, and it is quick to additionally aid grass seeds
Emergence forms normal plant.
Preferably, in step 3) in grass seeds growth course, 20% with blade it is withered and yellow when irrigated again.Blade is withered
Huang explanation water shortage is serious to reach more than 20cm, it is necessary to irrigate again to ground moistening depth.
