Description
Technical field
The invention belongs to ecological environment field of engineering technology, specifically, it is related to a kind of Subalpine region arid area Artificial grass
Ground planting and establishing method.
Background technology
Drought and water shortage is the great difficult problem for restricting drought-hit area Development of farming and animal husbandry.Collect rain, retaining and reduce echard evaporation etc.
It is the important channel for promoting China's drought-hit area Development of farming and animal husbandry.Subalpine region dry valley（REGIONALIZATION OF THE HENGDUAN MOUNTAINOUS REGION is xeothermic and dry-warm valley）Extensively
Southwestern China area is distributed in, is generally main climatic characteristics with arid, low temperature and Windy Days, but in recent years due to artificial dry
Disturb, for example：Overgraze with large-scale hydroelectric project feeding, cause in region vegetation degeneration to accelerate, serious threatening area peasants and herdsmen
Life and ecological safety.The natural conditions in the region are severe, and ecological environment is extremely fragile, and vegetation is once destroyed, and recover
Difficulty is very big.It is well known that the core recovered to degraded ecosystem is revegetation, revegetation can make full use of soil-
Plant hybrid system function improves local ecological environment, promotes the multifarious formation of living species, soil texture and its physics and chemistry
Matter is recovered, and vegetation succession is reached the stabilization sub stage.Artificial pasture planting is to promote vegetation to recover and alleviate rapidly grass-poultry contradiction
One of effective way, advantage can be provided for the reparation of degraded ecosystem, at the same can with the holding area ecological balance,
Effectively prevent erosion, promote the sustainable development of region social economy.Usual ground mulching regulates and controls skill as a kind of soil
Art, can not only improve WUEL, promote soil moisture rise, play a part of water-retaining effect, and can improve soil
The effect such as earth physical behavior and raising soil microbial activities, and soil erosion, soil protection structure can be reduced, it is crop
Growth provides the conditions such as suitable water, fertilizer and heat, so as to improve crop yield.Arid biogeographic zone crop water conservation technology conventional at present with
Based on irrigation, film covering and improving straw mulching, it has the following disadvantages：Irrigation cost is high, and it is big that water source obtains difficulty.Due to high mountain
Regional Windy Days are more, and film covering difficulty is big, is easily blown away, strong additionally, due to ultraviolet, and day and night temperature is big, and mulch film is decomposed
Speed is fast.And stalk is the important feed of passing the winter of cattle and sheep, peasants and herdsmen are reluctant to as other purposes, and cost is higher, are often drawn
Machine needs 700 yuan.
The content of the invention
In order to solve the above technical problems, the present invention for Subalpine region arid biogeographic zone film covering difficulty is big and improving straw mulching into
The problem of this is high there is provided a kind of low cost, high efficiency and Subalpine region arid area artificial pasture planting and establishing method easy to operate,
This method is simple, and cost is low, easy popularization, can obtain preferable ecological environment benefit.
The present invention is realized by following technical proposal：A kind of Subalpine region arid area artificial pasture planting and establishing method, including with
Lower step：
（1）The primary topsoil of Subalpine region arid area is peeled off, it is thick to be filled to 30~50cm as backfill table soil；
（2）In step（1）Backfill table soil in put the thick gravel layers of 10cm；
（3）Grass seeds is routinely sowed, base fertilizer applies composite fertilizer, then cover the thick primary topsoils of 1~2cm, it is ensured that seed is with soil
Earth is fully contacted, and disposably pours permeable, is watered once within every 2 days afterwards, until seed sprouting, that is, complete Subalpine region arid area people
Work grassland establishment.
The step（1）Primary topsoil refers to remove the soil between top layer and illuvium after humic mulch cover mulch-covering
Earth.
The step（2）Gravel layer be placed to backfill table soil surface, middle part or bottom.
The step（2）The particle diameter of gravel layer cobble-stone is 5~10cm.
The step（3）The amount of sowing of grass seeds is 20~40gm-2。
The step（3）Composite fertilizer's amount of application is 20~40gm-2。
Compared with prior art, the present invention possesses following technique effect：
The Subalpine region arid area artificial pasture planting and establishing method that the present invention is provided, the gravel of selection alpine region rich content is original
Material, is placed in artificial pasture soil, and on the one hand clod cover earth's surface can increase soil infiltration power, another aspect gravel
Stop soil steam outwards to spread, reduce surface soil moisture loss amount；Clod cover can be infiltrated by moisturizing
Measure and suppress moisture evaporation and retain and conserve soil moisture.And clod cover can reduce the water evaporation quantity that wind is brought, soil can be significantly improved
Earth water content, so as to promote plant growth.In addition, gravel surface has a fixed gap, can abundant water conservation, gravel layer can show
Write the growth for promoting artificial pasture on the ground with root system；The grass seeds amount of sowing, mainly by the germination percentage of Elymus nutans, natural environment and
Depending on germination condition, the application rate of the invention limited is moderate, density is reasonable, be conducive to individual plants stalwartness growth；Application rate mistake
Greatly, emerge densification, not only cause the waste of grass seeds, can also increase to light, moisture and the competition of nutrition, make the thin and weak growth of seedling not
It is good, easily attacked by disease；Application rate is too small, density is low, the artificial pasture group planting successful time will be delayed；Present invention limit
Fixed composite fertilizer's amount of application is applied to that development degree is relatively low and the barren Subalpine region Soils In The Region of soil property.The method of the present invention is implemented
After treat that seed sprouting can no longer carry out irrigation and water.The present invention can be widely applied to Subalpine region arid area artificial pasture
During planting, vital effect is played to the ecological environment for improving western alpine region.This method is simple, cost is low,
Easily promote, preferable ecological environment benefit can be obtained.
