Description
Technical field
The present invention relates to a kind of planting and establishing method of artificial pasture, mixed seeding is artificial under especially a kind of Sandy Grassland dry farming
Grassland establishment method.
Background technology
China possesses nearly 400,000,000 hm2 of all kinds of grassland areas, occupies second place of the world, accounts for about the 41.7% of national territorial area.It the whole nation can
It is divided into six prairie areas（Northeast pastoral area, North China pastoral area, oasis in northwest, Qinghai-Tibet pastoral area, southwestern pastoral area, southern pastoral area）, China
North, northwest and the desertification of three ground of Qinghai-Tibet are the most serious, and desertification area accounts for the 43.9% of national desertification land area, and with every
The speed in 2,000,000 hectares of year continues to expand.
Although country increases input in recent years, implements a series of grassland ecologies and administer and protect construction project, grassland
The situation of ecological degeneration is not contained effectively.
It is to increase substantially Sandy Grassland production capacity, alleviate grass poultry at present in Sandy Grassland planting Mixed Pasture
One of contradictory main path.To large-scale developing and utilizing northern China sandy land control, develop husky area, sand ground Animal husbandry production,
It improves the ecological environment and has practical significance.But there are grass seed selections to mix for existing Mixed Pasture build and plant technology
The problems such as random, mix-seed-rate and unreasonable fertilising.
Invention content
The purpose of the present invention is to provide Mixed Pasture planting and establishing method under a kind of Sandy Grassland dry farming, for gram
Above-mentioned technological deficiency is taken, it is difficult, grassland desertification getting worse to solve Mixed Pasture planting under Sandy Grassland dry farming
Problem,
To achieve the above object, Mixed Pasture planting and establishing method under a kind of Sandy Grassland dry farming of present invention offer, in sand
When being sowed under change meadow dry farming, pulse family and grass are subjected to mixed seeding, wherein alfalfa, Medicago ruthenica, Da Wuli
Shrub lespedeza, wheatgrass are 0.8-1.2 with weight ratio:0.8-1.2:1.6-2.4:The ratio of 3.2-4.8 carries out mixed seeding；It is fitted in mixed seeding
Suitable dose is：Urea 250-270kg/hm2, calcium superphosphate 440-460kg/hm2, potassium sulfate 110-130kg/hm2。
Further, the dose suitable in mixed seeding is：Urea 260kg/hm2, calcium superphosphate 450kg/hm2, potassium sulfate
120kg/hm2。
Further, alfalfa, Medicago ruthenica, Lespedeza davurica, wheatgrass with weight ratio be 1:1:2:4 ratio carries out
Mixed seeding.
Compared with prior art, the beneficial effects of the present invention are：The present invention is taken by rational pulse family+grass family
Match, forms alfalfa, Medicago ruthenica, Lespedeza davurica, wheatgrass Mixed Pasture, different types of grassland vegetation is made mutually to tie
It closes, soil fertility can be effectively increased, improve soil property, reduce the desertification degree of Sandy Grassland, improve environmental quality.By in sand
Change planting alfalfa, Medicago ruthenica, Lespedeza davurica, wheatgrass Mixed Pasture under the dry farming of meadow, meadow species
Abundant degree improves 36.2%-47.6%, and density increases 5-9 kinds/m2, biomass improves 34.7%-42.3%, and Grass cover degree carries
High 78%-82%.
Specific implementation mode
The present invention is further explained in the light of specific embodiments.
From the aspect of annidation, wheatgrass, alfalfa, Medicago ruthenica and Lespedeza davurica are that wide width drought life is more
Year raw good forage is distributed and well-grown in provinces and regions such as China northeast, North China, the Inner Mongol, Gansu, Qinghai, Xinjiang, resists
Non-irrigated ability is stronger, can be grown in sandy, the hilly upland of dry steppe, can be used as improvement arid, degenerates or Grassland desertification
Good after-culture material, Sandy Grassland can Quick slicing growth.From the aspect of phenology, wheatgrass turns green morning, be suitble to turn green compared with
The alfalfa in evening, Medicago ruthenica, Lespedeza davurica mixed seeding.From the aspect of vertical structure of community, alfalfa, Medicago ruthenica
Half sprawl growth of cauline leaf covers ground, is suitble to wheatgrass, Lespedeza davurica mixed seeding with middle level or upper layer, is conducive to ecogroup
The stability fallen.
Embodiment one：Ku Buqi sand grounds are located at the about 5km of Ordos of Inner Mongolia Dalate Banner south, are located in Middle Yellow River
