Description
Technical field
The invention belongs to alkaline land improvement technical fields, draw grass more particularly to a kind of strand sandyization salt-soda soil plantation sand
And the method for improvement clay fertilizer situation.
Background technology
At present, alkaline land improvement is mainly the following technical measures：
1st, water conservancy improves, the fresh water desalinization of soil by flooding or leaching：Suitable for the higher well-drained region of topography.
2nd, biological modification：Improve salt-soda soil micro-ecological environment, using bio-organic fertilizer, while supplementing organic matter, increase
Add soil beneficial microorganism quantity, make to establish new microecological balance between alkaline land soil, plant and microorganism, reach raw
The target of object control.
3rd, chemical modifying：Per hectare applies 15 tons or so of gypsum, makees base manure and once applies, and can also combine local practical arable land
In the conditioned soil of alkaline spot and grassland alkaline spot.
4th, ground is ploughed deeply, at least to descend to dig 70 centimeters or more, continuously plough deeply 2 years to 3 years, it is general when could solve to pour substantially
The problem of alkali.
5th, soil moved in improve the original is improved：In weight alkaline spot plot, alkaline spot is dug into depth 40cm, backfilling new soil.
But each of the above method all there is it is more or less the shortcomings that, each method be used alone when it is basic
On be all palliative, be also usually that one of them small aspect is taken to carry out part improvement in the prior art；So it needs
A kind of effective comprehensive processing method of science improves salt-soda soil, fundamentally improves salt-soda soil, then utilizes improvement
Corresponding industrial crops are planted in salt-soda soil afterwards, maintain and improve improved effect and bring economic benefit.
Sand draws careless alias for purple red grass, Siberia Zi Dan, and Boraginaceae purple is red to belong to perennial herb.Sand draws careless main distribution
In Coastal Sandy Land, this kind of plant has elongated root-like stock, crawls or oblique ascension, horizontal rhizomes are distributed in 15~20 under table soil more
Centimeters, vertical root can be distributed to 1 meter or so depths, and mainly carry out vegetative propagation by means of the extension of root-like stock, belong to medium
Relatively low or medium forage plant.Flower gives off a strong fragrance, and can extract its aromatic oil, can also make green manure.Sand draws grass or one kind secretes salt
Plant, preserving the ecological environment, aspect plays irreplaceable role, such as promotees silt, Bao Tan, shore protection to resist sea water intrusion, with
And it fixes the sand, is windproof, sand prevention and control effect；So draw grass by planting sand treated that strand sandyization salt-soda soil can be gradually
The base of other crops can be planted by improving into.
By the way that different ameliorative measures is combined, corresponding plant is planted in cooperation, can be rapidly in varieties in saline-alkali areas shape
Into vegetation, then by artificial and natural adjusting process, it is most effective approach that improvement is carried out to the soil in salt-soda soil.
Invention content
The technical problems to be solved by the invention are：A kind of strand sandyization salt-soda soil plantation sand is provided and draws grass and conditioned soil
The method of fertile situation.This method can effectively improve strand sandyization salt-soda soil, and the sand of plantation draws careless survival rate height, yield
Height has significant economic, society and ecological benefits.
In order to solve the above technical problems, the technical scheme is that：
The method that strand sandyization salt-soda soil plantation sand draws grass and improvement clay fertilizer situation, includes the following steps：

Mu applies 2000~3000 kilograms of the sandy alkaline land improving compound fertilizer in strand, after ploughing deeply with harrowing, then ground is raked, trench digging pours
Water, in case sowing；
B. seed treatment：Presoaking and germinating is carried out before sowing, is first rinsed 2 times with clear water, to remove the impurity in seed；Again will
Seed after flushing, which is immersed in the cold water of room temperature, to be impregnated 12 hours, so that seed fully absorbs moisture, is positioned over after water is filtered
Shady place prepares sowing；
C. it sows：The processed seed of vernalization is uniformly sprinkling upon the ditch for pouring water in ridge face by annual late March to early April
It is interior, the thin soil of 1~2 cm thick is covered on seed, sowing quantity is 15 kilograms of per hectare；
D. field management：Including pouring water and top dressing；Although sand draws grass for mesoxerophytes, drought resistance is stronger, and arid is
Pay attention to pouring water；Growth period top dressing twice, before florescence late May and late July fruit maturation before supplement composite fertilizer and
Potash fertilizer；

By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
To draw the measures such as grass sandy to improve strand using strand sandy alkaline land improving compound fertilizer and plantation sand by the present invention
Change salt-soda soil；Wherein 1) compound water retaining agent can preferable moisture absorption and moisture releasing；Sandy soil binding agent can improve soil physical property, increase
The water conservation soil conservation ability of strong soil；Citric acid mainly neutralizes the alkali in salt-soda soil to its acidity, reduces soil pH value.
2) attapulgite clay has the characteristics that cohesive force is strong, adsorption capacity is big, and sand effectively can be bonded,
And it is supplied to micro elements by plants.
3) organic matter decomposition is fast, accumulative fewer in salinization of soil sand, thus causes soil fertilizer poor,
Various nutrients are all poorer, and the nutrient formed by fulvic acid, organic fertilizer through microorganism decomposition simultaneously lasting rapidly can carry
Soil nutrient is supplied, and soil pH value is reduced by producing the metal ion in acid, degradation or conversion soil, changes soil knot
Structure has protected plant nutrient equilibrium, and supplement crop nutrition content promotes root system development, so as to improve the yield of crops, reduces farmland
Cost achievees the purpose that increase farmers' income.
4) nitrogen-fixing bacteria in micro organism powder and arbuscular mycorrhizal fungus can itself fixed nitrogen or with plant cooperated fixed nitrogen；Thermophilic salt
Metal ion supply plant in basophilic bacterium conversion nature utilizes；Bacillus, lactobacillus delbrueckii trichodermaharzianum and aspergillus
It is mainly used for organic matter of degrading, and cooperates with the resistance for increasing plant.
5) desulfurated plaster can effectively improve salt affected soil, and the sodium ion in soil is handed over the calcium ion that gypsum dissolution generates
It changes, supplement calcium ion can eliminate toxic action of the carbonate to plant, reduce the basicity of soil, adjust the pH value of soil, carry
The dispersibility of high soil sticking grain, makes soil water permeability improve, while also containing the necessary sulphur of plant growth, silicon etc. in desulfurated plaster
Mineral element, useful crop plants growth.
6) expanded vermiculite can preferably adsorb main micro organism powder, ensure the content of microorganism in fertilizer, and also rise
To the effect for improving soil texture.
7) it is a kind of salt-secreting plant that sand, which draws grass, and preserving the ecological environment, aspect plays irreplaceable role, has and promotees
To resist sea water intrusion and fix the sand, windproof, sand prevention and control effect, the cooperation sandy salt-soda soil in strand changes for silt, Bao Tan, shore protection
Good organic and inorganic element and microorganism in compound fertilizer can do physics, chemistry and biology side to sandy alkaline land soil
The multi-faceted improvement in face.Feed and green manure are also used as to use.
Therefore, the measures such as grass are drawn using strand sandy alkaline land improving compound fertilizer and plantation sand to improve salt-soda soil, sand
The survival rate and yield for drawing grass are significantly improved, and the improved effect in entire salt-soda soil are protruded, the environmentally protective nothing of improved, process
Pollution.Therefore it is a kind of application technology for being worth being widely applied.
