Description
Technical field
The present invention relates to a kind of root control salt method using Maifanitum filter layer and plant at salt-soda soil alta fascue
In application, belong to agricultural use technical field.
Background technology
Current China water, soil resource owning amount, only can guarantee that 500,000,000 tons of grain production capacity, can not meet far away population day
The great demand that benefit increases.Meanwhile, China's energy scarcity contradiction is increasingly sharp-pointed, and biomass energy development must ensure " grain
Safety " premise.The Coastal beach of nearly more than 4,000 ten thousand mu of all kinds of gross areas that China has at present is the standby soil that China is important
Ground resource, Coastal beach saline-alkali soil develops and is possible not only to provide food source, also can become the important salt-tolerant plants such as the energy
Production carrier.
At present, in terms of utilizing beach saline-alkali ground developing agricultural plantation, how to control crop root zone and do not gather too
Many salinities, maintaining while topsoil soils salt balance saving water resource and promoting soil fertility and become restriction beach area agricultural
The realistic problem of sustainable development.
For the transformation in salt-soda soil, the mankind have done many significant explorations and research, mainly have following several method: 1,
Chemical amendments, i.e. adds substantial amounts of chemical substance, as Gypsum Fibrosum, ardealite, acidic materials and water-retaining agent etc. are changed to salt-soda soil
Learn, to improve the effective ingredient in salt-soda soil；2, biological method, mainly by plantation alkali resistance plant, manually sets up hay
Layer etc.；3, physical method, main by scarifying soil layer, change the physical arrangement of saline and alkaline layer.
The renovation technique in existing salt-soda soil controls crop root zone do not gather too many salinity and have the disadvantage in that
1, poor to the physicochemical property improved effect of soil in salt-soda soil；
2, in soil, salinity can not control very well in the range of plant suitable growth；
3, the concentration regulating effect of ion each to soil in salt-soda soil is poor；
Maifanitum belongs to volcanic rocks, and its main mine material is volcanic rock.Before 5000 7,550 ten thousand years, the lava that volcanic eruption goes out buries
In underground, through scabland high humidity sweltering heat effect, these lava are changed into acidic materials, by the produced pressure of diastrophism
Effect, ultimately formed Maifanitum.Maifanitum is to biological nontoxic, harmless and have certain bioactive complex mineral or medicine
Use rock.The main chemical compositions of Maifanitum is inorganic aluminosilicate.Including SiO2, Al2O3, Fe2O3, FeO,
MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO etc., possibly together with the whole macroelements needed for animal, such as: K, Na, Ca, Mg,
The trace element such as Cu, Mo and rare earth element, about 58 kinds more than.
Summary of the invention
The present invention solves the deficiency that prior art exists, it is provided that a kind of root control salt method using Maifanitum filter layer
And the application in salt-soda soil alta fascue is planted, to realize following goal of the invention:
(1) the root control salt method that the present invention contains filter layer has good improvement effect to the physicochemical property of soil in salt-soda soil
Really；
(2) salinity in soil can be controlled at long-term cropping suitable growth by the root control salt method that the present invention contains filter layer
In the range of；
(3) the root control salt method that the present invention contains filter layer has good regulating effect to the concentration of ion each in planting site；
(4) to contain the root control salt method of filter layer without any side effects to long-term cropping plant for the present invention, and safety is high.
For solving above technical problem, the technical solution used in the present invention is as follows:
A kind of root control salt method using Maifanitum filter layer, described root control salt method includes laying filter layer step.
The following is and technique scheme is further defined that
Described filter layer, including Maifanitum, Japanese plum wood activated carbon, hazelnut shell activated carbon, flyash.
Described filter layer, in parts by weight, including following components: Maifanitum 45-60 part, Japanese plum wood activated carbon 14-20
Part, hazelnut shell activated carbon 4-7 part, shive cellulose base water-retaining agent 5-8 part, birch leaf 10-15 part, corynebacterium glutamicum
