Description
Technical field
The present invention relates to technical field of land improvement, and in particular to a kind of synthesis improvement method of sandy land cultivation layer.
Background technology
China is one of country that river, lake are numerous in the world, and person is up to more than 1000 square kilometres for drainage area
More than 1500 bars.River is divided into exorheic river and continental river.The exorheic river of ocean is injected, drainage area accounts for the Chinese land gross area
64%, and often influenceed by severe (heavy rain, heavy rain) weather, effectiveness factors often occur, along the river, sandy soil ground area in area along the lake
Constantly amplification, and water conservation, fertility be not low for sandy land soil, common plant is difficult growth, while sandy land is the important soil in China
A part for ground resource；Therefore, sandy land soil remediation problems demand solves.
The characteristics of sandy land, we can talk from the microstructure of soil, what soil was all made up of small particle,
These particles constitute the porous system of loosing soil, and it is made up of three solid, liquids and gases materials.Soil
Solid matter includes mineral matter and organic matter two parts, and for mineral matter as the skeleton of soil, organic matter seems its muscle bag
Mineral surfaces are rolled in, it is the treasure-house of plant absorption moisture and nutriment.Liquid portion refers to the moisture in soil, it preserve and
Motion is most active part in soil, the gas of soil refers to the air in soil, and it is filled between the space of soil
In those spaces not occupied by moisture.Space in sandy soil is larger, shows preferable permeability, while is also water conservation
Property, water resistance difference major reason.In sandy soil soil, the content of organic matter is fewer, is to cause soil structure loose, leakiness liquid manure
Major reason；
At present, the Treatment process of sandy land soil is mainly transplanted by soil moved in improve the original, application of organic fertilizers and composite fertilizer improve sand
The nutritional ingredient of soil, the pH value of soil, nitrogen, phosphorus, potassium, organic matter, humic acid are changed by the chemical improvement agent of special configuration
Content, improve the physicochemical property of soil.But these modifying agents is complicated, input is high, material resources are few, a large amount of productions have office
It is sex-limited.The program time of nutrients enrichment is grown, can not be integrated, system, large area and healthy and lasting development.
The content of the invention
The technical problem to be solved in the present invention is, in view of the foregoing defects the prior art has, there is provided a kind of sandy land
The synthesis improvement method of layer is cultivated, the active ingredient being effectively improved in sandy soil, reaches the active ingredient ratio that suitable for plant grows,
Permanent benign cycle is formed, realizes that waste develops, safe and environment-friendly, energy-conservation, emission reduction sustainable development.Solve existing change
Good technical sophistication, cost be high, not system, it is unhealthy persistently the problem of shortcoming.
The present invention is that technical scheme is used by solving above-mentioned technical problem：
A kind of synthesis improvement method of sandy land cultivation layer, comprises the following steps：
1) using the biomass carbon soil of doses as modifying agent, mix in sandy soil；
2) mixture will be formed after biomass carbon soil and the uniform mix of sandy soil；
3) its moisture content is made to reach 30%~40% mixture watering；
4) mixture is covered into a period of time with cotton；
5) geomembrane is laid on former sand soil layer；
6) mixture is paved uniformly by certain thickness on geomembrane, forms improvement cultivation layer；
7) improvement cultivation layer on uniformly sow, then with cotton covering and timely water seasoning；
8) it is its sunshade after emerging；
9) treat that seedling length raises cotton to more than 10CM, and do not continue to for its sunshade, allow it to grow naturally.
According to above-mentioned technical proposal, before described step 1), the biomass carbon soil as modifying agent need to spread drying out.
According to above-mentioned technical proposal, in described step 1), silt content is 30% and following sandy soil, the incorporation of modifying agent
Measure as the 5% of sandy soil, sandy soil of the silt content within 30%~60%, the incorporation of modifying agent is the 9% of sandy soil, and silt content exists
60% and the sandy soil of the above, the incorporation of modifying agent is the 13% of sandy soil.
According to above-mentioned technical proposal, in described step 2) after uniform mix, mixture is piled into stack.
According to above-mentioned technical proposal, in described step 4), the time of cotton covering is 2~3 days.
According to above-mentioned technical proposal, in described step 5) and step 6), geomembrane is geotextiles.
According to above-mentioned technical proposal, in described step 7), maintenance of heating up water is specially respectively to pour a water sooner or later.
According to above-mentioned technical proposal, in described step 8), the specific means of sunshade is to prop shading screen or heavy foliage branch.
The invention has the advantages that：
1. the modification method of the present invention, the active ingredient that can be effectively improved in sandy soil, anti-leak-stopping fertilizer, improve original soil
In chemical property, reach suitable for plant growth active ingredient ratio, form permanent benign cycle, by waste develop profit
With, safe and environment-friendly, energy-conservation, emission reduction sustainable development, solve existing improving technology is complicated, cost is high, not system, unhealthy hold
Long the problem of shortcoming.The soil body is reinforced using geomembrane, plays a part of fertilizer conservation, soil moisture conservation.
2. according to the property and content of different sandy soil, the improver special of various dose is mixed；Pass through the change of special configuration
The pH value of modifying agent change soil, nitrogen, phosphorus, potassium, organic matter, the content of humic acid, improve the physicochemical property of soil.

The modifying agent of various dose, silt content are the 5% of soil layer in 30% and following soil layer, the incorporation of modifying agent, and silt content exists
Soil layer within 30%~60%, the incorporation of modifying agent are the 9% of soil layer, and silt content is 60% and the soil layer of the above, improvement
The incorporation of agent is the 13% of soil layer.
Further, mixture is piled into stack after uniform mix in described step 2).
Further, in described step 4), the time of cotton covering is 2~3 days.
Further, in described step 5) and step 6), geomembrane 2 is geotextiles.
Further, in described step 7), maintenance of heating up water is specially respectively to pour a water sooner or later.
Further, in described step 8), the specific means of sunshade is to prop shading screen or heavy foliage branch.
The operation principle of the present invention：
Why the present invention can produce above-mentioned positive effect, be due to containing abundant plant growth in biomass carbon soil
Required chemical element (i.e. organic matter, humic acid, mineral oil, excrement colibacillus group, nitrogen, phosphorus, potassium etc.), under itself drying regime
Multiple-void structure, water-swellable, there is very strong water absorbing capacity, can effectively absorb underground water and diving, rainwater etc.；And have after meeting water
Higher adhesive capacity is effectively combined with sandy soil；The water holding capacity of sandy soil can be improved, reduces the pH value of sandy soil, and effectively supplement is husky
Organic matter, humic acid, nitrogen, phosphorus, potassium equal size in soil.
This modification method, show through field experiment, the active ingredient that can be effectively improved in sandy soil, anti-leak-stopping fertilizer, improve
Chemical property in original soil, reach the active ingredient ratio of suitable for plant growth, form permanent benign cycle.Experiment inspection
Survey is shown in Table 1, table 2, table 3, table 4, Fig. 2.
