Description
Technical field
The present invention relates to agricultural technology field, particularly a kind of for greenhouse by solar heat salinization soil press down salt structure.
Background technology
Because greenhouse by solar heat cropping index is high, vegetable grower, for pursuing high yield and blindly excessive fertilization, easily causes soil salinity accumulation.Inside greenhouse environment is airtight, and soil plough horizon salinity is difficult to by rain drop erosion, and the hot conditions of inside greenhouse impels soil water evaporation strong simultaneously, causes salinity with soil capillary water moving and assembling at soil table, very easily causes soil secondary salinization.The hyperosmosis that too high salinity produces hinders plant roots to the absorption of soil capillary water, affect the osmotic adjustment of crop, cause tissue damage, plant nutrient is hindered to absorb and normal growth, suppress soil microbial activities, and causing crops Severe Reduction, the soil salinization is the major issue faced in Installation Vegetable Cultivation process, seriously governs the sustainable development of China's facilities vegetable industry.
The improvement method of current people to greenhouse by solar heat saline soil mainly contains physical method, chemical method, engineering method and the technological means such as biological prosthetic.Wherein the large hydraulic pressure salt of the many employings of physical method, intertillage are loosened the soil; Adopt the chemical methodes such as gypsuming, although salination can be alleviated in a short time, too increase Ca in soil simultaneously
2+content, easily cause Ca
2+excess accumulation, increase the weight of the soil salinization; The human and material resources that the water engineering facility consumption such as application hidden pipe salt discharge are a large amount of, are difficult to spread.Therefore, according to soil in protected field salt accumulation feature, explore a kind of suitable ameliorative measure very necessary.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides one and the following soil salt of greenhouse by solar heat topsoil can be suppressed to migrate to topsoil soils, and that can play the salinization soil of preserve moisture and fertility effect presses down salt structure simultaneously.
The present invention is achieved through the following technical solutions:
A kind of for greenhouse by solar heat salinization soil press down salt structure, it is characterized in that: comprise the vertical interlayer being positioned at surrounding, the horizontal interlayer being positioned at underground, and be covered in ground ground upper caldding layer, the degree of depth being positioned at underground of described vertical interlayer is 30-40cm, and the 3-5cm that is above the ground level, described horizontal interlayer is positioned at the below of vertical interlayer.
Described vertical interlayer is made up of PE film and straw mat, and PE film is outside straw mat, planting area entirety in greenhouse by solar heat is crowded around by vertical interlayer, PE film is in the outside of straw mat, can according to the type of long-term cropping and feature, to crowd around the vertical interlayer in region and be divided into some pieces, all there is straw mat the PE film both sides of crowding around in region.
Described horizontal interlayer is made up of organic materials, and as stalk, bacterium slag etc., thickness is 10-15cm.
Upper caldding layer bottom, described ground is the organic matter bed of material, and organic matter bed of material top covers black mulch film, is laid on the furrow of field.
The invention has the beneficial effects as follows: of the present invention is that solid is arranged every salt preserve moisture and fertility structure, horizontal interlayer and vertical interlayer can effectively stop the following soil salt of topsoil on move and ooze with the side of horizontal adjacent soil, it is up that black mulch film effectively can reduce soil table temperature minimizing water salt, this stereochemical structure effectively can improve greenhouse by solar heat water and fertilizer utilization and every salt efficiency, structure is simple, can apply in a flexible way according to concrete plantation situation simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is plan structure schematic diagram of the present invention;
Accompanying drawing 2 is cross-sectional view of the present invention;
In figure, 1 straw mat, 2 PE films, 3 planting areas, 4 black mulch films, 5 vertical interlayers, 6 horizontal interlayers, 7 ground upper caldding layers, 8 soil plough horizons, the 9 organic matter bed of materials.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.Should for greenhouse by solar heat salinization soil press down salt structure, comprise the vertical interlayer 5 being positioned at surrounding, be positioned at the horizontal interlayer 6 of underground, and be covered in ground ground upper caldding layer 7, the degree of depth being positioned at underground of described vertical interlayer 5 is 30-40cm, and the 3-5cm that is above the ground level, vertical interlayer 5 is made up of PE film 2 and straw mat 1, and PE film 2 is outside straw mat 1, planting area 3 entirety in greenhouse by solar heat is crowded around by vertical interlayer 5, PE film 2 is in the outside of straw mat 1, can according to the type of long-term cropping and feature, the vertical interlayer 5 in region will be crowded around and be divided into some pieces, described horizontal interlayer 6 is positioned at the below of vertical interlayer 5, be made up of organic materials, as stalk, bacterium slag etc., thickness is 10-15cm, all there is straw mat 1 PE film 2 both sides of crowding around in region, upper caldding layer 7 bottom, ground is the organic matter bed of material 9, and the organic matter bed of material 9 top covers black mulch film 4, is laid on the furrow of field.
Of the present invention is that solid is arranged every salt preserve moisture and fertility structure, horizontal interlayer 6 and vertical interlayer 5 can effectively stop the following soil salt of topsoil on move and ooze with the side of horizontal adjacent soil, it is up that black mulch film 4 effectively can reduce soil table temperature minimizing water salt, this stereochemical structure effectively can improve greenhouse by solar heat water and fertilizer utilization and every salt efficiency, structure is simple, can apply in a flexible way according to concrete plantation situation simultaneously.
