Detailed Description
As shown in figure 1, a saline and alkaline land arbor planting cave structure, including the cave body that is arranged in saline and alkaline soil layer 1, be equipped with planting soil 5 in the cave body, this planting soil 5 is planted and has arbor 8, and cave body top exceeds saline and alkaline soil layer 1 surface, is equipped with barrier layer 3 between 5 sides of planting soil and saline and alkaline soil layer 1, and 3 soil property of this barrier layer are loess, thickness 15 centimetres. The planting soil 5 is foreign soil which does not contain salt and is rich in nutrient substances, the shape of the hole body is an inverted round table, the diameter of the bottom of the hole body is 120 cm, the diameter of the top of the hole body is 150 cm, and the thickness of the hole body is 100 cm. The top of the hole body is 1 ten centimeters higher than the surrounding saline-alkali soil layer, so that the salt content of the saline-alkali soil layer 1 is effectively prevented from entering the hole body along with rainfall or running water, and the growth of the arbor 8 is influenced. And the impermeable layer 3 on the side surface of the cave body prevents the salt of the saline-alkali soil layer 1 from permeating into the nutrient soil 5 from the side surface.
A cushion layer 16 is arranged below the planting soil 5, and the cushion layer 16 is composed of broken stones and has the thickness of 20 cm. Salt discharge pipes 10 with the gradient of two thousandths are embedded in the saline-alkali soil layer 1 outside the hole body, the salt discharge pipes 10 are lower than the cushion layer 16, and the salt discharge pipes are made of PVC pipes with the diameter of 50 millimeters. The bottom of the cushion layer 16 is an inclined plane with the right end inclined downwards, a salt leading pipe 11 is arranged between the cushion layer 16 and the salt discharge pipe 10, and the salt leading pipe 11 is an L-shaped PVC pipe with the diameter of 15 mm. The upper end of the salt leading pipe 11 is inserted into the lowest part of the cushion layer 16, a net for blocking broken stones is fixed at the end, and the right end of the salt leading pipe 11 is communicated with the salt discharge pipe 10. Salt in the saline-alkali soil layer 1 is dissolved by the water and then upwards permeates the bed course 16, and the internal surplus moisture of cave also gets into the bed course 16, then gets into row's salt pipe 10 through leading salt pipe 11 and arranges away, guarantees the normal growth of arbor 8 roots. The same root salt discharge pipe 10 can be communicated with a plurality of cavities, so that the method is more convenient and efficient when arbors 8 are planted in batches, and the planting cost is reduced.
An annular infiltrating irrigation pipe 4 is arranged in the planting soil 5, the infiltrating irrigation pipe 4 is positioned around the root of the arbor 8, a water delivery pipe 9 is arranged in the saline-alkali soil layer 1, the infiltrating irrigation pipe 4 is communicated with the water delivery pipe 9, and the water delivery pipe 9 is a PVC pipe with the diameter of 32 mm. Due to the adoption of the irrigation mode of infiltrating irrigation, water and nutrients conveyed by the water conveying pipe 9 can directly reach the root of the arbor 8, and the limited water resource of the saline-alkali area is saved. The same water delivery pipe 9 can be communicated with a plurality of cavities, so that the arbor 8 is more convenient and efficient to plant in batches, the planting cost is reduced, and the labor intensity is reduced.
An isolation layer 14 and a base fertilizer layer 15 are sequentially arranged between the cushion layer 16 and the planting soil 5 from bottom to top. The isolation layer 14 is coarse sand with the thickness of 10-15 cm, and has the effect of isolating salt which returns upwards in the saline-alkali soil layer 1 at the bottom of the cave body. The bottom fertilizer layer 15 is an organic fertilizer with the thickness of 10 cm, and provides nutrients for the growth of the arbor 8.
A lower isolating film 12 is laid between the bedding course 16 and the saline-alkali soil layer 1, and an upper isolating film 13 is laid between the bedding course 16 and the isolating layer 14. The upper barrier film 13 and the lower barrier film 12 are geotextiles. Go up barrier film 13 and keep apart between barrier film 12 will bed course 16, saline and alkaline soil layer 1 and isolation layer 14, make and can not take place to run off and mix between bed course 16, saline and alkaline soil layer 1 and the isolation layer 14.
The upper surface of the planting soil 5 is covered with the covering film 6 made of geotextile, so that the moisture evaporation of the planting soil 5 is reduced, and the effects of ventilation and moisture preservation are achieved.
A supporting frame 7 is arranged above the acupoint body, and the supporting frame 7 adopts a four-leg supporting mode. Four supporting legs of 7 lower parts of support frame are fixed in saline and alkaline soil layer 1, and upper portion is fixed with 8 trunks of arbor, prevents that 8 occurrences of arbor from empting, has also played the effect of anti-wind.
Be equipped with water-proof prevention of seepage membrane 2 between prevention of seepage bed 3 and saline and alkaline soil layer 1, prevention of seepage membrane 2 is plastics and geotechnological cloth combined material, further reduces salinity edgewise infiltration to the cave internal in saline and alkaline soil layer 1.
