Description

Technical Field

[0001] The invention relates to the field of land reclamation, and more specifically to a method and device for cultivating vegetation cover for land reclamation. Background Art

[0002] Desertification refers to the process in which grasslands with sandy surface environments in different climatic zones are affected by factors such as wind erosion, water erosion, drought, rodent and insect pests, and improper human economic activities, causing natural grasslands to suffer varying degrees of damage, erosion of sandy soil, soil sandification, a decrease in the organic matter content of sandy soil, loss of nutrients, and a decrease in grassland productivity, resulting in the grassland degradation process in originally non-desert areas, with a desert landscape similar to that characterized by wind and sand activities.

[0003] When repairing desertified grasslands, plants with well-developed root systems are generally planted. Their well-developed root systems can solidify the soil and reduce water and soil loss. However, desertified land is generally loose and has weak cohesion, resulting in poor water retention. Whether it is rainwater or irrigation water, its residence time in the desertified soil is short, resulting in water loss before the plant roots have time to absorb it. This not only causes a waste of water resources, but also results in a low survival rate of vegetation seedlings after planting. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a method and device for cultivating vegetation covering for land reclamation. Through the setting of a water-retaining ball net, the vegetation seedlings are located in the grid gaps of the water-retaining ball net. When watering the vegetation seedlings or in rainy weather, the water-retaining ball net can effectively absorb and store part of the water, effectively gather part of the water that cannot be absorbed and utilized by the root system in time, prolong the time that the water stays around it, effectively increase the amount of water absorbed by the vegetation root system, improve the utilization rate of water resources, and the gathered water is distributed in a multi-point mesh around the plant seedlings. When the humidity of high-temperature desertified soil is low, the upper heat-conducting rod transfers heat to the expansion sheet to make it expand and squeeze the embedded water-absorbing layer, so that the adsorbed water overflows, thereby timely replenishing the water required by the vegetation root system and improving its cultivation survival rate.

[0006] Technical solution: To solve the above problems, the present invention adopts the following technical solution.

[0007] A method for cultivating vegetation cover for land reclamation comprises the following steps:

[0008] S1. First, loosen the sandy soil and dig covering holes in a grid pattern;

[0009] S2. Align the water-retaining ball net with the covering hole and lay it on the sandy soil;

[0010] S3, then plant the seedlings in the gaps of the water-retaining ball net, and after planting, use sandy soil to bury the roots of the seedlings and the water-retaining ball net;

[0011] S4. After burying, water the seedlings. Part of the water will seep down along the sandy soil, and part of the water will be absorbed and stored by the water-retaining ball net.

[0012] S5. When high temperature causes the humidity of desertified soil to be low and the temperature to be high, the water-retaining ball net expands internally, squeezing the stored water to seep out into the desertified soil, replenishing water for the roots of plant seedlings and improving their survival rate.

[0013] Furthermore, vegetation seedlings are selected from plants with well-developed, densely crossed root systems and good coverage.

[0014] Furthermore, when the water-retaining ball net is buried, its upper end is kept above the sandy soil.

[0015] A cultivation device used in conjunction with a vegetation cover cultivation method for land reclamation includes a water-retaining ball net, which includes a plurality of criss-crossed limiting net ropes, a hot water replenishment ball is fixedly connected to the intersection of two limiting net ropes, an upper heat-conducting rod is fixedly connected to the upper end of the hot water replenishment ball, a longitudinal water seepage rod is fixedly connected to the lower end of the hot water replenishment ball, and the upper end of the upper heat-conducting rod is located above the sandy soil.

[0016] Furthermore, the longitudinal water seepage rod is made of a plurality of water-absorbing fibers wrapped with a water-soluble layer on the outside, the upper heat-conducting rod is made of a heat-conducting material, and the outer surface of the upper heat-conducting rod is coated with a black coating.

[0017] Furthermore, the hot water replenishment ball includes a porous water diffusion layer, a pressurized water ball located in the porous water diffusion layer, and an embedded water absorption layer filled between the porous water diffusion layer and the pressurized water ball, the interior of which is filled with high thermal conductivity gas, and the end of the upper heat conductive rod is fixedly passed through the porous water diffusion layer and fixedly connected to the pressurized water ball.

[0018] Furthermore, a plurality of evenly distributed water-retaining balls are fixedly inlaid on the inner wall of the porous water-scattering layer, and the water-retaining balls are made of a high-molecular water-absorbing resin.

[0019] Furthermore, the water pressure ball includes a diameter expansion piece and a plurality of diameter limiting pieces fixedly embedded on the diameter expansion piece, and a limit pull rope is fixedly connected between two opposite diameter limiting pieces.

[0020] Furthermore, the diameter limiting piece is a hard arc surface structure, and the diameter expanding piece is a spherical elastic structure.

[0021] Furthermore, the limit pull rope is made of non-elastic material, and the length of the limit pull rope is 1.2-1.5 times of the diameter.

[0022] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0023] This scheme uses the setting of a water-retaining ball net to place the plant seedlings in the grid gaps of the water-retaining ball net. When watering the plant seedlings or in rainy weather, the water-retaining ball net can effectively absorb and store some of the water, effectively gather some of the water that cannot be absorbed and utilized by the roots in time, prolong the time the water stays around it, effectively increase the amount of water absorbed by the plant roots, improve the utilization rate of water resources, and the gathered water is distributed in a multi-point mesh around the plant seedlings. When the humidity of high-temperature desertified soil is low, the upper heat-conducting rod transfers heat to the expansion piece to make it expand and squeeze the embedded water-absorbing layer, causing the adsorbed water to overflow, thereby timely replenishing the water required by the plant roots and improving its cultivation survival rate.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example: See Figure 1 , a method for cultivating vegetation cover for land improvement, comprising the following steps:

[0036] S1. First, loosen the sandy soil and dig covering holes in a grid pattern;

[0037] S2. Align the water-retaining ball net with the covering hole and lay it on the sandy soil;

[0038] S3, then plant the seedlings in the gaps of the water-retaining ball net, and after planting, use sandy soil to bury the roots of the seedlings and the water-retaining ball net;

[0039] S4. After burying, water the seedlings. Part of the water will seep down along the sandy soil, and part of the water will be absorbed and stored by the water-retaining ball net.

[0040] S5. When high temperature causes the humidity of desertified soil to be low and the temperature to be high, the water-retaining ball net expands internally, squeezing the stored water to seep out into the desertified soil, replenishing water for the roots of plant seedlings and improving their survival rate.

[0041] Vegetation seedlings are selected with well-developed, densely crossed root systems and good coverage, so that after they survive, they have good covering and soil-fixing capabilities for sandy soil. When the water-retaining ball net is buried, its upper end is kept above the sandy soil, that is, the upper end of the upper heat-conducting rod 3 is located above the sandy soil. On the one hand, it is convenient to locate the position of the hot water-replenishing ball 2. On the other hand, under high temperature conditions, the part above the sandy soil can quickly absorb and accumulate heat, and transfer the heat to the water-retaining ball net under the sandy soil, causing it to expand and squeeze out the water adsorbed inside it, thereby achieving the effect of replenishing water to the sandy soil in a multi-point mesh when the humidity of the high-temperature sandy soil is low, thereby effectively replenishing the water required by the roots of vegetation and improving its cultivation survival rate.

[0042] See also Figure 2-Figure 3 , a cultivation device used in conjunction with a vegetation covering cultivation method for land reclamation, comprises a water-retaining ball net, the water-retaining ball net comprises a plurality of criss-crossed limiting net ropes 1, a hot water replenishment ball 2 is fixedly connected at the intersection of two limiting net ropes 1, an upper heat-conducting rod 3 is fixedly connected to the upper end of the hot water replenishment ball 2, and a longitudinal water-seepage rod 4 is fixedly connected to the lower end of the hot water replenishment ball 2, the longitudinal water-seepage rod 4 is made of a plurality of water-absorbing fibers wrapped with a water-soluble layer on the outside, and the water-soluble layer melts during watering, at which time the longitudinal water-seepage rod 4 can gather part of the water that cannot be absorbed and utilized by the root system in time, prolong the time that the water stays around it, effectively increase the amount of water absorbed by the vegetation root system, and improve the utilization rate, the upper heat-conducting rod 3 is made of a heat-conducting material, The outer surface of the upper heat-conducting rod 3 is coated with a black coating, so that it can absorb heat, so that the expansion piece 23 expands and squeezes the embedded water-absorbing layer 22, so that the water inside it overflows. The upper end of the upper heat-conducting rod 3 is located above the desertified soil. The upper heat-conducting rod 3 is used to absorb heat and conduct heat. At high temperatures, it transfers heat to the heat-replenishing water ball 2. The longitudinal seepage rod 4 enables it to extend longitudinally into the desertified soil. Under high temperature conditions, part of the water that seeps out of the heat-replenishing water ball 2 can quickly penetrate into the bottom of the desertified soil along the longitudinal seepage rod 4, so that the prepared root system below can quickly absorb the water. At the same time, the longitudinal seepage rod 4 can also absorb water from deep underground, thereby achieving the effect of guiding water to the prepared root system.

[0043] See also Figure 4 The hot water replenishment ball 2 includes a porous water dispersion layer 21, an expansion piece 23 located in the porous water dispersion layer 21, and an embedded water absorption layer 22 filled between the porous water dispersion layer 21 and the expansion piece 23. The expansion piece 23 is filled with a high thermal conductivity gas. The end of the upper heat conducting rod 3 is fixedly penetrated through the porous water dispersion layer 21 and is fixedly connected to the expansion piece 23. The inner wall of the porous water dispersion layer 21 is fixedly inlaid with a plurality of evenly distributed water retention balls 6. The water retention balls 6 are made of a polymer water-absorbing resin. The water absorption and water locking effect of the water retention balls 6 is better, and the water that cannot be absorbed by the embedded water absorption layer 22 and the root system in the future can be more stably absorbed and preserved.

[0044] See also Figure 5-Figure 6 The expansion piece 23 includes an expansion piece 232 and a plurality of diameter limiting pieces 231 fixedly embedded on the expansion piece 232. A limit pull rope 5 is fixedly connected between the two opposite diameter limiting pieces 231. The limit pull rope 5 effectively controls the expansion range of the expansion piece 23, so that the expansion piece 23 has a limited extrusion force on the embedded water-absorbing layer 22, so that under high temperature conditions, the embedded water-absorbing layer 22 still has a certain adsorption force for water or rainwater artificially poured in the sandy soil, achieving a certain water retention effect, so that the embedded water-absorbing layer 22 is not easy to have poor water absorption due to excessive extrusion. The diameter limiting piece 231 is a hard curved surface structure, and the expansion piece 232 is a spherical elastic structure. After being heated, the expansion piece 232 expands due to the heat, driving the diameter limiting piece 231 to move in the direction away from the center of the circle. At the same time, the hard material of the diameter limiting piece 231 makes it difficult for the limit rope 5 to deform under the tension of the limit rope 5 after being stretched straight. The limit rope 5 is made of non-elastic material, and the length of the limit rope 5 is 1.2-1.5 times the diameter of the expansion piece 23, which effectively limits the diameter of the expansion piece 23 after expansion to 1.2-1.5 times its own diameter, so that the expansion degree of the expansion piece 23 will not be too large, and effectively maintain the embedded water-absorbing layer 22 under high temperature. Good water adsorption capacity after extrusion.

[0045] By setting up the water-retaining ball net, the seedlings are placed in the mesh gaps of the water-retaining ball net. When watering the seedlings or in rainy weather, the water-retaining ball net can effectively absorb and store some water, effectively gather some water that cannot be absorbed and utilized by the roots in time, prolong the time the water stays around it, effectively increase the amount of water absorbed by the roots of the plants, and improve the utilization rate of water resources. The gathered water is distributed around the seedlings in a multi-point mesh shape. In the case of high temperature and low humidity in desertified soil, please refer to Figure 6 The upper heat-conducting rod 3 transfers heat to the expansion piece 23 to make it expand and squeeze the embedded water-absorbing layer 22, so that the absorbed water overflows, thereby timely replenishing the water required by the roots of the vegetation and improving its cultivation survival rate.

[0046] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
