Description

Technical Field

[0001] The utility model relates to the technical field of saline-alkali land planting, in particular to a special planting device for saline-alkali land. Background Art

[0002] Saline-alkali land is a type of salt accumulation. The salt contained in the soil affects the normal growth of crops. For areas with severe salinity, it is basically difficult to grow crops. The soil in the area needs to be improved to meet the conditions for planting, including large-scale water injection or large-scale backfilling of imported soil, but the amount of work is relatively large, or burying salt drainage pipes in the saline-alkali land, the cost is very high, and the effects of the above methods are relatively slow, and it takes a long time to improve the soil in the saline-alkali land. The soil treated in a short time is still in a state where it cannot be planted, and the problem of not being able to plant in the area cannot be solved in a timely and effective manner. In addition, existing planting devices all have water outlets at the bottom for convenient use in normal soil planting, but when used in saline-alkali areas, the salt in the soil will seep into the planting device, affecting the composition of the nutrient soil in the planting device, and then affecting the normal growth of crops. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a special planting device for saline-alkali land.

[0004] The technical solution of this utility model is as follows:

[0005] A special planting device for saline-alkali land comprises a planting bag body, wherein a sealing layer is arranged at the upper end of the planting bag body, and a sealing layer is connected to the bottom end, a bottom layer pressing edge is arranged at the bottom of the planting belt body, and a planting bag folding edge is arranged on the side;

[0006] The sealing layer is provided with a planting hole, and the planting hole is connected to the inside of the planting bag body;

[0007] The planting bag body is provided with a plurality of balancing holes near the sealing bottom layer, and the balancing holes are communicated with the interior of the planting bag body.

[0008] In order to facilitate placement in saline-alkali land and planting, the planting bag body has a square cross-section, and the height of the planting bag body is smaller than its length.

[0009] In order to facilitate the breathing of the roots of the planted crops and prevent the roots from being soaked by liquids such as nutrient solution or fresh water, the planting bag body has at least two balancing holes on its sides. Excess nutrient solution or fresh water can flow to the saline-alkali land around the planting bag body at the balancing holes, slowly absorbing the salt in the surrounding soil, and improving the surrounding soil after long-term use.

[0010] In order to facilitate the fluidity of air in the planting bag body and form convection, balancing holes are opened on two sides of the planting bag body, and the two sides are opposite to each other.

[0011] In order to ensure that the number of holes can ensure normal ventilation and the normal outflow of excess moisture, each side is evenly distributed with four balancing holes along the length direction, and the distance between the balancing holes and the sealing layer is 3cm-8cm.

[0012] In order to ensure that the liquid level of the water or nutrient solution in the planting bag body meets the needs of crop growth, the distance between the balance hole and the sealing layer is 5 cm.

[0013] In order to provide the roots of the seeds sown in the planting holes with a larger and more even growth space around them when they grow, the planting holes are opened at the center of the sealing layer.

[0014] In order to match the round stems of most crops and facilitate the smooth outflow of water, the planting hole and the balancing hole are both circular holes, and the diameter of the planting hole is larger than the diameter of the balancing hole.

[0015] In order to adapt to the stem growth of most crops and ensure water outflow while preventing nutrient soil from falling, the diameter of the planting hole is 1 / 5-2 / 5 of the length of the planting bag body, and the diameter of the balance hole is 3cm-6cm.

[0016] In order to facilitate the disposal of planting devices that have been used for a long time and avoid pollution to the environment, the planting bag body, the sealing layer and the bottom sealing layer are all made of degradable materials.

[0017] The beneficial effects of the utility model are as follows: the utility model is a special planting device for saline-alkali land, which first changes the way of first improving the saline-alkali land area and then planting, and uses the planting device to directly plant in the saline-alkali land area, which is convenient and fast, with low cost, and meets the local demand for crops. In addition, the planting device is easy to operate, whether it is directly placed in the saline-alkali land area during planting, or directly placed in the area for recycling after use, it does not take much time to achieve planting and recycling. Secondly, the sealing layer can effectively reduce the loss of nutrients in the planting bag, and the planting hole is convenient for operation. The balancing holes facilitate the breathing of crop roots and avoid the damage of crop roots by excessive water and other liquids. The side openings are more suitable for planting in saline-alkali land, which greatly reduces the infiltration of salt into the planting bag. The most important thing is that nutrient solution or fresh water and other liquids can flow out at the balancing holes and eventually flow to the saline-alkali land, which can dilute and absorb the salt in the surrounding saline-alkali land. After a long period of dilution and absorption, the soil around the planting bag can be improved, achieving the effect of planting and improving the saline-alkali land, which is of great significance for the harvest of crops and soil improvement in severe saline-alkali areas.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, the utilization of saline-alkali land is currently of great research value. For severely saline-alkali land, the soil must be improved before subsequent planting. The existing improvement technologies usually have the same defects. On the one hand, the investment cost is huge and a long improvement time is required. Effective improvement cannot be completed in a short time, making it impossible to plant immediately in the saline-alkali land area, affecting the use of the saline-alkali land and the economic benefits. Therefore, the inventor designed a planting device in the process of soil improvement, which is specially used for the use of severely saline-alkali land, so that the soil can be improved while planting, which effectively solves the above problems. The following is a detailed explanation with reference to the drawings.

[0028] This embodiment provides a special planting device for saline-alkali land. Figure 1 , including a planting bag main body 1, a plurality of planting bag main bodies 1 are placed at intervals in the saline-alkali land area, and the intervals between adjacent planting bag main bodies 1 are 1m-3m, and in order to facilitate placement on the ground, the planting bag main body 1 has a square cross-section, and the height of the planting bag main body 1 is less than its length, the side length of the cross-section is between 25cm-35cm, and the height is between 20cm-30cm. In this embodiment, the side length of the cross-section is 30cm and the height is 25cm. This size can meet the root growth of most crops suitable for planting in saline-alkali land.

[0029] In this embodiment, combined with Figure 1 and Figure 2 A sealing layer 2 is provided at the upper end of the planting bag main body 1, and a sealing layer 3 is connected to the bottom end. A bottom pressing edge 4 is provided at the bottom of the planting belt main body, and a planting bag folding edge 5 is provided on the side, both of which are provided with four. By arranging the bottom pressing edge 4 and the planting bag folding edge 5, the planting bag main body 1 can be shaped and more stable. The setting of the sealing layer 2 can reduce the contact space between the inside and outside of the planting bag main body 1, and can effectively maintain the internal nutrient soil components.

[0030] It should be noted that the planting bag body 1, the sealing layer 2 and the bottom sealing layer 3 are all made of degradable materials. The entire planting device can be used for 3-5 years. After use, it cannot be removed and can be disposed of on site. The degradable materials will not cause secondary pollution to the soil, which facilitates subsequent treatment.

[0031] On the basis of the above structure, the sealing layer 2 is provided with a planting hole 6, and the planting hole 6 is connected to the inside of the planting bag body 1. Figure 3 In order to provide a larger and uniform space around the roots of the crops, the planting hole 6 is opened at the center of the sealing layer 2. The planting hole 6 is a circular hole, which matches the stems of most crops, and the diameter of the planting hole 6 is 1 / 5-2 / 5 of the length of the planting bag body 1. In this embodiment, the diameter of the planting hole 6 is 8 cm, which minimizes the contact space between the inside and outside of the planting bag body 1 while ensuring the growth space of the crop stems.

[0032] The main invention point of the present scheme is that a plurality of balancing holes 7 are provided near the sealing layer 3 of the planting bag main body 1, and the balancing holes 7 are circular holes with a diameter smaller than the diameter of the planting holes 6, and the balancing holes 7 are connected to the inside of the planting bag main body 1, and the planting bag main body 1 has at least two side surfaces with balancing holes 7. In the present embodiment, the balancing holes 7 are provided on two side surfaces of the planting bag main body 1, and the two side surfaces are opposite to each other. The balancing holes 7 are provided on the two opposite sides, which ensures that air can circulate, provides sufficient oxygen to the roots of the crops inside, and ensures the breathing of the roots.

[0033] On the basis of the above design, each side is evenly distributed with four balancing holes 7 along the length direction, and the distance between the balancing holes 7 and the sealing layer 3 is 3cm-6cm, which is evenly distributed along the length direction to ensure that multiple positions of the crop roots can absorb sufficient oxygen. In this embodiment, the distance between the balancing holes 7 and the sealing layer 3 is 5cm, so that part of the water or nutrient solution can be retained in the planting bag body 1, which can effectively prevent the roots from being deprived of water and drying up when the temperature is too high, and it should not be too high to avoid excessive water and root rot.

[0034] In order to ensure the circulation of air and the outflow of water, the diameter of the balancing hole 7 is 3cm-8cm. In the present embodiment, the diameter of the balancing hole 7 is 5cm. The setting of the balancing hole 7 is of great value to the growth of crops and the improvement of the soil around the planting bag body 1. The balancing hole 7 can ensure the entry of oxygen so that the roots can breathe normally. Secondly, since fresh water is injected into the planting bag body 1, excess water can flow out at the balancing hole 7 and finally flow into the soil around the planting bag, which can dilute and absorb the salt in the saline-alkali land. After 3-5 years of use, the soil within 1m around a planting bag body 1 can be improved, achieving the effect of improving the saline-alkali soil while planting, which is of great value for the utilization and improvement of severe saline-alkali land.
