Description

Technical Field

[0001] The utility model relates to the technical field of saline soil experiments, in particular to a saline soil potting device. Background Art

[0002] During the saline soil pot experiment, some unconventional problems were encountered. First, it is difficult to manage the water in the saline soil of pots. If you follow the instructions in the experimental textbooks related to plant nutrition (such as "Plant Nutrition Research Methods" by Mao Daru), "the pot soil should be kept sufficiently moist", you need to water more water at the beginning of potting, or even directly water the pot soil thoroughly. However, in the actual saline soil pot experiment, from the perspective of soil, it was found that if too much water is poured, the soil will become muddy, heavy in texture, and even have the disadvantage of fertilizer loss. This is because saline soil contains a large amount of clay minerals, the soil structure is relatively tight, the porosity is small, and the water permeability and air permeability are poor. Secondly, if less water is poured, the surface of the pot soil will become dry and cracked. This is because the saline soil has poor tillage properties, which causes secondary obstacles such as poor pore structure, poor air permeability, and low water retention. When there is a lack of water, the soil hardness becomes larger and forms lumps. In addition, if water is poured from the bottom of the pot, the above situation will also occur.

[0003] Secondly, plants in saline soil pots are difficult to grow. Potting soil is the growth environment of plants and a key influencing factor in plant research. So from the perspective of plants, we found in actual experiments that when watering is less, it is difficult for water to penetrate into the seed layer 2-3 cm away from the surface of the potting soil. As a result, the seed layer was still dry after 7 days of cultivation, and the seeds did not germinate. At the same time, if too much water is given, the muddy and poorly permeable soil is not suitable for plant growth. Even if the plant grows out, when the rhizosphere sample of the plant is taken at the end, it may be difficult to remove the plant roots from the muddy soil, making it difficult to obtain the rhizosphere soil sample of the plant. Therefore, no matter how much or how little water is poured, it may have an adverse effect on the growth of the plant, which is not conducive to the development of potted experiments.

[0004] In addition, the conventional potted plant test weight method for quantitative watering is too time-consuming and labor-intensive. Conventional potted plant tests generally require the weight method to ensure that the water poured into each pot is quantitative. During the test, it was found that the range of the electronic balance must be large enough to meet the quality of potted plant watering (because the potted plants must be placed on the balance for weighing to ensure that the effective water holding capacity of the soil of each potted plant is maintained at around 60%).

[0005] In summary, it is necessary to develop a saline soil potting device that can water quantitatively. Utility Model Content

[0033] As a preferred embodiment of the present invention, see Figure 6 The annular clamp 6 is pin-connected by two semicircular clamps.

[0034] As a preferred embodiment of the present invention, the outer edge of the bottom of the annular cup 3 is inclined toward the center of the pot, so that the added water can all penetrate into the potting soil through the hole ring.

[0035] Example 1

[0036] In this embodiment, the saline soil potting device is a potting pot with an inner edge, see Figures 1 to 3 , including a pot body, an inner edge line 1 of the pot, a hole ring 2 and an annular cup 3. The inner edge line 1 of the pot is arranged on the upper part of the pot body and is used to determine the amount of potting soil used in potted plant tests (that is, the saline soil filling line in the pot during the experiment).

[0037] The hole ring 2 is a plurality of holes punched around the pot body, and the plurality of holes form an annular hole ring. The hole ring 2 is arranged at the lower part of the inner line 1 of the pot for watering. The hole ring 2 is 2-3 cm high from the inner line 1 of the pot, the hole diameter is 5 mm, the hole spacing is 5 mm, and the hole ring height is 2 cm. Seeds are generally planted at a soil depth of 3 cm. The hole ring 2 is arranged at a distance of 2-3 cm from the inner line 1 of the pot. Punching holes for watering here allows water to be directly irrigated to the seed layer, thus avoiding the situation where the saline soil is less watered and it is difficult to penetrate into the seed layer, making it difficult for the seeds to germinate.

[0038] The annular cup 3 is arranged outside the hole ring and is used to add water outside the hole ring. The outer edge of the bottom of the annular cup 3 is inclined toward the center of the pot, so that the added water can all penetrate into the potting soil through the hole ring. The greater the inclination, the better. The greater the inclination is to allow the added water to penetrate into the potting soil through the hole ring 2.

[0039] The annular cup 3 also includes a quantitative water outlet pipe, which is arranged outside the annular cup and is used for quantitative water outlet (when the added water exceeds the predetermined water level, the excess water flows out through the quantitative water outlet pipe). According to the water management plan of the potted plant experiment, quantitative water outlet pipes with different water levels can be set. For example, the quantitative water outlet pipes in this embodiment include quantitative water outlet pipes a4 and quantitative water outlet pipes b5 arranged from top to bottom, wherein the quantitative water outlet pipe a4 is arranged at the 200 mL water level in the annular cup 3, and the quantitative water outlet pipe b5 is arranged at the 100 mL water level in the annular cup 3. In this way, when 100 mL of water needs to be added quantitatively, the quantitative water outlet pipe b5 at the bottom is used; when 200 mL of water needs to be added quantitatively, the quantitative water outlet pipe a4 at the top is used, and the outlet of the quantitative water outlet pipe b5 is blocked with a rubber plug sleeve or a pipe plug.

[0040] See also Figure 4 , the potted plant device also includes an annular clamp 6, which is detachably mounted on the outside of the hole ring 2. In this embodiment, the annular clamp 6 uses a C-type clamp with one side open, and the open end is pinned. It can also be fixed by a cable tie, which can achieve detachability and block the hole ring 2 at the same time. The purpose of the annular clamp 6, that is, the hole ring cover, is to cover the hole ring when no water is added at ordinary times to prevent soil from leaking out of the hole ring. Secondly, in order to prevent water from penetrating into the potted soil from the hole ring before the water level reaches the water level line for quantitative water addition when adding water, the hole ring can be covered with the annular clamp 6 before adding water. After reaching the water level line, the annular clamp 6 is removed.

[0041] The method of using the saline soil potting device of the present invention is as follows: when quantitative (100 mL) watering is required, cover the hole ring 2 with the annular clamp 6 (the opening of the annular clamp 6 is pinned, and the pin and the annular clamp 6 are assumed to be a matching structure, or connected by a cable tie, which is adjusted according to experimental conditions), confirm that the quantitative water outlet pipe b5 remains unobstructed, add water into the annular cup 3, and when the water volume exceeds 100 mL, it will flow out along the quantitative water outlet pipe b5, and then remove the annular clamp 6, so that the water penetrates into the saline soil to be watered inside the pot along the hole ring 2, and the quantitative watering is completed.
