[0002] Limestone slag is the focus of mine ecological restoration. Most limestone slag has large pores, poor water retention, little soil, and poor soil, which makes it difficult for mine ecology to recover naturally. A certain amount of soil is mixed into the slag to improve it so that it meets the living conditions of plants. In the specific research process, it is necessary to make several sample plot devices to accommodate the improved slag. By studying the effects of different soil contents in limestone slag on the growth of different plants, the interval values of survival and growth of different plants in limestone slag are given, which has very important guiding significance for guiding the greening and reclamation of limestone slag.
[0003] At present, the sample plot device used in the experiment is assembled from discarded wooden boards or plastic boards into an open box at the top. Different plants are planted in limestone slag with different soil contents in the box, and the surface is covered with cultivation plastic film, and irrigation is carried out at regular intervals. Since the materials used to make the sample plot device are waste, they are all disposable and cannot be reused, and they need to be remade for the next test. Moreover, the film covers the surface of the modified slag in the box, and the film needs to be opened during the irrigation process. The film after irrigation needs to be covered again, which is time-consuming and laborious for one person to operate. In addition, the film is very easy to tear during the repeated opening and covering process, and the secondary coating will lead to increased costs. Utility Model Content

[0024] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following will describe the embodiments of the present utility model in conjunction with the accompanying drawings.
[0025] like Figure 1 As shown, a sample plot device for studying the effect of limestone slag improvement on plant growth comprises a rectangular box 1 with an opening at the top, a side wall of the box 1 is provided with an interlayer for accommodating a film roll, and a long strip opening 2 is provided on the top of the interlayer for the film to pass through; a fastening structure 3 for clamping the film is provided around the top of the box 1. The width of the film is greater than the width of the box, and can completely cover the upper opening of the box 1. When in use, the length of the film is extracted as needed and covered on the top of the box, and the film is clamped and fixed by the fastening structure; when irrigating, the film roll is rotated in the opposite direction to retract the film, and the film is pulled out after irrigation, thereby reducing the waste of film.
[0026] As a preferred structure, Figure 1 As shown, the outer wall of the interlayer is a split structure, including a fixed plate 4 and a movable plate 5 from top to bottom. The upper end of the movable plate 5 is rotatably connected to the lower end of the fixed plate 4 through a hinge 6. The film roll is arranged on a rotating shaft 7. The two ends of the rotating shaft 7 respectively pass through the end plates on both sides and rotate with them.
[0027] In order to conveniently rotate the film roll, one end of the rotating shaft 7 can be extended to the outside of the box body 1 and connected to a crank (not shown). When in use, the crank can be used to conveniently realize the forward and reverse rotation of the film roll, and the film can be easily extracted or retracted.
[0028] During specific production, the lower part of the movable plate 5 is provided with a convex arc to match the shape of the film roll. This structure can form a circular or approximately circular space between the movable plate and the inner wall of the interlayer, which is convenient for installing the film roll.
[0029] To further optimize the above solution, a roller 8 for squeezing the film onto the inner wall of the interlayer is provided on the upper part of the interlayer, and both ends of the roller 8 are rotatably matched with the interlayer end plate. The roller can prevent the film from shrinking after being pulled out.
[0030] In a specific embodiment of the present invention, Figure 1 As shown, the fastening structure 3 includes a plurality of positioning shafts 31 perpendicular to the outer wall of the box body 1. The positioning shafts 31 near the outer walls at both ends of the interlayer are connected to elastic elements 32, and the elastic elements 32 can press the edges of the film in sequence. Among them, the elastic element can be a rubber band or an elastic rope. When the film is pulled out and covered on the top of the box body, the edge of the film can be fixed by the rubber band.
[0031] To further optimize the above solution, anchor rods 9 are provided at the bottom of the four corners of the box 1, and the lower ends of the anchor rods 9 are provided with pointed heads for inserting into the ground. The anchor rods can fix the box on the ground to avoid displacement due to collision during the test.
[0032] In specific implementation, the thickness of the modified slag filled in the box 1 is not less than 50 cm, and the internal size of the box 1 is not less than 0.8 m*1.5 m to meet the needs of plant growth. At the same time, the bottom edge of the box 1 is provided with a water-permeable hole (not shown in the figure) to drain excess water out of the box.
[0033] To facilitate irrigation, Figure 2 As shown, a spray pipe 10 can be set up on the top of the box 1, and the spray pipe 10 is provided with a plurality of nozzles 11 with downward outlets; there are more than two spray pipes 10, and their inlet ends are connected to a connecting pipe 12, and the inlet of the connecting pipe 12 can be connected to the water outlet of a water tank 14 through a hose 13. Among them, the end of the spray pipe 10 is provided with a downward bend, which is convenient for setting up on the top of the box to avoid slipping. The water tank 14 is placed on a trolley 15, which is convenient for moving between different boxes to irrigate the plants in all boxes.
[0034] According to the test requirements, the number of boxes produced is no less than 24. The emergence rate, survival rate, growth of plants in the boxes and basic soil characteristics are monitored regularly, and data records are kept. Through statistical analysis of plant growth status and soil characteristics, comprehensive research is conducted to draw conclusions under different ratios. The specific test process is as follows:
[0035] We selected different proportions of soil and different plants, and designed 6 groups of different proportions of soil and different plants, with a total of 24 box plots:
[0036] Experimental group 1: corn seeds were used, and the amount of soil mixed into the six groups of limestone slag (volume ratio) was 0%, 8%, 16%, 24%, 32%, and 40%, respectively, and all contained 10% organic fertilizer;
[0037] Experimental group 2: 6 groups of slag with different soil contents + 10% organic fertilizer + creeper seeds;
[0038] Experimental group 3: 6 groups of slag with different soil contents + 10% organic fertilizer + Amorpha fruticosa seeds;
[0039] Experimental group 4: 6 groups of slag with different soil contents + 10% organic fertilizer + Sophora japonica seeds;
[0040] According to the ratio of the matrix, the matrix was mixed manually, and suitable plant species were selected. Plants that are sensitive to limestone slag and have a certain adaptability to changes in environmental conditions should be selected. Ensure consistent planting methods, such as sowing depth, density, and irrigation methods. The plants selected for planting are corn, Amorpha fruticosa, Sophora japonica, and Parthenocissus tricuspidata. They are planted evenly according to the size of the box sample. According to the data, the growth of plants is different in different soil ratios. The greater the proportion of mixed soil content, the better the plant growth effect, the higher the soil fertility retention, and the higher the water retention. This was reflected in Group 1, Group 3, and Group 4. The creeper in Group 2 failed to continue to grow due to light-avoidance problems, and Group 1 had the best growth.
[0041] In summary, the utility model has the advantages of simple structure and convenient and quick operation. By rotating the film roll in the interlayer of the box, the box can be easily covered or opened for irrigation. The film can be repeatedly extended and retracted, reducing film waste. The water tank can be moved between different box samples by a trolley, and the spray pipe can be conveniently set up on different boxes to complete irrigation. The utility model can be used to master the water and soil conservation performance of slag under different ratios through different tests, and the plant growth law provides technical support for limestone mine slag greening, leveling and slag improvement.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
