DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide a low-maintenance outdoor storage device for alpine meadows, which takes into account conditions such as water supply, ventilation, heat preservation, and improving the maintenance stock, and reduces dependence on the artificial maintenance environment.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 The present embodiment provides a low-maintenance outdoor storage device for an alpine meadow, comprising a shell 1, a meadow stacking unit and an automatic liquid adding component.

[0033] The shell 1 can keep the meadow block 16 inside it warm. The shell 1 is made of transparent material so that light can be irradiated into the shell 1. The top of the shell 1 has a groove 2, in which nutrients can be stored in advance. After rainwater enters the groove 2 or artificial water is injected into the groove 2, the nutrients are mixed with water to form a nutrient solution. A plurality of meadow stacking units are fixed to the inner side of the shell 1, and the plurality of meadow stacking units are distributed in at least two layers to make full use of the internal space of the shell 1 and increase the maintenance stock of the meadow block 16. The meadow stacking unit includes a support frame 3, a gravel layer 4, a mature soil layer 5 and a receiving layer 6. One end of the support frame 3 is fixed to the inner side wall of the shell 1, the gravel layer 4 is arranged on the upper side of the support frame 3, and the mature soil layer 5 is arranged on the upper side of the gravel layer 4. The receiving layer 6 is arranged on one end of the upper side of the mature soil layer 5 close to the axis of the shell 1, and the upper surface of the receiving layer 6 is an inclined surface or a curved surface to drain the nutrient solution received by the receiving layer 6 to the mature soil layer 5. The support frame 3 is tilted so that the nutrient solution in the cooked soil layer 5 flows toward the inner side wall of the shell 1. The automatic liquid adding assembly is used to provide nutrient solution to the meadow stacking unit, and the automatic liquid adding assembly includes a spraying structure 7, a connecting pipe 8 and a floating cover. The spraying structure 7 is fixed in the shell 1 and has a plurality of bottom through holes to spray the nutrient solution downward through the bottom through holes. The upper end and the lower end of the connecting pipe 8 are respectively connected to the groove 2 and the spraying structure 7 to transport the nutrient solution in the groove 2 to the spraying structure 7. The floating cover is detachably mounted on the upper end of the connecting pipe 8 to open when the nutrient solution in the groove 2 reaches a preset capacity and close when it is lower than the preset capacity. When the floating cover is opened, the lower surface of the floating cover is separated from the upper end surface of the connecting pipe 8, and the nutrient solution in the groove 2 enters the spraying structure 7 along the connecting pipe 8. When the floating cover is closed, the lower surface of the floating cover contacts the upper end surface of the connecting pipe 8, and the nutrient solution in the groove 2 cannot enter the spraying structure 7 along the connecting pipe 8. The receiving layer 6 of each meadow stacking unit is vertically opposite to part of the bottom through holes, so that each meadow stacking unit can receive the nutrient solution sprayed by the spraying structure 7 .

[0034] The working principle of the low-maintenance storage device in the alpine meadow field is as follows:

[0035] A meadow block 16 is cut out on the native meadow that needs to be peeled off and placed on the mature soil layer 5. A certain amount of nutrients is stored in the groove 2, and water is poured into the groove 2 at a certain frequency for a period of time, and then natural precipitation is relied on, and only once each is poured thoroughly during the dormant period in winter and the growing season in spring. The nutrient solution sprayed by the spraying structure 7 first falls on the receiving layer 6, and after the receiving layer 6 impacts and consumes energy, it flows to the mature soil layer 5 along the inclined surface or curved surface on the upper surface of the receiving layer 6, so as to avoid damage to the meadow block 16 caused by direct impact of the nutrient solution on the meadow block 16. Afterwards, the nutrient solution continues to flow toward the inner side wall of the shell 1 in the mature soil layer 5, gradually infiltrating the mature soil layer 5, and the excess nutrient solution eventually flows to the bottom of the shell 1 along the inner side wall of the shell 1. The mature soil layer 5 plays a role in nutrient supply and root maintenance of the meadow block. During the growth process of the meadow block 16, its root system penetrates into the mature soil layer 5 and absorbs nutrients in the mature soil layer 5. The pores of the support frame 3 and the gravel layer 4 play a role in ventilation and water permeability, ensuring oxygen supply to the roots of the meadow block 16. Since the floating cover can be automatically opened and closed under the drive of rainwater, manual operations can be reduced, and the maintenance process of the meadow block 16 can be reduced. Dependence on the artificial management environment.

[0036] In this embodiment, a drainage structure for discharging water in the housing 1 to the outside is provided at the bottom of the housing 1, and the drainage structure can be opened and closed. The drainage structure can be a two-way drainage valve 11, or other structures such as a leather plug.

[0037] In this embodiment, a boss 12 is provided at the center of the inner bottom surface of the housing 1, so that a water collecting groove is formed between the boss 12 and the side wall of the housing 1, and the drainage structure is located at the water collecting groove, which can facilitate the drainage of internal water. The drainage structure can be located on the side wall of the housing 1 or on the bottom surface of the housing 1.

[0038] In this embodiment, the spray structure 7 is fixedly connected to the housing 1 through the support rod 13. The upper end of the support rod 13 is fixedly connected to the spray structure 7, and the lower end of the support rod 13 is fixedly connected to the bottom surface of the housing 1. According to different actual needs, those skilled in the art may also choose other fixing methods of the spray structure 7, such as fixing the spray structure 7 to the lower surface of the groove 2.

[0039] In this embodiment, the floating cover includes a floating plate 9 and a guide rod 10 fixedly connected to the floating plate 9 . The guide rod 10 is slidably disposed on the inner side of the upper end of the connecting tube 8 to guide the movement of the floating plate 9 .

[0040] In this embodiment, the guide rod 10 is a hollow tube to reduce weight. The guide rod 10 passes through the floating plate 9, and the upper end of the guide rod 10 should be higher than the upper surface of the floating plate 9 by a certain distance, so that the nutrient solution in the groove 2 cannot flow into the hollow tube.

[0041] In this embodiment, one end of the support frame 3 is fixed to the inner wall of the housing 1 by an expansion screw 14. According to different actual needs, those skilled in the art may also choose other types of fixing methods.

[0042] In this embodiment, the meadow stacking unit further includes a filter screen 15, which is located between the gravel layer 4 and the inner wall of the housing 1. The aperture of the filter screen 15 should be selected according to the size of the gravel, so that the gravel can be intercepted by the filter screen 15 to prevent the gravel from clogging the interface of the expansion screw 14.

[0043] In this embodiment, the shell 1 is made of an acrylic plate. According to different actual needs, those skilled in the art may also choose a shell 1 made of other transparent materials such as glass.

[0044] In this embodiment, the meadow stacking units are distributed in four layers, each layer includes two meadow stacking units, and the two meadow stacking units in each layer are symmetrically distributed about the center line of the housing 1. According to different actual needs, those skilled in the art may also select meadow stacking units of other layers such as three layers.

[0045] In this embodiment, the groove 2 is an inverted square pyramid structure. According to different actual needs, those skilled in the art may also select a groove 2 of other shapes such as an inverted cone structure.

The meadows in the stripping area are growing well and have uniform coverage.

[0048] Experimental plan: From March 2020 to December 2021, the inventors peeled off the meadow blocks in the implementation area and stacked them for storage, and measured the meadow block coverage, chlorophyll content, and root activity every 3 months. The plan set up 3 experiments, namely: Experiment 1 (using the low-maintenance storage device for alpine meadows in the field of this embodiment), Experiment 2 (placed on a wooden rack), and Experiment 3 (simple centralized stacking). Each experiment was set up with 3 replicates for mutual comparison.

[0049] The specific plan of Experiment 1 is:

[0050] (1) Stripping: Before construction, cut a 50 cm × 50 cm grid on the native meadow to be stripped, and then use a loader to shovel up the meadow along a plane 10 cm below the surface to form a 50 cm × 50 cm × 10 cm meadow block.

[0051] (2) Stacking: Place the peeled meadow blocks on the cultivated soil layer 5, with a total of 4 layers of meadow blocks. The air inlets and outlets are located in the dominant wind direction of the area to facilitate ventilation.

[0052] (3) Maintenance: After stacking is completed, water the meadow soil until it is fully soaked. Thereafter, water the meadow soil every 5 days to keep it moist for 20 days. Then, water the meadow soil once during the winter dormancy period and once during the spring growing season, depending on natural precipitation.

[0053] The specific plan for Experiment 2 is:

[0054] (1) Stripping: Before construction, cut a 50 cm × 50 cm grid on the native meadow to be stripped, and then use a loader to shovel the meadow along a plane 20 cm below the surface to form a 50 cm × 50 cm × 10 cm meadow block.

[0055] (2) Stacking: Construct a wooden rack with a height of 50 cm and four layers of meadow blocks, each 50 cm wide. Spread 6 cm of humus on each layer, and then spread meadow on the humus.

Then, water the meadow soil once during the winter dormancy period and once during the spring growing season, depending on natural precipitation.

[0057] The specific plan for Experiment 3 is:

[0058] (1) Stripping: Before construction, cut a 50 cm × 50 cm grid on the native meadow to be stripped, and then use a loader to shovel the meadow along a plane 30 cm below the surface to form a 50 cm × 50 cm × 10 cm meadow block.

[0059] (2) Stacking: Spread 6 cm thick native topsoil on the bottom layer, and stack the peeled meadow blocks in sequence without considering the gaps, for a total of 3 layers.

[0060] (3) Maintenance: After stacking is completed, water the meadow soil until it is fully soaked. Thereafter, water the meadow soil every 5 days to keep it moist for 20 days. Then, water the meadow soil once during the winter dormancy period and once during the spring growing season, depending on natural precipitation.

[0061] Test results:

[0062] In order to verify the stacking effect of different tests, sampling experiments were carried out in three stacking levels: upper, middle and lower. The top meadow layer was the upper layer, the middle two layers (Test 1 and Test 2) or the middle layer (Test 3) was the middle layer, and the bottom layer was the lower layer.

[0063] The measured indicators are chlorophyll content and root activity. The chlorophyll content is measured by ethanol extraction colorimetry; the root activity is measured by TCC staining.

[0064] Figure 2 The results of chlorophyll content determination under different tests are shown in Figure 2. Figure 3 The results of root activity measurement under different tests. It can be seen from the measurement results that the chlorophyll content of the meadow blocks in Test 1 and Test 2 is significantly higher than that in Test 3. Among them, the average meadow chlorophyll content in the middle layer of Test 1 is 12.51 mg / g, which is significantly higher than 7.39 mg / g in Test 2 and 4.67 mg / g in Test 3; the root activity of each layer of meadow is significantly different under different tests, and there is a phenomenon of Test 1> Test 2> Test 3. The extent of the decrease in meadow root activity between different stacking layers in Test 1 is not significant, and the root activity of the meadow between different stacking layers in Tests 2 and 3 is significantly decreased. The results show that the use of the low-maintenance storage device for the alpine meadow in the field of this embodiment can significantly alleviate the phenomenon of decreased chlorophyll content and root activity in the aboveground part of the meadow turf during the storage process, and the stacked meadows at all levels have significantly good vitality.
