Description

Technical Field

[0001] The utility model relates to a plant growth and cultivation device, in particular to a non-natural soil matrix plant cultivation device. Background Art

[0002] In ecological restoration research, in-depth understanding of the interaction between plants and microorganisms will help accelerate the process of ecological restoration. Researchers have studied the interaction mechanism between plants and microorganisms through indoor pot experiments to exclude the influence of the external natural environment and indigenous microorganisms. However, the nutrient composition in the soil is extremely complex, and indoor soil matrix pot experiments still cannot meet the cultivation conditions required for mechanism research. Some studies have cultivated plants in non-natural soil matrices by mixing relatively pure substances such as vermiculite, quartz sand, glass beads and perlite. However, there are large differences in the physical properties of non-natural soil growth matrices and soil matrices, especially poor water retention. After irrigation from the surface, the upper matrix often has a low moisture content, but the lower matrix has a high moisture content. This makes watering difficult and it is impossible to determine the amount of water. Watering too frequently and a large amount of water will cause the moisture content in the lower matrix to be too high, affecting root respiration; watering is too scarce, resulting in too low moisture content in the upper matrix, and the plant roots cannot grow normally, and they grow concentrated in the lower matrix, which is seriously inconsistent with the natural growth conditions of plant roots and will affect the scientificity and objectivity of the experiment. At present, there is a soilless cultivation technology in agriculture, where crops are suspended in a closed cultivation device (trough, box or bed), and the roots are exposed inside the cultivation device. The nutrient solution is atomized into small droplets using a spray device and sprayed directly onto the plant roots to provide the water and nutrients required for plant growth. This method also has a great disadvantage. It can only be used to cultivate plants in non-soil matrices, and cannot be used to cultivate plants that require non-natural soil matrices. Therefore, for the cultivation of plants in non-natural soil matrices, special devices are needed to achieve scientific and objective cultivation of plants and study the interaction mechanism between plants and microorganisms.

[0057] Example

[0058] 1. Determine the shape of the potting container

[0059] like Figure 1 As shown, in this example, the potted container is a rectangular block with a length × width × height of 30 cm × 10 cm × 12 cm. The container is divided into three parts, with plant growing rooms (mycorrhizal rooms) at both ends and a mycelium room in the middle.

[0060] 2. Determine the raw materials and ratio of the growth matrix

[0061] In this example, perlite and glass beads are selected with a ratio of 1:1.

[0062] 3. Design and install the spray device and fill the growth medium

[0063] For the growth chamber with continuous growth substrate, the spray device is set up. The spray device is generally arranged in single layer parallel or multi-layer vertical, and is installed on the cultivation device ( Figure 1 ). A single layer uses a soft plastic tube (spray tube) with an inner diameter of 2mm. The spray tube only has small holes with a diameter of 1mm at a distance of 0.5cm in the growth device for the passage of water mist. The horizontal distance between two adjacent spray tubes is 1cm. For vertical multi-layers, an additional layer of spray tube is added at a height of 5cm. An additional layer of spray tube is added to the bottom layer, an additional layer of spray tube is added to the surface layer, and an additional layer of spray tube is added to the middle layer. The spray holes of the spray tubes on the bottom layer face upwards, and the spray holes of the spray tubes on the surface layer face downwards. The spray holes of the spray tubes on the bottom layer and the surface layer have only one row in one direction (see Figure 2 The spray holes of the middle layer spray pipe are oriented in four directions: up, down, left, and right. A row of spray holes is set in each of these four directions (see Figure 2 In (b), water mist is allowed to pass through.

[0064] After installing the bottom layer of spray tubes, fill in a 5 cm high growth substrate, then lay a middle layer of spray tubes, then fill in another 5 cm high growth substrate, and finally lay a layer of spray tubes at the soil and air interface.

[0065] like Figure 3 The figure shows the installation of the gas phase ball group. During the process of filling the growth substrate, a layer of gas phase balls 9 is placed around the wall of the potting container (i.e., the cultivation device 7) at a height of 2.5 cm from the bottom of the soil, 2 cm from the wall of the potting container, and the distance between adjacent gas phase balls in the same layer is 4 cm (e.g., Figure 5 as shown).

[0066] The gas phase ball set includes a gas phase ball 9 and an electromagnetic device 8. The gas phase ball 9 is composed of three parts, a spherical shell 91, a central axis 93, and a rotor 94. The electromagnetic device 8 is attached to the outer wall of the potted container.

[0067] The spherical shell 91 is made of plastic, has a diameter of 6 mm, a spherical wall thickness of 0.5 mm, is hollow, and has 12 micropores 92 evenly distributed on the spherical wall, and has a diameter of 0.5 mm.

[0068] The rotor 94 is made of magnetic stainless steel, similar to a fan, with a fan angle of 60-120°, and a hole at the center of the fan. The central axis 93 is placed in the spherical shell, and the rotor 94 is placed on the central axis 93 through the hole. In the natural state, the fan in the rotor 94 points to the direction of gravity. When the electromagnetic device 8 nearby is powered on to generate a magnetic field, the rotor 94 will be attracted toward the direction of the electromagnetic device 8 under the action of the magnetic force. The fan shape of the rotor 94 will drive the air flow in the gas phase ball 9, and then drive the gas phase flow in the growth matrix.

[0069] The electromagnetic device 8 includes a coil 84, a wire 83, a switch 81 and a power supply 82. The coil 84 can be attached to the outer wall of the potted container. The direction of the magnetic field generated by the coil 84 is perpendicular to the central axis of the gas phase ball and passes through the center of the gas phase ball 9. The electromagnetic device 8 and the gas phase ball 9 correspond one to one. The coils 84 of the electromagnetic device 8 can be powered and controlled individually, or in groups or in a unified manner. See the schematic diagram of the combined structure of the cultivation device 7 and the gas phase ball group. Figure 6 The power supply 82 is an intermittent power supply setting, which generates magnetic force intermittently. When the magnetic force is generated, the rotor is attracted laterally. When there is no magnetic force, the rotor 94 remains in a drooping state. The power switch 81 time is twice the spray time of the bottom spray pipe 1, and the opening time is synchronized with the opening time of the spray pipe.

[0070] 4. Set the spray time and spray duration

[0071] According to the actual situation, the moisture in the surface matrix is ​​easy to evaporate, while the moisture in the middle and bottom layers is not easy to evaporate. The duration of the surface matrix spray is set to be 3 times that of the middle and bottom layers. The duration of the middle and bottom layer soil moisture spray is synchronized. The daily water replenishment of the bottom layer soil moisture is generally based on 40mL / kg growth matrix.

[0072] 5. Summary

[0073] The device of the utility model is innovative in consideration of the actual situation that it is difficult to replenish water for plants in non-natural soil matrices. The device of the utility model solves the following problems: (1) it is difficult to replenish water for non-natural soil matrices, and the replenishment is uneven, which affects the growth and development of plant roots; (2) soil moisture at different levels is affected differently by the external environment, and the replenishment amount needs to be controlled separately; (3) soil moisture at different levels is used differently by plants, and the replenishment amount needs to be controlled separately; (4) the replenishment amount of different compartments in the compartment cultivation device is different; (5) the device of the utility model can atomize deuterium-labeled water as needed and then replenish it into the growth matrix through the spray pipe to study the effect of plant absorption of water on water transportation and distribution.
