Abstract
Description
Technical Field
[0001] This utility model relates to the field of modern agricultural technology, and in particular to a simple device for hydroponics of tomatoes. Background Technology
[0002] As of 2020, my country's tomato cultivation area exceeded 1.1115 million hectares, with a total tomato output of 64.8658 million tons, accounting for 22% and 34.72% of the world's total, respectively. Among these, greenhouse cultivation area is showing a gradual expansion trend, currently exceeding 642,000 hectares, accounting for 57.89% of the total. However, due to the prevalence of soil-based cultivation in my country's greenhouse tomato cultivation, continuous cropping has become an inevitable trend with the increasing industrialization of agriculture. Furthermore, the limited leaching of soil in greenhouses leads to severe soil pollution, decreased fertility, and increased soil-borne pests and diseases, significantly impacting planting efficiency. Soilless cultivation technology, as an important method for high-quality and efficient modern vegetable production internationally, is the only effective measure to solve soil-related continuous cropping obstacles, improve fertilizer utilization, and increase yield and quality. Compared to soil cultivation, soilless cultivation can effectively increase fertilizer utilization by more than 60% and yield by more than 50%.
[0003] Currently, there are two main hydroponic cultivation models for tomatoes in my country: one is the coconut coir strip cultivation model, and the other is the semi-hydroponic cultivation model. Although these models have achieved some success, the following problems still exist:
[0004] (1) Coconut coir strip planting mode: Generally, coconut coir strips are placed directly on the planting rack for planting. However, this method has the following problems: 1) Large amount of coconut coir input. Taking a 1000 square meter greenhouse as an example, the number of coconut coir strips required is 560, the volume of a single coconut coir strip is 15L, and the total coconut coir input volume is 8400L; 2) Difficult to plant continuously. In terms of crop rotation, because coconut coir strips contain the roots of the previous crop and pathogens, it is impossible to plant continuously. Generally, only one crop can be planted, which increases the cost of coconut coir input and land preparation.
[0005] (2) Semi-soilless cultivation mode: Generally, planting trenches of 15cm (depth) * 15cm (width) are dug in each planting row in the field, then ground cover is laid in the trenches, then guide plates are laid, and coconut coir is laid on the guide plates; or coconut coir is laid directly in the trenches. This planting mode also has the following problems: 1) Large amount of coconut coir input: Taking a 1000 square meter greenhouse as an example, the total volume of coconut coir required is about 12600L; 2) Cannot completely isolate the influence of soil. During the planting process, the roots may penetrate into the soil along the coconut coir, causing pathogens in the soil to harm the crop roots; 3) High land preparation cost. After each crop is finished, all coconut coir needs to be cleaned up manually and new coconut coir needs to be laid, which increases the land preparation cost.
[0006] Based on this, in order to facilitate the better promotion of soilless cultivation technology, and to address the shortcomings of existing soilless tomato cultivation technology, a simple soilless tomato cultivation device is proposed to make soilless cultivation technology more practical. Utility Model Content
[0007] The purpose of this utility model is to provide a simple device for hydroponics of tomatoes, which uses flower pots for hydroponics to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A simple hydroponic tomato cultivation device includes an assembled tray, a plant fixing frame, and a shading support frame. The top surface of the assembled tray is recessed to form two cylindrical planting troughs. Each planting trough has four supporting protrusions at its bottom. Several buckles are provided on the sides of the top surface of the assembled tray. The assembled tray is assembled with at least one identical assembled tray through the buckles. The plant fixing frame is connected above the assembled tray and has two fixing holes, which correspond vertically to the two planting troughs. The shading support frame is connected above the plant fixing frame.
[0010] Preferably, the top surface of the assembled tray has a rectangular structure, including a first long side and a second long side, and a first short side and a second short side. The buckle includes a matching semi-circular protrusion and a semi-circular groove. The first long side and the first short side are provided with semi-circular protrusions, and the second long side and the second short side are provided with semi-circular grooves. Several assembled trays are spliced together by engaging the semi-circular protrusions with the semi-circular grooves.
[0011] Preferably, the plant fixing frame includes a first T-shaped bracket and two fixing holes. The first T-shaped bracket includes a first parallel section and a first vertical section perpendicularly connected to the center of the bottom surface of the first parallel section. The two fixing holes are respectively located at both ends of the first parallel section. Each fixing hole is composed of two semi-circular connecting pieces, forming a notch between the two semi-circular connecting pieces. An open circular hole is provided on the inner circular wall of the fixing hole.
[0012] Preferably, the first vertical section is a solid cylindrical structure, and a first pin is provided at the bottom of the first vertical section. A first insertion hole is provided on the assembled tray between the two planting troughs. The first pin matches the first insertion hole, and the plant fixing frame is connected to the assembled tray by inserting the first pin into the first insertion hole.
[0013] Preferably, the shading support frame includes a second T-shaped bracket, which includes a second parallel section and a second vertical section perpendicularly connected to the center of the second parallel section. Two support holes are respectively opened at both ends of the second parallel section. The second vertical section is a solid cylindrical structure. A second pin is provided at the bottom of the second vertical section. A second insertion hole is provided at the center of the top surface of the first parallel section. The second pin matches the second insertion hole. The shading support frame is connected to the plant fixing frame by inserting the second pin into the second insertion hole.
[0014] Preferably, the top surface of the assembled tray and the two planting troughs are provided with several hollow openings.
[0015] Preferably, the assembled tray, plant fixing frame, and sunshade support frame are all made of plastic.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1) The simple hydroponic tomato cultivation device of this utility model can be placed directly on the planting row, requiring only land leveling, without the need to dig planting trenches or create ridges, significantly reducing land preparation costs. Furthermore, the trays in this solution are reusable, reducing agricultural input costs.
[0018] 2) This device allows for the direct placement of 12-15cm flowerpots within the tray. Coconut coir is then placed inside the flowerpots, and tomato seedlings can be directly transplanted into them. Taking a 12cm flowerpot as an example, with a single pot volume of 0.6L and a density of 4 seedlings per square meter, the total volume of coconut coir used in a 1000 square meter greenhouse is 2400L. While meeting the needs of intercropping tomato production, the amount of coconut coir used is significantly less than that used in coconut coir strip planting and semi-hydroponics methods.
[0019] 3) This device fully considers the issues of fixing the base of the tomato plants and providing shade at the top after the plants have grown. After fixing the base with the plant fixing frame, all tomatoes grow in the same direction, preventing the tomato stems from leaning to one side or the other. In addition, a shade net is laid on the shade support frame (all top devices in the same planting row), which can block sunlight and reduce the root temperature in summer, and can retain heat and moisture in winter, promoting the absorption of nutrients by the roots.
[0020] 4) In large-scale planting, multiple sets of this device can be used in combination. On the one hand, it provides greater fixation and sturdiness; on the other hand, after each planting cycle, the flowerpots and plants can be directly removed for reuse. Furthermore, since the amount of coconut coir used in the flowerpots is small, the coconut coir in the flowerpots can be directly replaced after planting, reducing planting costs and eliminating the impact of soil or previous crop coconut coir on subsequent crops, completely preventing continuous cropping problems.

[0038] The method of using this utility model is as follows:
[0039] 1) After leveling the ground in the greenhouse, continuously lay the assembled trays 1 according to the planting density. The trays can be laid in a single row longitudinally or in two rows transversely. When laying, the two trays are connected and fixed with semi-circular buckles 12; 2) Place flower pots filled with coconut coir on the assembled trays 1. The diameter of the flower pots should be the same as the diameter of the pots in the planting troughs 11 of the assembled trays 1; 3) Lay the plant fixing frame 2 and adjust its direction to keep the two fixing holes 26 of the plant fixing frame 2 in the center of the two planting troughs 11 at the bottom; 4) Lay the drip irrigation pipe and insert the drip irrigation pipe into the open round hole in the plant fixing frame 2. 28.

[0040] In past planting practices, flower pots were mostly used for growing flowers, leafy vegetables, and other crops, with little experience in planting solanaceous crops. However, practical experience has shown that flower pots, on the one hand, can meet the needs of tomato crop rotation, and on the other hand, due to their low coconut coir content, can significantly improve the growth rate of the above-ground parts.
[0041] This invention abandons the traditional methods of land preparation, ridging, and digging planting trenches. It can be laid directly on the ground and the device can be reused, significantly reducing planting costs.
[0042] This invention fully considers the functions of irrigation and shading. On the one hand, it fixes the drip irrigation pipe to prevent it from tilting. On the other hand, it provides shade at the top, which can significantly reduce the root temperature in summer, preventing root absorption difficulties and the probability of blossom-end rot in tomatoes due to excessively high root temperatures. In addition, it can retain moisture and increase temperature in the roots in winter.
[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
