A new type of rice seedling tray

Abstract

This utility model belongs to the field of seedling tray technology, specifically a novel rice seedling tray, including a main structure. Within the main structure are arrayed slots, separated by partitions. Each slot has a drainage hole at its bottom, and radial grooves radiating outwards from the drainage hole. A baffle is located below the main structure, with circular holes corresponding to the drainage holes. A strip-shaped connecting plate passes through the baffle, corresponding to the partitions along the length of the main structure. When placed on the ground during planting, this seedling tray allows the main structure to be in a supported position, resulting in faster drainage. The space at the bottom of the main structure prevents rice roots from growing randomly after contacting air, minimizing root cross-contamination. The partitions, connecting plates, and baffles enhance the strength of the seedling tray and prevent deformation.

Description

Technical Field

[0001] This utility model belongs to the field of seedling tray technology, specifically a new type of rice seedling tray. Background Technology

[0002] Existing rice seedling trays mostly adopt a one-piece molded trough structure with drainage holes at the bottom for water and air permeability. However, this type of structure has obvious defects in practical use: First, the tray structure is not strong enough and is prone to deformation when reused or stacked, affecting its service life and operational efficiency; second, the roots of adjacent seedlings are prone to intertwining, resulting in severe root damage and poor seedling integrity when harvesting seedlings, making it difficult to meet the requirements of mechanized rice transplanting; in addition, when traditional seedling trays are placed in the seedbed, the drainage holes are often in direct contact with the soil and are easily blocked, causing poor drainage, root hypoxia, and thus affecting the normal growth of seedlings.

[0003] Therefore, there is an urgent need for a rice seedling tray with a stable structure that can effectively prevent root cross-growth and has good drainage performance. Utility Model Content

[0004] Based on this, this solution provides a new type of rice seedling tray with a baffle at the bottom, which can maintain a certain gap between the entire main structure and the soil below, making the rice less prone to oxygen deficiency and providing good drainage performance. It can also achieve the effect of air root pruning, and together with the baffle, it can prevent root cross-contamination.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A novel rice seedling tray includes: a main structure, wherein a grid-like partition is provided inside the main structure, dividing the internal space of the main structure into several planting troughs arranged in an array. Each planting trough has a drainage hole at its bottom, and a groove is provided around the drainage hole. A baffle is provided below the main structure, the baffle is parallel to the bottom of the main structure and is fixedly connected to the main structure. A through circular hole is provided on the baffle at the position corresponding to the drainage hole, and a downwardly extending protrusion is provided at the bottom of the baffle.

[0007] Optionally, in one embodiment of the present invention, the groove is a strip-shaped structure, radially formed on the inner bottom surface of the planting trough with the drainage hole as the center.

[0008] Optionally, in one embodiment of the present invention, the top edge of the main structure is provided with an outwardly extending flange to facilitate stacking and retrieval.

[0009] Optionally, in one embodiment of this utility model, the main structure is an inverted trapezoidal structure, which facilitates the stacking of seedling trays.

[0010] Optionally, in one embodiment of the present invention, the top of the partition is provided with a semi-circular opening.

[0011] Optionally, in one embodiment of the present invention, the protrusion is a grid-like structure for more stable placement in the soil.

[0012] Optionally, in one embodiment of the present invention, the protrusion is a cylindrical structure for more stable placement in the soil.

[0013] Compared with the prior art, the novel rice seedling tray provided by this utility model has the following characteristics:

[0014] A baffle is installed at the bottom of the main structure. The baffle is fixedly connected to the bottom of the main structure, so that the main structure is in a suspended state, forming an air gap in the middle. This can prevent the drainage holes from being blocked, maintain air circulation at the bottom of the main structure, prevent the seedlings from rotting, allow the roots of the seedlings to come into contact with the air as they grow downwards, achieve the effect of air-root pruning, and ensure the structural strength of the seedling tray to prevent deformation.

[0015] The grooves within the planting trough accelerate drainage and, in conjunction with the drainage holes and the raised layer, enable air-based root trimming. This promotes stronger root development in the seedlings, making them less prone to breakage during harvesting, suitable for machine transplanting, improving transplanting efficiency and quality, and ensuring uniformity in planting.

[0016] The partitions not only separate the planting troughs, but also allow for quick separation and removal of seedlings, preventing the roots of seedlings from intertwining in adjacent troughs. Attached Figure Description

[0025] Example 1

[0026] Because existing rice seedling trays have a simple structure, insufficient strength, and are prone to deformation, and lack internal isolation structures, they are susceptible to root cross-contamination, which is detrimental to subsequent mechanical operations. Therefore, a new type of rice seedling tray has been designed, and the specific solution is as follows:

[0027] like Figure 1-4 As shown, a novel rice seedling tray includes: a main structure 1, with a grid-like partition 2 inside the main structure 1, dividing the internal space of the main structure 1 into several planting troughs 102 arranged in an array by the partition 2, with a drainage hole 103 at the bottom of each planting trough 102, and grooves 104 around the drainage hole 103, and a baffle 3 at the bottom of the main structure 1, which is parallel to the bottom of the main structure 1 and fixedly connected to the main structure 1, with a through circular hole 301 on the baffle 3 corresponding to the position of the drainage hole 103, and a downwardly extending protrusion 4 at the bottom of the baffle 3.

[0028] The baffle 3 creates an air-filled barrier between the bottom of the seedling tray and the ground. This facilitates air circulation at the bottom of the seedling tray structure 1, preventing root rot and regulating local humidity to some extent. It also ensures that the drainage hole 103 is in a drainable state, preventing the root environment from becoming suffocated due to the tray bottom being in contact with the ground. The barrier allows for better air-based root pruning.

[0029] The groove 104 is a strip-shaped structure, radiating outwards from the drainage hole 103 on the inner bottom surface of the planting trough 102. The groove 104 accelerates drainage, and when the roots reach the end of the groove 104 and come into contact with air, the root tips stop growing, allowing secondary lateral roots to grow inside the planting trough 102. This increases the overall number and vitality of the roots, forming a root ball, which is beneficial for seedling harvesting and machine transplanting.

[0030] The top edge of the main structure 1 is provided with an outwardly extending flange 101 to facilitate stacking and retrieval, and also to improve the strength of the top edge of the main structure 1 and prevent deformation.

[0031] The main structure 1 has an inverted trapezoidal structure, which facilitates the stacking of seedling trays.

[0032] The top of the partition 2 has a semi-circular opening 201, which can keep the water level uniform among the planting troughs 102.

[0033] In this embodiment, the protrusion 4 is a grid-like structure, which can stably place the entire seedling tray on the soil.

[0034] Structural Description:

[0035] The bottom baffle 3 ensures that the drainage hole 103 is unobstructed, reducing the risk of the drainage hole 103 being blocked. The bottom air layer can effectively supply oxygen to the roots and avoid the problem of root rot. When the roots grow downward and penetrate the drainage hole 103 and come into contact with dry air, the root tip will naturally stop elongating. This will stimulate the seedlings to sprout more lateral roots and fibrous roots in the planting trough 102, forming a root ball. This helps prevent the seedlings from falling apart when taking them out during machine transplanting, improving the quality and efficiency of the operation.

[0036] The groove 104 provides additional drainage channels, allowing water to flow to the drainage hole 103 more quickly, preventing local water accumulation in the planting trough 102. As the roots grow in the trough, air pruning occurs once they reach the end of the groove 104 and come into contact with air.

[0037] The opening 201 on the partition 2 allows the water level between each planting trough 102 to circulate and remain consistent during irrigation, resulting in more uniform water and fertilizer management and higher uniformity of growth for the seedlings.

[0038] The rice seedling tray of this design has a baffle 3 at the bottom of the main structure 1 to form an air gap, which prevents the drainage holes 103 from being blocked, promotes air circulation at the bottom, prevents root rot, achieves the effect of air root trimming, and ensures the structural strength of the seedling tray to avoid deformation.

[0039] The groove 104 inside the planting trough 102 accelerates drainage and, in conjunction with the drainage hole 103 and the elevated layer, enables air-based root trimming. This promotes more developed seedling roots, making them less prone to breakage during harvesting, suitable for machine transplanting, improving transplanting efficiency and quality, and ensuring uniformity in transplanting.

[0040] The partition 2 can separate the planting troughs 102 and prevent the roots of seedlings in adjacent planting troughs 102 from getting tangled.

[0041] Example 2

[0042] In this embodiment, the structure of the rice seedling tray is basically the same as that of Embodiment 1. The difference is that the protrusion 4 is a cylindrical structure, which is more stable in the soil. The cylindrical structure is located at the intersection and both ends of the original grid structure, so that it acts like a support column and is inserted into the soil to stabilize the seedling tray.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
