Description

Technical Field

[0001] This utility model relates to the field of tomato planting technology, specifically to a highly breathable seedling box for tomato planting. Background Technology

[0002] Tomato seedling cultivation is a crucial step in the industrialization of tomato planting. The health of the root system during the seedling stage directly affects the survival rate and later yield of the plants. Currently, traditional seedling boxes or seedling trays on the market are mainly divided into two structural categories: One type is the closed structure, where the side walls and bottom of the seedling cups or trays are continuous, non-porous plastic surfaces, with only a few small drainage holes at the very bottom. The advantage of this structure is its good moisture retention, but its fatal flaw is its extremely poor air permeability. The seedling substrate (soil, coconut coir) is in a moist and closed environment for a long time, making it difficult for the inside and outside air to exchange, which hinders root respiration and easily causes root hypoxia, leading to root rot and other phenomena. At the same time, because the inner wall of the box is not breathable, the roots cannot be pruned when they grow to the inner wall and can only grow spirally along the inner wall, forming a "root coiling" phenomenon, which is not conducive to later transplanting.

[0003] Another type is the semi-enclosed or open structure, which was developed to address the air permeability problem. For example, it involves creating more perforations in the side walls or using mesh materials. While this type of seedling box improves air permeability, it also introduces new problems, namely, the seedling substrate loses water too quickly. This not only increases the cost of manual maintenance, but also the drastic fluctuations in substrate moisture are detrimental to the stable growth of seedlings.

[0004] Therefore, this application proposes a highly permeable seedling box for tomato cultivation that can simultaneously achieve high air permeability and stable water retention, and synergistically solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the problems in the background technology, this utility model provides a highly breathable seedling box for tomato cultivation, which solves the technical contradictions in the prior art of poor air permeability of closed seedling boxes, easy root rot due to lack of oxygen, and rapid water loss and difficulty in stable humidity control of substrate in semi-closed seedling boxes.

[0006] A highly breathable tomato seedling box includes a ventilation trough, a water guide plate, seedling trays, and a top cover. The bottom of the ventilation trough is a water storage tray, and ventilation openings are provided on the side wall of the ventilation trough above the water storage tray. A support plate supporting the top cover is provided on the side wall of the ventilation trough above the ventilation openings. The ventilation trough is open above the support plate. The seedling trays are placed on the open opening of the ventilation trough. Several seedling cups are evenly distributed on the seedling trays. The lower ends of the seedling cups extend into the ventilation troughs and correspond to the ventilation openings. Long, narrow ventilation slots are evenly provided on the side walls of the seedling cups. The bottom of the seedling cups is provided with an inwardly convex water guide groove. The water guide plate is made of absorbent material and is placed inside the water storage tray. Several water guide strips inserted into the water guide grooves are integrally formed on the water guide plate. The top cover covers the seedling trays.

[0007] Furthermore, the width of the venting groove is 5-10mm.

[0008] Furthermore, the water guide plate has several through holes.

[0009] Furthermore, ventilation holes are provided on the side wall of the ventilation slot above the support plate, and insect-proof mesh is fixed on the ventilation holes.

[0010] Furthermore, the ventilation duct is equipped with a hanging device to facilitate off-ground cultivation.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves excellent lateral three-dimensional ventilation by opening air-permeable grooves on the side wall of the seedling cup and cooperating with the ventilation openings on the side wall of the ventilation groove, which solves the problem of root hypoxia in the closed seedling box and promotes the formation of a healthy root system with well-developed fibrous roots through the air trimming effect; at the same time, the automatic water supply system composed of the water storage tray and water guide plate at the bottom provides a continuous and stable water supply to the substrate, effectively solving the problem of easy drying and rapid water loss of the substrate in the semi-closed seedling box, and achieving high air permeability and high moisture retention.

[0012] 2. The water surface of the water storage tray and the aeration area of ​​the seedling cup are spatially isolated from each other, ensuring that the root zone obtains sufficient oxygen while the required water is precisely and continuously supplied from the bottom by the water guide strip. This avoids the substrate being too wet or too dry, creating an ideal seedling microenvironment of "dry and breathable at the top, and moist at the bottom to promote root growth", reducing the probability of diseases such as root rot.

Detailed Implementation

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] Please see Figures 1 to 5 This utility model proposes a highly breathable tomato seedling box, including a ventilation trough 1, a water guide plate 2, seedling trays 3, and a top cover 4. The ventilation trough 1 is the base of the entire seedling box, and its bottom is integrally formed into a water storage tray 11. On the side wall of the ventilation trough 1 above the water storage tray 11, one or more ventilation openings 12 are opened around the side wall. The ventilation openings 12 are the key structure for achieving lateral ventilation. Above the ventilation openings 12, a ring of outwardly extending support plates 13 is provided on the outer wall of the ventilation trough 1 to stably support the top cover 4. The seedling trays 3 are placed on the open top of the ventilation trough 1, and several seedling cups 31 are distributed in an array on the seedling trays 3. like Figure 5 As shown, when the seedling tray 3 is placed in place, the lower half of each seedling cup 31 extends into the interior of the ventilation groove 1, and its position is at the same level as the ventilation opening 12 on the side wall of the ventilation groove 1, so that outside air can be blown directly onto the side wall of the seedling cup 31 through the ventilation opening 12. In order to achieve further air penetration, several vertical elongated air vents 32 are evenly opened on the side wall of each seedling cup 31. In this embodiment, the width of the air vents 32 is preferably set to 5-10mm. This size can ensure excellent air permeability and effectively prevent the seedling substrate from falling out of the holes. The bottom of the seedling cup 31 is not flat, but is provided with an upwardly convex water guide groove 34. The water guide groove 34 is used to connect with the water guide plate 2 for water transfer.

[0018] See Figure 2 , Figure 3The water guide plate 2 is made of sponge, absorbent cotton or other materials with good capillary water absorption properties and is placed directly in the water storage tray 11. The upper surface of the water guide plate 2 is integrally formed with several upward upright water guide strips 21, the number and position of which correspond one-to-one with the water guide grooves 34 on the seedling tray 3. When the seedling tray 3 is placed, the top of each water guide strip 21 is inserted into the water guide groove 34 at the bottom of the corresponding seedling cup 31 and in contact with the seedling substrate. In order to enhance the overall water absorption and permeability uniformity of the water guide plate 2 and enhance the environmental humidity, several through holes can also be opened on the plate body of the water guide plate 2.

[0019] See Figure 4 The top cover 4 is made of transparent or semi-transparent material, which makes it easy to observe the growth of the seedlings inside. The top cover 4 covers the seedling tray 3 and is placed firmly on the tray 13 of the ventilation duct 1 to form a closed or semi-closed space for heat preservation and moisture retention in the early stage of seedling cultivation. In order to ventilate while keeping the soil moist, ventilation holes 14 are provided on the side wall of the ventilation duct 1 above the tray 13, that is, in the area covered by the top cover 4. Insect-proof mesh is covered on the ventilation holes 14 to prevent pests from entering.

[0020] To facilitate hanging and off-ground cultivation, the sides of the ventilation duct 1 are integrally formed or equipped with hanging components 5. The hanging components 5 can be as follows: Figure 1 The lifting ring structure shown can also be a hook or other structure.

[0021] Work process: When using, first pour an appropriate amount of water into the water storage tray 11 at the bottom of the ventilation slot 1. The water level should not be too high, so that it does not directly contact the bottom of the seedling cup 31. Then, put the water-absorbing material guide plate 2 into the water storage tray 11 to allow it to fully absorb water. Next, place the seedling tray 3 containing the seedling substrate and tomato seeds on the ventilation slot 1, ensuring that the water guide groove 34 at the bottom of each seedling cup 31 is correctly aligned with the water guide strip 21 on the water guide plate 2 and that the water guide strip 21 is in contact with the substrate. At this time, water will be continuously and automatically transported to the seedling substrate through the capillary action of the water guide strip 21. Finally, cover the top cover 4. During the seedling process, fresh air from the outside can enter the seedling box laterally through the ventilation opening 12 on the side wall of the ventilation slot 1, and pass through the ventilation slot 32 on the side wall of the seedling cup 31 to directly provide oxygen to the roots of the tomato seedlings, while removing excess moisture, thus forming a highly permeable root zone environment.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
