Description

Technical Field

[0001] The utility model relates to a structure of a rice seedling tray, in particular to a water-saving industrialized rice seedling tray. Background Art

[0002] In the process of rice planting, it is first necessary to raise seedlings, and then carry out manual transplanting or mechanical transplanting. There are many ways to raise seedlings, and some use seedling trays. The currently commonly used seedling tray is a square frame structure, and the bottom of the square frame is densely distributed with water seepage holes. When raising seedlings, the substrate is filled into the seedling tray, seeds are scattered, and then the substrate is used to cover the seeds. During the seedling raising process, watering is often required to promote the seeds to take root and germinate.

[0003] Although the substrate in the seedling tray has a certain water retention capacity, due to the dense distribution of water seepage holes at the bottom of the seedling tray, a large amount of water sprayed will directly flow out through the water seepage holes. In order to ensure that the substrate is within a certain humidity range, it is necessary to spray water frequently, which will undoubtedly cause waste of water resources and is also laborious and power-consuming.

[0004] At the same time, since the current seedling tray does not have the ability to store water, there will inevitably be an uneven watering situation when spraying water on the seedling tray, which will result in different water contents of the substrate in different areas of the seedling tray, thus causing differences in the growth of the seedlings. At the same time, due to the lack of water storage capacity of the seedling tray, the growth of the seedlings is easily affected by temperature. Summary of the Invention

[0005] The purpose of the utility model is to provide a water-saving industrialized rice seedling tray. By setting water seepage holes higher than the bottom surface, the seedling tray has a certain water storage capacity, improves the water utilization rate, reduces the irrigation frequency, and can achieve the effects of saving water, labor and electricity, etc.

[0006] The technical solution of the utility model: A water-saving industrialized rice seedling tray includes a seedling tray bottom plate, a seedling tray frame is fixedly connected to the edge of the surface of the seedling tray bottom plate, columns higher than the seedling tray bottom plate are densely arranged on the surface of the seedling tray bottom plate, and water seepage holes penetrating the seedling tray bottom plate and the columns are vertically arranged in the columns, and the height of the columns is 1 / 3 - 2 / 3 of the height of the seedling tray frame.

[0007] In the foregoing water-saving industrialized rice seedling tray, multiple reinforcing pieces are fixedly arranged on the outer wall of each column, and the bottom of the reinforcing pieces is fixedly connected to the surface of the seedling tray bottom plate.

[0008] In the foregoing water-saving industrialized rice seedling tray, multiple vertical water seepage grooves are uniformly arranged on the inner wall of the water seepage holes.

[0009] In the foregoing water-saving industrialized rice seedling tray, a flange plate extending outward is arranged at the top edge of the seedling tray frame.

[0010] In the aforementioned water-saving factory rice seedling tray, the inner and outer sides of the tray frame are both conical structures that gradually converge downward.

[0011] In the aforementioned water-saving factory rice seedling tray, the tray bottom plate, the tray frame, the columns, and the reinforcement pieces are of an integrally formed structure.

[0012] Advantages of the present utility model: Compared with the prior art, the present utility model has the following advantages:

[0013] 1. Seepage holes higher than the tray bottom plate are formed, and the water poured into the seedling tray will not be discharged until it reaches the storage upper limit of the seedling tray, having a certain water storage capacity, improving the water utilization rate, reducing the number of irrigation times, and achieving the effects of water saving, labor saving, and power saving.

[0014] 2. In the case of uneven sprinkler irrigation in the same seedling tray, the water in the area with more irrigation will flow to the area with less irrigation after the moisture in the seedling-growing substrate reaches saturation, ensuring that the seedling-growing substrates in the same seedling tray all quickly reach moisture saturation and store a certain amount of water.

[0015] 3. When the water consumption of the same seedling tray is different, the area with less water consumption can supply water to the area with more water consumption, which can avoid the difference in the growth of seedlings in the same seedling tray due to the difference in water consumption and improve the seedling emergence rate of the seedlings.

[0016] 4. Since the specific heat capacity of water is greater than that of the seedling-growing substrate, the increase in the water storage capacity of the seedling tray can indirectly increase the heat preservation effect of the seedling tray. When the temperature rises in hot weather, the temperature rise speed of the whole seedling tray can be slowed down, and when the temperature drops in cold weather, the temperature drop speed of the whole seedling tray can be slowed down, which is more conducive to the growth of seedlings.

[0022] The following further describes the present utility model in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for restricting the present utility model.

[0023] Embodiment of the present utility model: A water-saving factory rice seedling tray, which includes a seedling tray bottom plate 1. A seedling tray border 2 is fixedly connected to the surface edge of the seedling tray bottom plate 1. The surface of the seedling tray bottom plate 1 is densely covered with upright columns 3 that are higher than the seedling tray bottom plate 1. A water seepage hole 4 that penetrates the seedling tray bottom plate 1 and the upright column 3 is vertically arranged in the upright column 3. The vertical arrangement structure of the water seepage hole 4 is convenient for processing. The height of the upright column 3 is 1 / 3 to 2 / 3 of the height of the seedling tray border 2. If the height is too low, the water storage capacity is small, and the stored water is quickly consumed, and high-frequency irrigation is still required, and the water-saving benefit is not obvious; if the height is too high, the water storage capacity is large, and the seedling-growing substrate is in a saturated water content state for too long. Due to the characteristics of "wet leaves and dry roots" of rice seedlings, it is not conducive to the growth of seedling roots. At the same time, the growth of seedling leaves is too lush, and the survival rate after transplantation is reduced.

[0024] The seedling tray border 2 and the seedling tray bottom plate 1 of the present utility model form the outer shell of the seedling tray, which is used to fill the substrate, seedlings and water. The water seepage hole 4 stands vertically on the seedling tray bottom plate 1, and the top surface of the water seepage hole 4 is lower than the top surface of the border. When watering, the water poured into the seedling tray is first absorbed by the seedling-growing substrate. After the seedling-growing substrate absorbs water to saturation, the irrigation water can be stored in the space below the plane where the top surface of the water seepage hole 4 is located and above the seedling tray bottom plate 1, and has a certain water storage capacity. When the stored water level is higher than the top surface of the water seepage hole 4, the water is discharged from the seedling tray through the water seepage hole 4.

[0025] Multiple reinforcing pieces 5 are fixedly connected to the outer wall of each upright column 3. The bottom of the reinforcing piece 5 is fixedly connected to the surface of the seedling tray bottom plate 1. The connection between the upright column 3 and the seedling tray bottom plate 1 can be strengthened through the reinforcing piece 5, and the situation of the upright column 3 breaking can be avoided.

[0026] A plurality of vertical water seepage grooves 6 are uniformly arranged on the inner wall of the water seepage hole 4. The purpose of setting the water seepage grooves 6 is to avoid water being discharged through the water seepage grooves 6 when the water seepage hole 4 is blocked by the substrate being compacted. The size of the water seepage grooves 6 is smaller than that of the water seepage hole 4. Generally, the substrate is in the form of millimeter-sized particles, and these particles can fall into the water seepage hole 4 and may even block the water seepage hole 4, but these particles are not easy to enter the small water seepage grooves 6 and are even less likely to block the water seepage grooves 6, thus ensuring the drainage capacity of the seedling tray. The vertical arrangement of the water seepage grooves 6 is also for the convenience of production and processing.

[0027] A flange plate 7 that extends outwards is arranged at the top edge of the seedling tray border 2. When carrying out seedling-growing operations in the factory, the flange plate 7 facilitates the overall placement of the seedling tray on the seedling-growing rack, so that multiple seedling trays can be placed in space on one seedling-growing rack.

[0028] Both the inside and outside of the seedling tray border 2 are conical structures that gradually converge obliquely downwards, as Figure 4As shown, it is convenient to stack multiple seedling trays together, while reducing the space occupied during stacking, facilitating storage and handling.

[0029] The seedling tray bottom plate 1, the seedling tray frame 2, the upright column 3 and the reinforcing piece 5 are of an integrally formed structure, which is convenient for factory processing and can reduce processing costs.
