Description

Technical Field

[0001] The present invention relates to the technical field of vegetable seedling cultivation, and in particular to a device for vegetable seedling cultivation with intelligent precision water supply by partitioning and a seedling cultivation method thereof. Background Art

[0002] Vegetable seedling cultivation refers to the technical process of cultivating strong seedlings through artificially controlled conditions during the vegetable planting process. This process is crucial to improving the efficiency and quality of vegetable production.

[0003] In the prior art, vegetable seedling cultivation includes two mainstream methods, namely, plug tray seedling cultivation and floating tray seedling cultivation. The main difference between the two seedling cultivation methods is that the seedling watering methods are different. Among them, plug tray seedling cultivation relies on manual or micro-sprinkler irrigation to water the seedlings, which requires a large amount of labor. Especially in the case of large-scale seedling cultivation and seedling cultivation in high temperature weather, the labor cost is higher, and the watering amount of each tray of seedlings cannot be guaranteed to be consistent, and there is also a problem of wasting water resources; while floating tray seedling cultivation uses water from the seedling cultivation pool to supply water to the seedlings. Since the seedling cultivation foam tray is always floating in the water, it is not conducive to the growth of the seedling root system, and once the entire seedling cultivation pool is diseased, all the seedlings are at risk of getting sick. In addition, the water supply methods of plug tray seedling cultivation and floating tray seedling cultivation have the problem of increasing humidity and the probability of disease, especially in low temperature weather, the probability of seedlings getting sick is greatly increased, which reduces the success rate of vegetable seedling cultivation to a certain extent. Therefore, the present invention proposes a device for vegetable zoned intelligent precision water supply seedling cultivation and a seedling cultivation method thereof to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to propose a device for vegetable zoned intelligent precision water supply seedling cultivation and a seedling cultivation method thereof, so as to solve the problems that the existing hole tray seedling cultivation method has high labor costs, cannot ensure consistent watering amount for each tray of seedlings, wastes water resources, and the existing floating tray seedling cultivation is not conducive to the growth of the root system of vegetable seedlings and has a high probability of vegetable seedlings getting sick.

[0005] In order to achieve the purpose of the present invention, the present invention is implemented through the following technical scheme: a device for intelligent precision water supply for vegetable seedling cultivation in different zones, comprising a seedling bed, water storage trays symmetrically placed at the top of the seedling bed and distributed at equal intervals, seedling plug trays are embedded on the water storage trays, a water supply main is provided on the front side of the seedling bed, an intelligent irrigation control valve is installed on the water supply main, a first water main placed on the top of the seedling bed is fixed to the top of the water supply main, a second water main placed on the top of the seedling bed is symmetrically fixed on one side of the first water main close to the water storage tray, water distribution pipes penetrating into the water storage tray are equidistantly fixed on the opposite sides of two groups of the second water mains, and independent electronic control valves are installed on the water distribution pipes.

[0006] A further improvement is that support plates are equidistantly arranged below the seedling bed, universal wheels are symmetrically fixed to the bottom ends of the support plates, and support columns are equidistantly fixed between the support plates and the seedling bed.

[0007] A further improvement is that an engaging groove is opened in the middle of the front side of the seedling bed, the water supply main pipe is placed in the engaging groove, and the end of the water supply main pipe away from the first water transmission main pipe is connected to an external water supply device.

[0008] A further improvement is that a groove hole is opened on the side wall of the water storage tray close to the second water main pipe, and the end of the water distribution pipe away from the second water main pipe passes through the groove hole to the inside of the water storage tray.

[0009] A further improvement is that: the seedling raising hole tray is provided with seedling raising hole grooves distributed in an array, and the bottom ends of the seedling raising hole grooves are provided with water seepage holes.

[0010] A further improvement is that the water storage tray and the seedling hole tray have the same length, width and height, and the seedling hole tray is supported by the edge of the water storage tray when it is placed on the water storage tray.

[0011] A seedling raising method of a device for raising seedlings of vegetable zoning intelligent precision water supply comprises the following steps:

[0012] Step 1: First, open the intelligent irrigation control valve on the water supply main pipe, so that the irrigation water in the external water supply equipment is injected from the water supply main pipe into the first water delivery main pipe, and then injected from the first water delivery main pipe into the second water delivery main pipe. Then, open the independent electronic control valve on the water distribution pipe, so that the irrigation water in the second water delivery main pipe is injected into the water storage tray through the water distribution pipe. Then, close the intelligent irrigation control valve and the independent electronic control valve to stop water injection.

[0013] Step 2: Sow the vegetable seeds to be cultivated in the seedling tray, and then place the seedling tray on the water storage tray. After the vegetable seeds germinate and grow seedlings, open the intelligent irrigation control valve and the independent electronic control valve according to the growth stage of the vegetable seedlings, so as to supply water to the water storage tray regularly and quantitatively, so as to irrigate the vegetable seedlings in the seedling tray.

[0014] A further improvement is that in step 1, the depth of the irrigation water injected into the water storage tray is one third of the depth of the water storage tray.

[0015] The beneficial effects of the present invention are as follows: the present invention controls the water supply main pipe to supply water to the first water delivery main pipe and the second water delivery main pipe in a quantitative and regular manner through the intelligent irrigation control valve, and controls each water branch pipe to supply water to the corresponding water storage tray through each independent electronic control valve, so that the water storage tray can store water intelligently and accurately, and the water requirement of the vegetable seedlings in the seedling hole tray is guaranteed from the root, which is beneficial to the root growth of the vegetable seedlings, is not prone to diseases, and can also reduce the number of watering times for the vegetable seedlings, save labor and labor expenses, and will not cause waste of water resources;

[0016] And it can accurately add water according to the water requirements of different vegetable seedlings and different growth stages in the seedling tray, which can meet the water requirements of different vegetable types and growth stages. At the same time, the seedling tray is placed in the water storage tray in a mosaic plug-in manner, and each pipeline is placed on the seedling bed. The overall structure of the device is simple, the installation is convenient, and it is easy to operate. It can be installed once and can be used for many years. The seedling tray and the water storage tray can also be used repeatedly for many years, which reduces the cost of the device and the cost of seedling cultivation to a certain extent.

[0017] The present invention combines the advantages of traditional plug tray seedling cultivation and floating tray seedling cultivation, and achieves multiple goals of water saving, energy saving, disease prevention and growth promotion in the seedling cultivation process by accurately and automatically controlling the water supply of each seedling tray and combining it with a zoning management strategy.
