Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant cultivation, and in particular to a plant whole growth cycle regulation system and method. BACKGROUND

[0002] Plant breeding is a technology for improving the genetic characteristics of crops to cultivate high-yield and high-quality varieties. Shortening the growth cycle of crops and accelerating the speed of generation of pure lines are important ways to improve breeding efficiency. The existing technology has made a lot of improvements to the culture equipment used for plant breeding in order to shorten the breeding time by providing nutrients required for plant growth in a timely manner.

[0003] For example, Chinese Patent No. CN111565562A discloses a hydroponic device, which includes a grow bed tray having a base and at least two side walls and an atomizer for atomizing a nutrient solution, the grow bed tray being capable of holding a plant support at a position spaced apart from the base of the grow bed tray, the atomizer being located at the base of the grow bed tray and including an ultrasonic transducer and a holder for holding the ultrasonic transducer. The patent also discloses a method for producing crops using the hydroponic device, which causes the nutrient solution to flow into the base of the grow bed tray to at least contact the roots of the crops, or provides the nutrient solution at the base of the grow bed tray and atomizes the nutrient solution, so that the atomized nutrient solution at least contacts the roots of the crops.

[0004] Chinese Patent No. CN110178717A discloses a fully sealed plant nutrient hydroponic device and a plant hydroponic method thereof. In the technical solution adopted in the patent, the hydroponic device includes a hydroponic box, a cultivation plate separates the hydroponic box into a photosynthetic hydroponic box and a rhizosphere hydroponic box, and provides different nutrient mists required by stems and leaves and rhizosphere respectively, and collects and reuses them separately. The invention sets up a one-way circulation mode and a complete internal circulation mode which can be freely switched. The one-way circulation mode can realize the entry of purified air and the utilization of carbon dioxide generated by stems and leaves to rhizosphere. The complete internal circulation mode can realize the transportation of carbon dioxide generated by roots to plant stems and leaves to accelerate photosynthesis, and the transportation of oxygen generated by photosynthesis of stems and leaves to roots for respiration.

[0005] Chinese Patent No. CN114766346A discloses a vegetable seedling hydroponic device for agricultural planting, which includes a seat body, a hydroponic box is arranged on the outer wall of the seat body, a supporting mechanism is arranged on the inner wall of the hydroponic box, a hydroponic plate is arranged at the end of the supporting mechanism, a plurality of rows of hydroponic openings are arranged on the outer wall of the hydroponic plate, a vertical rod is arranged at each of the four corners of the outer wall of the seat body, an installation plate is arranged at the end of the vertical rod, a liquid storage tank is arranged on the outer wall of the installation plate, a liquid guide pipe is arranged on the outer wall of the liquid storage tank, a dropper is arranged on one side of the outer wall of the liquid guide pipe, and a piston is connected to the outer wall of the hydroponic plate through a fixing rod.

[0006] In the existing air mist cultivation method, although the atomized nutrient solution can cover the plant range, since the atomized nutrient solution is not all absorbed by the plant, there is a large deviation between the atomized amount of the nutrient solution and the actual absorption amount of the plant. In order to ensure the smooth growth of the plant, the actual use amount of the nutrient solution is greater than the actual absorption amount of the plant. In addition, the required nutrient components are different in different growth stages of the plant growth cycle. How to accurately apply the required component nutrient solution to the plant in different growth stages is a problem to be solved in plant cultivation.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when making the present application, but due to the limitation of space, all details and contents have not been listed in detail. However, this does not mean that the present application does not have these prior art characteristics. On the contrary, the present application already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0008] In view of the deficiencies of the prior art, the present application provides a plant full growth cycle regulation system, which comprises a planting device for accommodating the root growth of a plant. The regulation system further comprises a mist culture unit, a water culture unit, a data processing unit, a data storage unit and a sensing unit. Preferably, the mist culture unit is used to spray nutrient solution to the roots of the plant. Preferably, the water culture unit is used to adjust the proportion of the roots of the plant immersed in the nutrient solution. Preferably, the data storage unit is configured to at least pre-store growth data of one or more plants, wherein the growth data can include root morphology in different growth stages of the plant full growth cycle, proportion of mist culture environment and water culture environment adapted to the plant root morphology, and root morphology of the plant when the nutrient solution lacks a certain component. Preferably, the sensing unit is used to at least obtain plant root morphology data. Preferably, the data processing unit is configured to generate a control instruction for adjusting the working parameters of the mist culture unit and the water culture unit according to the plant root morphology data obtained by the sensing unit and the plant growth data pre-stored in the data storage unit to adjust the growth environment parameters of the plant roots in the planting device.

[0009] Preferably, the present application adopts a cultivation method combining fog culture and water culture, and the plant root system is partially immersed in the water culture nutrient solution in which nutrients are dissolved, and the part of the atomized nutrient solution that is not absorbed by the plant can condense into the water culture nutrient solution, solving the problem that the atomized nutrient solution cannot be completely absorbed by the plant root system, and improving the efficiency of the plant in absorbing, transporting and utilizing nutrients. Preferably, the present application can obtain the growth data of the plant, such as the root morphology of the plant at different growth stages in the whole growth cycle, the data relationship between the fog culture environment and the water culture environment adapted to the root morphology of the plant, and the root morphology of the plant when the nutrient solution lacks a certain component, and store the growth data. Preferably, during the cultivation of the plant, the present application can determine the growth environment requirement of the plant root by comparing the monitored root morphology of the plant with the growth data, and then adjust the growth environment parameters of the plant root to build an environment suitable for the growth of the plant, so as to accurately supply the nutrient solution containing the required components to the plant at different growth stages, make the supply amount of the nutrient solution more suitable for the actual growth process of the plant, and improve the efficiency of the nutrient solution.

[0010] According to a preferred embodiment, the data processing unit determines the growth stage and growth condition of the plant according to the plant root morphology data, and generates adjustment parameters for adjusting the working parameters of the fog culture unit and / or the water culture unit to adjust the growth environment parameters of the plant root according to the growth stage and growth condition of the plant.

[0011] Preferably, the present application uses the plant root morphology data as the basis for determining the growth stage and growth condition of the plant, which can detect the change of the growth stage and / or growth condition of the plant earlier than the method of determining the growth stage and growth condition of the plant according to the morphology of the above-ground part of the plant such as branches, leaves, etc. Compared with the change of the morphology of the above-ground part of the plant, the change of the morphology of the root system of the plant runs through the whole cycle of the growth and development of the plant. In particular, for plants such as potatoes, radishes, taros and ginseng that produce substances from underground rhizomes, the difference in root morphology at different growth stages and / or growth conditions is more obvious than the difference in the morphology of the above-ground part of the plant, which is conducive to distinguishing and reducing the data processing amount of image recognition and other work.

[0015] The nutrient composition required by the plant is different when the growth stage or the growth condition of the plant is different. Compared with the method of using a single nutrient solution for the whole cycle of plant cultivation, the present application provides a nutrient solution that adapts to the growth needs of the plant after determining the growth stage or the growth condition of the plant, which is beneficial to promote the growth of the plant. In particular, when breeding, the plant is provided with an adapted nutrient solution according to the growth stage or the growth condition of the plant, so as to promote the growth of the plant in the whole growth cycle of the plant, which is beneficial to explore the limit of the fastest maturation of the plant.

The present application can determine the way to adjust the proportion of the roots of the plant immersed in the nutrient solution according to the root morphology of the plant, so as to avoid damaging the root system of the plant or causing waste of the nutrient solution. For example, when the root system of the plant is not developed, the hydroponic unit adjusts the proportion of the roots of the plant immersed in the nutrient solution by adjusting the distance between the root system of the plant and the bottom of the planting device, so as to reduce the use of the nutrient solution.

[0018] According to a preferred embodiment, the data processing unit can also adjust the aeroponic range and the spraying frequency of the aeroponic unit in the planting device according to the current growth stage and growth condition of the plant, so that the absorption capacity of the root system of the plant is adapted to the atomized nutrient solution.

[0019] Preferably, the present application adjusts the misting range and spraying frequency of the misting unit according to the current growth stage and growth condition of the plant, so that the misting range of the misting unit covers the root system of the plant and sprays the nutrient solution to the root system as much as possible, reduces the amount of condensed nutrient solution after atomization, and improves the effective atomization amount of the misting unit.

[0020] According to a preferred embodiment, the data processing unit sends a third control instruction for treating the plant diseases and pests to the misting unit when the sensing unit detects plant diseases and pests. The misting unit atomizes the pesticide for treating the corresponding plant diseases and pests in response to the third control instruction and releases the atomized pesticide through the atomizing nozzle arranged in the plant disease and pest area.

[0021] Preferably, compared with the whole administration mode, the present application can release the pesticide for treating plant diseases and pests to the disease area through the misting unit, accurately treat the plant diseases and pests, reduce the amount of pesticide, and improve the treatment efficiency.

[0022] According to a preferred embodiment, the growth stage at least includes a seedling stage, a development stage, and a mature stage. The growth condition at least includes a normal growth condition and an abnormal growth condition of the plant under at least one lack of fertilizer.

[0023] Preferably, the present application can collect the growth data of the plant under the condition of lacking one or more fertilizers and the growth data of the plant in different growth stages and store the collected growth data in the data storage unit, so that in the subsequent cultivation process of the same plant, the current growth data of the plant can be compared with the stored growth data to determine which component is lacking in the current nutrient solution relative to the growth needs of the plant, and then the composition of the nutrient solution is adjusted so that the composition of the nutrient solution can meet the growth needs of the plant.

[0024] The present application also provides a plant whole growth cycle cultivation method. The cultivation method at least includes: obtaining plant root system morphology data; determining the current growth stage and growth condition of the plant according to the plant root system morphology data; determining the nutrient solution composition and the proportion of the plant root system immersed in the nutrient solution according to the current growth stage and growth condition of the plant; misting and hydroponic cultivating the plant.

[0025] Preferably, the present application adopts a cultivation method combining fog culture and water culture, and the plant root system is partially immersed in the water culture nutrient solution in which nutrients are dissolved, and the part of the atomized nutrient solution that is not absorbed by the plant can condense into the water culture nutrient solution, solving the problem that the atomized nutrient solution cannot be completely absorbed by the plant root system, improving the efficiency of the plant in absorbing, transporting and utilizing nutrients, and the present application adjusts the proportion of the plant root system between the nutrient solution and the spray to avoid the plant from rotting. According to a preferred embodiment, the regulation method further comprises: adjusting the type of nutrient solution used in fog culture and / or water culture to adjust the composition of the nutrient solution when the growth stage of the plant changes or the growth condition is abnormal.

[0026] Preferably, the present application adjusts the composition of the nutrient solution according to the change of the growth stage and the growth condition, so as to accurately apply the nutrient solution with the required composition of the plant in the whole growth cycle of the plant.

After the nutrient solution preparation module prepares the nutrient solution with the relative proportions of nitrogen, phosphorus and potassium being 56%, 48.5% and 49% respectively, the aeroponics unit 120 and the hydroponics unit 130 input the nutrient solution suitable for the development stage of the potato into the planting device 110.

[0064] Preferably, the data processing unit 140 determines the current growth condition of the plant according to the root system morphology data of the plant obtained by the root system morphology sensor 162. If the current growth condition of the plant is consistent with the growth condition of the plant under the condition of lacking one or more fertilizers stored in the data storage unit 150, the data processing unit 140 can send a first control instruction for adding the corresponding fertilizer to the aeroponics unit 120 and / or the hydroponics unit 130, so that the nutrient solution preparation module configured by the aeroponics unit 120 and the hydroponics unit 130 adds the corresponding fertilizer in the nutrient solution preparation process to fertilize the plant.

In response to the receipt of the first control instruction, the nutrient solution preparation module configured by the aeroponics unit 120 and the hydroponics unit 130 can increase the addition amount of nitrogen fertilizer in the nutrient solution preparation process.
