2. Information processing flow
Next, a process flow of the information processing device 10 according to the embodiment will be described with reference to fig. 4.
The time when the plant is planted is input from the first input unit 12a (S1).
Next, a desired plant growth target is input through the second input unit 12b (S2). The input target of growth is, for example, any of the quality (sugar content, etc.), number, size, and harvest time of the plant to be requested.
Next, time information about a predetermined time is input through the third input unit 12c (S3). Next, the second calculation unit 14b calculates an integration target period from the time inputted from the second input unit 12b to the predetermined time inputted from the third input unit 12c (S4).
Next, the fourth input unit 12d estimates the growth stage of the plant at the predetermined time based on the information on the integration target period (S5).
Specifically, for example, there are 4 estimation methods described below.
As a first method, the second calculation unit 14b estimates the growth stage of the plant from the length of the time during which the target period is integrated. It is more preferable to estimate the growth stage of the plant in consideration of the calendar.
As a second method, the second calculation unit 14b calculates the integrated temperature during the integration target period, and estimates the growth stage of the plant. The calculation of the cumulative temperature is performed based on the temperature information during this period. The temperature information may be acquired from the database when the temperature information is stored in the database stored in the storage unit, but the present invention is not limited to this, and the temperature information may be acquired from an external terminal such as a server connected via a communication network when the information is stored in the external terminal.
As a third method, the second calculation unit 14b calculates an integrated value of the solar radiation amount during the integration target period, and estimates the growth stage of the plant. The cumulative solar radiation amount is calculated based on the solar radiation amount information during that period. In the case where the solar radiation amount information is stored in the database stored in the storage unit, the solar radiation amount information may be acquired from the database, but the present invention is not limited thereto, and in the case where the information is stored in an external terminal such as a server connected via a communication network, the solar radiation amount information may be acquired from the external terminal.
As a fourth method, the second calculation unit 14b calculates an integrated value of the nutrient solution consumption amount in the integration target period, and estimates the growth stage of the plant. The acquisition of the information on the nutrient solution consumption amount may be performed by acquiring the information on the nutrient solution consumption amount from a database stored in the storage unit when the information on the nutrient solution consumption amount is stored in the database, but is not limited to this, and the acquisition of the information on the nutrient solution consumption amount may be performed by acquiring the information on the nutrient solution consumption amount from an external terminal such as a server connected via a communication network when the information on the nutrient solution consumption amount is stored in the external terminal.
In addition to the prediction of the growth stage of a plant by any of the first to fourth methods, the growth stage of a plant may be estimated by combining at least 2 of the first to fourth methods.
Next, the third calculation unit 14c calculates the amount and concentration of the nutrient solution and the supply timing of the nutrient solution based on the estimated growth stage of the plant and the inputted growth target (S6). The amount and concentration of the nutrient solution and the supply timing of the nutrient solution are calculated in consideration of the growth target based on the growth stage of the plant. For example, correspondence data between the growth target and the growth period and the amount, concentration, and the like of the nutrient solution is stored in the storage unit 18, and the amount and concentration of the nutrient solution corresponding to the growth period can be calculated based on the correspondence data. More specifically, the amount and concentration of the nutrient solution and the supply timing of the nutrient solution are determined based on the growth stage of the plant at a predetermined timing and the growth target such as the quality, size, and harvest timing of the plant.
If the input predetermined period is time information of the current time, the growth stage of the plant at the current time can be estimated. In this way, the amount and concentration of the nutrient solution to be supplied at the present time can be calculated.
If the inputted predetermined time is time information of a future time, the growth stage of the plant at the future time can be estimated. When at least one of the data of the predicted temperature, the predicted solar radiation amount, and the predicted nutrient solution consumption amount is used in the estimation of the growth stage of the future period, the data may be stored in the storage unit or in an external terminal connected via a communication terminal.
The amount, concentration, and supply timing of the nutrient solution may be determined as necessary in consideration of the conditions of the farm, the cultivation area, and the like. The input of the growth target may also be performed between step 5 and step S6.

4. Effect of action
According to the present embodiment, for example, the following operational effects can be obtained.
The grower can estimate the plant condition without confirming the plant condition and perform nutrient solution management according to the plant condition. Since the concentration, amount, and supply timing of the nutrient solution can be determined according to the growth target, it is possible to assist and manage the nutrient solution in accordance with the growth target.
Future plans for nutrient management can also be easily specified. Can realize the homogenization and equalization of the cultivation of plants and equalize and stabilize the culture medium environment in the farm. The quality of the cultivated plants can be homogenized, the harvest time can be controlled, and the shipment time can be controlled.
When a grower manages a nutrient solution according to the state of a plant, how to grasp the state of the entire plant depends on the knowledge and skill of the grower, and when a large number of plants are grown, it is difficult to determine the state of the plant by selecting which plant is to be selected from a group of plants in which some irregularities are growing. However, according to the present embodiment, the state of the plant can be easily estimated.
By combining nutrient solution management and temperature management, it is also possible to control the growth of plants.
5. Modification example
Fig. 5 shows the process of nutrient solution management based on the information processing of the above-described embodiment, and this process may be performed in one cycle, but may be performed in a plurality of cycles. After the input of the planting period (I1), a predetermined integrated value of the integration target period is calculated (C1) based on the input information (I2) of the predetermined period or the measured information, and the growth stage is estimated from the predetermined integrated value (C2). The nutrient solution concentration, the amount of the nutrient solution, and the nutrient solution supply timing are calculated based on the estimated growth stage and the inputted growth target (I3) (C3). After the nutrient solution is supplied, each input information and the measurement information are input, and a predetermined integrated value in the integration target period is calculated (C2). A cycle of the steps of inputting information obtained at the predetermined time or by measurement (I2), calculating an integrated value (C1), estimating a growth stage (C2), calculating information on the nutrient solution (C3), and supplying the nutrient solution may be performed a plurality of times.
Examples of applicable plants include vegetables such as tomatoes and fruits such as strawberries.
6. Examples of the experiments
Tomatoes were planted in a culture medium composed of coral sand grains, and were cultivated using the nutrient solution shown in table 1 (nutrient solution in example). Water was added to the nutrient solution in Table 1, and the nutrient solution with the adjusted concentration was supplied to the culture medium. The cultivation is carried out by LED artificial illumination.
[ Table 1]
In the cultivation of tomatoes in this experimental example, tomatoes having an average sugar content of 7.5 (Brix% sugar content) or more could be harvested in m fruit rooms, and both the harvest yield and the price were confirmed to be increased. Table 2 shows the average values of sugar content, yield and yield in each fruit room.
[ Table 2]
[ cultivation comparative test ]
Comparative cultivation tests were carried out using the nutrient solutions of examples and comparative examples. Table 3 shows the compositions of the nutrient solutions of the comparative examples.
[ Table 3]
The cultivation comparison test is carried out until the harvest of the third calyx is finished. Regarding EC concentration changes, the cultivation areas using the nutrient solutions of the examples and the cultivation areas using the nutrient solutions of the comparative examples were changed as shown in table 4.
[ Table 4]
| EC concentration (mS/cm) | |
| Planting stage | 1.0 |
| First calyx flowering | 1.2 |
| Second calyx flowering | 1.4 |
| The third calyx blossoming to the end of cultivation | 1.6 |
The number of test plants was 10 in each of the cultivation areas using the nutrient solutions of the examples and the cultivation areas using the nutrient solutions of the comparative examples. For the test crops, the cultivation areas using the nutrient solutions of the examples and the cultivation areas using the nutrient solutions of the comparative examples were small tomatoes.
The following results were confirmed by a cultivation comparative test. In the cultivation area using the nutrient solution of the example, it is considered that no physiological disorder occurs until the end of the test cultivation, and stable cultivation harvest is achieved.
On the other hand, in the cultivation area using the nutrient solution of comparative example, generation of iron deficiency and manganese deficiency was confirmed in all of 10 plants. Among them, 3 plants underwent whitening due to the development of iron deficiency, and their growth was stopped. The yield of the cultivation area using the nutrient solution of the comparative example was reduced to 1/3, which is the yield of the cultivation area using the nutrient solution of the example.
