When the first liquid L1 is transported to the plant cultivation tank 110 and absorbed by the plant 200 cultivated in the plant cultivation tank 110, the capacity of the first liquid L1 in the nutrient tank 120 will be reduced, and the control device 170 will be based on the capacity measurer. The data provided by 133 controls the water supply tank 180 to supply water to the nutrient tank 120.

On the other hand, when the conductivity of the first liquid L1 is higher than the value preset by the control device 170, the conductivity detector 132 will provide the data of the conductivity, and the control device 170 can also control the water supply tank 180 to supply the nutrient solution according to the setting.

In practical applications, the time control unit 150 is configured to set the time points in the two adjacent time units X to be the same. As shown in Fig. 2, the first liquid L1 in the nutrient bath 120 becomes peracid as an example. The pH detector 131 detects the pH of the first liquid L1 in the nutrient tank 120 and provides data, that is, the pH of the first liquid L1 in the nutrient tank 120, and the portion control unit 160 sets the supply according to the data of the pH of the first liquid L1. The tank 140d supplies the alkaline nutrient solution (i.e., the second liquid L2) to the nutrient tank 120 at each time point, and the control device 170 controls the supply tank 140d to supply the nutrient tank 120 with the alkaline amount of M according to the setting. Nutrient. It is assumed that the time for completely transferring the capacity of the first liquid L1 in the nutrient tank 120 to the plant cultivation tank 110 is one time unit X, and the control device 170 divides the second liquid L2 twice or more according to the setting of the time control unit 150. The time unit X is supplied to the nutrient tank 120 on average. For example, in the present embodiment, when the first liquid L1 in the nutrient tank 120 is transported to the plant cultivation tank 110, the control device 170 controls the supply tank 140d to divide the alkaline nutrient solution according to the setting of the time control unit 150. Three times in the time unit X are supplied to the nutrient tank 120 on average, that is, at the beginning of the time unit X, at the time of X/3 and 2X/3, the supply tank 140d will respectively give an alkaline amount of M/3. The nutrient solution is supplied to the nutrient tank 120. in case After the end of the time unit X, the pH detector 131 detects the pH of the first liquid L1 and provides data indicating that the pH of the first liquid L1 of the nutrient tank 120 has not risen to a preset value, and the control device 170 will be the second one. The time unit X repeats the above procedure until the pH of the first liquid L1 of the nutrient bath 120 rises to a preset value after the end of a certain time unit X. When the pH of the first liquid L1 of the nutrient tank 120 rises to a preset value, the supply tank 140d no longer supplies the alkaline nutrient solution to the nutrient tank 120, and the control device 170 will again take the nutrient solution in a time unit X. The first liquid L1 in the tank 120 is sent to the plant cultivation tank 110, so that the alkaline nutrient solution can be more uniformly present in the first liquid L1, and the adjustment cost of the nutrient solution and the chance of generating sediment can be reduced to achieve Better nutrient adjustment effect, and improve the production quality of the plant 200 and shorten the growth schedule. In the present embodiment, the operation time of the first pump 121 is 3X. It should be understood that the above operational timings are equally applicable to the case where the first liquid L1 becomes overbased.

In order to further enable the alkaline nutrient solution to be more uniformly present in the first liquid L1, the time control unit 150 can also be used to set the time point system in the two adjacent time units X to be different. As shown in FIG. 3, in the second time unit X, the control device 170 controls the supply tank 140d to supply the alkaline nutrient solution to the nutrient tank 120 with respect to the first time unit according to the setting of the time control unit 150. The time in X is staggered. In the present embodiment, the time of the shift is half of the time difference in the supply of the alkaline nutrient solution to the nutrient tank 120 each time the supply tank 140d in the first time unit X, that is, X/6. That is to say, in the second time unit X, the supply tank 140d supplies the alkaline nutrient solution of the M/3 amount to the time of X/6, 3X/6 hour and 5X/6, respectively. The nutrient tank 120 is further configured to further enable the alkaline nutrient solution to be more uniformly present in the first liquid L1, thereby further reducing the adjustment cost of the nutrient solution and the chance of generating sediment, so as to achieve better nutrient adjustment effect, and Improve the production quality of the plant 200 and shorten the growth schedule. It should be understood that the above-mentioned staggered time is only an illustration and is not intended to limit the present invention. Those having ordinary knowledge in the technical field of the present invention should appropriately select the supply tank to the liquid in any time unit X according to actual needs. The tank 120 supplies the time at which the second liquid L2 is to be staggered.

As shown in FIG. 4, when the conductivity of the first liquid L1 in the nutrient bath 120 is lower than a preset value, the portion control unit 160 sets the supply tank 140a according to the data of the conductivity of the first liquid L1. / or the supply tank 140b supplies the second liquid L2 to the nutrient tank 120 at each time point, and the first liquid L1 in the nutrient tank 120 is transported to the first time unit X of the plant cultivation tank 110, and is controlled. The device 170 first controls the supply tank 140a to divide the concentrated nutrient solution A (ie, the second liquid L2) three times at the beginning of the first time unit X, X/3 time, and 2X/3 time according to the setting of the time control unit 150. It is supplied to the nutrient tank 120 (for example, the amount of the concentrated nutrient solution A is H/3), and then the supply tank 140b is controlled to concentrate the nutrient solution B (ie, the second liquid L2) in the second time unit. At the beginning of X, at X/3 and 2X/3, the average is supplied to the nutrient tank 120 three times (for example, the amount of concentrated nutrient B is K/3 each time). When the conductivity of the first liquid L1 of the nutrient tank 120 rises to a preset value, the supply tank 140a and the supply tank 140b no longer supply the concentrated nutrient solution A and the concentrated nutrient solution B to the nutrient tank 120, and the control device 170 The first liquid in the nutrient tank 120 will be again taken in one time unit X L1 is transported to the plant cultivation tank 110, so that the concentrated nutrient solution A and the concentrated nutrient solution B can be more uniformly present in the first liquid L1, and the adjustment cost of the nutrient solution and the chance of generating sediment can be reduced to achieve better. The nutrient adjustment effect, and improve the production quality of the plant 200 and shorten the growth time course.

In order to further enable the concentrated nutrient solution A and the concentrated nutrient solution B to be more uniformly present in the first liquid L1, as shown in FIG. 5, in the second time unit X, the control device 170 sets the time according to the time control unit 150. The time during which the supply tank 140b supplies the concentrated nutrient solution B to the nutrient tank 120 is shifted from the time in the first time unit X. In the present embodiment, the time of the shift is half of the time difference in which the supply tank 140a supplies the concentrated nutrient solution A to the nutrient tank 120 in the first time unit X, that is, X/6. That is to say, in the second time unit X, the supply tank 140b supplies the concentrated nutrient solution B of K/3 at a time of X/6, 3X/6 hours and 5X/6, respectively. The liquid tank 120 further enables the concentrated nutrient solution A and the concentrated nutrient solution B to be more uniformly present in the first liquid L1, thereby further reducing the adjustment cost of the nutrient solution and the chance of generating sediment, so as to achieve better nutrient solution. Adjust the effect and improve the production quality of the plant 200 and shorten the growth schedule. It should be understood that the above-mentioned staggered time is only an illustration and is not intended to limit the present invention.
