[0044] The two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] First embodiment:

[0046] Figures 1-2 A broccoli plus generation breeding method based on light environment regulation is shown, which includes a planting greenhouse for plus generation breeding, and further includes the following steps:

[0047] S0, installing a plurality of matrix arranged light supplement lamps 3 on the inner top wall of the planting greenhouse and a mobile monitoring unit, the mobile monitoring unit including a plurality of lead screws 4 connected through a conveying belt 5 and an image collector threaded on the surface of the lead screw 4 for monitoring the growth state of the broccoli in the planting greenhouse;

[0048] S1, establishing a plane coordinate in the planting greenhouse, and setting the coordinates of the plurality of light supplement lamps 3 in the vertical plane one by one;

[0049] S2, during the broccoli plus generation breeding process, the image collector reciprocally moves to monitor the growth state of the broccoli on the same axis, and judges whether the monitored broccoli below is in the budding stage;

[0050] S3, when judging whether the broccoli is in the budding stage, an auxiliary unit is used to assist in judging the growth state of the broccoli in the shielding state;

[0051] S4, if the broccoli is before the budding stage, the light illumination time of the light supplement lamp 3 is 20 hours / day, and if the broccoli is after the budding stage, the light illumination time of the light supplement lamp 3 is 22 hours / day.

[0052] Specifically, the spectrum of the light supplement lamp 3 is composed of 20% white light of 6500k, 50% red light of 660nm, and 30% far-red light of 730nm, and the light intensity is 400μmol·m -2 ·s -1 , and the light intensity is intelligently adjusted according to the size of the plant;

[0053] During the growth of the broccoli plants, the image collector reciprocally moving on the surface of the lead screw 4 is used to take pictures to monitor the growth state of the broccoli plants, so as to determine the size of the plants and whether the plants have present buds, and then serve as the basis for subsequent adjustment of the working time of the light supplement lamp 3, and also send the coordinate information of the region where the present buds are present in a scattered manner to the position of the light supplement lamp 3 at the corresponding position, adjust the time of the light supplement lamp 3 in the corresponding region, and realize intelligent adjustment;

[0054] During the moving and shooting monitoring of the image collector, if the inside leaves of the plants are straight up and cause shielding, it will affect the determination of the present buds, at this time, the auxiliary unit is needed to pull apart the plants in the shielding state to expose the inside for the image collector to take pictures, and at the same time, the auxiliary unit can also be used to comb the shielding leaves to prevent shielding, which can facilitate the viewing of the growth state of the subsequent flower balls in the plants, and also ensure that the flower balls of the plants are regulated and promoted to bloom in advance by light signals.

[0055] Figures 3-5 The auxiliary unit is shown to include a moving trolley 1 moving in the planting greenhouse, and the moving trolley 1 is signal connected with the image collector, a multi-axis mechanical arm 2 is installed on the top of the moving trolley 1, a movable comb unit 6 is connected at the tail end of the multi-axis mechanical arm 2, the movable comb unit 6 includes a comb rack 61, a rectangular groove is arranged in the inside of the comb rack 61, a movable plate 63 is connected in the inside of the rectangular groove through a shaft, the thickness value of the movable plate 63 is less than the thickness value of the comb rack 61, a driving motor 62 is installed on the top of the comb rack 61, and the output end of the driving motor 62 is connected with the shaft.

[0056] A comb plate 64 is installed on one side surface of the movable plate 63 through a connecting block, and the comb plate 64 is in the same height with the comb rack 61, and the surfaces of the comb rack 61 and the comb plate 64 close to each other are both provided with protruding racks.

[0057] The cross-sectional length value of the comb plate 64 is less than the cross-sectional length value of the comb rack 61, and the racks on the surfaces of the comb plate 64 and the comb rack 61 are one-to-one corresponding.

[0058] Specifically, after the auxiliary unit receives the coordinate information of the broccoli with shading from the image acquisition unit, the moving trolley 1 moves to the corresponding coordinates. Then, the multi-axis robotic arm 2 moves the comb frame 61 to the position where the broccoli leaves are shading. Using its flat design, the comb frame 61 is inserted into the gaps in the shading. Subsequently, the drive motor 62 is activated, causing the movable plate 63 to open, which in turn causes the upright leaves to open, exposing the interior (e.g., ...). Figures 6-7 As shown), to facilitate image acquisition, the open movable comb unit 6 is then moved to both sides of the single covering leaf branch, allowing the comb frame 61 and movable plate 63 to clamp the single covering leaf. Then, the drive motor 62 resets, causing the movable plate 63 to reset as well. At this point, the racks move closer together, and the multi-axis robotic arm 2 moves upward, causing the closed movable comb unit 6 to move upward, performing a combing operation on the covering leaf to destroy the covered leaf. This prevents further shading and ensures that the cauliflower head at this coordinate position receives normal light (e.g., ...). Figure 8 (As shown).

[0059] Because leaves grow densely, cutting operations may damage other unrelated branches and leaves, affecting the plant's subsequent normal growth, or require high precision in machine cutting operations, leading to increased costs. Compared to cutting and covering leaves, using comb-tooth operations can achieve the effect of covering leaves with a hammer while requiring less precision, avoiding accidental damage, ensuring safety, and controlling costs.

[0060] The fill light 3 is connected to the image acquisition unit signal, and step S4 also includes the following steps:

[0061] S41. The image acquisition device saves the image data of broccoli at the same coordinate position and marks broccoli that show abnormal growth.

[0062] S42. Arrange the image data of broccoli at the same coordinate position saved in S41 in chronological order, compare them, and determine whether the growth rate of broccoli at different coordinate positions is the same.

[0063] S43. If they are the same, the light intensity of supplemental light 3 remains unchanged. If they are different, increase the light intensity of supplemental light 3 at the position corresponding to the broccoli with the slower growth rate.

[0064] Specifically, the supplemental light 3 can intelligently adjust the light intensity according to the growth status of the plants to ensure the synchronization of the growth status of the plants in that area and reduce the possibility of localized scattered bud formation.

[0065] S2 also includes the following steps:

[0066] S21, image shooting of the inner flower ball of the broccoli below during the movement of the image collector, judging whether the bud appears, if the bud appears, the coordinates of the broccoli at the corresponding position are transmitted to the light supplement lamp 3 in the corresponding light supplement range, so that the light supplement time is changed from 20 hours / day before the bud appears to 22 hours / day;

[0067] S22, in S21, the image collector shoots the broccoli below and the leaf shielding phenomenon occurs, the coordinates of the broccoli at the corresponding position are transmitted to the moving trolley 1.

[0068] S3 further comprises the following steps:

[0069] S31, the moving trolley 1 moves to the broccoli where the leaf shielding phenomenon occurs according to the coordinates sent by S21, and then the multi-axis mechanical arm 2 is used to insert the flat active comb tooth unit 6 into the gap of the shielding leaf;

[0070] S32, then the driving motor 62 is started to drive the active plate 63 to open, expand the shielding leaf, expose the inside, facilitate the image collector to collect images and judge the flower ball condition in the shielding leaf;

[0071] S33, after the image collector obtains the image, the multi-axis mechanical arm 2 is used to place the shielding leaf in the middle of the open active plate 63 and the comb tooth rack 61, then the driving motor 62 is reversely rotated to reset, after the active plate 63 and the comb tooth rack 61 restore the flat state, the multi-axis mechanical arm 2 moves upward to comb the shielding leaf, so that the shielding effect on the flower ball is lost, and the subsequent photosynthesis is ensured to be carried out normally.

[0072] Second embodiment:

[0073] The side surface of the comb tooth plate 64 away from the rack is provided with a pressure sensor and a displacement sensor in signal connection with the multi-axis mechanical arm 2, and the S32 further comprises the following working steps:

[0074] S321, before the multi-axis mechanical arm 2 is started, the image collector shoots and identifies the horizontal dimension of the shielding area of the broccoli in the shielding state, and records the diameter of the shielding area as R;

[0075] S322, after the driving motor 62 is started, the comb tooth plate 64 expands outward, in this process, when the pressure sensor senses the pressure effect, the displacement sensor records the horizontal displacement distance of the comb tooth plate 64 at this moment, and records it as L;

[0076] S323, judging the size of R and L, if R is greater than L, it indicates that the flower ball in the shielding leaf is encountered in the displacement process of the comb tooth plate 64, the driving motor 62 stops driving the comb tooth plate 64 to expand outward, and directly enters S33;

[0077] S324, if R is not less than L, the image collector continues to shoot to view whether there is a flower ball in the shielding leaf, if there is, continue to S33, otherwise mark the broccoli at the coordinate position as abnormal.

[0078] Different from the first embodiment, the present embodiment is improved for the situation of encountering flower ball in the expansion shielding process, thereby avoiding the extrusion damage to the surface of the flower ball when the comb plate 64 is forced to expand outward.

[0079] Specifically, after the flat active comb unit 6 is inserted into the shielding leaf, if the expansion distance is less than the size of the shielding area, it indicates that there is a flower ball in the shielding leaf, at this time, it is not suitable to continue to expand outward, and the comb cleaning operation of the shielding leaf can be directly performed.

[0080] If there is no flower ball in the shielding leaf, after being inserted into the shielding gap, the comb plate 64 may not encounter the obstruction of the flower ball during the expansion process, at this time, the image collector needs to perform supplementary identification, after the supplementary judgment, the broccoli with the flower ball is subjected to the comb cleaning operation of the shielding leaf, otherwise, it is marked as abnormal.

[0081] In summary, in the process of broccoli breeding, the present application uses the light supplementing lamp 3 to provide intelligent light supplementing operation for the broccoli, and uses the image collector to monitor the growth state of the broccoli, after the image collector detects that the broccoli appears shielding leaf state leading to recognition interference, the coordinate information of the corresponding broccoli is transmitted to the mobile trolley 1, the mobile trolley 1 and the multi-axis mechanical arm 2 work cooperatively, the comb rack 61 is inserted into the branch gap, the movable plate 63 is opened by driving the motor 62, the branches are expanded, the image collection is facilitated, then the multi-axis mechanical arm 2 moves the active comb unit 6 in the closed state to perform the comb operation, the shielding leaf is destroyed, the photosynthesis is ensured to be normal, and during the expansion process of the movable plate 63, the identification judgment is performed, the extrusion damage to the flower ball is avoided, and the safety of the flower ball is ensured.

[0082] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to this, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
