The application provides a cotton top bud three-dimensional coordinate extraction method and system based on key point detection. The method comprises the following steps: collecting a cotton plant image sample, and pre-processing the cotton plant image; labeling the position of the cotton bud on the pre-processed image sample, and dividing the labeled image sample into a training set and a verification set; training a deep learning network by using the training set; processing the labeled image sample in the verification set by using the trained deep learning network, and obtaining the position of the two-dimensional key point of the cotton top bud; and extracting the three-dimensional coordinate of the cotton top bud by using a ROS-based three-dimensional coordinate extraction method according to the position of the two-dimensional key point of the cotton top bud. The scheme provided by the application significantly improves the problems of low recognition accuracy of top end recognition and incoherence of the target detection model which can only output two-dimensional coordinates and is not conducive to mechanical operation. Therefore, the accuracy and efficiency of cotton top bud recognition are effectively improved, and accurate positioning is provided for subsequent mechanical topping.

The invention discloses an unmanned aerial vehicle cotton topping method and system based on machine vision. According to the method, an unmanned aerial vehicle is controlled to fly in an interlaced operation mode, an airborne vision module is used for collecting cotton terminal bud images of adjacent non-operation rows, and image stability is judged; after terminal buds are recognized, the spatial positions of the terminal buds are determined, time delay is calculated, and a spraying instruction is generated; and controlling the pesticide application module to accurately apply pesticide to the terminal buds according to the instruction. According to the interlaced operation mode, the downwash wind field of the unmanned aerial vehicle acts on the current flying row, and disturbance to cotton plants in adjacent non-operation rows is reduced to the maximum extent. The system comprises an unmanned aerial vehicle platform, a visual module, a pesticide application module and a flight control and processing module. Spraying time is synchronized through a delay compensation method, and a binocular vision positioning technology is combined, so that positioning errors caused by interference and movement of a downwash wind field of the unmanned aerial vehicle are effectively overcome, the recognition accuracy and the pesticide application precision are remarkably improved, and efficient cotton topping is realized.

The application comprises an identification controller, a microwave emission mechanism, a swing mechanism and a cover, can convert electric energy into high-frequency electromagnetic waves, and makes the water and other polar molecules of cotton buds continuously rotate and rub to generate heat under the action of the electric field and the magnetic field, and finally makes the buds burn and deteriorate. Compared with the prior art, the application does not use chemical agents, has no environmental pollution problem, and has lower labor cost.

The application discloses a cotton topping regulator with the functions of topping control and fruit promotion, and belongs to the technical field of crop plant growth regulators.The application adopts special compound active components and special inactive additive systems, does not add any exogenous hormones, insecticides, fungicides and other auxiliary materials, and constructs a differential target regulation mechanism.The regulator can act on the cotton apical meristem, flower bud differentiation tissue and phloem nutrient transport channel, and simultaneously realizes four functions of apical vigorous shoot inhibition, invalid bud removal, bud and boll shedding inhibition and photosynthetic product directional transport, thereby replacing artificial topping operation.The application can reduce the cotton bud and boll shedding rate by 18.2%-23.7%, increase the per mu seed cotton yield by 12.6%-19.3%, and simultaneously optimize the cotton fiber quality;the preparation has strong storage stability, is suitable for unmanned aerial vehicles, large-scale traction spraying machines and other full-process mechanized plant protection equipment, has a green and waste-free preparation process, meets the development needs of cotton simplified and green cultivation, and has high field popularization value.

The application relates to application of a GhBAM1 gene in reducing cotton bud boll shedding rate, and a cotton bud boll shedding gene GhBAM1 is identified for the first time, and the gene has important value for theoretical research on molecular mechanisms of cotton bud boll shedding. By knocking out an endogenous gene GhBAM1 of upland cotton, the cotton bud boll shedding rate can be reduced, the high-temperature stress resistance of the cotton can be improved, high-yield and stable-yield cotton breeding materials can be created, and a cotton gene resource library is enriched, and the application has important practical application significance for cotton breeding.

The present invention relates to a cotton bud with an internal channel comprising a hollow stick, the ends of which are externally covered with cotton, leaving holes in the centre that are not covered at the tips. In this way, an internal channel is formed that makes up the entire longitudinal interior of the hollow stick and can have spiral-shaped notch. As such, when a user uses the cotton bud, the external ends of the stick clean the user's ear canal via the cotton, while the internal part facilitates the entry of ear wax through the holes and into the channel, thereby reducing the accumulation of ear wax pushed towards the internal part of the ear canal.

The application relates to a cotton topping machine and a topping method for realizing self-walking and target shooting, and the topping machine comprises a self-walking vehicle body, an image acquisition module, a control module and a target shooting spraying module; the self-walking vehicle body is used for driving to a topping point position according to a preset step distance; the image acquisition module is used for acquiring a cotton top image of the topping point position and transmitting the cotton top image to the control module; the control module is used for determining a target cotton top bud and a target cotton bud top position according to the cotton top image; the target shooting spraying module comprises a plurality of rotary spray rods, the control module controls the rotary spray rods to rotate above the target cotton top bud position, and determines a target nozzle to perform chemical topping on the target cotton top bud. The cotton topping machine is simple in structure, the rotary spray rods can realize automatic target shooting, the target shooting mode is simple and accurate, the topping rate is high, and the waste of pesticide application is reduced.

The invention relates to the technical field of fruit pollination, and discloses a method for improving the fruit bearing rate and reducing the fruit cracking rate of pomelo, which comprises the following steps: step 1, pollen screening and preparation: collecting mature flowers of kumquat and honey pomelo in a full-bloom stage, removing petals and calyx, taking out anther, naturally airing, sieving and removing impurities to obtain single pollen, sealing and refrigerating for later use, detecting pollen vitality before taking, and screening pollen with vitality greater than or equal to 85%; step 2, selecting flower buds: when the pomelo flowers do not bloom, selecting the flower buds which grow robustly and are full and free from diseases and insect pests as pollination objects, and removing weak, small and deformed flower buds; the stamens and petals of the selected flower buds are removed, only pistils and calyxes are reserved, and pistil stigmas are prevented from being damaged in the operation process; 4, pollination operation: carrying out pollination operation in the morning of a sunny day, and dipping the pollen prepared in the step 1 with a sterile cotton swab. The pollen consumption is less than 1 / 5 of the daily required pollen, so that the cost is greatly reduced.
