5 results about "Cotton bud" patented technology

The application belongs to the technical field of agricultural machinery, and particularly relates to a cotton topping device and method based on microwave technology. 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 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.
