Cotton closing selfing machine and method for same

Abstract

The invention discloses a closing selfing machine and a closing method for the scientific researching and the improved variety breeding of cotton, and relates to the technical field of agricultural machinery. A positioning plate (1) is arranged at a port of an upper clamp (12), wherein an entrainment piece (3) is arranged at a bud cabin (5) of the upper clamp (12), and is fixed by a screw (4); a blade notch (2) is formed between the positioning plate (1) and the entrainment piece (3); the tail parts of the upper clamp (12) and a machine body (17) are movably connected through a shaft pin (14), and a spring (13) is arranged between the tail parts of the upper clamp (12) and a machine body (17); a blade (9) is arranged on the positioning plate (11) at a port of the machine body (17), and is fixed by a screw(8); bud cabins (5 and 7) with diameters of about 1.8cm are formed after the port of the upper clamp and a port of the machine body are closed; an adhesive tape box (15) is arranged on the tail part of the machine body (17), and a tape guide groove (18) is formed in the lower part of the machine body (17); the front end of the tape guide groove is closed with the port of the machine body, and an adhesive tape outlet (10) is formed. According to the closing selfing machine and the closing method, petals are prevented from being opened by annular adhesion of an adhesive tape, and similarly, adhesive tape rings are adhered to stalks as harvesting marks.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a flower-sealing selfing device and a flower-sealing method for cotton scientific research and improved seed breeding. Background technique [0002] In the process of breeding genetic materials, variety breeding, and breeding of improved varieties, in order to maintain the seed nature of genetic materials or parental materials, or accelerate the homozygous stability of hybrid offspring, it is necessary to seal the flowers of cotton to prevent the petals from opening, thereby avoiding different plants Fertilization (hybridization) of the pollen, so that the flowers are strictly selfed. Only strictly self-sealing of flowers can be beneficial to the preservation of genetic material, the improvement of the purity of parents, and the homozygosity of segregation generations. At present, self-fertilization of sealing flowers is usually done by researchers and technicians...

Problems solved by technology

However, the consumables used in these methods are too specific, and it is difficult to find substitutes in the market when the consumables are in short supply.

The consumables used will put pressure on the farmland ecology if they are not recycled

And all these methods, all do not make reliable mark on flower (bell) stalk, when leading to harvesting cotton at maturity stage, can't distinguish self-bred boll and natural boll
