Description

Special tool for rapid emasculation of rape Technical Field The utility model relates to the technical field of rape nursing appliances, in particular to a rape flower bud rapid emasculation tool. Background Rape is an important oil crop in China, wherein the main cultivated varieties in China are cabbage type rape and cabbage type rape. For rape breeding, hybridization in the flowering phase is one of the most important main working contents of hybridization breeding. In the traditional working mode, buds which are not yet bloomed need to be opened manually by using forceps, and stamens are removed at the same time for subsequent work. In addition, most of cabbage type rape varieties are self-incompatible varieties, and after flowers of the cabbage type rape are opened, a layer of callose is formed on pistil stigma to prevent fertilization activities of pollen of the cabbage type rape. However, in breeding work, maintaining the self-homozygosity of a variety is an important breeding means. Therefore, for cabbage type rape breeding, it is one of the most commonly used breeding methods to open the buds on the surface of pistil stigma, where callose has not been formed, by physical means and then to pollinate them by artificial pollination. However, due to the particularity of the reproductive activity of rape, the completely removed flower bud cuticle often leads to pistil wither. Therefore, in order to perform subsequent pollination, forceps are generally used to divide the epidermis of the flower bud into an upper half and a lower half during the process of opening the flower bud, then the flower bud at the upper half is removed to expose the stigma of the pistil, and then the stamen is removed by using the forceps. The existing method has the problems of more labor, high cost, time and labor waste, low efficiency and easiness in damaging pistil column heads when the buds and stamens are manually picked. Moreover, in many scientific researches, rape hybridization work is involved, and because of the influence of the factors, and the shorter flowering period of the rape, the hybridization combination is generally less, so that the breeding progress is seriously influenced. Accordingly, the present utility model provides a new solution to the above-mentioned problems. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a special tool for rapid emasculation of rape, which is convenient to operate, high in efficiency, time-saving and labor-saving, and improves the efficiency of rape cross breeding. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The special tool for rapidly emasculating the rape comprises two tool rests, a tool rest and a blade, wherein the blade is detachably arranged on the tool rest, the tool rest is detachably arranged on the tool rest, and the two tool rests are movably connected; The upper end of the tool apron is provided with a plurality of arc-shaped notches, the lower end of the tool apron is provided with a tool slot, and the tool slot is communicated with the arc-shaped notches; the blade is provided with an arc-shaped blade edge, the blade can be embedded and installed in the blade groove, and the arc-shaped blade edge is matched with the arc-shaped notch. The utility model is further characterized in that the tool rest is integrally connected with the connecting seat, the first upper end surface of the connecting seat is provided with the transversely arranged limiting groove, the second lower end surface of the tool rest is integrally connected with the limiting part, and the limiting part can be embedded into the limiting groove to abut against and limit. The utility model is further arranged that the knife slot is arranged on the first lower end surface of the limiting part, the upper end of the knife blade is abutted against the second upper end surface of the knife slot, and the lower end of the knife blade is abutted against the lower bottom surface of the limiting groove to limit. The utility model is further characterized in that a plurality of gaps which longitudinally penetrate through are formed in the side face of the limiting part, and the gaps are arranged at intervals transversely. The utility model is further characterized in that the arc-shaped notches on the tool apron are equidistantly arranged side by side, and the sizes of the arc-shaped notches are sequentially reduced from inside to outside. The utility model is further arranged that the edge of the arc-shaped edge of the blade protrudes out of the arc-shaped notch on the tool apron. The utility model is further characterized in that the tool rest is provided with a through connecting hole, and the two tool rests are arranged in a crossed manner and movably connected through bolts passing through the connecting hole.
