Description

A kind of apparatus of Maize Parthenogenesis Induced by Chemicals shearing filigree

Technical field

The utility model belongs to the equipment technology field of corn single-female generation shearing filigree, and in particular to a kind of chemical agent The apparatus of filigree is sheared in inducing maize single-female generation.

Background technology

It is that it carries out the key core link of corn hybridization breeding to cultivate self-mating system, and Parthenogenesis Induced by Chemicals method can Shorten breeding cycle, it is cost-effective, the advantage of objective trait Breeding Efficiency is improved, currently used single-female generation method has chemistry Medicament single-female generation and biological induced parthenogenesis method, chemical agent single-female generation method have simple and easy advantage, not flower training Seedling survive the winter difficulty the problem of, directly gone beyond the difficulty that significant obstacle-dyeing of biological induced parthenogenesis method doubles, and Reduce the external interference to some Chemical mutagenesis inhereditary materials, the characteristic of original germplasm can be preferably kept, at present, in field During Maize Parthenogenesis Induced by Chemicals, existing method is typically according to strict bagging, with common scissors after alcohol scouring Aging filigree is sheared, and induction medicament is smeared or sprayed to the tender filigree of children, the method and is difficult to reach preferable pesticide supplying effect, And although in strict bagging, the problem of in the case of blocking and being operated during loose powder is avoided still with the presence of pollen contamination, Produce substantial amounts of pseudo- homozygote.

The content of the invention

The purpose of this utility model is to provide a kind of apparatus of Maize Parthenogenesis Induced by Chemicals shearing filigree, made User uses comfortably, improves efficiency, avoids the pollution of pollen, and presss from both sides the state that crop can remain closed at the moment, just In storage.

To achieve the above object, the utility model provides following technical scheme：A kind of lonely female life of chemical agent inducing maize The apparatus of shearing filigree is grown, cuts portion provided with first, second folder being pivotally connected, first, second folder is cut portion and is being pivotally connected The front end at place is provided with first, second relative folder crop, and rear end is then installed with the first grip handle and the second hand-rotating respectively Handle, first, second folder, which is cut, to be relatively set with folder on the inside of portion and cuts groove, and described press from both sides cuts the thickness of groove and be not less than 2cm, institute State and blade is provided with the outside of the second folder crop, the first, second grip handle is made up of expansion link and holding end, described to stretch Contracting rod set, which is connected on, to be held inside end, and the inner side of the expansion link pivot end is relative to be provided with magnet piece, if expansion link upper surface is provided with Work dynamic raised, hold end and be provided with screens groove corresponding with projection, it is described to hold being coated with Anti-slip cover and being provided with for end Anti-dropout ring.

Preferably, the first folder crop and the second grip handle constitute the first folder and cut portion, the first grip handle The second folder is constituted with the second folder crop and cuts portion, and the first folder, which is cut portion and pressed from both sides with second, to be cut portion and be connected by pivoting.

Compared with prior art, the beneficial effects of the utility model are：The utility model is scientific and reasonable for structure, safe to use Convenient, there is provided magnet piece, can make the cutting implement state that used time retaining clip crop does not close, be easy to store, first, second The expansion link that grip handle is set, the decreased food of cutting implement can be extended, there is provided blade, add the work(of cutting implement Can, hold end setting and be coated with Anti-slip cover and be provided with anti-dropout ring, instrument drops when avoiding operation, passes through expansion link Projection with hold handle screens groove clamping, be easy to control grip handle length, when being operated in field, cut with the folder of this apparatus Groove directly clamps maize ear upper end, and female fringe bract not damaged can be achieved, and filigree is neat from the apparatus and bract contact position Fracture, extract and cut filigree, one section of bract empty barrel cavity for being adapted to injection induction medicament can be left on female fringe top, by chamber The tender filigree of children and the abundant contact area of decoction and reaction time can be improved after internal injection induction medicament, while avoids pollen Pollution, operating efficiency can be greatly enhanced in the practical operation of field.
