Abstract

The utility model relates to a shear, in particular to a shear for eliminating tassels in corn breeding. The shear aims to solve the problem that time and labor are wasted in operation of tassel elimination without special tassel elimination tools. A semicircular blocking piece is fixedly connected with the front end of the outer side of a shear piece of a shear body to be a whole, and the front end of the other shear piece of the shear body is of a hooked structure. The shear is suitable for operation of tassel elimination in corn breeding.

Description

In a kind of corn breeding for the scissors of emasculation fringe

Technical field

The utility model relates to a kind of scissors.

Background technology

Detassel is exactly to remove the tassel at top to the regular period at corn growth, this is the necessary links in the maize field production of hybrid seeds, after female fringe removes tassel, accept paternal pollen, thereby production Hybrid F1, and then can absorb and manufacture the throughput direction of nutrient by changing plant, and reach premature ripening 3-5 days, increase per unit area yield 10% left and right.In the hybrid combination test arm is joined district, after the emasculation fringe, can just know whether and finish pollination without other mark in addition, reduce the selfing rate simultaneously.

But at present in process of production, mostly adopt the mode of hand-lifting or common scissors to carry out the emasculation fringe, this mode is too high or have under the wind state at tassel, need the both hands cooperation, a hand steered firmly crop, the operation of another hand emasculation fringe, waste time and energy, and very easily cause milpa to sustain damage.

The utility model content

The utility model is the problem that causes detassel fringe operation to be wasted time and energy due to the instrument that there is no special-purpose emasculation fringe in order to solve, thereby the scissors for the emasculation fringe is provided in a kind of corn breeding.

In a kind of corn breeding, for the scissors of emasculation fringe, it comprises scissors body 1, and it also comprises semicircle catch 2; The outside front end of the shear blade part that is fixed as one in described semicircle catch 2 and scissors body 1; In described scissors body 1, the front end of another shear blade is hook formation.

In scissors body 1, the front end of another shear blade is that the narrowest hook-shaped place is 2cm to 4cm.

The catch that semicircle catch 2 is 3cm for radius.

One end of scissors of the present utility model is with crotch, and for fixing tassel, then closed scissors is cut off tassel.The utility model only needs one hand can complete the operation of emasculation fringe, time saving and energy saving.And the utility model can guarantee that milpa is injury-free, simultaneously because front end of the present utility model is not all pointed, therefore easy to carry, be difficult for causing operating personnel's health or article come to harm or destroy.

The accompanying drawing explanation

Fig. 1 is the structural representation under open configuration of the present utility model; Fig. 2 is the structural representation under closure state of the present utility model;

Embodiment

Embodiment one, in conjunction with Fig. 1 and Fig. 2, this embodiment is described, in a kind of corn breeding, for the scissors of emasculation fringe, it comprises scissors body 1, and it also comprises semicircle catch 2; The outside front end of the shear blade part that is fixed as one in described semicircle catch 2 and scissors body 1; In described scissors body 1, the front end of another shear blade is hook formation.

One end of scissors of the present utility model is with crotch, and for fixing tassel, then closed scissors is cut off tassel.The utility model only needs one hand can complete the operation of emasculation fringe, time saving and energy saving.And the utility model can guarantee that milpa is injury-free, simultaneously because front end of the present utility model is not all pointed, therefore easy to carry, be difficult for causing operating personnel's health or article come to harm or broken mark.

It is too high or have in the situation of wind and use that present embodiment is particularly useful for tassel.

Difference for the scissors of emasculation fringe in the described a kind of corn breeding of embodiment two, this embodiment and embodiment one is, in scissors body 1, the front end of another shear blade is that the narrowest hook-shaped place is 2cm to 4cm.

In present embodiment, the bar footpath that hook formation only need be greater than tassel gets final product, and is proven, and 2cm to 4cm is best value.

Difference for the scissors of emasculation fringe in the described a kind of corn breeding of embodiment three, this embodiment and embodiment one or two is, the catch that semicircle catch 2 is 3cm for radius.

In present embodiment, the catch that semicircle catch 2 is 3cm, can effectively stop that scissors stabs human body or clothes, is unlikely to again that volume is excessive causes carrying inconvenience.

Claims (3)

1. In a corn breeding for the scissors of emasculation fringe, it comprises scissors body (1), it is characterized in that: further comprising semicircle catch (2); The outside front end of the shear blade part that is fixed as one in described semicircle catch (2) and scissors body (1); In described scissors body (1), the front end of another shear blade is hook formation.
2. In a kind of corn breeding according to claim 1 for the scissors of emasculation fringe, the front end that it is characterized in that another shear blade in scissors body (1) is that the narrowest hook-shaped place is 2cm to 4cm.
3. In a kind of corn breeding according to claim 1 and 2 for the scissors of emasculation fringe, it is characterized in that the catch that semicircle catch (2) is 3cm for radius.
