Abstract
Tweezers are used in laboratory rice hybridization, including rotating barriers, T -slot tweezers foot, tweezers main part, fastening screw, spring leaf and removable tweezers foot, the tweezers main part pass through fastening screw and spring leaf and link to each other, the spring leaf passes through fastening screw and links to each other with T -slot tweezers foot, T -slot tweezers foot is connected with removable tweezers foot, the rotating barriers on the foot is picked up something with tweezers to the T -slot locks removable tweezers foot through the connection. The utility model discloses a further improvement is gone up on the basis of the ordinary tweezers of tradition to the design, can guarantee to press from both sides to get the in -process seed and do not pressed from both sides getting power and destroy, the convenient work of carrying out rice seed hybridization experiment, and the operator of supplementary rice hybridization experiment makes to test and to accomplish smoothly. The utility model discloses the device simple structure of product, convenient operation pressing from both sides the in -process of getting the seed, do not destroy the kernel texture, simultaneously can also be according to different needs, and the tweezers foot of the required shape of quick replacement.
Description
Technical field
The utility model relates to the fields such as paddy rice cross breeding technology, specifically refers to a kind of laboratory paddy rice cross breeding tweezers.
Background technology
Hybrid rice (hybridrice) refers to select two in heredity, have different, the rice varieties that their merit again can be complementary simultaneously, hybridizes, produces and have heterotic first generation crossbreed, for the production of, Here it is hybrid rice.Hybrid vigour is biosphere universal phenomenon, utilizes hybrid vigour raising crop yield and quality to be one of Main Achievements of modern agriculture science.
Hybrid vigour is the universal phenomenon of biosphere, utilizes hybrid vigour to be one of Main Achievements of modern agriculture science to improve the yield and quality of crops.Select two in heredity, have different, the rice varieties that simultaneously their merit again can be complementary, hybridizes, produces and have heterotic first generation crossbreed, for the production of, Here it is hybrid rice.
Paddy rice has obvious hybrid vigour phenomenon, and be mainly manifested in growth vigorous, well developed root system, big panicle many grains per panicle, the aspects such as strong stress resistance, therefore, utilize the hybrid vigour of paddy rice to be the hope that breeding man is dreamed of to increase substantially rice yield always.But, Genus Oryza self-pollinated plant, female, stamen raw in same grain husk is spent, because grain husk flower is very little, and every flower only ties a seed, therefore be difficult to produce a large amount of first generation by the method for artificial emasculation hybridization to mix mutation, so the hybrid vigour of paddy rice fails to be applied for a long time.Its basic thought and technology, and successfully realize first being completed in Indonesia in 1963 by American HenryBeachell, HenryBeachell is also the father of hybrid rice by some person of academia, and obtains the world food prize of 1996 thus.Because the imagination of HenryBeachell and scheme also exist some defect, cannot promote on a large scale.
Japanese proposed three line breeding method to cultivate hybrid rice afterwards, proposition can find suitable wild male sterile plant as the basis of cultivating hybrid rice, although have found wild male sterile plant through making great efforts Japanese for many years, effect is not fine; Japanese also proposed a series of rice breeding new method in addition, such as catches up with powder etc., but finally cannot complete the industrialization of hybrid rice for various reasons.
Utility model content
The utility model proposes a kind of laboratory paddy rice cross breeding tweezers, auxiliary effect can be played in the test of paddy rice cross breeding, bring great convenience can to the worker participating in experiment.
The technical solution adopted in the utility model is: laboratory paddy rice cross breeding tweezers, comprise butterfly, T-slot tweezer pin, tweezers main body, trip bolt, spring leaf and removable tweezer pin, described tweezers main body is connected with spring leaf by trip bolt, spring leaf is connected with T-slot tweezer pin by trip bolt, described T-slot tweezer pin is connected with removable tweezer pin, is locked replaceable tweezer pin by the butterfly be connected on T-slot tweezer pin.
The beneficial effects of the utility model: design of the present utility model, improve further on the basis of the common tweezers of tradition, can ensure that in gripping process, seed is not destroyed by gripping power, carry out the work of rice paddy seed hybrid experiment easily, the operator of auxiliary water rice hybridization experiment, enables experiment complete smoothly.The apparatus structure of the utility model product is simple, handled easily, in the process of gripping seed, does not destroy kernel texture, simultaneously can also according to different needs, the tweezer pin of the shape required for quick-replaceable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model product.
Embodiment
1 pair of present embodiment is described further with reference to the accompanying drawings.Laboratory paddy rice cross breeding tweezers, comprise butterfly 1, T-slot tweezer pin 2, tweezers main body 3, trip bolt 4, spring leaf 5 and removable tweezer pin 6, described tweezers main body 3 is connected with spring leaf 5 by trip bolt 4, spring leaf 5 is connected with T-slot tweezer pin 2 by trip bolt 4, described T-slot tweezer pin 2 is connected with removable tweezer pin 6, is locked replaceable tweezer pin 6 by the butterfly 1 be connected on T-slot tweezer pin 2.
In the process of tweezers gripping seed, do not worry that firmly the excessive seed that causes damages, because are the effects playing balance clamp power taking in the effect of the structure upper spring sheet 5 of whole tweezers.When pointing applying power, spring leaf can drive tweezer pin to move, pressure is applied to seed, when pressure is excessive, spring leaf 5 will be bent outwardly the unnecessary gripping power of a balance part, now tweezers can by seed gripping firmly, moves on experimental ware and don't can destroy the institutional framework of seed, making seed also can be in active state.
Operation principle:
Experimentally self needs of operator, change for replaceable tweezer pin 6, in Renewal process, butterfly 1 is rotated the position to replaceable tweezer pin 6 skids off from T-slot tweezer pin 2, replaceable tweezer pin 6 is taken off, rotate butterfly 1 after exchanging other tweezer pin for it is locked, can use.
Foregoing describes embodiment of the present utility model with reference to figure 1, it will be understood by a person skilled in the art that, product of the present utility model is not only only limited to above-described embodiment, can make various amendment when not departing from spirit of the present utility model, described amendment also should be included within scope of the present utility model.Scope of the present utility model should be limited by claims and equivalent thereof.
Claims (1)
1. laboratory paddy rice cross breeding tweezers, comprise butterfly (1), T-slot tweezer pin (2), tweezers main body (3), trip bolt (4), spring leaf (5) and removable tweezer pin (6), it is characterized in that: described tweezers main body (3) is connected with spring leaf (5) by trip bolt (4), spring leaf (5) is connected with T-slot tweezer pin (2) by trip bolt (4), described T-slot tweezer pin (2) is connected with removable tweezer pin (6), by the butterfly (1) be connected on T-slot tweezer pin (2), replaceable tweezer pin (6) is locked.
