Abstract

A kind of tobacco hybridization production of hybrid seeds labeling method, it relates to tobacco hybridization seeding technique field.Its packet technology scheme is: after tobacco hybridization seed production and pollination terminates, and first pinches the anthocaulus of pollination flower with left hand, then laterally removes two pieces of sepals from root with the right hand, and action wants slim and graceful.The present invention it be not required to bolt line, band or be coated with stamp-pad ink just can be marked, low cost, accuracy rate height.

Description

A kind of tobacco hybridization production of hybrid seeds labeling method

Technical field

The present invention relates to tobacco hybridization seeding technique field, particularly relate to a kind of tobacco hybridization production of hybrid seeds labeling method.

Background technology

The tobacco hybridization production of hybrid seeds, in order to improve seed production purity, prevents from mixing and adopts or artificially mix, do after the most all using pollination The method of labelling, so during the whole production of hybrid seeds, can effectively control the production of hybrid seeds caused because of artificial or other factors Purity is inadequate, thus brings loss to seeding farmer and manufacturer, and the method therefore using hybrid seeding labelling is international at present The general tobacco hybridization production of hybrid seeds labeling method just used of leading company is bolt line or band, or uses painting stamp-pad ink, and labelling is obvious, But this kind of method there is also certain defect, following point:

1, cost of labor is high, uses bolt line or band, or is coated with stamp-pad ink, adds cost of labor undoubtedly, according to current every mu Average 100 works of the tobacco hybridization production of hybrid seeds are calculated, and Gansu cost of labor every day average price is 150 yuan of every days, and accumulative cost of labor is 15000 Unit, cost of labor is higher.

2, production cost improves, the most general nylon wire just used or plastic hoop, by 0.03 yuan every, and every strain Pollinating 20 flowers, every mu of 4000 strains, cost is about 2400 yuan, relatively costly.

3, labelling accuracy rate is big by man's activity, by bolt line or band, in practical operation, by artificial limbs By touching, or in Nicotiana tabacum L. maturation picking process, it is likely to there will be and comes off, and be coated with stamp-pad ink, sprayed insecticide by field, or Person is rained and labelling can be made slowly to come off, it is impossible to truly judging whether pollination, affect the accuracy rate of the production of hybrid seeds, remote-effects seed is pure Degree.

Summary of the invention

It is an object of the invention to provide a kind of tobacco hybridization production of hybrid seeds labeling method, it is not required to bolt line, band or is coated with stamp-pad ink Just can be marked, low cost, accuracy rate is high.

In order to solve the problem in the presence of background technology, the present invention is by the following technical solutions:

After tobacco hybridization seed production and pollination terminates, first pinch the anthocaulus of pollination flower with left hand, then with the right hand laterally from root Portion removes two pieces of sepals, and action wants slim and graceful.

Beneficial effects of the present invention following points:

1, cost of labor is low, and every mu of Nicotiana tabacum L. production of hybrid seeds can save 30 works of cost of labor, by the most artificial 150 yuan, can directly save 4500 yuan.

2, production cost is low, the raw material that conventional labeling method is used, and using all need not, directly saving 2400 Unit.

3, labelling accuracy rate is high, has uniqueness, by the method removing sepal, during the whole production of hybrid seeds of Nicotiana tabacum L. until Plucking, labelling is all without elimination, it is ensured that seed production purity.

Detailed description of the invention

A kind of tobacco hybridization production of hybrid seeds labeling method, its detailed description of the invention and principle are as follows:

Sepal removes the principle of labeling method: understands the technical scheme of sepal removal method, first has to learn about Nicotiana tabacum L. sepal Structurally and functionally, the sepal of Nicotiana tabacum L. mainly has 5-7 sheet oval shape, wraps up petal, has a small amount of thorn villous to cover, sepal With petal the flowers are in blossom put before there is the function of protection flower internal structure, containing multiple chemical substance, such as flavone inside sepal Constituents, visible special fluorescence under the specific wavelengths such as ultraviolet light, this fluorescence can attract and guide corresponding insecticide to come Sucking Hua Mi, thus assist propagation pollen, the sepal of Nicotiana tabacum L. is unless artificial removal has being permanently present property, and this is also that we use No matter the cardinal principle of sepal removal method, start until the ripe harvesting of Nicotiana tabacum L. from being formed of flower, and sepal is in whole growth Growth course all can be permanently present, and there is uniqueness.

Sepal removes the operational approach of labeling method: we typically, during tobacco hybridization seed production and pollination, choose second The flower emasculation that it can open, the next morning, the flowers are in blossom put after pollinate, pollination terminates, it is necessary to make marks, and first needs Pinch the anthocaulus of pollination flower with left hand, laterally remove two pieces of sepals with the right hand, quick and graceful in the movements, need to be grasped dynamics, this Individual method it is to be noted that first, must laterally remove, it is impossible to longitudinally, because whole flower may be damaged； The second, can not nip off sepal, because sepal also can be able to increase along with expanding of Nicotiana tabacum L., the sepal nipped off also can increase, for the later stage Judgement bring difficulty；3rd, need to remove two pieces of sepals, if only removing one piece, along with expanding of Nicotiana tabacum L., relaxing of sepal Exhibition, can cause labelling between sepal inconspicuous, and impact judges, tears sepal except increasing workload and increasing flower wound more Outward, the most more act on, so it is best to remove two pieces of sepals.

Claims (1)

1. a tobacco hybridization production of hybrid seeds labeling method, its technical scheme is as follows:

After tobacco hybridization seed production and pollination terminates, first pinch the anthocaulus of pollination flower with left hand, then with the right hand laterally from root Portion removes two pieces of sepals, and action wants slim and graceful.
