CN104855276A - Watermelon hybrid seed production marking method - Google Patents

Abstract

The invention provides a watermelon hybrid seed production marking method, relating to the technical field of watermelon hybrid seed production. The method is characterized by firstly pinching a stalk of a pollinated flower with a left hand and then horizontally tearing off two sepals from the root with a right hand after pollination for watermelon hybrid seed production is finished, wherein the movement is light and graceful. The method can be used for marking without using threads, rings or oil, is low in cost and has high accuracy.

Description

A kind of production of watermelon hybrid seeds labeling method

Technical field

The present invention relates to production of watermelon hybrid seeds technical field, particularly relate to a kind of production of watermelon hybrid seeds labeling method.

Background technology

Production of watermelon hybrid seeds, in order to improve seed production purity, prevent mixed adopt or people for mixing, the method made marks after generally all adopting pollination, like this in whole production of hybrid seeds process, the seed production purity that can effectively control to cause because of artificial or other factors is inadequate, thus bring loss to seeding farmer and manufacturer, therefore the method for hybrid seeding mark is adopted, the general production of watermelon hybrid seeds labeling method just adopted of current world-class company is bolt line or band, or adopt and be coated with stamp-pad ink, mark obviously, but also there is certain defect in this kind of method, mainly following point:

1, cost of labor is high, adopts bolt line or band, or is coated with stamp-pad ink, add cost of labor undoubtedly, according to every mu of average 100 works calculation of production of watermelon hybrid seeds at present, Gansu cost of labor every day average price is 150 yuan of every days, accumulative cost of labor is 15000 yuan, and cost of labor is higher.

2, production cost improves, and is no matter the general nylon wire that just uses or plastic hoop now, and by every only 0.03 yuan, every strain is pollinated 20 flowers, and every mu of 4000 strains, cost is about 2400 yuan, and cost is higher.

3, accuracy rate is marked large by man's activity, by bolt line or band, in practical operation, by artificial limbs by touching, or in the ripe picking process of watermelon, all likely there will be and come off, and be coated with stamp-pad ink, sprayed insecticide by field, or raining all to make mark slowly come off, truly cannot judge whether pollination, affect the accuracy rate of the production of hybrid seeds, remote-effects seed purity.

Summary of the invention

The object of this invention is to provide a kind of production of watermelon hybrid seeds labeling method, it does not need bolt line, band or is coated with stamp-pad ink just can mark, and cost is low, and accuracy rate is high.

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

After production of watermelon hybrid seeds pollination terminates, first pinch the anthocaulus of pollination flower with left hand, then laterally remove two pieces of sepals from root with the right hand, action wants slim and graceful.

Beneficial effect following points of the present invention:

1, cost of labor is low, and every mu of watermelon production of hybrid seeds can save cost of labor 30 works, by often artificial 150 yuan, can directly save 4500 yuan.

2, production cost is low, in the past the raw material that adopt of labeling method, will all not need to use, directly saving 2400 yuan.

3, mark accuracy rate high, have uniqueness, by removing the method for sepal, until pluck in the whole production of hybrid seeds process of watermelon, mark all can not be eliminated, and ensure that seed production purity.

Embodiment

A kind of production of watermelon hybrid seeds labeling method, its embodiment and principle as follows:

Sepal removes the principle of labeling method: the technical scheme understanding sepal removal method, first structure and the effect of watermelon sepal will be learnt about, the sepal of watermelon mainly contains 5-7 sheet oval shape, parcel petal, there is a small amount of thorn and villous covering, sepal and petal the flowers are in blossom put before there is the function protecting flower interior, containing number of chemical material inside sepal, such as flavones ingredient, fluorescence special as seen under the specific wavelengths such as ultraviolet light, this fluorescence can attract and guide corresponding insect to come to suck Hua Mi, thus auxiliary propagation pollen, the sepal of watermelon removes non-artificial removal and has permanent existence, this is also that we adopt the cardinal principle of sepal removal method, no matter from the formation of flower until the harvesting of the maturation of watermelon, sepal all can forever exist in whole growth and development process, and there is uniqueness.

Sepal removes the method for operating of labeling method: we are generally in production of watermelon hybrid seeds pollinating process, choose the flower emasculation that can open for second day, the next morning, the flowers are in blossom put after pollinate, pollination terminates, just need to have made marks, first the anthocaulus pinching pollination flower with left hand is needed, laterally two pieces of sepals are removed with the right hand, quick and graceful in the movements, need to be grasped dynamics, this method it is to be noted that first, must laterally remove, can not be longitudinal because may damage whole flower; The second, can not nip off sepal, because sepal also can be able to increase along with expanding of watermelon, the sepal nipped off also can increase, for the judgement in later stage brings difficulty; Three, need to remove two pieces of sepals, if only remove one piece, along with expanding of watermelon, unfolding of sepal, can cause mark between sepal not obvious, impact judge, tear sepal except increasing workload and increasing except flower wound more, more do not act on, so it is best to remove two pieces of sepals.

Claims (1)

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

After production of watermelon hybrid seeds pollination terminates, first pinch the anthocaulus of pollination flower with left hand, then laterally remove two pieces of sepals from root with the right hand, action wants slim and graceful.
