Description
Technical field
The invention belongs to field of plant breeding, relate to a kind of corn pollination self method, particularly a kind of corn artificial bagging pollination self method.
Background technology
In corn breeding work, the cultivation of corn inbred line needs a selfing purge process at present.Corn breeding all will carry out a large amount of artificial bagging pollination selfs to selected inbred line material of prior year every year.The bagging work of artificial autocopulation's pollination is the requisite important step of corn breeding.Traditional corn artificial bagging pollination self method, its used paper bag are divided into two kinds in female fringe bag and tassel bag, and female fringe bag is generally made with translucent parchment or template, so that observe the length of female Honoka silk, determine the pollination date.The tassel bag then adopts brown paper to make.
When female fringe exposes and before filigree extracts out as yet, just will in time put female fringe bag to female fringe.Before pollination 1～2 day, can cut off a bit of bract to the female fringe of bagging, neatly extract out to promote filigree, so that fully pollination.
By the time female Honoka silk major part is extracted out, just can carry out bagging to tassel.The process of bagging is: the flower pesticide of the powder that requires will to clear is earlier smoothed out with the fingers with hand, so as not in the paper bag flower pesticide too much, high humidity and influence pollination, be enclosed within the tassel bag on the tassel after, the sack of tassel bag will fold, and packs tightly the base portion of tassel, and is fixed.
To putting the milpa of tassel bag, generally after the next morning, dew was done, when shedding, pollen can pollinate.The step of pollination is: gather tassel pollen earlier, promptly beat the tassel bag that is enclosed within on the tassel with hand, make the pollen on the tassel fall into bag, take off the tassel bag from tassel then.Meanwhile, the female fringe bag that is enclosed within on the female fringe is taken off, immediately the pollen in the tassel bag is invested on the filigree of female fringe, and promptly the tassel bag is enclosed within on the female fringe, the registration of listing at last.
In sum, traditional corn pollination self bagging method, operating procedure is many, and the program complexity if artificial pollination is careless or misoperation, also causing pollination to mix easily.Particularly, during the corn pollination, run into cloudy weather for several days running weather, pollination work just can't be carried out, and has had a strong impact on normally carrying out of corn breeding work, causes the breeding plan in 1 year to fall through.
Summary of the invention
Defective or deficiency at the above-mentioned background technology exists the purpose of this invention is to provide a kind of corn pollination self bagging method, and this method is simple, according to this method selecting and breeding corn inbred line, can prevent that pollination from mixing phenomenon, guarantees pollination quality.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of corn artificial bagging pollination self method, it is characterized in that, this method prepares a kind of pollination bag according to the size of corn breeding material plant type and height, and the size of this pollination bag can be packed the middle and upper part of milpa in the pollination bag into, does not damage maize leaf.
Have a plurality of apertures that are used to breathe freely at the top of pollination bag, also have one deck umbellate form cap at the top of pollination bag, adopt a plurality of adhesion points to be connected between the edge of this umbrella hat and the pollination bag, make to form between the hole at pollination bag top and the umbrella hat and block and air-permeable layer.
When corn is bloomed pollination, in advance pollination bag is enclosed within on the milpa, the bottom of pollination bag is fixed on the corn stem and gets final product.
Adopt method of the present invention, during corn pollination,, when corn is bloomed pollination, can fulfil bagging work ahead of schedule, and when running into adverse weather such as wet weather, can make the normal pollination selfs of breeding material such as corn inbred line owing to adopted pollination bag.This method is original female fringe bag and tassel bag, only substitutes with a pollination bag, just can finish the pollination self process automatically, simplified operating procedure, and general personnel can operate and finish.
Description of drawings
Fig. 1 is pack into schematic diagram in the bag of milpa of the present invention, and wherein the symbol among the figure is represented respectively: 1, pollination bag; 2, milpa; 3, the lower openings of pollination bag; 4, rope; 5, stem stalk; 6, the top aperture of sack; 7, umbrella hat; 8, the adhesion of umbrella hat edge and pollination bag point; 9, female fringe, 10, tassel.
Below in conjunction with embodiment this method is made more detailed description.
Embodiment
According to method of the present invention, prepare a kind of pollination bag 1 by the size of corn breeding material plant type and height, the size of this pollination bag 1 can be packed the middle and upper part of milpa 2 in the pollination bag 1 into, does not damage maize leaf.Have a plurality of apertures that are used to breathe freely 6 at the top of pollination bag 1, also has one deck umbellate form cap 7 at the top of pollination bag, adopt a plurality of adhesion points 8 to be connected between the edge of this umbrella hat 7 and the pollination bag, make to form between the hole 6 at pollination bag top and the umbrella hat 7 and block and air-permeable layer.
Its principle is, when corn breeding material (inbred line) will be bloomed pollination (female fringe 9 exposes and filigree extraction as yet), pollination bag 1 is enclosed within on the milpa 2, and the lower openings 3 usefulness ropes 4 of pollination bag are fixed on the corn stem 5, to prevent to blow pollination bag 1 are wiped off.Secondly, be connected by a plurality of adhesion points 8 between the edge of umbrella hat 7 and the pollination bag 1, umbrella hat 7 is out of shape when preventing to blow, and the aperture 6 at pollination bag top is exposed, and foreign pollen enters in the pollination bag 1, causes pollen to mix.Because the temperature of corn pollinated stage is higher, therefore the opening 3 of the aperture 6 at pollination bag 1 top and bottom forms a gas-circulating system, air can enter from the lower openings 3 of pollination bag 1 in the pollination bag 1, discharge from the aperture 6 at top, because the convection action of hot-air in the pollination bag 1, thereby the rising of temperature in the inhibition pollination bag 1.When air carried out circulative convection, because of action of gravity, pollen was difficult for entering in the pollination bag 1 with air-flow.When tassel 10 loose powder of milpa 2, pollen just descends slowly and lightly automatically to female fringe 9, reaches the purpose of pollination self.Because 7 protections of one deck umbellate form cap are arranged on the aperture at pollination bag 1 top; the lower openings 3 of pollination bag 1 is lower than female fringe 9; so it had both prevented that foreign pollen from entering in the bag; avoided pollen to mix phenomenon; also hindered the immersion of rainwater; can not influence the normal pollination of corn, thereby guarantee the enforcement of pollination quality and annual breeding plan because of wet weather.
Method of the present invention also can be expanded the pollination self of other plant that applies to the different flower of homophyletic.
