Abstract
The invention discloses a simple pollination method used in corn breeding. The method comprises the following steps: (1) bagging for isolating corn ears, other than corn tassels, with sulfate paper bags before corn silking; (2) when corn needs pollination after silking and pollen dispersing, pinching the base parts of the corn tassels, swinging the corn tassels left and right with force to remove foreign pollen clinging to the surfaces of the tassels, and then collecting fresh pollen from the corn tassels for pollination; and (3) pollinating the corn ears by the fresh pollen and then fixing the sulfate paper bags by staples for isolating the corn ears. The method with reduced operation steps saves the labor cost of corn breeding and enhances the work efficiency.
Description
Technical field
The present invention relates to the corn breeding techniques field, especially relate to the simple and easy pollinating method of a kind of corn breeding.
Background technology
Corn is the maximum cereal crops of China's cultivated area, and Maize Production has very important strategy function to China's grain security, and corn variety is the basis that ensures Maize Production.Although at present along with technological progress, the means of corn breeding are constantly updated, and artificial pollination remains the indispensable link of corn breeding.Traditional corn breeding artificial pollination need to be carried out the bagging isolation to tassel and female fringe before the corn loose powder is reeled off raw silk from cocoons simultaneously, after pollination, with pin or paper clip, female fringe paper bag is fixed, and not only working procedure is loaded down with trivial details but also article carry inconvenience.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of corn breeding simple and easy pollinating method, reduce operation link, save the cost of labor of corn breeding, increase work efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is: the simple and easy pollinating method of a kind of corn breeding comprises the following steps:
(1) with the sulfuric acid paper bag, maize ear is carried out to the bagging isolation before corn reels off raw silk from cocoons, and maize male ears does not carry out the bagging processing;
(2) while needing to pollinate after corn reels off raw silk from cocoons loose powder, maize male ears is firmly rocked in the base portion left and right that pinches maize male ears with hand, will stick to the lip-deep foreign pollen of tassel and remove, and then with the sulfuric acid paper bag, gets pollen fresh on maize male ears for pollination;
(3) with fresh pollen, maize ear is pollinated, the sulfuric acid paper bag that will isolate maize ear with staple after pollination is fixed.
Preferably, in step (2), if pollinated rapidly after institute's powder of picking flowers, for pollination self, can be adopted powder; If institute's powder of picking flowers is for hybridization, in order to prevent in the pollen carrying process that foreign pollen is sneaked into, adopt after powder need by after the doubling of sulfuric acid paper bag again by the paper bag mouth to infolding
Adopted technique scheme, beneficial effect of the present invention is: the present invention only need carry out the bagging isolation to maize ear, has saved material, and the sulfuric acid paper bag that simultaneously after the pollination, with staple, will isolate maize ear is fixed, staple is light portable, utilizes stapler easy to operate.In sum, with original technology, compare, the present invention can reduce operation link, saves the cost of labor of corn breeding, increases work efficiency.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
Corn reel off raw silk from cocoons front use approximately the sulfuric acid paper bag of 10 centimetres of sizes of 20 cm x by maize ear bagging isolation, during the less bagging of female fringe, the paper bag lower edge is inserted in leaf sheath in case paper bag drops.
Need carry the sulfuric acid paper bag during pollination some, paper bag mouth down while carrying, in case foreign pollen flies into, is fixed on No. 10 staplers on work clothes or wrist by the rubber band elastomeric material, and length is controlled so that be operating as suitable.
When reeling off raw silk from cocoons, the corn loose powder carries out pollination work, pinch the base portion of maize male ears during pollination with hand, double swerve tassel firmly, the foreign pollen sticked on tassel is removed, after removing foreign pollen, with the another hand, rapidly the sulfuric acid paper bag is enclosed within on tassel, then certain angle that tassel tilted, while noting wind is arranged the mouth of sulfuric acid paper bag towards downwind with prevent foreign pollen waft into, fresh pollen is collected in to the middle and lower part of sulfuric acid paper bag with have gentle hands bullet maize male ears.
If pollinated rapidly after institute's powder of picking flowers, for pollination self, can be adopted powder; If pollen for hybridization, adopt after powder need by after the doubling of sulfuric acid paper bag again by the paper bag mouth to infolding, to prevent that in the pollen carrying process, foreign pollen is sneaked into.
After having pollinated, for preventing paper bag, drop, folding by being enclosed within angle of template sack on female fringe, with No. 10 staples, be fixed, to stop space according to female fringe developmental state in the time of fixedly and paper bag be burst when preventing that female fringe from expanding.
Empirical tests, apply technology of the present invention and successively authorized the corn varieties such as Shandong list 981, Shandong list 984, Shandong list 9002, Shandong list 9006, Shandong list 9027, Shandong list 9032, Shandong list 9056, Shandong list 9066, Shandong list 9088, cultivated the Inbred Lines such as 1x9801,1x00-1,1x00-6,1x03-2,1x05-4,1x088.The present invention can reduce operation link, saves the cost of labor of corn breeding, increases work efficiency.
The present invention is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection scope of the present invention.
Claims (2)
1. the simple and easy pollinating method of corn breeding, is characterized in that, comprises the following steps:
(1) with the sulfuric acid paper bag, maize ear is carried out to the bagging isolation before corn reels off raw silk from cocoons, and maize male ears does not carry out the bagging processing;
(2) while needing to pollinate after corn reels off raw silk from cocoons loose powder, maize male ears is firmly rocked in the base portion left and right that pinches maize male ears with hand, will stick to the lip-deep foreign pollen of tassel and remove, and then with the sulfuric acid paper bag, gets pollen fresh on maize male ears for pollination;
(3) with fresh pollen, maize ear is pollinated, the sulfuric acid paper bag that will isolate maize ear with staple after pollination is fixed.
2. the simple and easy pollinating method of corn breeding as claimed in claim 1, is characterized in that, in step (2), if pollinated rapidly after institute's powder of picking flowers, for pollination self, can be adopted powder; If institute's powder of picking flowers is for hybridization, in order to prevent in the pollen carrying process that foreign pollen is sneaked into, adopt after powder need by after the doubling of sulfuric acid paper bag again by the paper bag mouth to infolding.
