Abstract
The invention discloses a parent seed reproduction method for anther kale with pollen difficult to scatter. The method includes the following steps that (1) a hole tray is selected to conduct sowing and seeding cultivation at the end of summer and in the beginning of autumn; (2) transplanting and planting are conducted, and when the kale seedling grows four leaves and one center, the kale is planted in the field; (3) old leaves are removed; (4) parent breeding is conducted, wherein when the kale produces shoots, blooms and begins to conduct bud pollination, the flower bud going to bloom of a plant B special for pollen collection is cut off by 31% to 35%, the stigma of a plant A is peeled and exposed out through a nipper the next day, the day before collection, the pollen of the plant B is smeared on the peeled stigma of the plant A, and the cycle is repeated till the parent pollination is finished. The parent seed reproduction method for the anther kale with the pollen difficult to scatter is simple and easy to operate, saved labor is more than doubled, the pollen quality is high and the fructification percentage is more than doubled. According to the parent seed reproduction method for the anther kale with the pollen difficult to scatter, during bud pollination, people do not need to go around to search for the pollen or to scrape the anther with the nipper to take the pollen, and thus pollen collection is easy and convenient and time is saved in seed reproduction.
Description
Technical field
The present invention relates to the breeding method of a Plants, especially a kind of for not parent's breeding method of affine kale of selfing of loose powder of flower pesticide, belong to field of plant growing technology.
Background technology
Kale has another name called colored cabbage, leaf tree peony, color leaf wild cabbage, is that Cruciferae wild cabbage belongs to biennial herb flowers.Originate in Mediterranean, Britain, Holland, Germany, Japan and U.S.'s plantation are more, all over the world widely cultivation.China is since the 90's of 20th century introducing and planting, and the south of the lower reaches of the Yangtze River is cultivated comparatively generally as the ground such as Shanghai, Hangzhou, and North China and the Northwest introduce gradually, and the Northeast is still in the introduction and Experiment stage.
Kale as herbage flower is leaf attractive in appearance changeable, and lobus cardiacus rich color is gorgeous, and viewing period is 4 months, is to beautify late fall, early winter and the comparatively desirable green plants of cold season flower bed in early spring, also can potted plant sight leaf or make cut-flower and sell.
Kale parent propagation adopts bud pollination more, and wherein not loose powder or difficult loose powder of some parent material flower pesticide, causes the column cap difficulty stripping out to find pollen to be coated with up, parent propagation difficulty.When bud pollination, because of the extremely difficult loose powder of flower pesticide that this parent is normally bloomed, need in plant, find the flower of flower pesticide loose powder, this need to spend the plenty of time, and is often difficult to find.Really not when loose powder with tweezers not loose powder flower pesticide scratch, then pollen is spread upon on the column cap stripping out, because the pollen humidity scraping is larger, ripening rate is low.
Summary of the invention
The object of the present invention is to provide a kind of easy operating, can make difficult loose powder flower pesticide kale be convenient to the method for parent propagation.
The present invention is achieved by the following technical programs:
Parent's breeding method of difficult loose powder flower pesticide kale, comprises the following steps:
1) sowing
Autumn late summer primary election one place levels land and does seedbed, and uniform spreading one deck matrix on seedbed is selected cave dish seeding and seedling raising after watering;
2) transplant planting
Sow after one month, kale seedling grow four leaves wholeheartedly time field planting in land for growing field crops, apply the person poultry muck of becoming thoroughly decomposed, many field planting part plant are used as to get specially powder, carry out conventional field management;
3) Lao Ye removes
After transplant planting half a year, when kale bolting, remove base portion Lao Ye, Huang Ye, effectively prevent that plant from rotting;
4) parent propagation
Bloom and start when bud pollination at kale bolting, many field planting part is got to the plant B that pollen uses specially and mark, the plant that all the other breedings are used is plant A;
Pollination afternoon before that day, the bud that 4-5 bud on each plant B branch of having bloomed is about to bloom cuts off 31-35%, the bud that with tweezers, plant A is about to bloom for second day carefully strips out column cap, adopt the bud of the loose powder of blooming that plant B cut with scissors the previous day, break flower pesticide and its pollen is spread upon on the column cap that plant A strips out; Then and continue bud that plant B is about to bloom and cut off again 31-35%, give over to second day and pick flowers powder use, so circulation end until parent pollinates.
Object of the present invention can also further realize by following technical measures.
Parent's breeding method of aforesaid difficult loose powder flower pesticide kale, wherein in step 4) according to this parent's anther length, flower pesticide is cut to 33%-50%.
Parent's breeding method of aforesaid difficult loose powder flower pesticide kale, wherein the quantity of plant B is 10% of plant A quantity.
The present invention is simple, saving of labor is more than one times, and pollen quality is high, and ripening rate doubles above.The bud that the present invention is about to the female parent of kale to bloom cuts off 33% left and right with scissors, and after within second day, blooming, loose powder is normal.In the time carrying out bud pollination, do not need to look for powder everywhere, do not need to scratch flower medicine powder taking with tweezers yet, get powder simple, convenient, breeding saves time.
Advantage and disadvantage of the present invention, will make an explanation by the non-limitative illustration of preferred embodiment below, and these embodiment only provide as an example.
Embodiment
After blooming below in conjunction with Jurong City of Jiangsu Province, the invention will be further described for No. 6 maternal embodiment of auspicious plumage of the difficult normal loose powder of flower pesticide.
The step of the present embodiment is as follows:
1) sowing
Autumn late summer primary election one place levels land and does seedbed, and uniform spreading one deck matrix on seedbed is selected cave dish seeding and seedling raising after watering;
2) transplant planting
Sow after one month, kale seedling grow four leaves wholeheartedly time field planting in land for growing field crops, apply the person poultry muck of becoming thoroughly decomposed, field planting 110 strains altogether, 100 strains are for breeding, 10 strains, for getting powder specially, are carried out conventional field management;
3) Lao Ye removes
After transplant planting half a year, when kale bolting, remove base portion Lao Ye, Huang Ye, effectively prevent that plant from rotting;
5) parent propagation
Bloom and start when bud pollination at kale bolting, many field planting 10 strains are got to the plant B that pollen uses specially and mark, the 100 strain plant that all the other breedings are used are plant A,
Pollination afternoon before that day, the bud that 4-5 bud on each plant B branch of having bloomed is about to bloom cuts off 33%, the bud that with tweezers, plant A is about to bloom for second day carefully strips out column cap, adopt the bud of the loose powder of blooming that plant B cut with scissors the previous day, break flower pesticide and its pollen is spread upon on the column cap that plant A strips out; Then and continue bud that plant B is about to bloom and cut off again 33%, give over to second day and pick flowers powder use, so circulation end until parent pollinates.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent deformation one-tenth, all drop in the protection domain of requirement of the present invention.
