Abstract
A kind of method that quick subculture of paddy rice is bred, breeding place is that 5~September part is completed in continent with the time, and the April in October to next year, the rational arrangement time was bred with place in Hainan.In cultivating process, every plant is only stayed a tiller, unnecessary tiller to remove at any time, compare with field planting to rice seedling, can shorten breeding time 10~13 days.Heading is cut clever test cross each single fringe and only stays 30~50, middle part, and unnecessary grain is all removed, and promotes hasting of maturity, to be cut break tassel within 13~15 days after grain husk and is pushed down into 3~5 days i.e. vertical buds in mud, compared with the conventional method, can shorten breeding cycle 15~18 days.It is pressed into mud with whole tassel, does not produce threshing to give birth to, do not produce dormancy, fringe bar persistently can also supplies nutrient to grain, and grain speed of germination is fast, and plant strain growth is healthy and strong.By implementing the present invention, the generation time of infertility can shorten 30 days or so compared with traditional mating system, effectively reduce breeding risk and breeding cost.
Description
Technical field
The present invention relates to rice breeding technology field, and in particular to the method that a kind of quick subculture of paddy rice is bred.
Background technology
At present, traditional paddy rice mating system mainly has as follows：
(1) seed selection breeding：Sowing → seedling → cultivate → select excellent.
(2) crossbreeding：Sowing → seedling → cultivation → hybridization.
(3) mutation breeding：Sowing → seedling → cultivation → variant.
Above-mentioned several mating systems, being required for being bred after the subculture in 8 seasons to 12 seasons (4-6) could obtain the water of stabilization
Rice varieties.And breeding cycle (generation time of infertility) needs more than 140 days, breeding time is long, virtually increased breeding wind
Danger and breeding cost.
The content of the invention
The purpose of the present invention overcomes the shortcomings of above-mentioned technology and provides a kind of brand-new quick subculture of paddy rice and breed
Method.Specifically include：Breeding place and time → sowing cultivation → nursery → breed.
The present invention is achieved through the following technical solutions：
A kind of method that quick subculture of paddy rice is bred, comprises the following steps in technical scheme：
1st, breeding place and time：5~September part is arranged in the south completion in continent, and the April in October to next year is arranged in
Hainan completes.
2nd, sowing is cultivated：Sun-drenched place is selected, fertile soil is filled with water vat, breeding millet is carried out into vernalization, with
10cm's is sown into cylinder apart from simple grain point, and blinding is defined by burying husk, while keeping ground moistening for a long time, and to avoid table
Layer dew.
3rd, nursery：When the germination in cylinder and after seedling is grown, every plant is only stayed a tiller, unnecessary tiller to remove at any time,
Then cultivate to rice seedling heading, after rice seedling heading, clever test cross is cut into heading, each single fringe only stays 30-50, middle part, and unnecessary grain is complete
Portion is removed, and promotes grain hasting of maturity.
4th, breeding：Tassel was broken down in 13-15 days after cutting grain husk, then vernalization is carried out in whole tassel press-in mud, 3~5 days are just
Start vertical bud, then proceed to the above-mentioned technique of repetition and bred.
The present invention both had the following advantages：
1st, the quick subculture of paddy rice proposed by the invention is bred method is novel, method and measure is unique, process is simple, holds
Easily implement.
2nd, by implementing the present invention, breeding place is with the time：5~September part is completed in continent, the April in October to next year
Part is in Hainan.The rational arrangement time is bred with place, realizes that whole year can carry out input and breed, and fully and is reasonably utilized
Time.
3rd, by implementing the present invention, in cultivating process, every plant is only stayed a tiller, unnecessary tiller to remove at any time to rice seedling,
Compared with field planting to beginning fringe with this method, breeding time can be shortened 10~13 days.
4th, by implementing the present invention, heading is cut clever test cross each single fringe and only stays 30~50, middle part, and unnecessary grain is all removed,
Promote hasting of maturity, to cut break tassel within 13~15 days after grain husk to be pushed down into mud and found bud in 3~5 days, compared with the conventional method, can contract
Short breeding cycle 15~18 days.
5th, by implementing the present invention, it is pressed into mud with whole tassel, does not produce threshing to give birth to, do not produce dormancy, fringe bar may be used also
Persistently to supply nutrient to grain, grain speed of germination is fast, and plant strain growth is healthy and strong.
6th, by implementing the present invention, the generation time of infertility is 98~105 days or so, and just traditional mating system is compared and used
This technology can shorten breeding cycle 30 days or so, effectively reduce breeding risk and breeding cost.
Specific embodiment
The method of the present invention is further illustrated with reference to embodiment.
A kind of method of paddy rice rapid breeding, specific embodiment is as follows：
1st, breeding place and time：5~September part is arranged in the south completion in continent, and the April in October to next year is arranged in
Hainan completes.
2nd, sowing is cultivated：Sun-drenched place is selected, fertile soil is filled with water vat, breeding millet is carried out into vernalization, with
10cm's is sown into cylinder apart from simple grain point, and blinding is defined by burying husk, while keeping ground moistening for a long time, and to avoid table
Layer dew.
3rd, nursery：When the germination in cylinder and after seedling is grown, every plant is only stayed a tiller, unnecessary tiller to remove at any time,
Then cultivate to rice seedling heading, after rice seedling heading, clever test cross is cut into heading, each single fringe only stays 30-50, middle part, and unnecessary grain is complete
Portion is removed, and promotes grain hasting of maturity.
4th, breeding：Tassel was broken down in 13-15 days after cutting grain husk, then vernalization is carried out in whole tassel press-in mud, 3~5 days are just
Start vertical bud, then proceed to the above-mentioned technique of repetition and bred.
By implementing the present invention, the seed combination other technologies measure of acquisition is reapplied in producing following effect in production：
(1) after by the germination of the wild saline and alkaline rice in Java, take focused solar energy to radiate and produce variation, select plant and leaf shape
Good, the advantage individual plant of strong stress resistance is utilized.Exist as April in this year provides saline and alkaline rice by Lingshui Chong Xue radioactive breeding research institute
The Dongying in Shandong, the Lingshui in Hainan, plant experimentally on salt-soda soil and have succeeded, about 400 kilograms of per mu yield.
(2) after Bath horse base of a fruit original seed is germinateed, solar radiation is focused, the difference individual plant backcrossing of seed selection advantage is obtained
The kind that plant and leaf shape is good, rice is of fine quality, yield stability good, absorption selenium zinc function is strong is obtained, industry input selenium zinc rice is planted in Chongqing emperor China
3 years (2014-2016) first-class qualities of production.
(3) the loyal perfume A that the Bath horse base of a fruit seed for obtaining is cultivated by focused solar energy radiation, miscellaneous by Purity
Hand over combination popularization and application, the species the advantage：Matter is good for rice, head rice rate is up to 63~75%, yield stability, strong stress resistance and high temperature resistant.
(4) seed obtained by the present invention using the saline and alkaline wild rice in Java, selects excellent using focused solar energy radiation, returns
Hand over, the two-line sterile line for cultivating Salt And Alkali Tolerance in 2 years, being named as " learning S again " will identify and the popularization and application in production.
