Description
Technical field
The invention belongs to agricultural technology field, and in particular to a kind of excellent method of guarantor of odor type Fine Quality Hybrid Rice.
Background technology
Change fragrant 203 strong adaptability and high and stable yield it is good, rice quality is excellent, the sparkling and crystal-clear body of rice thoroughly, four benefit food mouth of delicate fragrance
It is good, it is deep to be liked by peasant household, great function has been played to improving peasant household's kind rice income, kind grain enthusiasm and grain security.
In large area production, the quality of general high-grade rice by growing area ecoclimatic condition, planting technology etc. affect compared with
Greatly.The decay of hybrid rice variety advantage, in addition to being affected by environment and cultivation technique, deteriorating for parent was affected more very on the phase；And
Rice quality is bigger by parent's hereditation.
The content of the invention
For above-mentioned the shortcomings of the prior art, the invention provides a kind of effectively keep Fine Quality Hybrid Rice
The excellent method of guarantor of the odor type Fine Quality Hybrid Rice of the fragrance and head rice rate of Chongqing fragrant 203.
In order to solve above-mentioned technical problem, following technical scheme is present invention employs：
The excellent method of guarantor of odor type Fine Quality Hybrid Rice, including the excellent technology of the extensive 2103 purification guarantor in fragrant 203 parent restorer Chongqing that changes
Fragrant 203 rice harvest and technology is dehydrated with changing；
Extensive 2103 purification in fragrant 203 parent restorer Chongqing of changing is protected excellent technology and is comprised the steps：
1）First Year spring Chongqing：Changing 5-6 breeding time, the plant and leaf shape Comprehensive Traits one of choose in extensive 2103 breeding garden
Cause, the individual plant that blade fragrance is denseer is measured with suitable perfume A sterile lines, while respectively collecting 1 single fringe；
2）Single fringe grain to collecting is peeled off, and leaves 30 or so the brown rice autumns without white belly respectively and carries out plant in Hainan
Breeding, plant division row carry out collecting original seed；It is combined simultaneously and is measured；
3）Hainan aligned the combination being measured in season and was planted autumn, and the advantage of individual plant selected by observation eliminates 1-2 advantage poor
Parent's plant；
4）The matched somebody with somebody combination advantage of 3-4 plant parent that the positive season Chong Qing great areas plantation observation last year Hainan of Second Year stays；
To restorer, parent breeds；
5）With reference to positive season and autumn last year combination advantage, this season parent's breeding time resistance comprehensive condition is evaluated, and final election is received
Take the original seed of 1-2 strain, there is provided next step parent propagation or the production of hybrid seeds are used；Repeat strain selection work above simultaneously；
Fragrant 203 rice harvest that changes is comprised the steps with the technology of dehydrating：
6）During 85% -90% yellow maturity of paddy, take manually or mechanically to change harvesting；It is preferred without dew on paddy during results；
7）The paddy dress bag that millet straw is removed after results is transported to into baking room；
8）The moisture of baking room is adjusted to into 14%, drying temperature is adjusted to 55-60 DEG C, is dried automatically.
As a preferred embodiment of the present invention, the rice drying time in 7-8 hour, rice drying to 14% it is aqueous
Amount.
Compared with prior art, the invention has the advantages that：
1st, fragrant 203 are changed for odor type Fine Quality Hybrid Rice, which protects excellent technology in addition to general Optimum Cultivation, also by strengthening parent
This purification and paddy low temperature hot-air seasoning are keeping the fragrance and rice milling yield of its rice.
1st, the hybrid vigours such as the yield of Chongqing fragrant 203 can be effectively retained by parent's purification.
2nd, the quality heterosis such as the fragrance of fragrant 203 rice that changes are effectively retained.
3rd, effectively improve the head rice rate of fragrant 203 paddy processing that changes.
4th, effectively improve the economic benefit of plantation and processing Chongqing fragrant 203.
Specific embodiment
The excellent method of guarantor of odor type Fine Quality Hybrid Rice, including the excellent technology of the extensive 2103 purification guarantor in fragrant 203 parent restorer Chongqing that changes
Fragrant 203 rice harvest and technology is dehydrated with changing.
Extensive 2103 purification in fragrant 203 parent restorer Chongqing of changing is protected excellent technology and is comprised the steps：
1）First Year spring Chongqing：Changing 5-6 breeding time, the plant and leaf shape Comprehensive Traits one of choose in extensive 2103 breeding garden
Cause, the individual plant that blade fragrance is denseer is measured with suitable perfume A sterile lines, while respectively collecting 1 single fringe.
2）Single fringe grain to collecting is peeled off, and leaves 30 or so the brown rice autumns without white belly respectively and carries out plant in Hainan
Breeding, plant division row carry out collecting original seed；It is combined simultaneously and is measured.
3）Hainan aligned the combination being measured in season and was planted autumn, and the advantage of individual plant selected by observation eliminates 1-2 advantage poor
Parent's plant.
4）The matched somebody with somebody combination advantage of 3-4 plant parent that the positive season Chong Qing great areas plantation observation last year Hainan of Second Year stays；
To restorer, parent breeds.
5）With reference to positive season and autumn last year combination advantage, this season parent's breeding time resistance comprehensive condition is evaluated, and final election is received
Take the original seed of 1-2 strain, there is provided next step parent propagation or the production of hybrid seeds are used；Repeat strain selection work above simultaneously.
Fragrant 203 rice harvest that changes is comprised the steps with the technology of dehydrating：
6）During 85% -90% yellow maturity of paddy, take manually or mechanically to change harvesting；It is preferred without dew on paddy during results.
7）The paddy dress bag that millet straw is removed after results is transported to into baking room.
8）The moisture of baking room is adjusted to into 14%, drying temperature is adjusted to 55-60 DEG C, is dried automatically.
Typically can be the water content of 7 tons or so of rice drying to 14% through 7-8 hour.By " low temperature hot air drying
Chongqing 203 head rice rates of perfume of dry drying " can improve 5-8%, and fragrance is richer.
Compared to the mode " drying of low temperature heated-air drying " that Traditional Man is dried, the rice for not only increasing Chongqing fragrant 203 adds
Work quality, the fragrance for remaining its rice, also significantly improve rice drying efficiency, have saved drying in the air for about 0.06 yuan/kilogram
Cost is shone, and 5-8% is improved by fragrant 203 head rice rate in " drying of low temperature heated-air drying " Chongqing;Using " drying of low temperature heated-air drying "
Technology, is averagely dried 7 tons of paddy per hour, saves and dry 420 yuan or so of cost, and every mu of paddy can save 30 yuan of cost of drying,
Because per mu of the raising of paddy head milled rice can increase income 100-150 it is first.
Finally illustrate, above example is only unrestricted to illustrate technical scheme, although with reference to compared with
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from the objective and scope of technical solution of the present invention, which all should be covered at this
In the middle of the right of invention.
