Description
Technical field
The present invention relates to a kind of screening technique of japonica rice variety.
Background technology
More than 400 ten thousand mu of the existing salt-soda soil paddy field of West in Jilin Province, accounts for more than the 30% of the whole province's paddy field area, its yield and product
The Rice Production of confrontation the whole province is held the balance.As Soda saline and alkaline soils alkalescence mineral element Na contents are high, contain again a certain amount of
K, Ca, Mg etc.；Contain substantial amounts of CO simultaneously3 2-And HCO3 -, which produces substantial amounts of OH after hydrolyzing-, pH height, to rice yield and product
Matter produces material impact.
Oryza sativa L. is the staple food of more than 60% population of China, and the alkaline mineral element in rice has many benefits to the health of people.
The plantation place of production directly affects rice Mineral Elements content, and rice Mineral Elements with soil Mineral Elements species and
The change of content and change, be often such as grown in Oryza sativa L. in Saline-Sodic environment containing more mineral elements, and Oryza sativa L. be not
Also there were significant differences for absorption of the homogenic type to soil Mineral Elements.Such as, 49 Oryza sativa L. that plants in Cr contaminated soils
Strain, in brown rice, the content of Cr has 23 times of difference.
In human body, weakly alkaline environment is the important symbol of human health, and maintains internal alkalescence to depend on people institute
The food that eats.In general containing more foods of mineral such as Na, K, Ca, Mg, enter in human body and Na is generated through digestion and metabolism2O、
The basic anhydride such as KO, CaO, MgO, final metabolite are conducive to human health often in alkalescence.Therefore, screening absorbs profit
With the alkaline element content such as K, Na, Ca, Mg is high, weakly alkaline North Japonica Rice kind is to realize that the upgrading of soda alkaline land Oryza sativa L. increases
Effect, the most basic material base for making alkaline rice brand.
Content of the invention
The present invention provides a kind of screening technique of alkaline japonica rice variety.Selection-breeding for natural alkaline rice provides basis.
The screening technique of alkalescence japonica rice variety of the invention, comprises the following steps：
First, period of duration 130-135 days high yields, the middle morning-middle-mature stage North Japonica Rice kinds of quality better are extensively collected.
2nd, the japonica rice variety that collects is planted in non-salt-soda soil paddy field, slight soda alkaline land paddy field, moderate Soviet Union respectively
Beat in salt-soda soil paddy field and severe soda alkaline land paddy field, non-salt-soda soil the chemistry of submerged soils property is that pH6.8-7.2, ESP are low
In 2.5%；The soil chemical properties in slight soda alkaline land paddy field is pH8.3-8.5, ESP14%-16%；Moderate Saline-Sodic
The soil chemical properties in ground paddy field is pH8.5-8.8, ESP24%-26%；The chemical property of heavy salinized ground paddy field soil is
PH9.0-9.3, ESP39%-41%.
3rd, more than 10 square metres of each kind plantation plot area, 3 repetitions, random district's groups arrangement, fertilizer, water management are same
Locality, artificial hand rice transplanting, 16.7 centimetres of 30 cm x of seeding row spacing, per cave 3-4 Seedlings, on the growth period record heading date, autumn is each
Cell is received full survey and is produced, and all cells sample species test, and meansigma methodss of the species test result according to plantation cell species test select effective tillering
The kind of 20-22, number of grain per ear 100-120 grains, setting percentage more than 90% and 23-25 gram of mass of 1000 kernel, is then screened wherein
Go out the minimum japonica rice variety 3～5 of underproduction amplitude.
4th, the japonica rice variety obtained for step 3 screening, the brown rice yield of each kind of measure, head rice rate, amylose
Content, gel consistence and chalkness ratio, each kind Cooking Quality of appraise are more than more than 77.0%, head rice rate according to brown rice yield
62.0%th, amylose content 15.0-20.0%, gel consistence are more than 60 millimeters, chalkness ratio are less than 30% and Cooking Quality is more than 7
The standard that divides is selected.
5th, the japonica rice variety obtained for step 4 screening, carries out detection and the pH of K, Na, Ca and Mg alkaline element content
Value is determined, and filters out the cumulative content highest of alkaline element, and pH value is 7～8 japonica rice variety, as alkaline japonica rice variety.
The evaluation methodology of Cooking Quality described in step 4 is with reference to National Standard of the People's Republic of China《High quality paddy》GB/
T17891-1999.
Beneficial effects of the present invention：
There is significant difference in soda alkaline land paddy planting to alkaline element enrichment according to different rice varieties in the present invention
Rule, in comparative study difference Rice Yield, quality and each organ of Oryza sativa L. the constituent content such as K, Na, Ca, Mg it
Between mutual relation, with reference to the concept of basic food, filter out that the constituent contents such as K, Na, Ca, Mg are high and yield and quality substantially not
The natural alkaline rice rice special new varieties for becoming.
The inventive method is simple and easy to do, and the rice varieties for screening have good nutritional health function.
