Description

The breeding method of a kind of high protein, homovitamin C content radish seed bud dish
Technical field
The present invention relates to a kind of breeding method of radish seed bud dish, particularly relate to the breeding method of a kind of high protein, homovitamin C content radish seed bud dish, belong to agricultural production, raw-food material production field.
Background technology
Bud class is traditional high quality food that compatriots like.The food that bud-genus food refers generally to cereal, beans produces through germination, commonly moyashi, mung bean sprouts.The nutritive value of bud dish is higher, because its vegetative period is short, does not need fertilising, just can harvest well without the need to laxative, is non-harmful vegetables.Radish seed, another name SEMEN RAPHANI, trailing plants white chessman, dish chieftain, Latin literary fame SemenRaphani. is the mature seed of crucifer radish, is used for the treatment of retention of food and drink, abdominal distention, constipation, stagnant rushes down dysentery, phlegm stops up and breath with cough.Containing abundant nutriment in radish seed bud dish, vitamin content is equivalent to 10 times of Chinese cabbage.Radish seed bud dish is slightly with pungent taste, edible very easy, therefore can go deep into rapidly general family, and the most important thing is that it can water planting, plantation is convenient.In recent years, people like adding bud dish eating in barbecue, western-style food or salad, not only good to eat but also nutrition.As at taste noise juice or add ternip seedling with meat and nurse one's health in the lump, not only can promote gastrointestinal disturbances, and can eliminate greasy.
Summary of the invention
The object of the present invention is to provide the breeding method of a kind of high protein, homovitamin C content radish seed bud dish, radish seed germination condition is screened, to increase radish seed germination rate, improve albumen, the vitamin content of radish seed bud dish, to provide high-quality radish bud dish.
For achieving the above object, the present invention is by the following technical solutions:
A breeding method for high protein, homovitamin C content radish seed bud dish, the method comprises the following steps:
(1) select culture medium: take vermiculite as culture medium, load in nutrient discs, the thickness of vermiculite is 5-7cm;
(2) choose seeds: select fresh full radish seed, used 50-55 DEG C of emerge in worm water 15min, pull out, then soak 15min with 1% liquor potassic permanganate, pull out, clear water washes 2 times;
(3) sow: by seed uniform broadcasting in matrix, cover vermiculite 1.5-2.0cm;
(4) add culture fluid: milk is mixed with the 0.5-2g/L aqueous solution, pours milk soln into culture matrix, humidity is agglomerating to hold with hand, and namely stretching out one's hand falls apart is advisable;
(5) manage: cultivate 5-7 days in 20-30 DEG C, gather in the crops.
The present invention selects vermiculite to be culture matrix, and vermiculite is a kind of natural, nontoxic mineral matter, dilatable mineral under high temperature action.Because vermiculite has the ability of ion exchange, it has great effect to the nutrition of soil.Vermiculite can promote the stable growth of the growth of root system of plant and seedling effectively.The necessary moisture of plant growth and nutrition are provided for a long time, and the stable of plant root temperature can be kept.Vermiculite can make crop just can obtain sufficient moisture and mineral matter from early growth period, promotes that plant comparatively fast grows, increase yield.
Preferably, described nutrient discs is placed on semi-enclosed layer stereo support, and so-called semi-enclosed layer stereo support is three side sealing and closes, the layer stereo support that top, bottom and operating surface are exposed.This semi-enclosed layer stereo support, both for putting multilayer seedling dish, carries out vertical cultivation, both can improve and utilize space, cost-saving, contributes to again keeping certain humidity.
Preferably, the humid control of the middle culture matrix of described step (4) is at 50-60%.
Preferably, the concentration of the aqueous solution of described milk is 1g/L; In described step (5), cultivation temperature is 20 DEG C, and incubation time is 7 days.
The present invention breaches the traditional mode of production pattern of radish seed (SEMEN RAPHANI) bud dish, has initiated and has utilized simple machine to carry out novel standardization intensive production new model under severe conditions.Beneficial effect of the present invention is:
1, the present invention is suitable for intensive cultivation high protein, homovitamin C content radish seed bud dish.
2, present invention process feasibility is strong, is not affected by the external environment, without chemical fertilizer, hormone and agricultural chemicals in the production process of shoot vegetable.
3, the present invention place used and nutrient solution cost low, invest little, instant effect, growth cycle are short, output is high, added value of product is high, can be used for the batch production of bud dish, intensive manufacture.
4, the Product Safety adopting the present invention to cultivate is high, and environmentally safe, has really met people to demand that is natural, nuisanceless, high-quality, to the yearning of pure life, is the green organic products meeting current era meaning.
Embodiment
Below by way of specific embodiment, the present invention will be further described.
The mensuration of protein content and the mensuration of Vitamin C content adopt following methods respectively in the examples below.
1, protein content is measured with Coomassie Brilliant Blue
(1) preparation of standard liquid: accurately take bovine serum albumin(BSA) 100.00mg, distilled water dissolves, and be settled to 1000mL, this is 0.1g/L protein standards storing solution, Refrigerator store.
(2) preparation of Coomassie brilliant G-250 solution: precision takes Coomassie brilliant G-250 100.00mg, adds 95% ethanol 50mL (blueness), then adds 85% (W/V) H 3pO 4100mL (blood red) is finally settled to 1000mL (brown) with distilled water.
(3) preparation of need testing solution: take drying sample 0.5g, adds a small amount of quartz sand distilled water and grinds to form homogenate and be settled to 100mL, and leave standstill 10-30min (3-5min, shake once) and filter, it is for subsequent use that filtrate is settled to 100mL.
(4) Specification Curve of Increasing: standard liquid 1mL, after adding Coomassie brilliant G-250 protein reagent, shakes up, after placing 2min, and colorimetric estimation under 595nm wavelength, record A595.With protein content (X) for abscissa with absorbance (A) for ordinate carries out linear regression analysis, equation of linear regression is: A=1.565X-0.005, coefficient R 2=0.999.
(5) sample size measures: get 2, test tube, 1 the preparation 1mL liquid to be measured adding need testing solution, and 1 adds 1mL distilled water (doing blank), add 5.0mL Coomassie brilliant G-250 reagent again, shake up, after placing 5min, colorimetric under 595nm wavelength, record A595.By Specification Curve of Increasing operation, measure absorbance, record data, calculate protein content.
2, the mensuration of Vitamin C content
The drafting pipette of calibration curve draws 1g/L vitamin C titer 0.00mL, 0.20mL, 0.40mL, 0.60mL, 0.80mL and 1.00mL respectively to 6 clean 50mL test tubes, be settled to scale, with 0.00mL vitamin C mark liquid for blank makes reference, under 267nm wavelength, use 1cm quartz colorimetric utensil, measure absorbance.With the mass concentration of vitamin C serial solution for abscissa, with the absorbance of correspondence for ordinate, draw out calibration curve.Data are carried out recurrence process, result shows, ascorbic mass concentration is linear within the scope of 0 ~ 20mg/L, and equation of linear regression is: A=0.06163X-0.02934, coefficient R 2=0.998.
3, ascorbic extraction and mensuration in radish seed sample
Cleaned by bud dish, drain, chopping, mixing, accurately take 10g respectively in grinding alms bowl, add the hydrochloric acid of 10mL1%, homogenate moves in 50mL volumetric flask, with distilled water diluting to scale.Accurate measuring 1mL extract respectively, wherein 1mL puts into the 50mL test tube filling 2mL10% hydrochloric acid, measures it in 267nm place absorbance.Vitamin C content is calculated by calibration curve.
Embodiment
