Description
Technical field
The invention belongs to agriculture seedling technical fields, and in particular to a kind of primary tomato seed breeding method.
Background technology
Tomato also known as tomato, tomato；In Peru and Mexico, initially it is referred to as " wolf peach ".The fruit battalion of tomato
Support abundant, tool flavour.It can eat raw, cook, being processed into catsup, tomato juice or whole fruit canning.Tomato is the whole world
One of cultivation fruit and vegetable the most universal, are mainly planted using establishment planting technologies such as greenhouses, are generally planted all over China,
Cultivated area still is continuing to expand.
Nowadays tomato has been one of most commercialized vegetables, in order to improve the commodity rate of tomato, the tomato planting chamber of commerce adopts
With the kind that fruit is hard, late-maturing, loss of the tomato in transportational process is reduced.Such tomato fruit type is graceful, bright-colored, still
Mouthfeel is poor when eating raw.The tomato variety of Commercial Growers is mainly grafting, and grafting, as stock, is grafted excellent using wax gourd seedling
The tomato variety terminal bud scion of choosing, grafting can improve the disease resistance of tomato plant, accelerate the growth of tomato and ripe speed,
But it can also reduce Tomato Quality.
The content of the invention
In view of the above problems, it is an object of the invention to provide a kind of primary tomato seed breeding method, which is tomato
Seedling, obtained by planting numerous form, the character of plant is excellent, and yield is high, resistance, and fruit mouthfeel is very good.
A kind of primary tomato seed breeding method, includes the following steps：
(1) vernalization
Tomato seeds are sent into refrigerator, 12-18h is handled at a temperature of 0-5 DEG C, then takes out seed, is put naturally
It puts to room temperature is recovered, is then uniformly placed on tomato seeds in the sterile cotton pad soaked using pure water, cotton pad, which is placed on, urges
Bud connects on disk and is sent in germinating box, and the temperature in germinating box keeps 38-42 DEG C between daily 4-15 points, 15-4 points it
Between kept for 25-30 DEG C, ambient humidity control after seed is placed into germinating box for 24 hours, sprays seed promotion rudiment for 70-80%
Growth regulator A, the amount sprayed is 0.6-0.8 times of seed quality, and the bud point broken shell of seedling is simultaneously completely stretched out from kind of shell
Afterwards, seed is taken out from germinating box.
(2) final singling
By in the seedling growing block after moving on to swells from the germinated seeds that germinating box takes out, the seed bud in every seedling growing block
Quantity is 2, and seedling growing block placement is cultivated in the incubator, and gnotobasis is kept in incubator, and temperature control is 18-26
DEG C, humidity 60-85%, every 4-6d to seedling growing block spray on plants nutrient solution, seed bud cultivates 8-15d in seedling growing block, treats kind
Eggplant seedling root system from nursery block edge stretch out when, seedling and seedling growing block are removed together.
(3) seedling is practiced
Seedling growing block and seedling are moved on to from nursery box on nursery basket, nursery basket is placed in common greenhouse-environment, to tomato
Seedling carries out practicing seedling, and it is 10-15d to practice seedling stage, and the 2-4d for practicing seedling stage sprays growth regulator B to seedling cauline leaf and its root,
And first time pinching is carried out to seedling in the 6-8d for practicing seedling stage.
(4) matrix prepares
According to mass fraction：40-50 parts of rural area soil, 30-40 parts of peat soil, 15-20 parts of perlite, 5-10 parts of vermiculite are swollen
Moisten 6-8 parts of soil, each matrix components be uniformly mixed, during mixing into soil addition 400-500 times of dilution of potassium permanganate to soil
Wetting, seedling fostering matrix configures after finishing exposure 1-2d in the sun, spare.
(5) alms bowl is moved
Seedling connection seedling growing block of the white silk seedling after complete is transplanted in pot for growing seedlings together, the compost in pot for growing seedlings uses step
(4) culture medium of configuration is cultivated, the nurturing period, the 10-12d after alms bowl is moved after moving alms bowl in greenhouse, to plant progress the
Secondary pinching moves after alms bowl and cultivates 25-30d and can reach emergence standard and sold.
Preferably, step (1) the growth regulator A be gibberellin and compound sodium nitrophenolate composite solution, gibberellin
Concentration is 80PPM, and the concentration of compound sodium nitrophenolate is 15PPM；The effect of growth regulator A was used in the vernalization phase, and seed is promoted to sprout
It sends out, two plant growth regulators in ingredient are in Seed Germination is promoted, based on gibberellin, supplemented by compound sodium nitrophenolate.
Preferably, the intensity of illumination in germinating box is put into the preceding 5d of germinating box in seed and remains 5-10Lux, 6d
Intensity of illumination is improved to 400-600Lux afterwards, and intensity of illumination is adjusted using fluorescent lamp.In pregermination procedure, early period uses dim light
Rush bud is carried out, intensity of illumination is further added by after bud point is sprouted, so as to promote the synthesis of seed bud inner chlorophyll, improves the life of seedling
Long rate and resistance.
In the present invention, first time pinching is carried out when plant grows 4-6 piece true leaves, and second of pinching grows to 10- in plant
It is carried out during 12cm.The apical dominance of plant can be released during first time pinching, promotes plant thicker, and sprouts two to four newly
Bud, so that plant is more healthy and strong, resistance enhancing, and plant is downgraded, adapt to Commercial Growers, the work of second of pinching
It is controlled plant type with being and strut is promoted to grow, improve the percentage of fertile fruit of plant.
Preferably, the ratio of n-p-k element content is 4 in nutrient solution in step (2):2:3.The nutrient solution is used for
Seedling growth, element ratio therein are mainly to promote the element composition and ratio of plant strain growth.
In the present invention, the line space of every seedling is 5x5cm on nursery basket；The reasonable control in space on nursery basket, can be with
Improve the intensity of illumination of the receiving of plant so that plant plant type is more preferable；And space is efficiently used, reduce nursery into
This.
Preferably, gibberellin, heteroauxin, methyl α-naphthyl acetate and chlorine pyrrole are contained in the growth regulator B in step (3)
Urea, four solution concentration is respectively 10PPM, 25PPM, 40PPM and 20PPM；It is further during the main function of growth regulator B
Promote plant strain growth, and avoid in greenhouse reproductive process, plant section spaced elongate, plant resistance is deteriorated.
A kind of primary tomato seed breeding method provided by the invention, compared with prior art, has the following advantages：
The tomato seedling bred using the method for the present invention, the resistance of seedling can match in excellence or beauty grafting, to various disease pests
Evil has stronger resistance, and plant plant type is short, and lodging tolerance is strong, and branch is more, can improve the percentage of fertile fruit of plant.Most
When important, the fruit mouthfeel which bears is very good, is more suitable for eating raw, and tomato colouring is fast, bright-colored, fresh and sweet more
Juice is applicable to make fruits and vegetables salad.
