Description
Technical field
The present invention relates to vinegrowing technical fields.
Background technique
Grape seed nursery is usually crossbreeding, grow directly from seeds seed selection and when wild resource makees stock utilization through frequently with
Method.Grape seed nursery generallys use soil seeding and seedling raising, nutritive cube seeding and seedling raising, in heliogreenhouse or nursery in greenhouse
Frame hole plate seedling growth.These have the following disadvantages with seedling-growing method, soil seeding and seedling raising: first is that emergence rate is lower；Second is that working as hybridization group
Conjunction number mixes between be easy to causeing combination when more in sowing and transplanting；Third is that because root system is damaged and survival rate when transplanting
It is relatively low, seedling-slowing stage is long, to influence the increment of current year (to encounter hot weather more prominent in transplanting for this problem).And it seeks
Supporting main problem existing for alms bowl nursery is that dress matrix or nutrient bag are relatively taken a lot of work, and put rear out-of-flatness, and emergence rate is relatively
Low, when transplanting, is also easy to mix.Seedling culture frame hole plate seedling growth is time-consuming in the presence of watering in heliogreenhouse or in greenhouse, is entirely educating
Almost need to water everyday between seedling stage, encounter temperature it is higher when, or even daily sooner or later respectively to pour 1 water, slightly carelessness i.e. cause
It cannot emerge or dead seedling.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of new method of Hybrid Grape seed seedling-raising, this method comprises:
By the dried grape hybrid seed plastic film environmental sealing of mature and plump, it is placed in the refrigerator of 1~7 DEG C of temperature and refrigerates 4
Month or more, prior to seeding, take out the Hybrid Grape seed be soaked in 20~30 DEG C 20mg/L~30mg/L gibberellic acid it is molten
6-8 hours in liquid, then Hybrid Grape seed is seeded in the hole tray for filling matrix, 1~2 Hybrid Grape kind of every bunch planting
Son；Hole tray be first put into nursery hole in balance after sow again；The seed of identical cross combination is broadcast in same hole tray and hangs up record
There is the label of cross combination；After sowing, make the water surface educating lower than 1~1.5cm of hole tray top surface using pouring water in nursery is cheated
Seedling cheats interior irrigation method watering, is then sprayed again with watering can on hole tray surface permeable；Plastic canopy is built in top in nursery is cheated, and moulds
Expect the sunshade net that shading rate 50% is covered on arched shed, temperature is at 20~28 DEG C in control plastic canopy；To neat after aforementioned watering
Miao Qian makes nursery of the water surface lower than 1~1.5cm of hole tray top surface cheat interior irrigation method watering holding cave by pouring water in nursery is cheated
Water content of substrate is same to be lower than the water surface using pouring water in nursery hole before 90% or more, Qi Miaohou to kind transplantation of seedlings in disk
Water content of substrate is 75%~85% in irrigation method watering holding hole tray in the nursery hole of 1~1.5cm of hole tray top surface, to seedling
Tape base replanting is to dig deep 10~15cm on ground in big Tanaka, the nursery hole when having 4~5 true leaves, and it is wide to be wider than hole tray
The rectangle hole of 3~5cm is spent, and one length direction of digging is consistent with nursery hole length direction by nursery hole and depth is greater than
The gutter of nursery hole depth.
Further, the matrix in the hole tray is formulated as follows: by soil, turf and perlite by soil: turf:
The volume ratio of perlite is that the ratio of 2:3:1 mixes mixed-matrix I, and every 1 cubic metre of mixed-matrix is pressed in mixed-matrix I
I 500 grams of 75% Bravo wettable powder of addition mixes to obtain the matrix thoroughly.
Further, the depth of sowing is 0.8~1.2cm.
Further, the hole tray is the deep 12~15cm in cave, 50 holes/disk hole tray.
Further, after planting the 15th day, the matrix in hole tray is irrigated once with mixed liquor I, the mixed liquor I is to use
The mixed aqueous solution or 50% of 50% 15 kilograms of 5~6 milliliters+water of 22 gram+40% of carbendazol wettable powder phoxim emulsifiable concentrate
22 gram+20% of carbendazol wettable powder goes out and sweeps sharp 15 kilograms of 3.8~4.3 milliliters+water of missible oil of mixed aqueous solution.
Further, Qi Miaohou sprays 1 22 gram+10% of 50% carbendazol wettable powder for every 10~15 days to before transplanting
The mixed aqueous solution of 15 kilograms of 4.3 milliliters+water of permethrin milk oil sprays 2 times altogether；Or spray 1 75,%00 bacterium in every 10~15 days
The mixed aqueous solution of clear 15 kilograms of 4.3 milliliters+water of 18 gram of+10% permethrin milk oil of wettable powder, sprays 2 times altogether.With prevention
The pest and disease damages such as samping off, root rot, thrips.
Further, it when grape seedlings have 3 true leaves, pours and applies microelement mixed fertilizer aqueous solution in a 0.1%w/w, it is described
Middle microelement mixed fertilizer aqueous solution is by 2 parts by weight of magnesium sulfate+1 parts by weight of ferrous sulfate+1 parts by weight of zinc sulfate+water, 4000 weight
Amount part is uniformly mixed, and grape seedlings is promoted to grow vigorously.
Further, further include that thinning is filled the gaps with seedlings: when grape seedlings have 2~3 true leaves, each hole retains 1 young plant in hole tray,
Extra seedling selection did not had in the hole of seedling and irrigates in the dusk or cloudy day, the matrix that fills for being transplanted to same combination
Water, watering keeps matrix wet in hereafter 3 days.
Further, the dried grape hybrid seed is Hybrid Grape seed of the water content less than 20%.
Further, the dried grape hybrid seed by mature and plump with plastic film environmental sealing is moulded with 3~5 layers
Expect film environmental sealing.
Compared with prior art, the method for the present invention has the advantages that
1, it by Hybrid Grape seed cryopreservation 4 months or more, promotes the sprouting of seed and improves emergence rate.Factually
It tests, in 1~7 DEG C of cryopreservation time less than 4 months, because athermobiosis is insufficient, percentage of seedgermination is generally below
50%, the germinations of top it all off some cross combinations and emerge irregular, the time of emergence draws longer, from emergence to
The combination of Qi Miaoyou needs 20~25 days (normal only to need 10~15 days), makes troubles to management.Hybrid Grape seed is with 3
~5 layers of plastic film environmental sealing make seed not contact wetting in cold storage procedure, seed drying are kept, in refrigerator or refrigerator-freezer
Interior refrigeration 4 months or more, cold storage environment cannot freeze in principle, that is, cannot be below 0 DEG C.In addition, dried grape of the invention is miscellaneous
Hand over seed cold preserving method different from widely used " sand storage " method in the north." sand storage " is in the wet sand for be embedded in seed 3~5 DEG C
Athermobiosis 2~3 months, seed must sow the seed in spring in next year, and (refrigerated storage temperature of " sand storage " method was actually in natural gas
Under time, temperature is difficult to control), and still have behind seed 2~3 years of dried grape hybrid seed cold preserving method preservation of the invention
80% or more germination rate, storage temperature can be with manual controls.
2, before sowing, after being impregnated seed 6~8 hours with 20~30 DEG C of 20mg/L~30mg/L gibberellic acid solution, than straight
Sowing (not impregnating the direct of seed using 20~30 DEG C of 20mg/L~30mg/L gibberellic acid solution to be sowed with seed) is connect, it can be with
It emerges 7~10 days ahead of time.
3, the method for the present invention is that hole tray is placed in nursery hole by hole plate seedling growth method in nursery is cheated, and is poured water in nursery hole
Nursery of the water surface lower than 1~1.5cm of hole tray top surface is set to cheat interior irrigation method watering.The moisture of Hybrid Grape seed seedling-raising in seedling stage
Management be it is very crucial, after planting to Qi Miaoqian matrix must be always maintained at higher humidity (water content of substrate 90% with
On), especially emergence to neat seedling stage, once moisture content deficiency emergence rate will significantly reduce.Before Qi Miaozhi is out of the garden, the humidity of matrix
Then can appropriate lower (water content of substrate 75%-85%), while also to pour and apply 2~3 fungicide and insecticide, to subtract
Light samping off, root rot and the generation of thrips and cause harm, it is ensured that have higher planting percent.
The Hybrid Grape seed seedling-raising stage, temperature was higher, and water management is particularly important.The prior art in heliogreenhouse or
Hole plate seedling growth on seedling culture frame in greenhouse, moistening effect is poor, must water daily 1~2 time, waters time-consuming, slightly dredges
Suddenly cause cannot to emerge, wither it is here dead.And the present invention places hole plate seedling growth in nursery is cheated, awning film is built in top, additional
Sunshade net, pouring water in nursery hole makes nursery of the water surface lower than 1~1.5cm of hole tray top surface cheat interior irrigation method watering, water-retaining property
Good, irrigation times largely reduce, fill within 3~7 days when temperature is low a water (if in hole tray surface lid thin film again, Water-saving effect
More preferably), the water of filling in 2~4 days when temperature is high, and dug a deeper gutter by nursery hole, avoid ponding and
Lead to rotten and grape seedlings death, save process, saves recruitment cost.
4, the present invention had not only been saved matrix but also had been ensured the water conservation of hole tray using the deep 12~15cm in cave, 50 holes/disk hole tray
Property, each cave of the few hole tray of cavities number then waste matrix greatly very much, the too small then poor water retention property in each cave of hole tray more than cavities number.
5, it begins sowing in good time and strengthens management.Early spring, when temperature can be sowed up to 15.0 DEG C or more.Substrate seedling it is general
In beginning rudiment in after planting 30~40 days, athermobiosis abundance and sowing time matrix moisture content were sufficient, needed from emergence to neat seedling
10~15 days.But the speed of emergence mainly with whether abundant athermobiosis, sowing time temperature, moisture content etc. are closely related.Emergence rate,
Planting percent height is also horizontal with seed plumpness, the sowing depth, seedbed management, and (control of moisture content and temperature, is applied pest and disease damage prevention and control
Fertilizer) etc. it is closely related, as pesticide and concentration of fertilizer it is bigger than normal can burn seedlings and reduce planting percent, arid and high temperature (35 DEG C or more) to go out
Seedling rate and planting percent have significant impact.So seed is full, athermobiosis is sufficient, it is certain density red to use before sowing
Mould acidleach kind, depth of planting is moderate (1.0cm or so), and after planting water, fertilizer, air and heat are coordinated, and the prevention and control of plant diseases, pest control in place, and does not have
Phytotoxicity occurs, fertilizer damage and arid, ponding causes harm and high temperature burn seedlings, emergence rate and planting percent are high.Emergence rate and planting percent
Height is influenced by Multiple factors, can be determined not depending merely on certain method for culturing seedlings.
The present invention, seed is antistaling storing 4 months or more in refrigerator or refrigerator-freezer, the abundant mature and plump of seed and low temperature is stopped
Sleep sufficient, liquid manure gas heat is mutually coordinated in nursery hole disk seedling raising process, and emergence rate reaches 80% or more, planting percent 90% with
On.
