Description
Technical field
The present invention relates to a kind of sweet potato seedling-raising technique field, more particularly to a kind of segmented nursery side of Sweetpotato Viruses Elimination seedling
Method.
Background technology
Sweet potato is the main cereal crops in China, and nursery is the primary link in its production, and obtains Sweet Potato For High. yield Production
Basis, therefore, the quality of sweet potato Quality of Seedlings directly affect the yield of sweet potato, and strong sprout early growth and quick tiller, knot potato is early and more, plants in good time
Kind, yampi rate is high while saving potato seed, has obvious effect of increasing production, however, traditional sweet potato seedling raising mannerses are all different degrees of
Ground there is easy rotten bed, reproduction speed is low, production cost is high, easily infected virus the problems such as.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of segmented method for culturing seedlings of Sweetpotato Viruses Elimination seedling is provided.
The present invention to achieve the above object, using following technical scheme：A kind of segmented method for culturing seedlings of Sweetpotato Viruses Elimination seedling,
It is characterised in that it includes following steps：
(1) virus-free seed potato is screened, the potato seed color of the leather of selection wants smooth vivid, and potato wedge size is neat, uniformity, appearance
Unabroken potato seed；
(2) preparation of germination bed, the heating wire laying area from 1000W is 6m2, then the uniform fold on heating wire
8cm thickness stalks, forbid heating wire exposed and intersect, and external temperature controller, power backup；
(3) processing of virus-free seed potato, by the methyl Tobe that the virus-free seed potato mass fraction of screening in step (1) is 30%
Tianjin dilutes 200 times of liquid seed soaking 12-16min, connects the power supply of germination bed, makes the temperature stabilization of germination bed at 30 DEG C, after processing
Virus-free seed potato be fitly stacked on germination bed, the stacking of virus-free seed potato is highly 40-60cm, and surrounding is covered with insulation material
Lid, keeping vernalization bed tempertaure, humid control is between 70-75% in the range of 35-38 DEG C, after 1-2 days virus-free seed potato snuffs, uses
Warm water drenches potato layer, after vernalization bed tempertaure is maintained at into 28-30 DEG C, 8-10 days when 90% virus-free seed potato bud long 1cm, by vernalization
Bed tempertaure prepares to divide bed to arrange potato after being down to 20-24 DEG C, 11-13 days；
(4) to divide bed to arrange potato, potato, upper flat lower injustice are arranged using flat raft mode, water penetration seedbed is used on the row of sprouting side after sequencing,
Covered with Nutrition Soil, thickness 3cm, keep seedbed gentle；
(5) seedbed management, during height of seedling 4cm, when to control temperature be 25-30 DEG C, humidity 65-75%, height of seedling 15-20cm,
Temperature is down to 20 DEG C, after 2-3 days, you can cutting seedlings；
(6) cutting seedlings, when potato seedling growth grows to 25-30cm, timely cutting seedlings is answered, high cutting seedlings of collecting seedling, that is, cuts off top 10-15cm, stay
High seedling, i.e. base portion stay 6-9cm not cut, and instant nitrogenousfertilizer is sprayed after collecting seedling, and new talent is sprouted after 3-4 days, that is, complete segmented nursery.
Particularly, it is 40% that the thiophanate methyl that mass fraction is 30% in the step (3), which replaces with mass fraction,
Carbendazim.
Particularly, instant nitrogenousfertilizer refers to 0.3% urea and 0.5% potassium dihydrogen phosphate mixed liquor in the step (6).
The beneficial effects of the invention are as follows：Sweetpotato Viruses Elimination seedling of the present invention uses segmented nursery, passes through heating wire temperature control instrument control
The temperature of germination bed processed so that temperature-controllable, rotten bed rate is greatly reduced, while improve the reproduction speed of Sweetpotato Viruses Elimination seedling,
And then production cost has been saved, before virus-free seed potato snuff, germination bed temperature control effectively prevent infection in 35-38 DEG C of scope
The problem of viral.
