Abstract
The invention discloses a method on seedling breeding of purple sweet potato, comprising the steps of 1, disinfection of seed potato: choosing big potato pieces which have no scars and scabs as the seeds; 2, seedbed arrangement, choosing sandy soil as compost which is from high and dry terrain, and with good permeability and rich organic matter, then fertilizing the seedbed with mature pig manure for 500-600 kg; 3, planting seed potato in rows: when it is at a stable temperature of 15 oC, planting the seed potato on seedbed orderly in rows; and 4, seedbed management: before seedling emergency, controlling the temperature of seedbed between 25-33oC and 20-25 oC after emergency, fertilizing the seedbed with thin human wastes in time for topdressing; earthing up the seedlings when 80% of the heightgrow to a height of 10 cm, and conduct earth up every two weeks after that. The seedling breeding method can effectively avoid the emergency of diseases like black spot disease, with high-survival seedlings, providing the foundation for high productivity of purple sweet potato.
Description
Technical field
The present invention relates to a kind of purple sweet potato method for culturing seedlings, it is applied to purple sweet potato planting technology field.
Background technology
Purple sweet potato is dark red potato again, and potato meat in addition to having the nutritional labeling of common Radix Ipomoeae, goes back richness in purple to darkviolet
Containing selenium element and anthocyanidin, all extremely sell well with international market at home, development prospect very well, has good cultivating value；
Start to plant purple sweet potato in the market a part of Planting household also occurring, but many Planting households are carrying out nursery to purple sweet potato
When, continue to using the seedling raising mannerses cultivating common Radix Ipomoeae, purple sweet potato seedling is produced certain affect, remote-effects are purplish red
The yield of potato, brings certain economic loss.
Content of the invention
Above-mentioned for solving the problems, such as, the invention discloses a kind of purple sweet potato method for culturing seedlings, seedling can be made to survive soon, for purple
Radix Ipomoeae high yield provides basis.
The invention discloses a kind of purple sweet potato method for culturing seedlings, specifically comprise the following steps that
(1) potato seed sterilization: select the no big potato wedges of scar, disease-free spot, block as potato seed, select the 600 times of liquid conducts of 25% carbendazim
Bactericidal liquid, bactericidal liquid is heated to 50 ~ 55 DEG C, then potato seed is placed on immersion 5 ~ 10min in bactericidal liquid；
(2) seedbed arranges: selection physical features is high and dry, soil permeability is good, the sandy soil rich in organic matter is as compost, seedbed width
Build as 1 ~ 1.5m, highly for 0.2 ~ 0.3cm, length is depending on field, and mu applies the pig manure 500 ~ 600kg becoming thoroughly decomposed；
(3) discharge potato seed: when temperature is stablized at 15 DEG C, potato seed is neatly emitted on seedbed, the matting that then every mu of use is become thoroughly decomposed
Fertile 400 ~ 500kg, barnyard manure is uniformly covered the fine earth being covered with 1 ~ 2cm in potato seed on barnyard manure upper strata, finally overall covering ground
Mulch film surrounding is simultaneously compacted by film；
(4) seedbed management: before emerging control nursery bed temperature between 25 ~ 33 DEG C, after emerging temperature control at 20 ~ 25 DEG C, temperature
Timely ventilation and heat when high, when night temperatures are low, can cover Rhizoma Imperatae and heat up；Simultaneously in potato seed germination period and height of seedling in 12 ~ 15cm
When, apply thin night soil to seedbed in time, topdressed；When there being 80% height of seedling 10cm, manually earth up once, afterwards every one
Individual week earths up once again.
Using the technical program, the invention has the beneficial effects as follows: before carrying out seedbed nursery, sterilized first, can
It is prevented effectively from the generation of the diseases such as purple sweet potato melasma, in seedling raising process, topdresses in time and earth up, make the seedling cultivating
Survive fast, provide basis for later stage purple sweet potato high yield.
Specific embodiment
The invention discloses a kind of purple sweet potato method for culturing seedlings, specifically comprise the following steps that
(1) potato seed sterilization: select the no big potato wedges of scar, disease-free spot, block as potato seed, select the 600 times of liquid conducts of 25% carbendazim
Bactericidal liquid, bactericidal liquid is heated to 50 ~ 55 DEG C, then potato seed is placed on immersion 5 ~ 10min in bactericidal liquid；
(2) seedbed arranges: selection physical features is high and dry, soil permeability is good, the sandy soil rich in organic matter is as compost, seedbed width
Build as 1 ~ 1.5m, highly for 0.2 ~ 0.3cm, length is depending on field, and mu applies the pig manure 500 ~ 600kg becoming thoroughly decomposed；
(3) discharge potato seed: when temperature is stablized at 15 DEG C, potato seed is neatly emitted on seedbed, the matting that then every mu of use is become thoroughly decomposed
Fertile 400 ~ 500kg, barnyard manure is uniformly covered the fine earth being covered with 1 ~ 2cm in potato seed on barnyard manure upper strata, finally overall covering ground
Mulch film surrounding is simultaneously compacted by film；
(4) seedbed management: before emerging control nursery bed temperature between 25 ~ 33 DEG C, after emerging temperature control at 20 ~ 25 DEG C, temperature
Timely ventilation and heat when high, when night temperatures are low, can cover Rhizoma Imperatae and heat up；Simultaneously in potato seed germination period and height of seedling in 12 ~ 15cm
When, apply thin night soil to seedbed in time, topdressed；When there being 80% height of seedling 10cm, manually earth up once, afterwards every one
Individual week earths up once again.
Finally it is noted that above example only not limits technology described in the invention in order to the present invention to be described
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still the present invention can be modified or equivalent；And all are without departing from this
The technical scheme of spirit and scope of invention and its improvement, it all should be covered in scope of the presently claimed invention.
