Description
Technical field
The present invention relates to growing vegetables technical field, and in particular to germination accelerating method in a kind of seed potato room.
Background technology
Potato, belongs to Solanaceae herbaceos perennial, and stem tuber can be edible, is the fourth-largest important cereal crops in the whole world,
It is only second to wheat, paddy and corn.Potato is also known as potato, potato, foreign sweet potato etc., the stem tuber of plant of Solanaceae.With wheat, rice
Paddy, corn, sorghum simultaneously become five big crop of the world.
Potato has spring, two season of autumn plantation tradition in two Ji Zuo areas of the middle and lower reach of Yangtze River, due to 7-8 month high temperature, autumn Ma Ling
Potato generally by the end of August to September at the beginning of sowing, September emerges before and after 20 days, and early November harvest, temperature is too low after mid-November, ground
Top is easily dead, and therefore, potato breeding time in autumn is shorter, fits date of seeding only by the end of August to the September original treaty time of 10 days, suitable to broadcast
Phase is short.Under natural conditions, seed potato need to pass through the 2-3 neat sprouting stages of month rest period, about 1 month by harvesting to bud to sprout, because
Potato seed at least needs 3-4 months from harvesting to sowing under this natural conditions；On the other hand, again can be because of more than 3 months after neat bud
Germination excessively seriously affects yield.Therefore, the potato seed of spring production is because of overlong time after budding, it is difficult to the spring for next year
Broadcast, and the potato seed of autumn production did not had because of rest period, it is also difficult to sow in spring for next year.
Presprouting of seeds technology is applied in various plants, and effect is to break passive or physiological dormancy, is sowed ahead of time, is improved
Phase ofsprouting.To solve the above-mentioned problems, potato is imperative using Stratification technique.Common Stratification technique has gibberellin to urge
Bud method, sand bed stratification method, be shown in that light shines and dry in the air germination hastening method etc., but due to site requirements, budding controllability or seedling stage quality etc. because
Element, it is difficult to applied in extensive potato seed processing, though and gibberellin vernalization can effectively shorten germinating time, improve germination percentage,
But sprout is very thin, lateral bud number is few, harvest and the nutrient absorption of potato have been seriously affected.
The content of the invention
For above-mentioned problem, the present invention proposes germination accelerating method in a kind of seed potato room, by rational
Potato seed is handled, and the activity of potato seed has been effectively ensured, and bud ratio improves more than 35%, and germination time is short, and sprout is neatly healthy and strong,
Survival rate is up to 99%.
In order to realize above-mentioned purpose, the present invention uses following technical solution：
Germination accelerating method in a kind of seed potato room, step are as follows：
1) seed potato of harvest is subjected to cladding processing at room temperature, refrigerates and place under the conditions of being subsequently placed in 2-4 DEG C；
2) wait to sow first 10 days and take out seed potato, first soak 5-20min with 28-30 DEG C of warm water, remove clad,
After draining, then buried and be placed in compound windrow 5-7 days；
3) by step 2) warm water concentration after be freeze-dried powder is spare；
4) seed potato is taken out into stripping and slicing, ensures at least 1 healthy and strong bud eye on every piece, be then placed within damp sand
On, the mixture of powder in the damp sand and step 3) after one layer of 2cm of Surface mulch, continues vernalization and cultivates, keep temperature 18 ± 2
DEG C, treat that the long 2-3cm of bud can be sowed.
Preferably, cladding processing specifically, to seed potato surface sprinkling polyvinyl alcohol water solution, is spread in step 1)
After drying, then to seed potato top layer smear hydroxypropyl-β-cyclodextrin slurry, vacuum drying.
Preferably, the polyvinyl alcohol water solution mass content is 3-5%, and fountain height is 5-10ml/kg seed potatos.
Preferably, the hydroxypropyl-β-cyclodextrin slurry is by mass ratio 1：The hydroxypropyl-β-cyclodextrin of 1.5-3 and water
Mixture.
Preferably, step 2) is buried put during choose fair weather and shakeout and bask seeds 1-2 days, it is 20-26 DEG C to ensure temperature.
Preferably, step 2) is buried put during periodically spray 0.01-0.05wt% limewash, holding humidity is 60-80%.
Preferably, the mass ratio of damp sand and powder is 1 in step 4) mixture：0.3-0.5.
Due to using above-mentioned technical solution, the beneficial effects of the invention are as follows：The present invention is handled by rational potato seed, is had
Effect ensure that the activity of potato seed, and bud ratio improves more than 35%, and germination time is short, and sprout is neatly healthy and strong, plant survival rate
Up to more than 99%.
Seed potato is handled using cladding, on the one hand ensure that certain cytoactive degree, while is had good
Catalysis, the effect of guaranteeing the quality, the nutritional ingredient conservation degree of potato seed is high, and easy to breaking for rest period, energy is provided for later stage vernalization, comprehensive
It is good to close bud ratio, on the other hand, there is certain moisture absorption, isolation effect, improve the storage quality of potato seed, reduce go mouldy,
Inactivation rate.Soak and remove only with warm water compared to traditional vernalization, after present invention cladding, avoid making for chemical agent
With small on potato seed influence, sprout is more healthy healthy and strong, safe and efficient, environmentally protective.And the warm water containing coating layer material is by two
It is secondary to be used for sprout Surface mulch, there is excellent hygroscopicity and guaranteeing the quality property, ensure that the healthy growth of sprout.
