Abstract
The invention provides a potato seed storage method, which comprises the following steps: selecting potato seeds with uniform size; using 1 to 16 mg/l of uniconazole to soak the potato seeds for 15 to 30 min; and storing the potato seeds under the condition of 18 to 20 DEG C after the moisture is dried. The method prolongs the storage period of the potatoes, and can also regulate and control the storage period of the potatoes so that the dormancy can be fast broken when the potatoes needs to sprout, and strong and healthy seedlings are sprouted. The method has simple operation, and is suitable for wide popularization and application.
Description
Technical field
The present invention relates to the storage field of seed potato, particularly a kind of seed potato storage practice, this method is handled seed potato with uniconazole P.
Background technology
The medicament that uses in the storage of potato is mainly at present: chlorpropham and naphthalene methyl acetate etc., these reagent all have good inhibition effect to the sprouting of potato bud.Naphthalene methyl acetate and chlorpropham mainly are by destroying the synthetic of potato sleeping bud apical meristem gibberellin, thereby reach the purpose that suppresses rudiment.Its embodiment is:
1, naphthalene methyl acetate: potato is when storage, and potato piece per ton with the fine earth mixing of naphthalene methyl acetate 40～50 grams with 2～3 kilograms, is evenly puddled fine earth in the potato piece earlier again.
2, chlorpropham: heap side is a several layers during storage of potato, and potato piece per ton is got 1.4 kilograms of chlorprophams, evenly applies or with blowing device it is blown into potato heap.
Yet these medicaments can only be applicable to the storage of eating potato raw, and make the storage that is applicable to seed potato.Because, if the storage that these medicaments are used for potato seed can cause germination rate low or can not normal growth, even if use external source gibberellin breaking dormancy and vernalization can not obtain effect preferably.Therefore, demand seeking new seed potato storage practice urgently,, when the needs rudiment, can abolish dormancy fast and can obtain healthy and strong seedling with the storage period of regulation and control seed potato.
Summary of the invention
Shortcoming at above-mentioned common agents, the invention provides a kind of seed potato storage practice, the uniconazole P of nonhazardous is used for the storage of seed potato, not only prolong the storage of potato phase, also can regulate and control its storage period, make it when the needs rudiment, can abolish dormancy fast, and sprout healthy and strong seedling.
Technical scheme of the present invention is: a kind of seed potato storage practice, choose seed potato of uniform size, soak 15～30min with 1～16mg/l uniconazole P, treat that moisture dries after, place under 18～20 ℃ of conditions and preserve.
The concentration of used uniconazole P of soaking seed is 4～16mg/l.
The concentration of used uniconazole P of soaking seed is 8mg/l.
Soak time is 20min.
10～30min breaks its dormancy in advance with the seed soaking of 5mg/l Gibberellins solution.
Uniconazole P is prolonging the purposes of seed potato in storage period.
The present invention forms antagonism with the storage period of uniconazole P prolongation seed potato, the gibberellin in uniconazole P and the potato and other rudiment factors, thus the sprouting of inhibition of potato young shoot.
The invention has the beneficial effects as follows: seed potato storage practice of the present invention, not only prolong the storage of potato phase, also can regulate and control its storage period, make it when the needs rudiment, can abolish dormancy fast, and sprout healthy and strong seedling.This method is simple to operate, is suitable for wide popularization and application.
Embodiment
Essence for a better understanding of the present invention illustrates seed potato storage practice of the present invention below in conjunction with concrete experiment and result.
Experiment material: No. 2, middle potato, Favorita, rice draws,
The uniconazole P solution of following concentration: 0mg/l, 1mg/l, 2mg/l, 4mg/l, 8mg/l, 16mg/l
Chlorpropham (CIPC)
Experiment: the influence that the uniconazole P of variable concentrations germinates to potato primary stock
1, preparation potato primary stock: choose the basic different cultivars potato primary stock uniformly of size, No. 2, promptly middle potato, Favorita and Mi La; The potato primary stock potato seed weight of these three kinds is 3～4g/ grain;
2, the uniconazole P seed soaking is handled: the potato primary stock potato seed of each kind is respectively got 5 parts, and 100 every part, gross weight is 340g, is respectively the uniconazole P seed soaking processing 20min of 1mg/l, 2mg/l, 4mg/l, 8mg/l, 16mg/l with concentration; Each is handled and repeats 3 parts; In addition, the potato primary stock potato seed of each kind is respectively got 2 parts, and 100 every part, gross weight is 340g; 1 part according to 1.4kg chlorpropham/1000kg potato, evenly applies chlorpropham respectively and handles; Handle 20min with the clear water seed soaking respectively for 1 part in addition, in contrast;
3, storage: after potato disposes, dry in the mesh bag of packing into, storage is 3 months under 18～20 ℃ of conditions;
4, sprout situation, the situation of sprouting, bud ratio, bud of each part of routine observation potato is long and calculate after the seed potato callus between sowing early stage after 3 months, indexs such as the loss in weight situation of every part of potato, averaged, and be recorded in table 1, table 2 and the table 3.
Table 1: uniconazole P is to potato primary stock germinating time and bud ratio influence
By data analysis in the table 1 as can be known, after the uniconazole P processing, the potato primary stock germinating time of three kinds all increases and prolongs along with the concentration of uniconazole P, and its germination rate is also all along with the concentration of uniconazole P increases and reduces.Wherein, when uniconazole P concentration was 16mg/l, bud inhibition effect was best, and when concentration was 8mg/l, bud inhibition effect took second place.
Table 2: uniconazole P is to potato primary stock terminal bud length variations and the influence of mashed potato rate
* long variation of terminal bud is meant the poor of germination period and the terminal bud length between sowing time
By data analysis in the table 2 as can be known, after the uniconazole P processing, the variation of the potato primary stock terminal bud length of three kinds all increases and reduces along with the concentration of uniconazole P, yet mashed potato rate but all increases along with the increase of uniconazole P concentration.Wherein, when uniconazole P concentration was 16mg/l, mashed potato rate was the highest, and when concentration was 8mg/l, mashed potato rate was taken second place.
Table 3: uniconazole P influences the potato primary stock loss in weight
In the analytical table 3 data as can be known, after handling with uniconazole P, the potato primary stock loss in weight of three kinds all reduces along with the increase of uniconazole P concentration, wherein, when uniconazole P concentration was 8mg/l and 16mg/l, the difference of the loss in weight was not remarkable.
Table 4: the potato growing way situation after planting after the uniconazole P of variable concentrations is handled
Annotate: height of seedling is the growth seedling height in most productive period (squaring period)
In the analytical table 4 data as can be known, after handling with uniconazole P, with the growth of concentration for the potato set of 16mg/l uniconazole P after handling, its growing way is not as with concentration after for the processing of 8mg/l uniconazole P.
Comprehensive The above results as can be known, when uniconazole P concentration is 16mg/l, bud inhibition effect to potato primary stock is best, when itself and uniconazole P concentration are 8mg/l, not remarkable to the difference of the bud inhibition effect of potato primary stock, yet, be higher than far away with concentration after for the mashed potato rate of the potato primary stock of 16mg/l uniconazole P after handling with concentration for the processing of 8mg/l uniconazole P, in addition, from the growth of later stage potato set, its growing way also not as with concentration for after the 8mg/l uniconazole P processing.Therefore, the optium concentration with uniconazole P processing seed potato is 8mg/l.
