The present invention provides a kind of method of sweet potato single-unit seedling, passes through the selection of sweet potato single-unit: selection section is full, and axillary bud is not damaged, the single-unit clip of strong and vigorous growth, and single-unit length upper and lower side is no more than 2cm；Single-unit disinfection: single-unit 30min is impregnated using the Zhongshengmycin mixed plant hormone of the difenoconazole containing 0.1 ~ 0.3 g/L, 0.01 ~ 0.1 g/L；It manually urges root: soaked sweet potato single-unit being put into vernalization in artificial incubator and urges root, 30 ± 1 DEG C of cultivation temperature, humidity 80 ± 5%, 10000 ~ 12000lx of intensity of illumination, 12 ~ 14h of light application time, vernalization can plant in culture substrate after urging root one day.Accelerate sweet potato potato seedling growth and breed speed, mention breeding coefficient, meets the needs of sweet potato production.
Description
Technical field
The present invention relates to a kind of arable farming methods, and in particular to a kind of sweet potato single-unit Raising plantlet belongs to plant culture
Technical field.
Background technique
Currently, the method for traditional sweet potato nursery is broadly divided into two kinds of potato wedge nursery and tendril nursery, potato wedge nursery has can be with
It is divided into plastic film covering seedbed nursery, covering with ground sheeting nursery, vinyl house open country nursery；Tendril nursery is divided into seedling temporary planting and educates
Seedling and the climing overwintering nursery of point etc., both plantleting modes are easy to be influenced by factors such as temperature, rainfall, illumination, once extremely
Weather occurs that the rate of sweet potato seedling will be substantially reduced, and influences to produce.In order to solve these problems, we have proposed sweet potato single-units
The method of seedling mentions breeding coefficient, meets the needs of sweet potato production to accelerate sweet potato potato seedling growth breeding speed.
Summary of the invention
The purpose of the present invention is to provide a kind of methods of sweet potato single-unit seedling.
To achieve the above object, the present invention adopts the following technical scheme:
(1) material selects: select high-quality strong sprout as single-unit material, variety is not less than 99.9%, potato seedling growth diameter 0.3 ~
0.6cm, no disease and pests harm, no yellow leaf；
(2) single-unit clip: selection section is full, and axillary bud is not damaged, and the single-unit clip of strong and vigorous growth, single-unit length upper and lower side is not
More than 2cm；
(3) single-unit sterilizes: after the single-unit sheared is cleaned with clear water, using the difenoconazole containing 0.1 ~ 0.3 g/L, 0.01
The aqueous solution soaking single-unit 30min of the Zhongshengmycin of ~ 0.1 g/L, plant hormone；
(4) it manually urges root: soaked sweet potato single-unit being put into vernalization in artificial incubator and urges root, it is 30 ± 1 DEG C of cultivation temperature, wet
Degree 80 ± 5%, 10000 ~ 12000 lx of intensity of illumination, 12 ~ 14 h of light application time, vernalization can plant after urging root one day in culture
In matrix；
(5) single-unit is planted: by the plantation of sweet potato single-unit in clean vermiculite matrix, with ripe 3 ~ 5 kg of chicken manure of every square meter, compound fertilizer
For 0.3 ~ 0.5 kg as base manure, plantation spacing is 10 ~ 15cm, and planting density is 100 ~ 120 single-units/m2, a list is put in every cave
Section, is watered with water, is covered with new vermiculite；
(6) liquid manure and pest management: the sowing same day and after planting 15 days, 30 days are respectively watered with a water, and vermiculite is wet, holds
Vermiculite without water droplet to just oozing；After planting 15 days, 30 days, it is primary that cooperation increases top dressing, and water soluble composite fertilizer uses
Amount is 0.5kg/m2, the conventional prevention and control of plant diseases, pest control in growth period.
The plant hormone is one of NAA, 6-BA or NAA and 6-BA mixture of 100 ~ 400ppm.
The present invention has the advantages that
1, reproduction speed is very fast, and breeding coefficient is high, has regulated and controled the factors such as water, fertilizer, light, temperature, humidity, can meet single-unit potato seedling growth
The reproductive efficiency of original potato seedling growth can be greatly improved in fast-growth, single-unit seedling；
2, it is strong to keep away disaster ability, increases economic efficiency, either potato wedge nursery or tendril nursery is highly prone to low side nature
The influence of weather is influenced sweet potato normally for seedling, calamity ability of keeping away can be improved using single-unit Raising plantlet, guarantees that sweet potato plants period
For seedling, increase for seedling quantity, guarantee that the economy of peasant household is not suffered a loss.
3, technically simple, practical, general agricultural base technical staff can complete this seedling raising process.
