Description
Technical field
The present invention relates to a kind of breeding method of plant seedlings, specifically a kind of breeding method of sweet potato seedling.
Background technology
Some traditional seedling raising mannerses of market at present, traditional sweet potato seedling-raising technique are that the sweet potato of autumn harvest is passed through into storage
Hide, transplanted in spring and cultivate potato rattan, then potato rattan is cut into rattan segment cuttage and breeds into sweet potato seedling.This method takes a lot of work, be time-consuming,
Take potato seed, the storage technology in winter is not easy to grasp, and influences next year breeding, therefore the planting patterns of this quasi-tradition is present too much not
Just and defect, the sweet potato in implantation methods of the invention ensures that sweet potato seedling can be constantly numerous by circulating the method for fertilising
Grow, bear stem tuber, be easy to people to circulate edible, the wasting of resources in field will not be caused, while plant sweet potato matter out
Amount is high, and nutrition is more abundant, while saves manpower and time.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of breed of crop field
Sweet potato seedling breeding method.
In order to solve the above technical problems, the invention provides following technical scheme：
A kind of breeding method of sweet potato seedling, is comprised the following steps that：
(1) cultivation of sweet potato's seedlings：Select some without insect pest first, without damaged, the sweet potato stem tuber without freeze injury, by stem tuber one
It is divided into two or larger stem tuber one dividing into three, is then ready for containing being crossed with a certain amount of peracetic acid disinfectant for quantitatively clear water
Glassware, then the stem tuber otch cut is overflow into clear water, stem tuber upper end is encorbelmented in clear water by being inserted with toothpick
Top, the place of direct sunlight then will be moved integrally, it is when going out seedling after waiting for a period of time, on stem tuber, seedling is complete
Portion is cut from bottom, will be cut seedling and is all put into water seedling is immersed in water, and clear water is regularly added into container for children
Seedling grows root system；
(2) selection of seedling：According to the root system of seedling growth situation, select root system intact, the seedling without disconnected palpus, remaining is damaged
The rotten seedling of wound, cultivation field is discarded in, is easy to increase the fertile degree of field soil, while avoid wasting；
(3) early-stage preparations of planting base：Select that loosing soil, soil property be deep, well-drained no sweet potato disease first
Hillside fields and sunny, deep plough, smooth and apply decomposed farm manure is then carried out to hillside fields, then just deep ploughs, play Gansu Province,
And it is auxiliary material that nitrogenous fertilizer wherein phosphorus and potassium are imposed between Gansu Province, and the acid-base value of appropriate regulation soil；
(4) transplanting of seedling：First every an intersegmental hole for having certain depth away from digging, then by seedling cultivation prior
In the hole dug, and last layer soil is covered, finally at the region of very cold, it is necessary to be carried out to seedling at epiphragma
Reason, the sweet potato seedling of the happiness heat because cold is freezed to death, and regular watering are avoided, in the region of hot climate, it is necessary to largely to children
Seedling, which is timed, pours water process, avoids sweet potato's seedlings from thirsting；
(5) field management and protection：Periodically fertilising is carried out to field soil to disinfect, and the adjustment to plant,
Can harvests some sweet potato stem tubers at regular intervals, is eaten, and timing subtracts branches and leaves, ensures the branch on every plant
Number of sheets amount is substantially constant, and then length is substantially inconvenient, carries out top dressing over time, ensures growth of sweet potato.
As the further improvement project of the present invention：The vierics in (1) the described sweet potato's seedlings breeding method the step of
Clear water amount in ware is that wherein the concentration of Peracetic acid should be used in cleaning-sterilizing glassware away from 4~8cm of port
0.2%~1% weak solution, insect pest is avoided to infect stem tuber otch, wherein stem tuber diffuses in water about 2/3 volume, and in sun
The time wait seedling that development time is 2~4 weeks is irradiated under light to grow, and when wherein seedling grows root system, is easy to overflow its root
In water inlet after 3/4 length, given every 24 hours in container and add clear water once, be easy to ensure its growth, after growing root system
Stop watering.
As further improvement project of the invention：Applied in (3) the described sweet potato's seedlings breeding method the step of
Farmers''s composting fertilizer be about 15~20t/h ㎡, deep Gansu Province is about 20cm, wherein Gansu Province spacing is 140cm~170cm, plays Gansu Province
Highly it is 30cm~35cm, wherein nitrogenous fertilizer is about 5~10t/h ㎡, wherein the acid-base value for controlling soil is neutral soil.
As further improvement project of the invention：The described sweet potato's seedlings breeding method the step of in (4) every
The depth that 30cm~60cm digs cave is that plant to stem tuber root, is then planted in hole and covered by 3cm on plant base portion
1.5cm soil, is easy to root to grow stem tuber in soil 15cm~30cm lower ends, and cold region is planting initial one month often
Its watering 1 time, degression type every month watering backward, until stem tuber is ripe, hot region is watered daily.
As further improvement project of the invention：In length in (5) the described sweet potato's seedlings breeding method the step of
When going out 5~6 tender leafs, it can search for food, wherein being trimmed every 1~2 week to branches and leaves, so as to ensure every plant of upper branches and leaves quantity
For 5~6, and every plant of branches and leaves length is grown no more than 5cm.
Compared with prior art, the beneficial effects of the invention are as follows：Nutrient sweet potato enriches, rich in starch, carbohydrate, protein,
Vitamin, cellulose and various amino acid, are extraordinary nutraceutical and sweet potato also has certain medical value, therefore
The plantation quality and plantation intensity effect of sweet potato the edible benefit brought of the people for sweet potato, are used in the present invention
The mode of Shi Xunhuan feeding sweet potatoes ensures that sweet potato can be with circular regeneration, and then top dressing uses repeatedly, and can be used for high yield,
The quality of sweet potato plantation is high, and disease insect pest is few, and can effectively control during seedling.
