Description
Technical field
The present invention relates to the breeding methods that a kind of cold resistance irrigates tangerine seedling.
Background technology
Fertile mandarin orange belongs to one kind of citrus；" 1. fertile mandarin orange " cold resistance is medium, the citrus producing region of suitable 17.5 DEG C of year samming or more
Plantation, it is desirable that winter minimum temperature is not less than 0 DEG C.2. fragrant citrus, red tangerine, trifoliate orange, citrange can be selected in production does stock, deposited with trifoliate orange shaddock
In incompatibility, selection trifoliate orange shaddock is avoided to do stock.In the high area of heat, avoid walka is selected to write from memory, thick lemon etc. it is strong
Gesture stock, in case fruit acidity is too low and makes flavor thin out." 3. fertile mandarin orange " growing way is strong, the fruit extension tree time is long, to the need of rich water
The amount of asking is larger, heavy dressing base manure is answered in production, base manure is based on the farm manure of putrid fermentation and composite fertilizer.On purple soil, barren slope
Plantation should strengthen the improvement to soil, more organic fertilizers and phosphorus potash fertilizer on the ground, supplement zinc, fertiliser containing magnesium in right amount, ensure that blade leaf color is dense
It is green.4. " fertile mandarin orange " yielding ability is stronger, Fruit In Winter shedding is few, hangs tree function admirable, the fruit fruit picking phase is long, to avoid fruit less than normal
And biennial fruiting, fruit thinning and in due course fruit picking should be paid attention in production according to tree body load.
Fertile mandarin orange of the prior art is the location for being planted in warm drying mostly, therefore the area partially cold in the north is uncomfortable
It preferably plants, northerner needs to transport from other places, cause the rise of fertile mandarin orange price when needing edible fertile mandarin orange.
Invention content
The technical problem to be solved in the present invention is to provide the breeding methods that a kind of cold resistance irrigates tangerine seedling, pass through this method institute
Cultivate fertile mandarin orange plant have stronger adaptability, can under -1 DEG C or more of temperature condition preferably survival and as a result,
The plantation limitation of fertile mandarin orange is reduced, increases the planting area of fertile mandarin orange so that fertile mandarin orange becomes a kind of affordable, and nutritive value is higher
Fruit, while cultivated by this method, the death rate of fertile mandarin orange seedling can be reduced, improves the survival rate of fertile mandarin orange seedling, together
When cultivated by this method, the limb of fertile mandarin orange seedling obtained is more sturdy, grows fine.
To solve the above problems, the present invention adopts the following technical scheme that：
A kind of cold resistance irrigates the breeding method of tangerine seedling, includes the following steps：
1）The selection of seed：Choose the fertile mandarin orange fruit of low temperature planting area, the plantation temperature of low temperature planting area for -1 DEG C ~
17 DEG C, seed is taken out after fruit is broken, seed is screened after taking out seed, the seed of full grains is chosen, has chosen
Seed is rinsed with clear water after, washing time 10-15min；
2）The processing of seed：Seed is put into the liquor potassic permanganate of 0.3%-0.5% concentration and is impregnated, soaking time
8-10 hours, seed is taken out after the completion of impregnating, clear water is reused and is impregnated, soaking time 10-15min is thrown after the completion of impregnating
It puts to container, the gibberellin water for then adding in 0.065% concentration is impregnated, soaking time 2-3 days, is used after the completion of impregnating
Hydrogen peroxide is rinsed, washing time 15-25min, and sowing is waited for after the completion of rinsing；
3）The implantation of seed：Prepare the cultivation slot of a frame shape, stone is put in the bottom for cultivating slot, on the surface of stone
Wet sand is laid with, thin mud is laid on the surface of wet sand, the laying depth of stone is 10cm-15cm, and a water storage is formed between stone
Gap, the laying depth of wet sand are 5cm-7cm, and the laying depth of thin mud is 15cm-20cm, by seed be inserted into thin mud and wet sand it
Between, preservative film is laid on the surface of thin mud after the completion of seed insertion, the surface of preservative film opens up through-hole, and through-hole is opposite with seed；
4）Nutriment supplies：By fertile soil：Chicken manure：Cow dung：Urea：Composite fertilizer=3：1：2：1：2 ratio is mixed, and is obtained
To nutriment, nutriment is thrown to the upper of thin mud by through-hole, the time interval that nutriment applies is 4-6 days；
5）Cultivating seedlings：After germination in transplanting to greenhouse, the humid control inside greenhouse is empty at 10 DEG C -17 DEG C
Air humidity degree 20%-45%, is when the temperature is excessively high aerated greenhouse processing, is increased by spraying moisture when air humidity is too low
Air humidity passes through ventilation process reduction air humidity, 3-5 months cultivating seedlings time, cultivating process when air humidity is excessively high
In to spray diluted concentration weekly be 400-650 times of carbendazim aqueous solution, to prevent the generation of damping-off and anthracnose, work as nursery stock
When growing height is 20-30cm, gap is opened up around nursery stock, the depth in gap is 10-18cm, is added in gap compound
Fertilizer and urea, every plant of compound fertilizer amount of addition are 50-100 grams, and every plant of addition urea amount is 50-80 grams, and composite fertilizer and urea add
It is 15-18 days/time to add the period；
6）Nursery stock transplanting：When seedling growth is to 40-60cm, transplanted, using soil ball cladding nursery stock root during transplanting,
Then apply moisture in soil ball so that the water retention of soil ball is controlled between 8%-16%.
7）Maintenance after transplanting：Hole is opened up on the soil transplanted, soil ball is placed directly within to the inside of hole, then
Soil is covered, is laid with thermal insulation material after the completion of covering in the root of nursery stock, the laying depth of thermal insulation material is 10cm-15cm, and
Afterwards weekly to a nutriment, nutriment is composite fertilizer and the mixture of urea, and the mixing ratio of composite fertilizer and urea is 2：1, single seedling
The nutriment supply amount of wooden plant is controlled in 100-250g；
8）Trimming：When band seedling growth is to 1.5m-1.8m high, extra limb is trimmed, ensures the length that major branch is done
Gesture；
9）It cultivates and completes.
Preferably, the thermal insulation material is stalk clast or straw clast.
The beneficial effects of the invention are as follows：The fertile mandarin orange plant cultivated by this method has stronger adaptability, can be with
It is preferably survived under -1 DEG C or more of temperature condition with as a result, reducing the plantation limitation of fertile mandarin orange, the planting area of mandarin orange is irrigated in increase,
So that fertile mandarin orange becomes a kind of affordable, the higher fruit of nutritive value, while cultivated by this method, can reduce fertile
The death rate of mandarin orange seedling, improves the survival rate of fertile mandarin orange seedling, while is cultivated by this method, the fertile mandarin orange seedling obtained
Limb is more sturdy, grows fine, and is suitble to promote the use of.
