Description

Clonal cultivar method for culturing seedlings
Technical field
The present invention relates to a kind of tea tree method for culturing seedlings, in particular it relates to a kind of clonal cultivar method for culturing seedlings.
Background technology
Cuttage is also referred to as cutting, be it is a kind of cultivate plant conventional asexual reproduction method, by the stem of clip plant, leaf, root, In bud, or insertion soil, Sha Zhong, or be soaked in water, just can be planted after taking root, make independent plant.Tea tree is Perennial industrial crops, its propagation method is divided into two kinds of generative propagation and vegetative propagation.Generative propagation, is by tea tree seed sowing To be bred.Because there is significant advantage in clone tea place in production, single node cutting turns into the main breeding side of tea shoot Formula.
At present, domestic that intensive cuttage is generally carried out in Small plastic shed using a leaf short fringe one cun long, spacing in the rows is 1~3 Cm, this method for culturing seedlings cost is low, and technology is simple, and still, Small plastic shed structural stability is poor, to the resistivity of natural calamity It is poor, run into sleety weather and easily occur cave-in accident, nursery risk is higher;Meanwhile, carried out using a leaf short fringe one cun long Cuttage, survival rate is relatively low, and growing-seedling period is up to 1 year, less efficient.
The content of the invention
In view of this, the present invention provides a kind of clonal cultivar method for culturing seedlings, to solve the above problems.
Specifically, the present invention is adopted the following technical scheme that:
A kind of clonal cultivar method for culturing seedlings, it comprises the following steps:
Cuttings takes the cm of 2~3 leaf 5~7 short fringe to insert and carries out no earth culture in seedlings nursing plate and educate, and insertion depth is 4~5 cm, row strain Away from for 12~15 cm;
It is 28~38 DEG C that seedling, which is cultivated, in temperature, and relative humidity is more than or equal under conditions of 70%, cultivates the short fringe until long The seedling of the leaves of Cheng Yiya 2~3, and >=10 cm and lengthwise >=15cm that grow crosswise of the fibrous root of the seedling;
Hardening by the seedling move into containing become thoroughly decomposed Nutrition Soil nutritive cube in and sterilized, hardening treatment, obtain transplanting Tea shoot, the root system for transplanting tea shoot is around the admittedly described Nutrition Soil that becomes thoroughly decomposed.
Also include based on above-mentioned, the step of the cuttings:Healthy and strong fringe bar raw then is taken from maternal plant garden, by the fringe bar Fringe under leaf segment defoliation, stay 2~3 leaves, 5~7 cm leaf segments to obtain the short fringe.
The step of based on cuttings described above, includes:The seedlings nursing plate is placed in the first greenhouse, and in the seedlings nursing plate The particle diameter for the pearl sand being equipped with the pearl layer of sand that thickness is 10~15 cm, the pearl layer of sand is 0.1~0.3 mm;By institute State short fringe and insert and carry out no earth culture in the pearl layer of sand and educate.
Include based on above-mentioned, the step of the cultivation seedling:First spraying concentration is molten for 50~200 mg/kg root-inducing powder Liquid, then in temperature be 30~35 DEG C, relative humidity is more than or equal under conditions of 70%, will the short fringe cultivation 7 days, damp condition Constant, temperature starts sprinkling foliar fertilizer solution, pressed under the conditions of 30~38 DEG C, to continue to cultivate to 1~1.5 complete leaf is sprouted The foliar fertilizer solution is persistently sprayed according to 7~10 days/time of frequencies to cultivate 43~58 days, obtains the seedling.
Based on above-mentioned, the aqueous solution of the rooting powder solution ABT root-inducing powders.
Based on above-mentioned, the foliar fertilizer solution include 0.3%~0.5% potassium dihydrogen phosphate, 0.3%~0.5% urea and 30%~50% foliar fertilizer.
Based on above-mentioned, the foliar fertilizer includes the component of following mass fraction:0.5%~0.8% nitrogen, 0.3%~ 0.5% potassium oxide, 0.3%~0.5% magnesia, 0.2%~0.3% Zn-ef ficiency, 0.1%~0.2% boron element, 0.2%~ 0.3% ferro element and 0.1%~0.2% manganese element.
Include based on above-mentioned, the step of the hardening:The seedling is moved into the nutritive cube being placed in the second greenhouse In, the sterilization of thiophanate-methyl solution is sprayed, starts hardening at 35~37 DEG C, 15~20 DEG C is progressively cooled to during hardening, Hardening 15~23 days, obtains the transplanting tea shoot.
Based on above-mentioned, the Nutrition Soil that becomes thoroughly decomposed is pulverized and mixed after sterilization treatment for yellowish-brown loam, useless Bag Material bacterium rod, then added Composite fertilizer, bactericide and auxin, which are mixed, stacks the Nutrition Soil that curing is obtained.
Compared with prior art, the present invention is with prominent substantive distinguishing features and significantly progressive.The present invention provides a kind of Clonal cultivar method for culturing seedlings, this method, which is first passed through, to be inserted short fringe in seedlings nursing plate and educated without earth culture, obtains seedling;Then again By the seedling, hardening obtains that the tea shoot of garden transplanting can be gone out in the Nutrition Soil that becomes thoroughly decomposed, and whole growing-seedling period was foreshortened in 3 months, Greatly improve breeding efficiency;Wherein, cuttings process selects the cm of 2~3 leaf 5~7 healthy and strong short fringe, greatly simplify institute The cultivating process of seedling is stated, is also beneficial to improve survival rate;And cuttings distance between rows and hills is provided more for 12~15 cm for seedling growth Big growing space, is conducive to growing up strong and sturdy for seedling;The hardening stage is using the Nutrition Soil that becomes thoroughly decomposed simultaneously so that the root system of tea shoot will The Nutrition Soil that becomes thoroughly decomposed is fixed, and the nutritious soil of tea shoot tether panel is conducive to tea shoot preservation for a long time during tea shoot is transplanted, it is to avoid Because root system for a long time it is exposed outside and caused by root system damage cause tea shoot be not easy to survive;Simultaneously so that go out the tea shoot of garden transplanting Root system carries substantial amounts of Nutrition Soil and also causes tea shoot higher to transplanting the adaptability on ground after transplanting, it is easier to transplant successfully;Finally, The seedlings nursing plate and the nutritive cube can be placed in the vinyl house of stabilized structure by whole seedling raising process, it is to avoid intense environment becomes Change causes nursery risk;The seedlings nursing plate and the nutritive cube, which are placed in different greenhouses, simultaneously carries out nursery, can effectively carry High breeding efficiency.
