Abstract
A plant growth regulator for culturing the sapling by cuttage in wet-loose mode F2 is prepared from IBA (800 mg +/- 40 mg), NAA (400 mg +/- 20 mg), catechol (5.5 mg +/- 0.5 mg) and KT (0.02mg) through mixing and diluting with water. Its cuttage method is also disclosed.
Description
Technical field
The invention belongs to biological technical field, be specifically related to wet the grow seedlings plant growth regulator and use this plant growth regulator and carry out that F2 is wet to add the method that pine cuttage is grown seedlings of pine that adds of F2.
Background technology
F2 is wet add pine be by the offspring of Honduras pinus caribaea (Pinus caribaeavar.hondu-rensis) and wet-land pine tree (Pinus elliottii) this generation of father and mother each other hybridize again form two generation Hybrid, it combines this merit of father and mother, that is: fast, the internode distance of growth, contain grease height, few insect pest, suitablely give birth to characteristics such as scope is wide; Its early stage volume of timber gain is more than 3 times of parent, and hybrid vigour is very outstanding, is the fine tree species that are worthy to be popularized.But since at present cuttage and seedling culture exist good fringe bar source less, the cuttage root-taking rate is low, cutting time long, the cuttage cost is than problems such as height, is difficult to satisfy the growing market demand.
Summary of the invention
One object of the present invention is to provide F2 the wet pine cuttage plant growth regulator of growing seedlings that adds, and F2 is wet to add problems such as the pine cuttage rooting rate is low, cutting time is long, cuttage survival rate is low to solve.
Another object of the present invention is to provide carries out with above-mentioned plant growth regulator that F2 is wet to add the method that pine cuttage is grown seedlings, and makes F2 wetly add pine cuttage rooting rate height, cutting time is short, cuttage survival rate is high.
For achieving the above object, solution of the present invention is:
F2 is wet to add the pine cuttage plant growth regulator of growing seedlings, formed by following formulated: IBA (indolebutyric acid) 800mg ± 40mg, NAA (methyl) 400mg ± 20mg, catechol 5.5mg ± 0.5mg, KT (6-chaff aminopurine) 0.02mg are diluted with water to 830ml.
Described F2 is wet to add the pine cuttage plant growth regulator of growing seedlings, specifically formulated by IBA 800mg, NAA 400mg, catechol 5.5mg, KT 0.02mg.
Carry out with above-mentioned plant growth regulator that F2 is wet to add the method that pine cuttage is grown seedlings, the plugged ear of gathering semi-lignified earlier, length is 6-14cm, after sterilization is pruned, carries out speed with above-mentioned plant growth regulator solution again and dips in processing, the time is 5 seconds; Carry out cuttage and seedling culture then, the temperature in the seedling growth greenhouse is controlled at 10-30 ℃, and relative moisture is at 85%-95%, and ventilates 2-3 time every day according to weather condition.
The present invention adopts above-mentioned plant growth regulator to carry out that F2 is wet to be added pine cuttage and grow seedlings; solved that F2 is wet to add problems such as the pine cuttage rooting rate is low, cutting time is long, cuttage survival rate is low; not only can take root ahead of time; and 80 days rooting rates can reach 85%, 100 day more up to 92.5% after cuttage, and average growing-seedling period was at 120 days; shorten growing-seedling period 10 days; cuttage survival rate has greatly reduced seedling cost up to more than 90%, for the scale breeding is laid a good foundation.
Embodiment
Material selection of the present invention: adding pine and give birth to the super seedling that grows directly from seeds half a year as adopting the fringe maternal plant through the F2 of classification is wet, ground, garden select physical features smooth, on the sunny side, wind sheltering, closely water source, excessively drained field.Plugged ear is with semi-lignified, and long 6-14cm is the most suitable during the long 3-5cm of inferior leave, just can be used as experiment material through sterilization, after pruning.
Below by different plant growth regulator handle to plugged ear heal, expand, the difference comparative experiments of rootage duration, and identical plant growth regulator variable concentrations (processings) is for the contrast experiment that influences of plugged ear, proves that growth regulator that the present invention discloses is that F2 wets and adds the optimum growh conditioning agent proportioning that pine cuttage is grown seedlings.
At first be that different plant growth regulator is handled fringe bar wound healing, expanded, the difference comparative trial of rootage duration, rooting rate.

From table 1,2,3,4 comparison, as can be seen, under the cuttage environment condition identical with management method, different chemicals treatment significant differences.When inserting back 40 days, it is not obvious to observe every index difference; When inserting back 60 days, first group (ABT1) and the 4th group (plant growth regulator of the present invention) two kinds of chemicals treatment show remarkable advantages; When inserting back 100 days, plant growth regulator of the present invention is more obvious to the facilitation of growth of cuttage seedlings than ABT1.
Next is identical plant growth regulator variable concentrations to plugged ear wound healing, the influence of expanding, taking root.
Table 5ABT1 root-growing agent variable concentrations (processing) compares for the influence of cuttage rooting
Remarks: plant growth regulator soaking solution concentration of the present invention is for being diluted to 11000ml, and the time is 12-24 hour; Speed is dipped in concentration for being diluted to 830ml, and the time is 5 seconds.
Table 6ABT1 root-growing agent variable concentrations (processing) compares for the influence of cuttage rooting
Remarks: plant growth regulator soaking solution concentration of the present invention is for being diluted to 11000ml, and the time is 12-24 hour; Speed is dipped in concentration for being diluted to 830ml, and the time is 5 seconds.
From table 5,6 contrast after cuttage 40 days as can be seen, to add the influence of pine cuttage seedling rooting little to wet for the ABT1 solution of variable concentrations, and for the expansion of branch head extremely significant difference is arranged, best with the 500mg/L effect.Adopt plant growth regulator processing plugged ear speed of the present invention to dip in rule comparatively remarkable advantages is arranged.
In sum, show through twice test that ABT1 and plant growth regulator of the present invention have short preferably rooting effect, ABT1 concentration effect in 300～800mg/L scope is better; And plant growth regulator of the present invention can be taken root ahead of time than ABT1; 80 days rooting rates can reach 85% after cuttage; 100 days more up to 92.5%; average growing-seedling period was at 120 days; shortened growing-seedling period 10 days, and used growth regulator of the present invention to carry out that F2 is wet to be added pine cuttage and grow seedlings, cuttage survival rate is up to more than 90%; greatly reduced seedling cost, for the scale breeding is laid a good foundation.
F2 of the present invention is wet to be added the specific embodiment that pine cuttage grows seedlings and is: the plugged ear of gathering semi-lignified earlier, be advisable with long 6-14cm, after sterilization is pruned, use following formula I BA (indolebutyric acid) 800mg ± 40mg again, NAA (methyl) 400mg ± 20mg, catechol 5.5mg ± 0.5mg, KT (6-chaff aminopurine) 0.02mg, be diluted with water to and carry out speed in the formulated solution of 830ml and dip in processing, the speed time of dipping in is 5 seconds, carry out cuttage and seedling culture then, temperature in the seedling growth greenhouse is controlled at 10～30 ℃, relative moisture is 85%～95%, and ventilates 2～3 times every day according to weather condition.
