Abstract
The invention discloses a method for inducing a stem segment of dragon fruit to rapidly root. The method comprises the following steps: 1) clipping a branch of mature and strong dragon fruit with age of one to two years as a root accelerating stem segment; 2) beveling a section on the lower part of the root accelerating stem segment and placing the root accelerating stem segment at the shady, cool and ventilated position until a wound is healed; 3) soaking the root accelerating stem segment the wound of which is healed in a soaking liquid for 8-15 hours, wherein the soaking liquid is prepared by the following method: dissolving 400-600mg of indolebutyric acid and 400-600mg of naphthylacetic acid in a small amount of ethanol, and then adding water until the volume is 1000ml; and 4) taking out the root accelerating stem segment from the soaking liquid and then placing the root accelerating stem segment in the shady, cool and ventilated position for 25-35 days until the rooting degree reaches transplanting requirement, wherein during the placement, the indoor temperature is maintained to 20-35 DEG C, and the relative humidity is 65-90%. The method disclosed by the invention is simple to operate and shorter in seedling time; and a root system is early germinated, rooting rate reaches more than 90%, and the average rooting number is 10 roots/stem segment.
Description
Technical field
The present invention relates to the micropropagation of plants technical field, be specifically related to a kind of method of inducing flue stem end section to take root fast.
Background technology
Dragon fruit is a Cactaceae triangular prism platymiscium, because of its soft scale of fruit appearance tool such as imperial shape are rolled up, so claim dragon fruit, has another name called red dragon fruit, celestial mamoncillo outward, originates in torrid areas, Central America.The dragon fruit plant is perennial climbing succulents, the climing triangular shape that is of stem, and Carnified stem is dark green glossy, becomes photosynthetic major organs.The breeding of dragon fruit is mainly undertaken by modes such as seed, cuttage, grafting, the cultivations of stem section at present, and wherein, the dragon fruit planting seed can obtain a large amount of seedlings, but the differentiation of the tree characteristics of seminal propagation is bigger.Using in producing at present more is the cottage propagation mode, can produce a large amount of choiceness nursery stocks, and the comparison successful experience is arranged, and can solve the problem of breeding of nursery stock in the large-scale development process.But easy and the most cheap dragon fruit seedling-cultivating method is that the stem section is cultivated at present, and the key that the stem section is grown seedlings is that the stem section is taken root, and could guarantee after the stem section is taken root that the stem section is sprouted sprouting and stalwartness is grown up.But it is all simple relatively that existing flue stem end section is cultivated, and traditional method is that the flue stem end section that clip gets off is dried in the air the back a little with regard to directly cuttage in the ground or in the seedling medium, it is many at 40～50 days that the stem section is germinated the new root time, time is longer, simultaneously, stem section rooting rate is not high, and root quantity is less.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rooting rate height and the many methods of inducing flue stem end section to take root fast of root quantity.
Method of inducing flue stem end section to take root fast of the present invention may further comprise the steps:
1) clip generated the dragon fruit bough of ripe stalwartness in one to two year as the short stem section of taking root;
2) be placed on the shady and cool ventilation place at the short stem pars infrasegmentalis of the taking root section of cutting sth. askew, until wound healing;
3) the short stem section of taking root of getting wound healing places soak to soak 8～15h, and described soak is prepared by the following method: get indolebutyric acid, each 400～600mg of methyl, be dissolved in the small amount of ethanol, add the water constant volume to 1000ml, promptly;
4) from soak, take out the short stem section of taking root place indoor shady and cool placement after 25～35 days the degree of taking root reach the requirement of transplanting; Wherein, keeping indoor temperature between resting period is 20～35 ℃, and relative moisture is 65～90%.
In the said method,
In the step 1), dragon fruit bough throughout the year can clip, carries out after fruiting period finishes better usually, and the time of clip is preferably in annual 4～November, and temperature is to carry out more than 20 ℃ the time.The short stem section of taking root should keep length between 15～60cm, the then easy more recovery growth of stem Duan Yuechang, but oversize as the stem end section, the stem hop count is with regard to corresponding minimizing, and the stem segment length of preferably will urging to take root is chosen for 30～40cm.
Step 2) in, the time of wound healing generally needs 5～8 days.In this step, the section of the short stem pars infrasegmentalis of taking root also can be the plane, just selects the inclined-plane for the contact area that increases section and soak.
In the step 3), when soaking, preferably make the angle section of the short stem section of taking root be positioned at the following 3～5cm of soak liquid level.
In the step 3), the described short soak time of stem section in soak of taking root is preferably 10～12h.
In the step 3), it is 60～100% ethanol that described ethanol is selected volumetric concentration usually for use, and consumption is generally 80～120ml.
In the step 4), preferably keeping indoor temperature between resting period is 25～30 ℃, and relative moisture is 75～85%.
Adopting the method for the invention that dragon fruit is carried out the stem section cultivates, the short stem section of taking root of dragon fruit is taken out from soak and was placed about 7 days, root system begins to sprout, rooting rate can reach more than 90% after placing 25～35 days, the number of on average taking root reaches more than the 10/stem section, and the stem section of wherein taking root good can be directly used in plantation.Compared with prior art, the method for the invention is simple to operate, and it is many that root system is sprouted morning, rooting rate height, root quantity, and seedling raise period is shorter.
