A kind of dragon fruit list thorn grafting method
Technical field
The present invention relates to the fruit tree planting technique field, be specifically related to a kind of dragon fruit list thorn grafting method.
Background technology
Dragon fruit is Cactaceae triangular prism platymiscium, because 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, graftings 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 larger.Using in producing at present more is the cottage propagation mode, can produce a large amount of choiceness nursery stocks, and more successful experience is arranged, and can solve the problem of breeding of nursery stock in the large-scale development process.But for dragon fruit more rare, outstanding kind, branch own seldom or is only taken several branches, be difficult to expand fast the plant number by cuttage and seedling culture, although and traditional grafting method can more raising kind strain numbers, but because traditional grafting method is received on the stock with the scion of 3~4cm, a branch is divided into after the scion quantity also and is few, and plant quantity that can grafting is still less.In addition, for excessively old stock or scion, owing to center vascular bundle lignification causes flushing, rabbets can't driving fit, grafting is difficult to survive.Therefore need to seek the strain number that a kind of succinct fast method increases rare outstanding kind dragon fruit, simultaneously old dragon fruit scion can be survived smoothly with stock.
Summary of the invention
The technical problem to be solved in the present invention is can't expand rapidly plant quantity, cross when old the deficiencies such as grafting is difficult to survive when stock or scion rare outstanding kind for what exist in traditional graft technology, and a kind of dragon fruit list thorn grafting method is provided.
Dragon fruit list of the present invention thorn grafting method, be March in every year to October, and temperature is higher than 20 and carries out when spending, and specifically may further comprise the steps:
1) select the sturdy plain boiled pork type stems of dragon fruits section of long root and growing way or hylocereus as the grafting stock, the thorn seat on the different cultivars dragon fruit maturation branch is as scion;
2) seek a thorn seat at stock, with two skill in using a kitchen knife in cookery excision thorn seat, the control cut angle is at 60~90 ° of stocks;
3) seek a complete thorn seat at the ripe branch of dragon fruit, downcut this thorn seat as scion with two skill in using a kitchen knife in cookery, the control cut angle is at 60~90 °, and the angle of trying one's best with the stock otch is consistent;
4) scion is inserted the stock otch, suitably mobile so that scion and stock otch are combined closely, carry out colligation to finish grafting with bundling belt;
5) scion was carried out Routine Management after entering normal growth to the dragon fruit bough bagging that grafting is good afterwards except bag in 5~10 days.
Above-mentioned grafting method normally March in every year to October, and temperature carries out when 20~30 spend.
The step 2 of said method) in, described cut angle is preferably 80~90 °.
The step 3 of said method) in, described cut angle is preferably 80~90 °.
The step 4 of said method) in, described bundling belt specifically can be rope, adhesive tape or preservative film etc.
Two skill in using a kitchen knife in cookery described in the said method are the two conventional skill in using a kitchen knife in cookery in the existing graft technology of growing seedlings.Excision on the stock the thorn seat or when the ripe branch of different cultivars dragon fruit downcuts thorn seat as scion, normally respectively each tiltedly vertical partial application in the upper and lower both sides of thorn seat, notch depth is advisable with the xylem that does not injure stock or fringe bar, and the control cut angle is in 60~90 ° of scopes.
Compared with prior art, the method for the invention is used the grafting of single thorn seat, thereby can expand fast the plant number, again owing to be to use the grafting of single thorn seat, thereby the thorn seat that can adopt the dragon fruit bough lower is as scion, thereby avoids sprouting from the trunk lower, and each bud point is made the best use of everything; In addition, for too aging stock or scion, get final product normal growth by single the thorn after grafting method connects, thereby solve anvil in traditional grafting method, fringe problem of aging; Moreover, adopt the grafting of single thorn with the thorn seated connection of improved seeds dragon fruit on relatively poor kind, can also carry out kind and upgrade.
The applicant finds through experiment, adopts above-mentioned single thorn grafting method grafting dragon fruit, and scion and stock are easily bonding, and survival rate is up to more than 90%.
Embodiment
The invention will be further described with specific embodiment for the below, but the present invention is not limited to these embodiment.
Embodiment 1
The applicant carried out Grafting Experiment in 2012 in the dragon fruit test booth in Guangxi Plant Inst., and concrete grafting method is as follows:
1) in June, temperature is when 25~28 spend, and is indoor what ventilate, chooses the sturdy plain boiled pork type stems of dragon fruits section of root of hair and growing way as stock, and the ripe dragon fruit bough of red meat type is as the fringe bar;
2) seek a thorn seat at stock, with two skill in using a kitchen knife in cookery excision thorn seat, the thorn seat of specifically selecting the stock middle and upper part to divide, each tiltedly vertical partial application in the upper and lower both sides of thorn seat, notch depth is advisable not touch xylem, and the control cut angle is at 90 °;
3) seek a complete thorn seat at the fringe bar, downcut this thorn seat as scion with two skill in using a kitchen knife in cookery, specifically each tiltedly vertical partial application in the upper and lower both sides of the thorn seat of selecting, notch depth is advisable not touch xylem, and the control cut angle is at 90 °;
4) scion is inserted the stock otch, suitably move so that scion and stock otch are combined closely, will sting seat colligation consolidation on stock with rope, finish grafting;
5) dragon fruit bough that grafting is good entangles with sack, and fix with rubber band, remove sack after 10 days (when stock and scion solid colour at bagging, show the grafting success), except the bag after 50~60 days in scion begin rudiment, survival rate is 95% by statistics, and scion is carried out Routine Management after entering normal growth.
Embodiment 2
The applicant carries out Grafting Experiment in the dragon fruit orchard of in June, 2012 Pingguo County,GuangXi, concrete grafting method is identical with embodiment 1, and different is that the angle of control scion and stock otch is at 70 °~80 °.
Scion begins rudiment in 45~52 days after removing sack, and survival rate is 92% by statistics.
