Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a pitaya single-thorn grafting method for the shortcomings in the traditional grafting technology that the number of plants cannot be rapidly expanded for scarce excellent varieties, and when the rootstock or scion is too old, the grafting is difficult to survive.

Embodiment 1

[0019] The applicant carried out the grafting test in the dragon fruit test greenhouse of Guangxi Institute of Botany in 2012. The specific grafting method is as follows:

[0020] 1) In June, when the temperature is between 25 and 28 degrees, in a ventilated room, select the white-fleshed pitaya stems that have grown roots and grow thickly as rootstocks, and the red-fleshed mature pitaya branches as spikes;

[0021] 2) Find a thorn seat on the rootstock, and cut the thorn seat with two cuts. Specifically, select the thorn seat in the middle and upper part of the rootstock, and cut obliquely and longitudinally on the upper and lower sides of the thorn seat. The depth of the incision should not touch the xylem It is advisable to control the incision angle at 90°;

[0022] 3) Look for a complete thorn seat on the ear bar, and cut off the thorn seat as a scion with the two-knife method. Specifically, cut one obliquely longitudinally on the upper and lower sides of the selected tho...

Embodiment 2

[0026] The applicant carried out the grafting test in the pitaya orchard of Pingguo County, Guangxi in June 2012. The specific grafting method was the same as in Example 1, except that the angle between the scion and the rootstock incision was controlled at 70° to 80°.

[0027] The scion began to germinate within 45 to 52 days after the bag was removed, and the statistical survival rate was 92%.

Abstract

The invention discloses a single-thorn grafting method for pitaya. The single-thorn grafting method is carried out at the temperature of more than 20 DEG C from March to October each year, and concretely comprises the following steps: 1), selecting a stock and a scion for grafting; 2), looking for an areole on the stock, cutting off the areole, and controlling the cut angle to be 60-90 DEG; 3), looking for a complete areole on a mature branch of the pitaya, cutting off the areole to serve as the scion, controlling the cut angle to be 60-90 DEG C, and keeping the cut angle to be the same as that of the stock to the greatest extent; 4), inserting the scion into a stock cut, and binding by a binding tape for finishing grafting; and 5), bagging the grafted pitaya branch for 5-10 days, removing bags, and after the scion grows normally, carrying out routine management. According to the single-thorn grafting method, the single areole is used for grafting the pitaya, so that the number of plants can be quickly increased and the problem of aging of the stock and the scion in the conventional grafting method can be also solved; and the scion and the stock are easily bonded with each other, so that the survival rate is more than 90%.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a dragon fruit single thorn grafting method. Background technique [0002] Dragon fruit is a plant of the genus Trigonum in the family Cactaceae. Because of its soft scales on the outside of the fruit, it is called dragon fruit, also known as red dragon fruit and fairy honey fruit. It is native to tropical Central America. The dragon fruit plant is a perennial climbing succulent plant with a triangular-shaped stem. The fleshy stem is dark green and shiny, and becomes the main organ of photosynthesis. The propagation of dragon fruit is currently mainly carried out by seeds, cuttings, grafting, etc. Among them, a large number of seedlings can be obtained by sowing seeds of dragon fruit, but the plant traits of seeds propagated are relatively differentiated. At present, the cutting propagation method is more used in production, which can produce a large number of exc...
