Embodiment Construction
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below, but the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] The applicant conducted a grafting test at the Pitaya Test Base (open field) of Guangxi Agricultural Vocational and Technical College from March to August 2013. The specific grafting methods are as follows:
[0025] 1) Cultivate rootstock seedlings by cutting method from March to June;
[0026] 2) Rootstock species: Bawanghua;
[0027] 3) Cutting and processing of cuttings: Select fully mature branches and vines with 1-2 years of age from Bawanghua plants, cut cuttings at 25-30cm, and cut the three edges at the base of cutti...

Abstract
The invention relates to a dragon fruit grafting method, which comprises the following steps of (1) selecting a stock; (2) culturing a stock seedling; (3) cutting an aged branch of the dragon fruit into a branch section with length of 6-10cm as a scion, selecting a ridge, cutting a plane with length of 3-5cm along the xylem part of the ridge from the base part of the branch section, longitudinally cutting one part, and cutting the ridge off; (4) transversely cutting one part at the position, 10-20cm away from ground, of the stock, selecting one stock ridge, longitudinally cutting one part along the xylem part of the ridge to form the depth of 3-5cm, parallelly cutting one part to the outside, enabling the width to be the same as the thickness of the scion, transversely cutting one part at the lower surface of the cutting opening, taking the meaty ridge stem out, and forming a groove-shaped union; (5) inserting the scion into the stock union, aligning the xylem parts, fixing, and binding by a plastic tape; (6) coating a plastic bag on a grafting union, so as to complete grafting; (7) after grafting, performing conventional management. The dragon fruit grafting method has the advantages that the operation is convenient, the speed is high, the stress resistance property and suitability of the plant can be improved, the disease and pest resistance capability is improved, the adhering of the scion and the stock is easy, and the survival rate reaches 97%.
Description
technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a dragon fruit grafting method. Background technique [0002] Pitaya is a perennial climbing succulent plant of the genus Hylocereua 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. Produced in the tropical regions of Central America, the branches and tendrils are triangular in shape, and the fleshy branches and tendrils are dark green and shiny, becoming the main organ of photosynthesis. There are two ways of reproduction of dragon fruit: sexual reproduction and asexual reproduction. Due to the low germination rate of sexually propagated seeds, the propagation speed of sowing seedlings is very slow, and its genetic basis is relatively complicated, so it is not easy to maintain its variety characteristics. Therefore, the production of dragon fruit main...
