However, this traditional cutting seedling is to directly insert a single branch into the soil at a certain distance, which requires a larger nursery land. To maintain the integrity of the root system, this cutting propagation efficiency is low, the propagation cost is high, and it takes a long time, which affects the propagation speed of dragon fruit cutting seedlings to a certain extent.

Embodiment 1
[0021] A kind of method for quickening pitaya cutting seedling raising process, concrete steps comprise:
[0022] (1) Use branch scissors to cut off mature dragon fruit branches with a length of about 30cm, and use a sharp knife to cut the three-edged or four-edged stems of the branches obliquely into wedges at a distance of 5cm from the lower cut of the matured branches, exposing the middle The vascular bundle is about 1cm, and soaked in 600 times thiophanate-methyl liquid for 1 minute to eliminate germs, take it out and place it in a cool place for 7 days to allow the wound to dry and heal.
[0023] (2) Tie 10 dragon fruit branches into a bundle with cloth strips or braided ropes (open the head and tail separately), put the wedge-shaped end neatly, and uniformly immerse this end in 1200ppm of indole Deep into 5cm of doxylbutyric acid liquid for about 1 minute.
[0024] (3) Spread a layer of sand with a thickness of 3cm on the ground, water it to keep it moist (keep the wate...

Abstract
The invention belongs to the technical field of agricultural cultivation, in particular to a method for accelerating the process of cutting and seedling raising of pitaya. The method includes immersing wedge-shaped pitaya branches in a 600-fold methyl tobuzin liquid for 1 minute, bundling the wedge-shaped branches into a bundle with cloth strips or braided ropes, placing the wedge-shaped ends neatly, uniformly immersing the end into a 1200ppm indolebutyric acid liquid, laying a layer of sand with a thickness of 3cm on the ground, watering for moisturizing, placing the end of the whole bundle of pitaya branches stained with a rooting agent directly on the sand vertically, and squeezing and erecting other bundles of branches together; and watering once every 3 days, after 15 days, coming out, by the cuttage seedlings, of the nursery when 3-5 root systems with a length of 5-8cm grow out of the lower end of the branches; when the cuttage seedlings come out of the nursery, lifting and removing the whole bundle of cuttage seedlings for planting. The method has the advantages of fast propagation time of 30 days and fast propagation speed, and the cuttage propagation is most suitable for large-quantity cuttage propagation of pitaya because the technology is simple and easy to master, and the original variety characteristics can be maintained.
Description
technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a method for accelerating the progress of dragon fruit cutting seedling cultivation. Background technique [0002] Dragon fruit [Hylocereus undatus spp.], also known as red dragon fruit, xianmi fruit, lover fruit, sesame fruit, etc., is a perennial climbing succulent plant belonging to the genus Hylocereus undatus of the family Cactaceae. , subtropical fruit trees, originated in the tropical rain forests and deserts of Central America, artificially cultivated in tropical areas of Central America, Israel, Vietnam, Thailand, the United States and other countries, and in mainland China for more than ten years in Guangxi, Guangdong, Hainan, Guizhou Cultivation has sprung up in , Yunnan, Fujian and other places, with a development area of about 750,000 mu, with a strong development momentum and broad prospects. [0003] Because dragon fruit is a whip-li...
