Method for quickly breeding pitaya seedlings

Abstract

The invention relates to a method for quickly breeding pitaya seedlings. The method comprises the following steps: building seedbeds in a plot with ventilation, exposure to the sun, no pollution source around and irrigation and drainage convenience, wherein perlite is utilized as the matrix of the seedbeds, and constructing an automatic water spraying system; preparing rooting liquid with No. ABT1-6 rooting powder, soaking in vitro pitaya stems in the rooting liquid, and inserting the soaked stems into the seedbeds; and finally properly controlling a water pump to spray water to the in vitro pitaya stems according to the humidity and temperature environment of the seedling breeding field until the stem bases root, and transplanting the rooting stems into a field for cultivation. Through the implementation of the invention, few materials are used for breeding the pitaya seedlings; and the perlite, used as the seedling breeding matrix, has the advantages of good permeability and strong moisture retention so that callus of the in vitro pitaya stems and roots can be quickly formed, and the purpose of forming roots and seedlings as fast as possible is achieved. Automation is realized during the seedling breeding, and therefore, management labors are greatly saved. Through implementation of the invention, the seedling breeding is not limited by the seasons and can be performed all year round, therefore, the industrialized production, large-scale and intensive production of pitaya seedlings can be facilitated.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for quickly raising dragon fruit seedlings. technical background [0002] Pitaya is a plant of the genus Trigonum in the cactus family. Native to Brazil, Mexico and other Central American tropical deserts, it is a typical tropical plant. Dragon fruit is rich in nutrients and has unique functions. It contains vegetable albumin and anthocyanins, which are rare in general plants, and is rich in vitamins and water-soluble dietary fiber. Its fleshy scales on the outside resemble the outer scales of a dragon, and when the huge flowers bloom, the fragrance is overflowing, which makes people feel auspicious, so it is also called "auspicious fruit". Dragon fruit ranks high among the edible plant fruits of human beings, and it implies auspiciousness, health, wealth, longevity and many other ideals of human beings. Whether people are visiting relatives and fr...

Problems solved by technology

The grafted seedling propagation method has a fast seedling growth rate, but the process is cumbersome, and many rootstock parent materials are used, resulting in high production costs for finished dragon fruit seedlings

Weaving culture and reproduction can quickly reproduce and detoxify, improve the quality of seedlings and the number of reproduction, but the investment in infrastructure equipment required is large, and the technical process is professional and complicated, and the cycle of forming finished seedlings is longer
