Method for grafting crab cactus by taking pitaya as stock

Abstract

The invention discloses a method for grafting crab cactus by taking pitaya as a stock. The method includes selecting a pitaya plant which is free from pests and diseases and grows robustly, removing the lower end, cutting the lower end into a stem segment with a flat opening, inserting the stem segment in a medium for culture for 1-2 months, and after survival, taking the stem segment as a stock;cutting off part of pulp at 45 degrees along a central vascular bundle on the external diameter of the stock to form a wedge type groove, and causing the wedge type groove to go deep into the centralvascular bundle of the stock; selecting an annual green and healthy crab cactus twig having no diseases and no pests and a telome as a cion, cutting the two sides of the lower portion of the cion intoa wedge shape, and exposing the white central vascular bundle; wedging the lower portion wedge type cut surface of the treated crab cactus cion into the wedge type groove of the crab cactus stock, and fixing the crab cactus cion to make the crab cactus cion closely combined and not loosened; shading the grafted plant, keeping the wound avoiding contacting with water for half a month, if the cionis not shrunk in a week after the grafting, applying an appropriate amount of fertilizer 10 days after the grafting. The method has the advantages of simple operation, high graft survival rate, strongdisease resistance and long flowering period.

Description

technical field [0001] The invention belongs to the technical field of flower cultivation, and in particular relates to a method for grafting orchid orchids with dragon fruit as a stock, which has the advantages of simple operation, high grafting survival rate, strong disease resistance and long flowering period. Background technique [0002] Dragon fruit is a perennial climbing succulent plant of the Cactaceae (Cactaceae) genus Hylocereua. It is native to Brazil and other Central American tropical desert areas. , so it is called dragon fruit, also known as red dragon fruit, fairy honey fruit, Chinese fire Yingle, and dreadlocks. [0003] Crab claw orchid (scientific name: Zygocactustrumcatus (Haw) k.schum.) is an epiphytic succulent plant of the genus Zygocactus Trumcatus, also known as Christmas cactus, crab claw lotus and fairy finger flower. The pendant stems of Crabella are nodular, tender green, and the new stem nodes are reddish. The main stem is round, easy to ligni...

AI Technical Summary

Problems solved by technology

Among them, the cutting method is widely used in actual production due to its simple operation. However, due to the underdeveloped root system of Crabella orchids, the plants after cutting grow very slowly, which often leads to a delay in flowering time and a small number of flowers. Flowers of the same variety and color can be produced, but the ornamental value is insufficient. In addition, the seedlings propagated by cuttings have poor resistance, serious diseases, and low yield

Although the medium cultivation method has fast reproduction and uniform traits, it also has the problems of high initial investment and single flower color per plant.

In the prior art, Prickly Orchid also has the effect of grafting on succulent rootstocks such as prickly pears and cactus to achieve a variety of flower colors. However, due to the cumbersome grafting process and the thicker flesh of prickly prickly pears, the scion of Prickly Pear is often far away. The xylem of the rootstock, so it is difficult to obtain enough nutrition, resulting in low survival rate, few flowers and short flowering period after grafting

Although there are also other less-meat rootstocks that are used to graft Crabella scion to solve the above problems, but due to the limitation of the source of the rootstock, not only the grafting cost is high, but also the operation is complicated; The rate is not high and the number of flowers after survival is small and the flowering period is short
