Cultivation method of small potted plants of bougainvillea spectabilis

Abstract

The invention relates to the technical field of cultivation of bougainvillea spectabilis, in particular to a cultivation method of small potted plants of bougainvillea spectabilis. The cultivation method of the small potted plants of the bougainvillea spectabilis comprises the following steps: (1) selecting dwarf bougainvillea as stock plants of the small potted plants; (2) strengthening management on the stock plants to promote germination of new buds; (3) collecting green sprays which germinate in the present year from the peripheries of crowns of the stock plants; (4) taking top end parts of the sprays as cuttings, and cutting the cuttings into flower soil blocks; (5) placing the flower soil blocks subjected to cutting into a plug, and then placing the plug on a water curtain greenhouseseedbed for root induction; and (6) after the cuttings grow roots, transplanting the cuttings into a plastic greenhouse for cultivation to form the small potted plants of the bougainvillea spectabilis. According to the cultivation method of the small potted plants of the bougainvillea spectabilis, by collecting the sprays on the peripheries of the crowns of the dwarf bougainvillea variety from July to August for cutting propagation, due to the fact that the sprays are subjected to flower bud differentiation before cutting, the flowering small potted plants of the bougainvillea spectabilis canbe obtained in October in the present year; and the heights of the small potted plants which are cultivated for a year can be controlled within 30 cm, and the small potted plants flower for multipletimes, cam be used for being placed indoors, and can be applied into municipal green walls and urban flower putting and hanging.

Description

technical field [0001] The invention relates to the technical field of bougainvillea cultivation, in particular to a method for cultivating bougainvillea small potted plants.

Problems solved by technology

The above methods are cumbersome and costly, and because the cutting bed is placed directly on the ground, it is easy to be infected with germs due to soil disinfection.

In terms of moisturizing measures, in order to keep the cuttings moist, the published patent document "A Method for Rapid Propagation of Bougainvillea" (publication number CN105409509A) adopts the method of putting the cuttings into a grid tray, and then placing the tray on a plastic basin that can store water. ; Public patent document " a kind of propagation method of Bougainvillea cuttage with flower mud " (publication number CN107018791A) will insert the flower mud block of Bougainvillea cuttage into tray, cover with transparent plastic cover, put in enough In an environment with scattered light, keep the temperature above 20°C; these two methods are feasible for a small amount of cuttings, but it is difficult to apply them in large-scale production

The published patent document "A Method for Promoting Rapid Rooting of Bougainvillea Twigs" (publication number CN108207466A) uses lightweight foam to make floating boards, uses the year's long branches as cuttings, inserts the cuttings into the floating board and floats on a wide and clean water surface exposed to direct sunlight Carry out long roots; this method is feasible in the north (Xi'an), but in South China, the cuttings are easy to lose water and dry out due to summer sun exposure

Published patent document "Bougainvillea flower mud matrix cutting method" (publication number CN104255235A) After cutting with flower mud block, place it on river sand with a thickness of about 2cm, then cover flower mud with river sand, water thoroughly, and then water every 2 days Water once; but covering with river sand for moisturizing increases the chance of bacterial infection
