Problems solved by technology

At present, bougainvillea tissue culture technology has not formed a relatively complete technical system, and it is rarely used in actual production. The grafting and layering propagation procedures are complicated, and it is difficult to reproduce seedlings in large quantities. Cuttings have become the most important propagation method of bougainvillea.
There have been many reports on the cutting propagation of Bougainvillea bougainvillea, but mainly for twigs or semi-lignified branches, focusing on the rooting rate of cuttings, exploring the types and characteristics of rooting, and improving the rooting quality of lignified cuttings and the survival rate of cuttings transplanted. Research rarely reported
According to existing research reports, Bougainvillea cuttings are easier to root, but generally the number of cuttings rooting is small, the requirements for management and maintenance after transplanting are high, the survival rate is low, the time for slowing seedlings and seedlings is long, and the cost of seedling cultivation is high.

Abstract

The invention belongs to the technical field of plant propagation, and particularly relates to a method for promoting rooting of bougainvillea-glabra lignifying cutting slips. The method includes the following steps of seedbed building, plastic arched-shed constructing, cutting slip selecting and preparing, cutting slip pre-treating, inserting, post-inserting managing and transplanting. According to the method, after bougainvillea glabra is inserted, the average rooting number can be larger than 100, the rooting rate can be higher than 98%, and the survival rate of transplanting can be higher than 96%; the method is simple and easy to operate, and can be further applied and popularized in bougainvillea glabra seedling growing.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for promoting the rooting of bougainvillea lignified cuttings. Background technique [0002] Bougainvillea (Bougainvillea glabra), also known as bougainvillea, bougainvillea, bougainvillea, etc., is a plant of the genus Bougainvillea in the family Nyctaginaceae. The flowers are small, often clustered in three, and the bracts are large and showy, with various colors such as purple, red, white, and yellow, and are the main ornamental parts. Bougainvillea is native to tropical and subtropical South America. It was introduced into China in 1872. It is an important ornamental flower and an excellent landscaping plant. It can be used for arbors, easels, fences, and potted plants. It blooms continuously all year round in Guangxi, Guangdong, Fujian, and Hainan, and is deeply loved by people. Now it has become the city flower of Shenzhen, Xiamen, Wuzhou, Be...
