Bougainvillea spectabilis willd cuttage and quick-propagation method

Abstract

The invention pertains to gardening plant propagation technological field, in particular to a fast cutting propagation method of bougainvillea spectabilis. The method comprises seedbed construction, selection and treatment of cuttings, curing management, etc.. With a thickness of 25-35mm, perlite is used as the stroma of the seedbed; the lengths of the treated cuttings are 8-12cm, the cuttings are evenly inserted into the stroma of the seedbed at a depth of 4-6cm based on certain plant and row spacing, along with scientific curing management, cotton yarns or straws are covered between the cutting seedlings for water absorption and heat preservation, new roots of the cuttings are initially formed after 14 days, and seedlings grow out after 30 days, then acclimatization and transplantation can be carried out. The invention, combined with the seedbed construction, treatment with plant growth liquid and scientific curing management technology, greatly shortens the rootage and seedling time of the cuttings with obvious rootage effect by robust taproots and high survival rate; besides, the invention is simple and easy to apply, easy and convenient to manage and has high economic benefit without occupying arable land.

Description

technical field [0001] The invention belongs to the technical field of propagation of horticultural plants, and in particular relates to a rapid propagation method of bougainvillea by asexual cuttings. Background technique [0002] Bougainvillea spectabilis belongs to the genus Bougainvillea of ​​Nyctaginaceae, native to Brazil, and is also known as bougainvillea, bougainvillea, bougainvillea, etc. Bougainvillea is a perennial evergreen vine and likes a warm, humid and sunny environment; it is not resistant to water and humidity, but can tolerate barrenness and drought. Bougainvillea has good-looking flowers, strong ornamental value, long green flowering period and open seasons, so it is often used as lawn decoration plants, hedge plants and flower trellis plants. In addition, bougainvillea has strong functions of vacuuming and drug absorption, and can be used to purify the air, green and beautify the environment; cuttings are one of the main propagation methods of bougainv...

Problems solved by technology

However, from the perspective of the existing technology, there are generally a series of shortcomings such as high requirements for cutting branches, the need for perennial bio-semi-lignified old stems, and the selection of seedbed locations is also relatively limited, and the time is long and the survival rate is relatively low.
