Embodiment Construction

[0016] Below in conjunction with specific embodiment, further set forth the present invention:

[0017] The cutting propagation method of multi-scale vanilla comprises the following steps:

[0018] 1) Select the robust stems of Vanilla polylepis, and intercept robust cuttings containing 3-5 nodes (the internodes are shorter, such as shorter than 3cm, 5 nodes can be intercepted; the thickness of the cuttings is preferably more than 0.3cm );

[0019] 2) inserting 2-3 nodes at the lower end of the cuttings into the substrate, and making the substrate and the cuttings contact densely, and the substrate is construction sand with a particle size of 0.5-2mm;

[0020] 3) Select a shade shed with a shading degree of 40%-60% on the top and sides, and control the growth conditions at a humidity of 40%-80% and a temperature of 18°C-30°C;

[0021] 4) Water thoroughly for the first time after cutting to make the substrate reach the saturated water content of the field, and then water once...

Abstract

The invention discloses a cutting propagation method for a Vanillinae plant namely Vanilla polylepis. The cutting propagation method comprises the following steps: 1) selecting robust stems of the Vanilla polylepis, and cutting the stems so as to obtain a robust cutting with 3 to 5 nodes; 2) inserting 2 to 3 nodes of the lower part of the cutting into a substrate, and allowing the substrate to compactly contact with the cutting, wherein the substrate is building sand with a particle size of 0.5 to 2 mm; 3) selecting a sunshelter with the top part and the side surface having a shading degree of40% to 60%, and controlling growth conditions, wherein a humidity is controlled to be 40% to 80%, and a temperature is controlled to be 18 DEG C to 30 DEG C; and 4) after completion of cuttage, carrying out complete watering for the first time, and then carrying out watering every 10 days. The method provided by the invention is simple and practicable, can reach a rooting rate of 80% or above, and is applicable to mass propagation of the Vanilla polylepis.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a vegetative cutting propagation method of vanilla versicolor. Background technique [0002] Vanilla polylepis is a plant of the Orchidaceae vanilla genus, distributed in Congo, Kenya, Angola, Malawi, Zambia, Zimbabwe and other southeastern African countries, where it grows between 1200 meters and 1500 meters above sea level It is found in small quantities in the warm forests of China and even in forests at an altitude of 2000 meters. This plant belongs to the climbing herbaceous plant, likes a semi-shady environment, with fleshy leaves, smooth leaves and stems, internode length up to 15 cm, stem diameter up to 2.5 cm, flower diameter up to 12 cm, fruit The pods are up to 15 cm long and 1.5 cm wide, and the flowers and fruits are relatively large in this genus. [0003] The fruit of the vanilla plant is called the vanilla bean, which is the raw ...
