Description

Sedum short-shoot cutting cultivation method

Technical Field

The invention belongs to the technical field of plant cultivation, and particularly relates to a sedum short-shoot cutting cultivation method.

Background

The plant of Crassulaceae is perennial root herbaceous flower with stem upright or creeping, plant height of 20-50cm, and thick underground stem. The sexual pleasure is a strong light and dry, well ventilated environment, and can endure the low temperature of-20 ℃. The soil is barren and drought resistant and has no strict requirement on soil. The flowers are bright and vivid, have various colors such as pink, yellow and the like, and nearly 500 plants belong to the same genus. In recent years, through artificial selection and natural selection, the variety is more diversified, the main cultivated varieties comprise different varieties of sedum aizoon, sedum notoginseng, sedum germanica and the like, and the method is widely applied to landscaping at present. Planting or planting ground cover plants in pieces, arranging flower beds and flower mirrors for hedges and flower bed rims, and potting for courtyard display and landscaping.

Crassulaceae plants can be propagated sexually and asexually. Sexual propagation, namely sowing propagation, greenhouse sowing can be carried out all the year round, coated seeds, sowing substrates (multipurpose turf substrates), hole trays and the like are needed, and management after sowing needs watering, fertilization, rooting promotion and the like besides requirements on temperature, illumination, air humidity and the like. The invisible propagation mainly comprises cutting propagation, leaf cutting propagation, root division propagation and the like. Wherein, the cuttage propagation generally needs the conditions of 6-7cm of cutting slips, 2-3 sections with 2 pairs of leaves, 2-4cm of cuttage depth, a plug tray, a nutrition pot, rooting powder, a substrate and the like, and the post-management of water spraying, fertilizer application and the like needs to be controlled after the cuttage propagation. The management after the leaf cutting has important influence on the survival of the cutting and has stricter requirements on conditions.

Short shoot cuttings are common in either leafy arbors or small arbors. Succulent plants are susceptible to water loss, and thus, water supply is excessive, air humidity is high, temperature is high, and the succulent plants are easy to rot, so that cutting conditions generally need long cuttings of about 7 cm.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, provides a sedum short-shoot cutting cultivation method, and solves the technical problems of low utilization rate of sedum aizoon stock plants, complicated cultivation procedures and easiness in decay in the conventional sedum aizoon propagation and cultivation method.

A sedum short shoot cutting cultivation method comprises the following steps: it comprises the following steps:

1) cutting collection and pretreatment: selecting sedum aizoon with good growth vigor, and cutting the sedum aizoon into small sections with the length of 2-2.5 cm, wherein the number of leaves in each section is 2;

2) preparing a matrix: fully mixing turf and vermiculite in a mass ratio of 5:1 to prepare a matrix;

3) cuttage: filling the substrate prepared in the step 2) into a plug tray to enable the filling amount to account for 3/4 of the capacity of the plug hole, and then inserting the cutting slips pretreated in the step 1) into the substrate to the insertion depth of 1-1.5 cm;

4) cultivation environment management: the method comprises the step of cultivating the short spikes in the scenic days in an environment with the air temperature of 25-32 ℃, the air humidity of 50-65%, the substrate humidity of 30-40%, the shading degree of 50% between 12:00 and 14:00 every day and the shading degree of 30% in the rest time, wherein the cultivation time is 25-35 days.

Further, the three sections at the head end and the three sections at the tail end are removed during the collection of the cutting slips, and the cutting slips are collected from the middle section.

Furthermore, the method is suitable for sedum aizoon, sedum decumbens and sedum aizoon.

The method shortens the length of the conventional sedum rosea cutting from about 7cm to 2-2.5 cm, adopts short cutting to cultivate the sedum rosea, and improves the utilization rate of the sedum rosea stock plant; meanwhile, the middle section of the sedum branch is used as the cutting, the conditions such as substrate proportion, substrate humidity, air humidity, temperature, illumination and the like are controlled, the requirements of the cutting on air and water are balanced under the condition that rooting powder and the like are not adopted for treatment, the culture temperature is properly increased to promote rooting, magnesium and phosphorus in the substrate can be controlled to be at proper levels through controlling the consumption of vermiculite and the substrate humidity under the condition that no fertilizer is added, the rotting of the sedum meat stem is effectively inhibited, the manpower, material resources and time investment in the culture process are reduced, and the survival rate is increased. Compared with the prior art, the method has the advantages of high utilization rate of the Jingtian maternal plant, simple cultivation process, high survival rate and the like.
