Embodiment 1

[0039] (1) Twig cuttings

[0040] In September, the raw semi-woody branches of the year were used as cuttings, and peat soil, river sand and perlite mixed in a ratio of 2:1:1 were selected as substrates, treated with 1000mg / L IBA for 30 seconds, and the cuttings were placed in full light spray conditions. Next, the spray interval is 15min, and spray 30s. Stop spraying after 20 days of rooting, and adopt the seedling management method: take the substrate humidity as a reference, and when it drops below 50%, spray foliar fertilizer once through sprinkler irrigation until the soil moisture content is above 90% (that is, until the soil water content is above 90%) ). Foliar fertilizer composition is NH 4 NO 3 500mg / L, KNO 3 280mg / L and NH 4 H 2 PO 4 500mg / L.

[0041] (2) Facility cultivation

[0042] In January of the following year, the cutting seedlings were moved to the seedling bed in the nursery shed for cultivation. The size of the nursery shed was 8m*30m, the shoulder height was...

Abstract

The invention discloses a fixed-stem cultivation method for annual cutting seedling of Yakushima lagerstroemia. The method comprises the following steps: (1) cutting a tender twig; (2) performing facility cultivation; (3) stumping; (4) controlling sprout branches; (5) managing water and fertilizer; (6) fixing a stem. When the cultivation method is used for propagating and culturing, the Yakushima lagerstroemia is upright and grows fast; the fixed-stem cultivation period is short; the obtained fixed-stem seedlings have tidy specifications.

Description

Technical field [0001] The invention specifically relates to a method for fixed-drying cultivation of annual cutting seedlings of Lagerstroemia fauriei (Lagerstroemia fauriei), belonging to the technical field of woody plant cultivation. Background technique [0002] Yakushima Lagerstroemia (Lagerstroemia fauriei Koehne.) belongs to Lythraceae (Lythraceae), Lagerstroemia (Lagerstroemia), a small deciduous tree, 3 to 5 meters high. It is a rare tree species for viewing leaves and stems. The trunk is smooth, brown and reddish brown (when the trunk is peeling from July to August). Odd-pinnate compound leaves, 5-9 small leaves, oval, leathery, yellow, red and other colored leaves in autumn. The panicles are large and beautiful, with branch tops, milky white flowers, and blooming from June to July. The fruit is nearly spherical, and the fruit period is September to October. This tree species is an excellent garden ornamental tree species that integrates tree shape, tree posture, t...
