Cutting rooting method for epicormic branches of camptotheca acuminata

Abstract

The invention discloses a cutting rooting method for epicormic branches of camptotheca acuminate. The cutting rooting method comprises the following steps: cutting the branches from a big tree and taking as cutting slips, wrapping with a piece of wet cloth and keeping fresh state; straightly cutting the upper notches of the cutting slips, bias cutting the lower notches, maintaining 1-2 leaves on the upper part and cutting off 1 / 2-2 / 3 of the leaves; disinfecting for 2h by adopting 0.1% carbendazim solution, and then treating for 20s-2h by adopting a hormone solution; performing cuttage for epicormic branches on a substrate, and by keeping 8-10cm seed spacing, maintaining the depth of the cutting slips as about 1 / 2 of the length and exposing the first leaf on the substrate; watering after finishing the cuttage; performing labor management, and then performing intertillage weeding per two weeks and spraying 0.1% carbendazim solution for disinfecting; lignifying the roots of the camptotheca acuminate, and then transplanting in time. According to the cutting rooting method for epicormic branches of camptotheca acuminate provided by the invention, a camptotheca acuminate clone seedling system is established, so that the high-quality camptotheca acuminate seedlings are acquired. The method is simple and convenient in operation, is feasible and has the advantages of low cost, simple technical requirement, easiness in popularization and application, and the like.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a rooting method of philodendron twig cuttings. Background technique [0002] Campylodendron belongs to the blue fruit tree family, Campylodon genus, this genus has only one species of camptophylla, which is endemic to my country. The pith-core of the branchlets are separated in sheets, the leaves are papery, oblong-ovate or elliptical, long-elliptic, 12-28cm long, 6-12cm wide, entire, with petioles 1.5-3cm long. Inflorescences terminal or axillary, about 1.5cm in diameter, often composed of raceme-like compound inflorescences, terminal inflorescences with female flowers, axillary inflorescences with male flowers; flowers with 3 bracts, calyx 5-lobed, lash-like edges ; petals 5, 2mm long; anthers 4-celled. Samara, 2-2.5cm long, with a persistent disk at the top and narrower wings on both sides. The flowering period is from May to July; the fruiting period ...
