Embodiment example 1

[0017] Select nursery land: choose flat terrain, convenient transportation, irrigation water, fertile soil, good air permeability, pH 5.0~8.4, and convenient drainage.

[0018] Prepare the scion: choose excellent scion and rootstock, among which the scion chooses the annual branch or the current year branch with full bud body, moderate length of node, no pests and diseases, fully lignified or semi lignified as scion. The scion is divided into winter ear, spring ear and summer ear according to different collection periods, and wherein, the collection of winter ear is: after the landscape color poplar of the present invention has fallen leaves, the scion cut out takes cellar sand storage or cold storage preservation, every 50 ears The strips are bundled into a bundle, and two-thirds of the cellar sand is buried in wet sand, which can be stored until mid-April, stored at 1-5°C in a cold storage, and can be stored until late July; the collection of spring ears is: in the landscape ...

Abstract

The invention discloses a grafted breeding technology, and provides a process specification for grafted breeding on landscape red-leaf populus deltoids of a new variety. The grafted breeding technology is realized through the steps of nursery land selection, preparation of scions and stocks, grafting, nurturing management and pest control and prevention. The technology is simple in process and high in survival rate of breeding, seedlings are healthy, grafted breeding can be conveniently performed on the landscape red-leaf populus deltoids, and then the landscape red-leaf populus deltoides canbe effectively cultured to be applied and popularized.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a grafting technology, in particular to a grafting and breeding technology of colorful poplar for landscape use. Background technique [0002] The landscape colorful poplar in the present invention is a new variety of red-leaf poplar selected from the bud change of Zhonglin 2025 poplar. It belongs to American black poplar. The male has no flying catkins. The leaves are bright red at the germination stage, and gradually become orange-red as they grow, and then yellow-green. It is orange-red or orange-yellow before falling leaves, and the petioles, leaf veins, dry stems, and new shoots are always red. The color is bright and attractive, and has high ornamental value. The landscape colorful poplar in the present invention has the advantages of easy cultivation of poplar and strong adaptability, and can be widely used in gardens and road greening, and can also be used as ...
