Multilayer tree cultivation method under condition of Zelkova serrata (Thunb.) Makino interplanting

Abstract

The invention discloses a multilayer tree cultivation method under the condition of Zelkova serrata (Thunb.) Makino interplanting, belonging to the field of tree cultivation. The method comprises the following steps of: firstly, transplanting and permanently planting 3-year-old to 5-year-old Zelkova serrata (Thunb.) Makino seedlings in March, keeping plant spacing for permanent planting to be 150cm to 180cm and the row spacing and applying additional fertilizer for three to five times per year; then planting one 30cm-tall to 35cm small Photinia fraseri seedling between every two Zelkova serrata (Thunb.) Makino, keeping the small Photinia fraseri seedlings in a row in a transverse direction and a line in a longitudinal direction, and pruning Photinia fraseri in early summer of every year; and finally, planting Othiopogon japanicus on the two sides of the Zelkova serrata (Thunb.) Makino and the Photinia fraseri in each field, and applying additional fertilizer for one to two times per year. Compared with a single plant cultivation method, the method disclosed by the invention has the advantages that the land resource is utilized more effectively, a small ecological environment is formed, diseases and insects are reduced, the virtuous cycle of an ecological system is realized, kinds of product varieties are provided at the same time, the social demands in multiple aspects are satisfied and the economic benefit is improved.

Description

technical field [0001] The invention relates to a plant interplanting method, in particular to a multi-layer tree cultivation method under the interplanting of beech trees. Background technique [0002] Beech( Zelkova serrata (Thunb.) Makino ) is a deciduous large arbor tree species of the genus Beech in the family Ulmaceae, and it is a national second-class key protected plant. It is widely distributed in our country, grows fast, and has excellent material quality. It is a precious hard broad-leaved tree species. The beech tree is tall, with a wide crown, dense green shade in midsummer, and red leaves in autumn. It has extremely high economic value and ornamental value in urban greening and garden construction. Beech likes light and is slightly shade-tolerant, and likes warm climate and fertile and moist soil. It grows slowly when it is young, and it grows faster after 6-7 years. Smoke and dust resistance, anti-pollution, less pests and diseases, long life. At present...

Problems solved by technology

At present, beech trees are monocultured in the production process. Although the output of beech trees has been improved by means of density control and transplanting, land resources have not been effectively used.
