Method for cultivating cutting seedling of Zelkova serrata

Abstract

A method for cultivating cutting seedlings of Zelkova serrata comprises following steps: a). at the mountainous area in the southern Anhui with 500-3000 altitude, select a plot with deep soil and more humus for reclamation; b). at 2-4 month of every year, select annually vegetative growth branches of locally growth Zelkova serrata with more than 20 years old as cutting branches; c). after disinfecting the disinfected cutting branches, smear rooting powder on the roots and then insert the cutting branches into a seedbed; d). after generating buds for 8-16 days, spray 500 kilogram of farmyard manure each mu; at the end of May, set up a shading mesh, and timely remove weeds on the seedbed; e). at the autumn of a second year, trim the branches, leave only main branches and cut the other branches for the main branches fully absorbing nutrition in convenient and growing up rapidly; f). after the ground diameter of the seedlings reaches more than 1m, transplant the seedlings and the transplantation should be at autumn; g). and the second year of transplantation should be a dry-keeping period; at spring, stump and cut the seedlings from 5cm above the ground and the cut mouth should be smooth; and at the later growth period, the seedlings can be managed with conventional managing method.

Description

technical field [0001] The invention relates to the technical field of cuttage, in particular to a method for growing beech seedlings by cutting with high efficiency. Background technique [0002] Beech is one of the most important and precious hard broad-leaved tree species in the hills and plains of the middle and lower reaches of the Yangtze River. Beech has strong adaptability, beautiful tree shape, early autumn leaf color change period, long ornamental period, beautiful color, smoke-resistant and air-purifying, drought-resistant and barren, and less pests and diseases. It is an important autumn leaf landscape greening tree species in the Jiangnan area. Due to over-exploitation and utilization of resources, the amount of beech resources has decreased sharply and is in an endangered state. It has been listed as a second-level national key protected wild plant. [0003] Generally, beech trees are propagated by seeding, and the tree species required for reproduction need t...
