Abstract

The invention relates to a tree cutting propagation technology, in particular to a hard branch greenhouse cutting method for straight-stem ulmus pumila. The hard branch greenhouse cutting method comprises the following steps of preparing a substrate; conducting filling, cutting and bed placing; selecting and intercepting cutting slips; conducting cutting slip treatment and cuttage; and conductinggreenhouse management after cuttage, specifically, spraying water, controlling temperature, preventing and treating diseases and insect pests, applying fertilizer, hardening seedlings and taking the seedlings out of a garden. When the method is used for cuttage, the survival rate of the straight-stem ulmus pumila can reach 90% or above, the death rate of the straight-stem ulmus pumila is only lessthan 10%, and large-scale propagation of the straight-stem ulmus pumila is effectively achieved.

Description

technical field [0001] The invention relates to a tree cutting propagation technology, in particular to a method for cutting hard branches of straight elm in a greenhouse. Background technique [0002] The straight elm is a variety selected from the white elm. Deciduous tree with spherical crown. Branchlets glabrous or hairy, yellowish gray, light brownish gray or gray, sparsely light brownish yellow or yellow, with scattered lenticels. The leaves are elliptic-ovate or elliptic-lanceolate, the apex is pointed or acuminate, the base is wedge-shaped on one side, and the other side is nearly round, the leaf margin is irregularly serrated or single-toothed, glabrous or the veins are slightly tufted pubescent, the texture of the old leaves thicker. Flowers in clusters. The wing fruit is nearly round, yellow-white when ripe, glabrous. Flowers open from March to April before leaves; fruit ripens from April to May. [0003] The characteristics of straight elm are: [0004] 1....
