Embodiment

[0020] 1. In mid-May of that year, it was implemented in Jiangsu Sunshine Ecological Agriculture and Forestry Company. Cut the tender branches of the golden leaf elm as cuttings, each branch is 12cm long, and 2 leaves are left on the top.

[0021] 2. Immerse the lower end of the cuttings in NAA500ppm solution for 10 seconds, then take it out.

[0022] 3. The cutting substrate vermiculite: perlite: peat soil: = 1:1:1, mix evenly, the thickness of the slotting bed is 30cm, the facility is a small shed built in an all-weather greenhouse, and the small shed is covered with a layer of non-woven fabric.

[0023] 4. Insert the cuttings vertically into the mixed substrate 5cm, the row spacing of the plants is 5×5cm, pour water thoroughly after inserting, and spray 1000 times of carbendazim.

[0024] 5. The temperature in the shed is 25~35℃, and the relative air humidity is 70~90%. Pay attention to ventilation in the afternoon, and spray water on the non-woven fabric to cool down. Su...

Abstract

The tender branch planting method for goldleaf elm includes the following steps: cutting tender branch in 8-15 cm length as cutting wood in May to September, inserting the lower end of the cutting wood with naphthylacetic acid solution in 450-550 ppm concentration for 8-12 sec, planting into medium comprising vermiculite, perlite and turfy soil in the weight ratio of 1 to 0.8-1.2 to 0.8-1.2 inside an arched shed in an all-weather greenhouse, and maintaining the temperature inside the shed at 25-35deg.c and air humidity of 70-90 % for the cutting wood to grow callus in one week, root in 15 days. The said process has high planting survival rate.

Description

technical field [0001] The invention relates to a garden plant propagation method. In particular, it relates to a method for cutting young twigs of elm jinye. Background technique [0002] Golden-leaf elm is a newly discovered garden plant variety with high ornamental value and wide garden use in recent years. Its propagation usually adopts the method of white elm branches grafting golden leaf elm, which is small in number, low in reproduction coefficient, time-consuming, labor-intensive, expensive, and cannot meet the market demand for golden leaf elm. Golden leaf elm belongs to the tree species that cuttings are extremely difficult to take root (Gao Xinyi, "Plant Vegetative Propagation Technology"). There is no report on the cutting propagation technology of Ulmus jinye twigs at home and abroad. Contents of the invention [0003] The objective of the present invention aims at overcoming above-mentioned weak point, provides a kind of cutting propagation method of Ulmus...
