Embodiment 1
[0011] Embodiment 1 (take the spring propagation of Lysimachia congestiflora as an example with the ground cover plant Ju Hua Guolu Huang):
[0012] 1. Moderately level the breeding site and water it adequately.
[0013] 2. Arrange the stolon mother plants of Juhuaguoluhuang to be propagated in an overlapping manner in the same direction, so that the nodes of each stolon are aligned sequentially as much as possible, and then cut into single-stem segments with a length of 3-5cm in batches.
[0014] 3. Cut off the leaves on one side of the single stem section and keep the leaves on the other side.
[0015] 4. Evenly sow the single-node stem section on the breeding ground, cover about 5mm of nutrient soil, and water appropriately.
[0016] 5. Cover the breeding site with a transparent plastic film to maintain the humidity on the soil surface.
[0017] 6. Remove the plastic film when the new shoots produce 1-2 pairs of leaves (after 10-15 days), and manage them normally until th...
Embodiment 2
[0018] Embodiment 2: (taking the summer propagation of Lysimachia christinae as an example):
[0019] 1. Moderately level the breeding site and water it adequately.
[0020] 2. Overlap and arrange the mother plants of the stolons to be propagated in the same direction, so that the nodes of each stolon are aligned as much as possible, and then cut into single-stem segments with a length of 3-5cm in batches.
[0021] 3. Cut off the leaves on one side of the single stem section and keep the leaves on the other side.
[0022] 4. Evenly sow the single-node stem section on the breeding ground, cover about 5mm of nutrient soil, and water appropriately.
[0023] 5. Regularly and quantitatively spray the breeding site to maintain the humidity of the soil surface.
[0024] 6. When the new shoots produce 1-2 pairs of leaves (after 10-15 days), they can be watered and managed normally until the plants survive.

Abstract
The invention provides an efficient propagation method for stolon-type landscape ground cover plants (single-section stem-segment broadcasting). The method is concretely based on the characteristic that stem nodes of landscape plants can produce adventitious roots and lateral buds and utilizes the characteristic to effectively improve propagation efficiency thereof. The method comprises the following steps: (1) moderately leveling and sufficiently watering a propagation site; (2) putting to-be-propagated stolon maternal plants in order, aligning nodes of every stolon in turn to the greatest extent and then cutting the stolons in batches into stem segments having a singe node; (3) moderately cutting off leaves on single-node stem-segment nodes; (4) uniformly broadcasting single-node stem segments on the propagation site, covering the single-node stem segments with soil about 5 mm thick and moderately watering; and (5) performing spray irrigation quantificationally at regular time or covering with plastic film to keep soil-surface humidity and promote the growth of sprouts of the broadcast stem segments and performing normal management when the sprouts produce 1 to 2 leaves. The method has the advantages of saving a great amount of manpower and money and significantly improving the propagation efficiency of stolon-type landscape ground cover plants, along with high propagation coefficient.
Description
technical field [0001] The invention relates to a high-efficiency propagation method of stolon-like garden ground cover plants - sowing of single stem segments, belonging to the field of forestry biotechnology. Background technique [0002] Garden ground cover plants refer to those plants that are dense and low, and can be used to replace lawns to cover the ground, prevent soil erosion, absorb dust, purify air, reduce noise, eliminate pollution, and have certain ornamental and economic value after simple management. plant. Garden ground cover plants occupy a very important part in urban greening, and their propagation methods mainly adopt branching and cuttings, which require a lot of manpower and time, and the reproduction coefficient is relatively limited. However, for stolon-like garden ground cover plants, the propagation coefficient of cuttings and ramets is not optimal, because stolons generally have the characteristic of producing adventitious roots and lateral buds ...
