Embodiment 1

[0047] A method for branch propagation suitable for plateau lavender, comprising the following steps:

[0048] (1) Select slightly alkaline or neutral sandy soil, and the soil is deep, flat, and saline-free plots for site preparation, and apply base fertilizer. Apply 500kg of high-quality sheep manure, 15kg of phosphate fertilizer and 10kg of urea per mu as the base fertilizer, and turn over 15cm after applying the base fertilizer;

[0049] (2) French blue lavender plants are the breeding objects, remove diseased plants and old branches, and select 3 to 5-year-old strong seedlings with a plant height of 20-50 cm and ramets with bud eyes.

[0050] (3) Ridge the plots after the above-mentioned land preparation to form a furrow with a width of 70 cm. Ridge into a furrow to increase soil permeability, promote root growth and development, and facilitate irrigation and drainage; the above-mentioned selected lavender plant ramets are planted in the furrow, and the row spacing is 1m,...

Abstract

The invention provides a division propagation method suitable for plateau lavenders, and belongs to the technical field of lavender propagation. The propagation method comprises the following steps: applying a base fertilizer to a deep, smooth and saline-alkali-free soil block, ploughing, ridging, furrowing and carrying out soil preparation; planting healthy and disease-free lavender plants in furrows in a division manner, watering, topdressing, pruning, irrigating, weeding and carrying out disease field management; after the lavenders enter a full blooming period, harvesting the lavenders; and managing the lavenders before overwintering in the middle ten days and the last ten days of the November. According to the division propagation method, soil permeability is improved through ridgingand furrowing, growth and development of a root system are promoted, meanwhile, drainage and irrigation are facilitated, topdressing and irrigation are timely carried out to preserve soil moisture andincrease temperature, germination and new shoots of lavenders in the coming year are promoted to increase the flowering rate through multiple pruning, meanwhile, robust growth of the lavenders is promoted through long illumination time and strong sunlight in the plateau area, and the division propagation survival rate is improved. Moreover, seedlings obtained by the method disclosed by the invention bloom rapidly, plants grow robustly, flower shapes are full, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of lavender propagation, and in particular relates to a branch propagation method suitable for plateau lavender. Background technique [0002] Lavender (Lavandula angustifolia Mill) is a perennial herb of the genus Lavandula of the Lamiaceae family. It is native to areas with low rainfall such as the Mediterranean coast, Europe, and Oceania archipelago. It is widely planted in Britain, the United States, Japan and other countries. It has high ornamental value. [0003] At present, the market has a large demand for lavender, but the traditional lavender planting technology has low yield, which is not conducive to the large-scale promotion and planting of lavender. The current propagation methods of lavender are mainly seed propagation and cutting propagation. The germination rate of seed propagation is low and the growth cycle is long. For example, the Chinese patent application number CN 108235839 A provid...
