Example Embodiment

[0026] Example 1:

[0027] The experiment was divided into an invention group and a control group. The invention group had a volume ratio of turf: vermiculite: garden soil = 2: 1:1 and mixed uniformly as the cutting substrate, and the control group had garden soil as the cutting substrate, and 50 pieces of 8 In a cm×8 cm plastic nutrient cup, 50 cuttings of Lavender angustifolia were treated in each group. Implemented in the solar greenhouse of Beijing Academy of Agriculture and Forestry Sciences. Select the semi-woody branches of the current year as cuttings, each cutting is 7-9 cm long, with two nodes, the lower part is cut obliquely at 45°, 0.3-0.5 cm from the node, and the upper part is cut flat, 0.3-0.5 cm from the node; Only the upper leaves of each cutting are retained.

[0028] Use 0.5% KMnO at the lower end of cuttings 0~3cm 4 Sterilize the solution for 1 to 2 minutes, wash with water, and then soak it in 1000ppm ABT rooting powder solution for 30 minutes. After taking ...

Example Embodiment

[0032] Example 2:

[0033] Implemented in the solar greenhouse of Beijing Academy of Agriculture and Forestry Sciences. Cut the semi-ligninized branches of broad-leaf lavender and Xinjiang lavender as cuttings, and cut 50 cuttings. Each cutting is 7-9 cm long, with two nodes, the lower part is cut obliquely at 45°, 0.3-0.5 cm away from the node, and the upper part is cut flat, 0.3-0.5 cm away from the node; each cutting only retains the upper leaf.

[0034] Use 0.5% KMnO at the lower end of cuttings 0~3cm 4 Disinfect the solution for 1 to 2 minutes, wash it with clean water, and then soak it in 1000ppm ABT rooting powder solution for 30 minutes before taking it out.

[0035] The cutting substrate is turf: vermiculite: garden soil = 2: 1: 1 volume ratio, mixed evenly, and put into 8 cm×8 cm plastic nutrition cup.

[0036] Insert a single plant and a cup of cuttings into the mixed substrate vertically at a cutting depth of 2 to 3 cm. After insertion, water it thoroughly and cover it ...

Abstract

The invention relates to a lavandula angustifolia Mill. cutting propagation method. The invention relates to a cutting propagation method adopting the annual plants of lavandula angustifolia Mill. as mother ears, aiming at the present problems of low setting percentage, long seed germination and raised seedling propagation time, low survival percentage and the like of lavandula angustifolia Mill. The method comprises the steps of cutting medium preparation, cutting selection, rooting agent treatment, cutting, cutting culture conditions, management after cutting, transplanting and land management, wherein the cutting medium is optimized and the cuttings are subjected to single-cup single-plant cutting. The method has the following beneficial effects that the rooting percentage of the cultured cutting seedlings reaches 91%; the root systems are flourishing; and the transplanting survival percentage reaches 100%. Compared with lavandula angustifolia Mill. tissue culture and rapid propagation methods, the method has the advantages of simpleness in operation, small amount of labor, high growth speed, high rooting percentage, high transplanting survival percentage, robust seedlings and the like and has higher popularization and application values and vast development prospect.

Description

technical field [0001] The invention relates to a lavender cutting propagation method, which belongs to the field of horticultural production. Background technique [0002] Lavender( Lavandula angustifolia Mill.), a perennial subshrub of Labiatae, is native to the Mediterranean region and the southern foothills of the Alps, and is distributed from Turkey, Canary Island, northern Africa, Spain to the Middle East. It is mainly cultivated in France, Bulgaria, Italy, the United Kingdom and other countries. At present, there are two famous lavender producing areas, located in Provence in southeastern France and Furano in Hokkaido, Japan. In my country, Xinjiang is the main planting base of lavender, and its planting area accounts for more than 95% of the country. Lavender is bright in color and rich in fragrance. It is one of the main natural spice plants. Because it is rich in essential oils and has good landscape effects, it is not only used in pharmaceutical, spice and cos...
