Embodiment 1

[0009] Choose the well-growing willow branches of the year, cut them to a length of 13-15cm, keep two leaves and two buds, cut off 3 / 4 of the leaves, and soak about 1 / 3cm of the base of the branches in cerium nitrate 50mg / L+GA 3 Treat in 20mg / L for 0.5h, insert the morphological lower end of the willow bark into the garden soil: bio-organic fertilizer = 3:1 matrix, the cutting depth is about 5 cm, the distance between cutting plants is 10×10cm; use automatic spraying regularly after cutting Spray water, spraying frequency is 15s every 10 minutes, spray 500 times thiophanate-methyl after 20 days, spray once every two weeks, spray 2 times in total, spray 3 / 4MS nutrient solution after two months, temperature Control at 25-27°C, humidity above 75%, cover with two layers of film, plant in field after four months, the survival rate is 80%.

Embodiment 2

[0011] Choose the well-growing willow branches of the year, cut them to a length of 13-15cm, keep two leaves and two buds, cut off 3 / 4 of the leaves, and soak about 1 / 3cm of the base of the branches in cerium nitrate 100mg / L+GA 3 Treat in 40mg / L for 0.5h, insert the morphological lower end of the willow bark into the garden soil: bio-organic fertilizer = 3:1 matrix, the cutting depth is about 5 cm, the distance between cutting plants is 10×10cm; after cutting, use automatic spraying regularly Spray water, spraying frequency is 15s every 10 minutes, spray 500 times thiophanate-methyl after 20 days, spray once every two weeks, spray 2 times in total, spray 3 / 4MS nutrient solution after two months, temperature The temperature is controlled at 25-27°C, the humidity is above 75%, covered with two layers of film, and planted in the field after four months, the survival rate is 81%.

Embodiment 3

[0013] Choose the well-growing willow branches of the year, cut them to a length of 13-15cm, keep two leaves and two buds, cut off 3 / 4 of the leaves, and soak about 1 / 3cm of the base of the branches in 80mg / L+GA of cerium nitrate 3 Treat in 40mg / L for 0.5h, insert the morphological lower end of the willow bark into the garden soil: bio-organic fertilizer = 3:1 matrix, the cutting depth is about 5 cm, the distance between cutting plants is 10×10cm; after cutting, use automatic spraying regularly Spray water, spraying frequency is 15s every 10 minutes, spray 500 times thiophanate-methyl after 20 days, spray once every two weeks, spray 2 times in total, spray 3 / 4MS nutrient solution after two months, temperature The temperature is controlled at 25-27°C, the humidity is above 75%, covered with two layers of film, and planted in the field after four months, the survival rate is 83%.

Abstract

The invention discloses a periploca sepium cuttage method. The periploca sepium cuttage method includes collecting and treating cutting slips, preparing a seedbed and a matrix, cutting and managing after cutting. By the periploca sepium cuttage method, the rooting percentage is high, hereditary changes are small, management and massive cultivation are facilitated, and basis is created for utilization of resources of periploca sepium.

Description

technical field [0001] The invention relates to the cutting culture of willow willow and belongs to the technical field of plant cultivation. Background technique [0002] bar willow, Periploca sepiumBge , shrubs, romoco, also known as goat's milk, acanthus bark, croissant, sheep peach, etc. Its characteristics are positive, cold resistance, drought resistance, barren resistance, light-loving, shade-tolerant, and strong adaptability to soil. The root system is deeply distributed and often clustered. Mainly distributed in Northwest, Northeast, North China and Henan, Sichuan, Jiangsu and other provinces. With wide adaptability, it is an excellent tree species for sand fixation and water and soil conservation. Root bark into traditional Chinese medicine. The stems and branches are used as Mongolian medicine. The stem bark and root bark contain more than ten kinds of glycoside compounds. The known structures include the cardiac glycosides saponin, saponins K, H, E, α-amyred...
