Damask rose twig cutting seedling-raising method

Abstract

The invention discloses a damask rose twig cutting seedling-raising method which includes the steps: S1 performing laying and disinfecting of seedling beds; S2 performing preparation and disinfection of culture media and layout of plugs; S3 cutting semi-lignified twigs without diseases and insect pests on stock plants, performing water spraying and moisturizing on the cut semi-lignified twigs, cutting cuttings at shade places, and performing disinfection on the cut cuttings; S4 plunging deep holes in the culture media, treating the disinfected cuttings by the aid of rooting agents, performing cutting on the treated cuttings, lightly pushing sealing openings with fingers after cutting, and enabling the culture media and the cuttings to be closely connected; S5 performing reasonable atomizing and light supplement management after cutting. 2-3 bud joints are reserved on each cutting, the length of each cutting is about 8cm-10cm, 4 leaflets of the upper portion of each cutting are reserved, the position 5 millimeters away from the uppermost bud joint of each cutting is horizontally cut, the position 3-5 millimeters away from lowermost bud joint of each cutting is cut into a 45-degree inclined plane, and the cutting depth does not exceed 3cm. The method is rapid in rooting, high in transplanting survival rate, simple and easy to operate, and a seedling-raising period can be greatly shortened.

Description

technical field [0001] The invention relates to the field of seedling propagation, in particular to a method for growing seedlings by cuttings of Damask rose twigs. Background technique [0002] Damascus rose (Rosa damascene Mill) is native to the west of Asia, also known as Turkic rose, is a famous aromatic oil plant of Rosaceae Rosaceae. Rose essential oil extracted from Damascus rose flowers has the functions of relieving stress, lightening scars, anti-allergic, whitening, regulating menstrual cycle, treating eczema, regulating and shrinking capillaries, etc. It is the best rose essential oil. Damask rose essential oil is of good quality and is very popular in the international market. The price per kilogram of essential oil is as high as 7,000-8,000 US dollars, which is 3-4 times that of rose essential oil in my country. [0003] In the 1980s, my country began to introduce and cultivate damascena roses, and now there are introductions all over the country. Cultivating r...

Problems solved by technology

[0004] The above two rose twig cutting propagation methods, one is that the regular watering method will cause the soil humidity around the cutting branches to fluctuate greatly, and the cutting branches absorb the water in the soil unevenly, some are dry and some are waterlogged, which will lead to a decrease in the rooting rate of the cutting branches. Low, the survival rate of cutting seedlings is low

The second is that the cuttings are inserted into the substrate of the floating seedling tray to control the water fluctuation by adjusting the liquid level. The operation procedures are too many and complicated, and it is difficult to master. The seedling raising cycle is long, and it is not suitable for industrial seedling raising technical requirements.
