Problems solved by technology

[0005] At present, there is no systematic research on the cultivation method of rosemary in the northern region to survive the winter and prevent cold. Therefore, it is of great significance to explore the method of cultivation in protected areas and the method of harvesting stems and leaves separately for the efficient and sustainable use of rosemary resources.

Embodiment 1

[0034] Embodiment 1, rosemary cold-proof cultivation method

[0035] 1. In 2010, in the Beijing area (39"26' to 41"03' north latitude, 115"25' to 117"30' east longitude), on November 1 (the average ground temperature in the 5 cm plow layer soil was 5°C, and the nighttime temperature was lower than 0 degrees Celsius, specifically -5 degrees Celsius, the surface soil freezes at night and disappears day by day, and the water can seep from the soil. The time is before the beginning of winter, that is, from the end of October to the beginning of November;) Fill the rosemary germplasm garden with enough water at one time ( 50m 3 water / acre), then set up a plastic shed, and spread straw curtains (Tianjin Jixian Grass Products Storage Company, CL1001) on the outer surface of the plastic shed, while ensuring manual care. In winter, if the temperature rises during the day (the temperature inside the shed reaches 25 degrees Celsius) or When the sun is sufficient, open the curtain in tim...

Embodiment 2

[0039] Embodiment 2, preparation and antibacterial activity detection of rosemary water extract

[0040] One, the preparation of rosemary water extract

[0041] On June 25, 2011, rosemary stems and leaves were harvested, dried in the shade to obtain stems and leaves, and steam distillation was used to extract essential oils, as follows: using a Clevenger type extraction device to extract rosemary by steam distillation Essential oils, as follows:

[0042] Dry the stems and leaves of the picked rosemary and crush them, weigh 100g of rosemary dry leaves and 100g of rosemary stems respectively, put them in a 2000ml round bottom flask, add 1000ml of distilled water to submerge the plant materials, and heat at a constant temperature of 180°C , Start timing after the first drop of essential oil drips out, and end the distillation after boiling for 2 hours. After stopping the heating, let it stand for 20 minutes. After the oil and water are separated, take the upper liquid in the oi...

Abstract

The invnetion discloses a method for cultivating rosemary. The method provided by the invention comprises the following steps of: 1), irrigating the rosemary from the end of October to the beginning of November in the north area, at the same time, erecting a plastic shelter, and covering coverings on the outer surface of the plastic shelter; 2), removing the coverings treated in the step 1) at the end of February in the next year; and 3), removing the plastic shelter treated in the step 2) at the end of March in the next year and irrigating the rosemary. Experimental results show that the method disclosed by the invention performs cold-proof cultivation in Beijing, and avoids the cultivation difficulty in the north area; the bacteriostatic activity of an essential oil extracted from the cultivated rosemary is high, so that the essential oil has inhibition effects on escherichia coli, staphylococcus aureus, bacillus subtilis and proteus.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for cultivating rosemary. Background technique [0002] Rosemary (Rosmarinus officinalis L.) is a perennial evergreen subshrub of Labiatae, native to the Mediterranean region, mainly distributed in France, Spain, Turkey and Italy. Introduced to my country by the Beijing Botanical Garden of the Institute of Botany, Chinese Academy of Sciences in 1981, it is now widely introduced as a raw material and garden ornamental plant in various provinces across the country. Among them, Guizhou, Yunnan, Guangxi, Hainan and other places have suitable climates, large cultivation areas, and a production scale. . [0003] The main constituents of rosemary essential oil are monoterpenes and their derivatives, including α-pinene, 1,8-cineole, camphor, camphene, and borneol (Pintore et al., 2002). According to ISO standards, there are two chemotypes of rosemary essential oil, Tunisian and Mor...
