Problems solved by technology

Due to the relatively low reproduction coefficient of sowing seedlings, it cannot meet the needs of the market
Rosemary has many flowers in production, and the stem tip needs to be removed to increase the amount of side branches, but the survival rate of the removed stem tip cuttings is low

Embodiment 1

[0026] In May 2010, 2-year-old rosemary was cut from the Suzhou Chunhui Herb Garden Base, and healthy stem tips with a stem diameter of 0.5-1 cm and axillary buds were selected as the source of cuttings. Cut the tip of the stem into a small section of 5-6cm as cuttings, leave 1 node in each section, and leave 1-2cm below the node, cut into an oblique mouth, the slope is 30° from the horizontal plane, and 2-3cm is left on the node, and cut into a flat mouth. A mixed aqueous solution of NAA and IBA (total mass concentration 10 mg L -1 ) soaked for germination treatment, soaked for 24h.

[0027] The cutting matrix peat, perlite and vermiculite were mixed evenly according to the mass ratio of 1:1:1, the matrix was irrigated before the cutting, and the cutting environment was ensured to be moist during the test period. The cutting bed is covered with plastic film to moisturise. The day / night temperature of the substrate is controlled to be 20-25°C / 15-20°C through the geothermal l...

Embodiment 2

[0029] The cutting procedure is all carried out according to Example 1, the difference is that the cutting induction treatment is 10 mg L -1 Aqueous solution of IBA. After 20 days, the germination rate of rosemary shoots was 92.4%.

Embodiment 3

[0031] The cutting procedure is all carried out according to Example 1, the difference is that the cutting induction treatment is 10 mg L -1 Aqueous solution of NAA. After 20 days, the germination rate of rosemary shoots was 88.9%.

Abstract

The invention discloses a rosemary stem tip cutting propagation method, which comprises the following operation steps: 1) manufacturing cutting media, 2) cutting the rosemary stem tips, 3) inducing the rooting of cutting slips, 4) cutting the cutting slips, 5) managing the cutting slips before rooting, and 6) cultivating seedlings. According to the cutting propagation method for the rosemary disclosed by the invention, the stem tips of the rosemary are cutting slips, and every stem tip of the rosemary can become a seedling; compared with the efficiency of the existing seed propagation method,the efficiency of the rosemary stem tip cutting propagation method is increased by more than 30 times; and the cutting slips firstly root, and are then induced to sprout, the roots of the cutting slips are strong, the transplantation survival rate is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to a cutting propagation technology of rosemary, and belongs to the technical field of plant artificial propagation methods. Background technique [0002] Rosemary (Rosmarinus officinalis) is a perennial evergreen subshrub of the genus Rosemary of the Lamiaceae family. , grows well in dry, well-drained, sunny places. Rosemary is widely used in daily chemical, food processing and pharmaceutical industries. The plant is erect, the main stem is about 1 m high, and the highest can reach 2 m. The leaves are narrow and pointed, about 1 cm long, shaped like curved pine needles; dark green, bright above, white below, and the leaf margins are curled toward the back of the leaf. The stem epidermis is hard and woody brown; the root system is relatively developed, and the main root can be buried in the soil 20~30cm; the racemes, axillary, the flowers are small, the corolla lip-shaped, about 1.5cm long; the flowering period is from June to ...
