Rosemary cutting and breeding method

Abstract

The invention discloses a rosemary cutting and breeding method, which comprises the following steps of (1) preparing a cutting medium: selecting rice chaff ashes as a matrix to cover a film; (2) preparing for cutting slips: selecting rosemary branches; (3) the cutting of cutting slips: soaking cutting slips in the 100-200 mg / L NAA aqueous solution for 10 minutes, then inserting the cutting slips in rice chaff ashes and covering a film on the cutting slips; (4) cultivating shoots. According to the invention, the above medium is alkalescent, and the temperature of the medium is improved. Meanwhile, the black medium facilitates the growth of roots, shortens the rejuvenation period of vitro plants, reduces the damage to roots during the seedling lifting process, and shortens the rejuvenation period. Through covering the film, the poor water retaining capacity of rice chaff ashes is made up, and the ground temperature is ensured at the same time. moreover, through the treatment in the NAA aqueous solution, the growth and survival rate of the roots of cutting slips is improved.

Description

technical field [0001] The invention belongs to the technical field of horticultural plant cultivation and propagation, and in particular relates to a cutting propagation method of rosemary. Background technique [0002] Rosemary (Rosmarinus officinalis) is a perennial evergreen subshrub of the Lamiaceae Rosmarinus. 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 meter high, and the highest can reach 2 meters. 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 curl towards the back of the leaves. The epidermis of the stem is hard, woody brown; its root system is relatively developed, and the main root can be buried 20-30cm into the soil; the racemes are axillary, the flowers are small, the corolla is lip-shaped, and the length is about 1.5cm; the f...

Problems solved by technology

[0003] The growth of rosemary seeds is poor, the germination ability of the seeds is low, and the germination rate of conventional seedlings is not high, usually around 30%, and the germination time is as long as 25 days or more

Due to the relatively low reproduction coefficient of sowing seedlings, it cannot meet the needs of the market
