Rosa damascena rapid breeding method

Abstract

The invention relates to a rapid breeding method of Damask rose, which relates to the field of plant breeding, in particular to a rapid breeding method of Damask rose. Aiming at the shortcomings of existing breeding, a method for rapid breeding of rose Damascena with low requirement for cuttings, saving branches and high survival rate is provided. In this method, river sand is selected as the substrate, and 2 cm lignified shoots are selected for cuttings, and are grown in a greenhouse through a series of treatments. The present invention uses 2 cm cuttings for breeding, which greatly saves the amount of cuttings. Under this condition, the emergence rate of roses is high, the survival rate of transplanting is high, and the economic benefits are remarkable; river sand is used to replace the nutrient matrix, which has good water permeability and moisture retention, and avoids the growth of the matrix. More water storage is prone to the problem of germs. After the rooting of the transplanted seedlings, the root system is easy to develop directly through the river sand and grow in the field soil, which is conducive to the maturity and aging of the root system and improves the survival rate of transplanting.

Description

technical field [0001] The invention relates to the field of plant breeding, in particular to a method for rapid breeding of Damask roses. Background technique [0002] Rose is one of the famous flowers in the world, known as the "Queen of Flowers", and was honored as the "Flower of the Goddess" in ancient China. Rose oil extracted from roses is known as "liquid gold". In the terminal market of distilled rose essential oil, the value of 1 kg of rose essential oil is approximately equal to 1.25 kg of gold. [0003] Our country introduced Damascus rose from Kazanlak, Bulgaria in 1984 and bred it domestically. It was later named Qinwei No. 1 Damascus rose. It is internationally recognized as the best rose variety for oil. Rose cutting seedling breeding technology is generally used to transplant seedlings by dividing roots from strong mother plants. This method is costly, and only about 1,000 seedlings can be produced per mu. The price is high, and it can only be used in winter...

Problems solved by technology

[0003] Our country introduced Damascus rose from Kazanlak, Bulgaria in 1984 and bred it domestically. It was later named Qinwei No. 1 Damascus rose. It is internationally recognized as the best rose variety for oil. Rose cutting seedling breeding technology is generally used to transplant seedlings by dividing roots from strong mother plants. This method is costly, and only about 1,000 seedlings can be produced per mu. The price is high, and it can only be used in winter. Planting, the survival rate is only about 80%, which is not conducive to the rapid expansion of the planting area in a large area, thereby limiting the rapid development of the oil rose industry

Although there are domestic precedents for cuttings to cultivate Damascus rose seedlings, the traditional method is adopted. Generally, the cuttings are required to be 10-15cm long, and the cuttings are required to have double buds and at least 3 axillary buds. The selection is harsh. At the same time, mixed substrates are used with nutrient pots, high temperature and high humidity, easy to grow bacteria, and the root system is restricted in the nutrient pots. very high
