New technology of inducing clustered shoots from parispolyphylla rhizome for rapid vegetative propagation

Abstract

The invention provides a new technology of inducing clustered shoots from parispolyphylla rhizome for rapid vegetative propagation. The new technology comprises: selecting a parispolyphylla rhizome to keep in reserve, drying in air for 3-7 days, making incisions on the back of the rhizome by using a cutter, immersing the incisions in an ABT rooting powder solution with a concentration of 10-30 ppm fro 2-10 h, disinfecting the incisions by plant ash, coating the parispolyphylla rhizome with a mixture of plant ash and clean river sands, transplanting and cultivating the parispolyphylla rhizome according to strains, coating fine soil with thickness of 5 mm on the parispolyphylla rhizome. After planting the rhizome, cluster buds germinate from stock plants and grow for about one year, then each parispolyphylla stock plant generates about more than twenty plantlets each of which possesses buds, small rhizome and a fine root, and the plantlets are taken as parispolyphylla seedlings for transplanting, and after 3-4 years, parispolyphylla finished products are obtained. The new technology has high propagation coefficient, and the produced parispolyphylla plantlets have high survival rate and fast growth speed. Compared with parispolyphylla seed propagation, the new technology helps to shorten more than one third of growth time of a finished product; and compared with a parispolyphylla rhizome fragment propagation method, the new technology helps to improve propagation coefficient by 4-6 times, and helps to solve the raw material gap facing medicinal materials and industrial production.

Description

technical field [0001] The invention relates to the cultivation of medicinal plants, in particular to the high-efficiency asexual propagation and seedling cultivation technology of Huachonglou. Background technique [0002] The traditional Chinese medicine Huazhonglou is the rhizome of the perennial plant of the genus Paris in the family Liliaceae. The species recorded in the 2010 edition of Pharmacopoeia of the People's Republic of China are Paris polyphylla Smith var.chinensis (Franch.) Hara and P.polyphylla Smith var.yunnanensis (Franch.) Han.-Mazz. Huazhonglou is bitter in taste, cold in nature, slightly toxic, and has the functions of clearing away heat and detoxification, reducing swelling and relieving pain, cooling the liver and relieving convulsions. [0003] The traditional Chinese medicine Huazhonglou contains a variety of chemical components, and more than 50 compounds have been isolated and identified from it, mainly including C 27 steroidal saponins, C 21 Pr...

Problems solved by technology

In view of the current market prospect and resource status of Huazhonglou, it is urgent to carry out large-scale artificial planting of Huazhonglou. Due to the growth characteristics of Huazhonglou plants, artificial introduction and wild cultivation have been carried out in various places. However, most of them are local Sporadic planting in the area, its reproduction is a technical problem, and the current supply of seedlings is far from meeting the requirements of artificial cultivation of Huazhonglou. Therefore, it is necessary to use scientific and reasonable methods on the basis of fully understanding and mastering the biological characteristics of Huazhonglou. Research on the rapid propagation of Huazhonglou by using the method to promote the increase of the reproduction coefficient, shorten the biological lifespan, improve its quality, and improve the effective way for the large-scale growth of Huazhonglou medicinal materials

[0006] Although there are also methods such as adopting rhizome cuttings for asexual reproduction and seedling breeding in the current technology, there are many problems such as low reproduction coefficient, slow growth, and difficulty in large-scale promotion.
