A kind of Jin Tiesuo hydroponic rapid rooting method

Abstract

A method for rapid rooting and seedling growth of Jintiesuo hydroponics, the method comprises selecting two-year-old Jintiesuo after all seeds have been harvested in the seed harvesting period, and taking its green leafy 5-8cm long stem section, and each stem section retains 3 For buds and 3 pairs of leaves, after carbendazim disinfection treatment, under the condition of artificial climate box, culture in hydroponic rooting culture solution, the hydroponic rooting culture solution is IBA solution with a concentration of 0.5-1ppm, and the culture conditions set in artificial climate box It is: ① temperature 22°C, humidity 60%, light intensity 15000lx, 16h; ② temperature 16°C, humidity 60%, light intensity 0lx, 8h. This method has the advantages of fast rooting, large root system, robustness, high seedling rate, and low cost, and solves the problems of poor emergence potential, long emergence period, and low seedling rate of Jintiesuo seedlings, and will provide a new way for the industry of Jintiesuo in the future. It provides technical support for rapid breeding.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant breeding, and in particular relates to a method for rapid rooting and seedling formation of Jin Tiesuo in hydroponics. Background technique [0002] Psammosilene tunicoides (Psammosilene tunicoides) is a single-species perennial herb of Caryophyllaceae. Jintiesuo has important medicinal value. Its dried roots are used as medicine in the folks. It has the functions of dispelling blood stasis, relieving pain, dispelling rheumatism, and reducing inflammation. , Jingulian Capsules, Baibaodan, Tongxuekang Capsules and other raw materials of Chinese patent medicines. The distribution area of ​​wild resources of Jintiesuo is narrow and the quantity is small, coupled with a large number of human excavation, the distribution of wild resources has decreased sharply, and it has been listed as a national second-class protected plant. In order to meet the demand of Jintiesuo medicinal materials marke...

AI Technical Summary

Problems solved by technology

However, the seed propagation of Jintiesuo mainly has the following problems: First, because the inflorescence of Jintiesuo is an infinite inflorescence, there are problems of different seed maturity periods, so that the maturity of each seed is inconsistent, and most people fail to do it during the harvesting of seeds. Harvested in stages, some of the seeds were shriveled, which reduced the quality and emergence rate of Jin Tiesuo seeds as a whole; second, the emergence of the seeds after sowing was poor, and the emergence period was as long as one month, and the emergence was irregular

The third is that Jintiesuo is a perennial plant, and the seeds are easy to fall off after maturity. Every year, seeds fall in the field to germinate naturally, resulting in an uncertain commodity life of Jintiesuo roots in the field.

There are also relatively many reports on the method of rooting and seedling growth through tissue culture of Jin Tiesuo, but there are also defects such as long cycle time and high cost.
