Abstract

The invention relates to a method for inducing rooting of hydroponic taraxacum kok-saghyz. According to the method, hormone with a certain concentration is added into an improved Hoagland nutrient solution to serve as a hydroponic nutrient solution, rootless seedlings are fixed to holes of a floating plate, so that plant bases can make full contact with the nutrient solution, and the biomass of the plant roots and leaves is remarkably improved after the seedlings are cultured for a period of time through the nutrient solution. The method for inducing rooting of the hydroponic taraxacum kok-saghyz is simple and easy to implement and low in cost. The taraxacum kok-saghyz plants obtained with the method are robust and grow well, a large number of new hairy roots are formed through induction, and an effective way is provided for rapid growth recovery of the taraxacum kok-saghyz plants after root extraction and improvement of the production efficiency of extracting synanthrin and natural rubber from the taraxacum kok-saghyz.

Description

technical field [0001] The invention relates to a method for inducing rooting of hydroponic rubber grass. Background technique [0002] Natural rubber is an important strategic material and industrial raw material. Rubber grass (Taraxacum kok-saghyz), also known as Russian dandelion (Rubber Dandelion), is a perennial herb of the genus Dandelion in the Compositae family. It is native to Kazakhstan and Xinjiang, China. Its roots can synthesize high-quality natural rubber and inulin. Rubber grass has the advantages of strong adaptability, wide adaptation area, short growth and harvest period, can be stored in the field, and can be rotated or intercropped, suitable for mechanized planting and harvesting, making it a new rubber-producing crop with great development prospects. [0003] Rubber grass is a self-incompatibility plant, with high seed heterozygosity and severe segregation of progeny traits. Propagation by seeds is not conducive to the preservation of excellent strains....
