Rhizoma paridis seedling raising method

Abstract

The invention relates to the technical field of Chinese medicinal material seedling raising, in particular to a rhizoma paridis seedling raising method. The method comprises the following steps: (1) mature and plump, healthy and mildew-free and non-injurious rhizoma paridis seeds are selected, the episperm is washed away, the seeds are immersed in a seed soaking solution for ultrasonic treatment,and the seeds are then placed in a ventilation place and are dried and are preserved for 60 to 80 days under a temperature of 1 to 3 DEG C; (2) organic matter-rich soft soil is selected as a nursery,decomposed manure and a biological fungicide are applied per mu, and the land is leveled; (3) the rhizoma paridis seeds are spread on a seedbed and covered with hay of 1 cm to 2 cm, after seedling emergence happens to the rhizoma paridis seed at the first time, a foliar fertilizer is applied after the rhizoma paridis leaf is flattened and the biological fungicide is applied; after second-time seedling emergence in the next year, a compound fertilizer is applied for one time each two months after the rhizoma paridis leaf is flattened; and transplanting is carried out after third-time seedling emergence. The rhizoma paridis seedling raising method disclosed in the invention has the advantages that the dormancy period of the seeds is improved, the post-ripening time of the seeds is shortened,the seedling emergence and cultivation period of the seeds is quickened, and the survival rate of the seeds is improved.

Description

technical field [0001] The invention relates to the technical field of growing seedlings of traditional Chinese medicinal materials, in particular to a method for growing seedlings of Chinese herbal medicines. Background technique [0002] Chonglou is a perennial herb belonging to Liliaceae. It is mainly distributed in Yunnan, Guangxi, Guizhou, Sichuan and other places in my country. The surface of Chonglou is yellow-brown or gray-brown, and the shedding part of the skin is white. The rhizome is used as medicine. It is slightly cold in nature, bitter in taste, and slightly poisonous. It is a traditional Chinese medicine variety in China. Efficacy, used for carbuncle, sore throat, snake bites, bruises, convulsions and convulsions, etc. It is one of the main raw materials of Yunnan Baiyao, Gongxuening Capsules, and antiviral granules.

Problems solved by technology

[0003] The seeds of Chonglou have a dormant phenomenon. During the germination process of the seeds, they need to go through two stages of morphological post-ripening and physiological post-ripening. Under natural conditions, it takes 18-22 months to emerge, and the emergence rate is relatively low, and the seedling rate is even higher. is less than 1%

At present, the artificial cultivation of Chonglou mainly contains two methods: seed breeding and rhizome cutting and segment raising. Although the rhizome cutting and section raising has a short seedling cycle, the cost of seedlings is high, which is not conducive to the large-scale artificial cultivation of Chonglou; although the cost of seed raising is low, But the germination rate is quite low
