Problems solved by technology

Due to the slow growth and development of Diwu, low yield, and blind excavation, wild resources cannot meet the needs of the development of Chinese patent medicines. Under natural conditions, each plant has only 1-2 leaves, and the rhizomes of Diwu have few sprouts. Generally only rely on terminal bud germination and growth to accumulate biological yield

Embodiment 1

[0014] Treatment method: From June 8th to November 15th, 2007, the rhizomes of wild Aconiti officinalis collected from Tonggubao, Changyang County, Hubei Province were rinsed under tap water, and different concentrations of 6-benzyl were set according to Table 1. After soaking aminopurine (6-BA) for 24 hours, rinse it with tap water for 3 to 4 times, place it in a plastic box in yellow sand that has been sterilized by high temperature (according to the conventional sterilization method, that is, sterilize under high-pressure steam at 100°C for 20 hours), and cover it with multiple layers. Moisturize gauze. Then, germinate at 4°C (constant temperature day and night), 8°C-16°C (16°C during the day and 8°C at night in an artificial climate box) and 20°C (constant temperature day and night) as designed in Table 1, and add water in an appropriate amount every day. After one week, the terminal buds and lateral buds of the treated rhizomes of the Radix radix root have all germinated,...

Abstract

The invention relates to a method to break the dormancy of Diwu rhizomes, belonging to the technical field of agricultural plant cultivation. Diwu is also called Anemone flaccida Fr.Schmidt, which is a wild Chinese herbal medicine plant. The invention solves the problem that wild Diwu has short growth cycle, and small biomass and propagation coefficient. The invention provides an effective methodto break the dormancy of Diwu rhizomes, which is characterized in that: in each year, from the first ten days of June to the middle ten days of November, the Diwu rhizomes are soaked in 6-benzylaminopurine having the concentration of 1-20mg / L for 20 hours to 24 hours; then the Diwu rhizomes are washed by running water for three or four times, put in a plastic box equipped with yellow sand substrate, and cultivated under the temperature ranging from 4 DEG C to 20 DEG C; finally the Diwu rhizomes are transplanted under artificial light or natural light. The method has an advantage that, the invention provides technical support to the improvement of Diwu biological yield, off-season culture and the conversion from wild to artificial.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant cultivation, and in particular relates to a method for relieving dormancy of rhizomes of A. radix. Background technique [0002] Diwu, scientific name Anemone flaccida Fr.Schmidt, Ranunculaceae Anemone (Anemone L.), perennial herb, dried rhizomes can be used as medicine, mainly distributed in the provinces of the middle and lower reaches of the Yangtze River, growing at altitudes of 1500-3000m The damp place under the hillside forest. In the Hubei region of China, seedlings emerge in mid-March every year, and the aboveground part gradually dies in late May, and then enters a dormant period. The growth period is short, the growth is slow, the biological yield is small, and the seed fertility is low. There is no report on artificial cultivation. [0003] Pharmacological studies have found that the active ingredients of Diwu - triterpene saponins, mainly have heat-clearing and detoxifying...
