Growth matrix and method for vegetative propagation of medicinal plant paris polyphylla by employing growth matrix

Abstract

The invention discloses a growth matrix and a method for vegetative propagation of a medicinal plant paris polyphylla by employing the growth matrix. The growth matrix is prepared from the following ingredients in parts by weight: 120-160 parts of garden soil, 30-50 parts of high-calcium fly ash, 20-30 parts of laterite, 10-20 parts of attapulgite clay, 8-12 parts of sodium humate, 2-4 parts of water-soluble zinc salt, 1-3 parts of magnesium salt,1-3 parts of water-soluble sylvite, 1.5-2.5 parts of an water-soluble ammonium salt, 30-50 parts of water and 6-10 parts of a folium sennae extract. The preparation method of the folium sennae extract comprises the steps of carrying out heat reflux extraction on folium sennae by using an ethanol solution of which the volume percent is 70-90% for 2-4 times, mixing extract solutions, carrying out vacuum concentration and then carrying out spray drying to obtain the folium sennae extract. The growth matrix is stable and efficient, the survival rate is high, the basic total saponin content of seedlings is obviously improved, and growth of the medicinal paris polyphylla with abundant total saponin is facilitated.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a growth substrate and a method for vegetatively propagating medicinal plant polyphylla with it. Background technique [0002] Paris L. is a general term for plants of the genus Paris L. in the family Liliaceae. It is a perennial herb that mostly grows in damp places under forests, valleys or grass at an altitude of 600-3600m. It is mainly distributed in Yunnan, Sichuan and other places. Chonglou is bitter in taste, slightly cold in nature, and slightly poisonous. Its rhizomes are used as medicine, and its active ingredient is total saponins. It is often used in the treatment of sores, swollen toxins, snake bites, mastitis, tonsillitis, convulsions and convulsions in children, and is an important raw material for Chinese patent medicines such as Duoming Dan, Total Saponin Tablets, Yunnan Baiyao, Gongxuening and other preparations .

Problems solved by technology

[0003] Since the 1980s, scientific research workers have carried out research on the sexual and asexual reproduction of Chonglou, and the physiological characteristics of "secondary dormancy" (from October of the first year to around May of the third year) determine the effectiveness of the double dormancy. Due to the limitations of sexual reproduction, under natural conditions, seedlings need two winters and one summer to emerge, and it takes 8-10 years from planting to harvest. In addition, the increasing demand for chrysanthemums in recent years has led to wild The predatory destruction of germplasm resources, therefore, the sexual reproduction of Chonglou can no longer meet the needs of the market
