Embodiment 1

[0022] A method for field propagation of Salvia miltiorrhiza, specifically comprising the following steps:

[0023] Step 1, applying agricultural base fertilizer in the planting field, wherein the application rate of agricultural base fertilizer is 2000kg / mu;

[0024] Step 2. The rotary tiller plows the land deeply. The depth of deep plowing is 20-50cm, and the field is formed into a furrow with a width of 1.2 meters. The length is determined according to the specific length of the field. Each ground hole passes through the plastic film, the row spacing of adjacent rows of ground holes is 30cm, the hole spacing of adjacent ground holes in each row is 15cm, and the depth of each ground hole is 6cm;

[0025] Step 3, select freshly excavated Salvia miltiorrhiza, choose the root bar of Salvia miltiorrhiza that is straight, disease-free, ruddy in color and 0.3-0.5cm in diameter as the seed root, and set aside;

[0026] Step 4. When planting, manually break the seed root into 4-5cm...

Embodiment 2

[0030] A method for field propagation of Salvia miltiorrhiza, specifically comprising the following steps:

[0031] Step 1, apply agricultural base fertilizer in the planting field, wherein the application rate of agricultural base fertilizer is 2000kg / mu, and apply the commercially available fungicide carbendazim to the field prone to bacterial contamination, and the application rate of carbendazim is 10kg / acre;

[0032] Step 2. The rotary tiller plows the land deeply, and the field is formed into a 1.2-meter-wide furrow. The length is determined according to the specific length of the field. The surface of the furrow is covered with plastic film, and then holes are drilled so that each ground hole passes through the plastic film. The row spacing of adjacent rows of ground holes is 30cm, the hole spacing of adjacent ground holes in each row is 15cm, and the depth of each ground hole is 6cm;

[0033] Step 3, select freshly excavated Salvia miltiorrhiza, choose the root bar of ...

Abstract

The invention discloses a field breeding method for salviae miltiorrhizae. The method comprises the following steps of application of an agricultural base fertilizer; deep tillage of soil; covering with a plastic film; punching; root segment planting; watering; and normal field management until ripening of salviae miltiorrhizae. According to the method, the problem of a long growth period of the salviae miltiorrhizae is solved by adopting vegetative propagation of root segments and a laminating technology; the three-year term is shortened into 12 months; the soil moisture is conserved; weed growth is inhibited; diseases, such as root-knot nematode and root rot, are reduced; the germination rate is improved; the salviae miltiorrhizae yield per mu is greatly improved; the average yield per mu can reach 480g dry product; and therefore, a good method is provided for implementation of agricultural green and pollution-free production.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a field propagation method of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza is a perennial herb of the Lamiaceae genus Salvia. Its roots and rhizomes are used as medicine. It was first recorded in the "Shen Nong's Materia Medica" in the Eastern Han Dynasty and listed as a top grade. It has the effect of promoting blood circulation and removing blood stasis. Both are distributed and cultivated. Field propagation of Salvia miltiorrhiza is usually done by live-seeding seedlings. The emergence of seedlings is uneven. After seedlings are transplanted and grown in the field until they are harvested, it takes three years. The yield is low and there are many diseases and insect pests. [0003] Asexual propagation technology can solve the shortcoming of long seed growth cycle. Asexual propagation technology includes root cuttings, lea...
