High-yield Cultivation Method of Salvia Miltiorrhiza

Abstract

The invention discloses non-flowering high-yield cultivation of radix salviae miltiorrhizae. Seminal roots are adopted as propagation materials, so that vegetative propagation of the radix salviae miltiorrhizae is realized, the purpose of no flowers and seeds of the radix salviae miltiorrhizae in the growth period is achieved, plant nutriments are concentrated in the roots, the yield of medicinal materials is greatly increased, and the quality of the medicinal materials is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of salvia miltiorrhiza cultivation, in particular to a high-yield cultivation method of salvia miltiorrhiza without flowers. Background technique

[0002] For a long time, Yaonong has used sexual reproduction to cultivate Salvia miltiorrhiza, which has caused severe species loss and poor disease resistance, especially root nematodes in the Yimeng mountainous area of ​​Shandong Province, which have seriously affected the quality and yield of medicinal materials.

[0003] In addition, the Danshen planted by the traditional seed propagation method will bloom like a brocade in May after planting. The flowering period of Danshen will last until August. The whole flowering period will consume a lot of nutrients, which will affect the quality and output of Danshen. Contents of the invention

[0004] Aiming at the above disadvantages, the present invention provides a high-yield cultivation method for salvia miltio...

Embodiment 1

[0014] A high-yield cultivation method for salvia miltiorrhiza without flowers, comprising the following steps:

[0015] (1) Reserving seeds In November of the first year, when the temperature is 2 degrees, start harvesting Salvia miltiorrhiza, and select the roots of Salvia miltiorrhiza that are healthy and free from diseases and insect pests as seed roots.

[0016] (2) Preservation of seed roots The harvested seed roots are stored in a cellar. During the entire storage period, the cellar temperature is 5 degrees, and the storage cellar is ventilated and dehumidified under the premise of ensuring the cellar temperature;

[0017] (3) At the beginning of February of the next year for seedling cultivation, divide the root cuttings before and after the beginning of spring to grow seedlings. Divide the seed roots into small sections of 5-6cm. Cover and control the temperature in the shed above 10 degrees. After 20 days, the roots will emerge.
