Floating seedling culture method for Salvia miltiorrhiza

Abstract

The invention relates to a floating seedling culture method for Salvia miltiorrhiza. The method has the advantages that Salvia miltiorrhiza seedling culture time is shortened, the Salvia miltiorrhizaseedling culture cycle is shortened, annual circulating Salvia miltiorrhiza seedling culture can be achieved, and influence on local soil environments can be avoided; the germination rate and overwinter survival rate of Salvia miltiorrhiza seeds are increased effectively; meanwhile, the root system number of each seedling cultured by the method is increased evidently; the Salvia miltiorrhiza seedsare uniform in germination and stable in root system growth.

Description

technical field [0001] The invention belongs to the technical field of salvia miltiorrhiza cultivation, and in particular relates to a method for floating seedlings of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza, also known as red ginseng, purple salvia miltiorrhiza, red root, etc., has many functions such as promoting blood circulation and regulating menstruation, dispelling blood stasis and relieving pain, cooling blood and eliminating carbuncle, clearing heart and annoyance, nourishing blood and calming the nerves. In the prior art, the planting of Salvia miltiorrhiza is generally planted in August-September of each year, and the seedlings are transplanted around Qingming next year. At the same time, the requirements for the soil and environment in the planting area are relatively high. After the Salvia miltiorrhiza seedlings were cultivated once in the same year, In the second year, a large amount of soil nutrients are lost, which often cannot ...

Problems solved by technology

In the prior art, the planting of Salvia miltiorrhiza is generally planted in August-September of each year, and the seedlings are transplanted around Qingming next year. At the same time, the requirements for the soil and environment in the planting area are relatively high. After the Salvia miltiorrhiza seedlings were cultivated once in the same year, In the second year, a large amount of soil nutrients are lost, which often cannot be used as a cultivation environment for salvia miltiorrhiza seedlings again, resulting in the loss of soil environment nutrients and poor land. At the same time, the germination rate and resistance of salvia miltiorrhiza seedlings cultivated by traditional techniques are relatively low. low survival rate

[0003] The patent with publication number CN107950332A discloses a planting method of Salvia miltiorrhiza, which directly excavates planting holes in the soil ground to form a seedbed. While realizing the planting of Salvia miltiorrhiza, it will cause damage to the local soil structure. At the same time, after planting Salvia miltiorrhiza once , the local soil nutrient loss is serious, and repeated planting cannot be realized

[0004] The patent with the publication number CN108040785A discloses an ecological planting method of red salvia miltiorrhiza. Before planting red salvia miltiorrhiza, it is necessary to improve the physical and chemical properties of the soil and kill soil pests in advance. The eutrophication of the land environment or excessive microbial impoverishment is not suitable for the self-circulation purification and long-term use of the soil environment

[0005] The patent with the publication number CN107711386A discloses a method of planting Salvia miltiorrhiza that is beneficial to the growth of Salvia miltiorrhiza. Before planting Salvia miltiorrhiza in soil, it needs to be soaked in nutrient solution in advance, which takes a long time and increases the planting cost. Parameters such as soaking time need to be tested in advance, which is costly and time-consuming
