Problems solved by technology

Since the breeding cycle of Polygonatum seeds is more than 2 years, the size of the seedlings is uneven, which affects the transplanting and large-scale promotion of Polygonatum seedlings
In the current artificial cultivation, rhizome seedlings are mainly used, but this method has a low propagation coefficient, a large amount of seed rhizomes, high labor costs, and a large amount of medicinal rhizomes are wasted, which is not conducive to the large-scale promotion and cultivation of Polygonatum multiflora. The Bottleneck of Polygonatum Proliferation and Planting
Simultaneously, at present, the phenomenon of low seedling emergence rate, non-uniform emergence time, and even no seedlings in the transplantation of Polygonatum multiflora tissue culture seedlings has seriously hindered the growth of Polygonatum multiflora, planting management and sale of seedlings, and the industry of Polygonatum multiflora. development

Abstract

The present invention discloses an efficient seedling raising method for polygonatum cyrtonema. A medicinal leftover part of rhizomes of 4-5 year-old polygonatum cyrtonema that is robust and disease-free is used as an explant for asexual expansion to obtain polygonatum cyrtonema rooting seedlings, then surfaces of the obtained rooting seedlings are dipped and covered with plant ash, then the covered rooting seedlings are mixed evenly with sand for refrigeration, and then sowing in nursery beds is conducted. The seedling raising of the rhizomes of the polygonatum cyrtonema is conducted according to the method, seedling emergence time is 18-25 d and 120-150 days shorter than that of a conventional tuber seedling raising cycle, and besides, the seedlings emerge neatly, grow well, and high ina survival rate and the efficient seedling raising method can meet needs of large-scale seedling raising.

Description

technical field [0001] The invention belongs to the technical field of medicinal material propagation, and in particular relates to a high-efficiency seedling raising method of Polygonatum multiflora. Background technique [0002] Polygonatum multiflora is a plant of the genus Polygonatum in the family Liliaceae, also known as ginger-shaped Polygonatum, which belongs to high-quality varieties of Polygonatum. According to the records of "Famous Doctors", Polygonatum has the effects of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs and benefiting the kidneys. Along with the increase of market demand for Polygonatum multiflora, people excavate a large amount of wild resources, which not only destroys the ecological environment of Polygonatum multiflora, but also causes the shortage of wild resources of Polygonatum multiflora, so in recent years artificial Polygonatum multiflora Cultivation is also gradually increasing. [0003] Polygonatum m...
