Method for quick seedling culture of polygonatum cyrtonema seeds

Abstract

The invention discloses a method for quick seedling culture of polygonatum cyrtonema seeds. The method comprises the steps of scrubbing harvested ripe polygonatum cyrtonema fruits to obtain clean seeds, mixing the seeds and wet sand according to the ratio of 1:3 and then placing the mixture at the outdoor shade place; laying the seeds having undergone sand storage treatment for 90-100 days on wet withered grass, covering the seeds with wet withered grass, and performing sprouting on indoor conditions of 20-25 DEG C; performing row planting of the seeds having undergone sprouting in a well prepared seedbed, covering the seeds with withered grass after the seeding and watering the seeding, finally covering the seeds with a shading mesh; after the emergence of seedlings, removing the withered grass and the shading mesh, arranging the shading mesh above the seedbed to keep the seedbed wet, and timely performing weeding for seedlings and applying farm manure once to let the seedlings be strong. The practice proves that when the method is adopted to culture the seedlings, the germination rate and the emergence rate of the polygonatum cyrtonema seeds can be greatly improved, the seedling culture time is shortened, and the planting of plenty of polygonatum cyrtonema is guaranteed.

Description

technical field [0001] The invention relates to a rapid seedling raising method of Polygonatum polyflora seeds, belonging to the technical field of plant cultivation. Background technique [0002] The tuber of Polygonatum multiflora is one of the three Polygonatum medicinal materials stipulated in the Pharmacopoeia. It can be used as medicine or as a tonic. The Polygonatum plant itself can also be viewed indoors. Now there is a large demand in the domestic market, and it is even exported to Japan and South Korea. The market price is relatively high and showing an upward trend. Many traditional Chinese medicine planting companies and cooperatives want to plant on a large scale, but it is difficult to buy seedlings and cannot find a stable and professional seedling supply base. The technology is immature and the seedling breeding period is long, so the only way to plant it is to purchase wild Polygonatum resources excavated from farmers and use tubers for propagation.

Problems solved by technology

However, now the wild resources of sealwort are less and less, and tubers are used for asexual reproduction for a long time, which is easy to carry viruses, and the species degrades, resulting in a decrease in the yield and quality of sealwort, and the loss of the income of farmers.
