Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of traditional Chinese medicinal material planting, specifically to a cultivation device for polygonatum sibiricum seedlings. BACKGROUND

[0002] Polygonatum sibiricum is a liliaceae polygonatum plant, which grows in the undergrowth, shrub or shady hillside at an altitude of 800-2800 meters. According to the polygonatum sibiricum recorded in Chinese Pharmacopoeia, it includes the dried rhizomes of liliaceae polygonatum sibiricum, polygonatum sibiricum or polygonatum multiflorum. As a commonly used traditional Chinese medicinal material, polygonatum sibiricum has a long history of medicinal use. Polygonatum sibiricum is sweet and delicious, and its fleshy rhizome is thick, containing a large amount of starch, sugar, fat, protein, carotene, vitamin and various other nutrients. Eating raw or stewing can not only satisfy hunger, but also have the effect of strengthening the body, increasing energy, filling muscles and strengthening bones, which is very beneficial to the body. As a food therapy medicine, polygonatum sibiricum has the effects of tonifying kidney and spleen, benefiting qi and nourishing yin, and strengthening the body, and has good medicinal and edible homology.

[0003] For a long time, the source of polygonatum sibiricum mainly relies on wild collection. With the increasing demand for polygonatum sibiricum in the market and the sharp decrease of wild resources, collecting wild polygonatum sibiricum not only cannot meet the market demand, but also destroys the ecological environment and wild polygonatum sibiricum resources. Artificial planting is the main channel to solve the shortage of polygonatum sibiricum. Polygonatum sibiricum reproduction is divided into asexual reproduction (wild rhizome) and sexual reproduction (seed) for reproduction. Due to the long planting cycle of polygonatum sibiricum, the difficulty of seed collection, low germination rate, long seedling period and serious differentiation of seed propagation offspring, the main cultivation method of polygonatum sibiricum in production is rhizome propagation.

[0004] Artificial planting of polygonatum sibiricum mainly selects land with thick, loose and good drainage to plant, maintains a cool, ventilated and humid environment, avoids strong light direct radiation, and regularly supplements organic fertilizer, which can promote the growth and development of polygonatum sibiricum. Before planting, a cultivation device is needed to cultivate seedlings. The current cultivation device mainly uses sunlight for light supplement, which cannot well control the intensity of light, thus causing poor production of polygonatum sibiricum and a large decrease in quality. At the same time, when the existing cultivation device needs to be transplanted into the land for growth, the internal rhizome is easy to break during the transfer process, thereby affecting the later growth. In addition, during the cultivation process, if it is dry, the soil moisture content is poor, and timely drip irrigation is needed.

[0005] Through retrieval, the patent literature with the authorized announcement number CN220359768U discloses a seedling box for planting rhizoma polygonati, and the patent literature with the application publication number CN118985322A also discloses a seedling box for planting rhizoma polygonati with quantitative drip irrigation. From the disclosed contents of the two patent literatures retrieved, a seedling device for rhizoma polygonati planting is provided from different angles. In order to provide suitable light intensity for rhizoma polygonati seedlings and facilitate later transplantation, a cultivation device different from the cultivation devices disclosed in the prior art is provided to meet the use requirements of artificial rhizoma polygonati planting.
