Description

Technical Field

[0001] The utility model belongs to the technical field of high-quality and efficient production of agricultural and forestry plants, in particular to a test device for the cultivation substrate of polygonatum cyrtonema. Background Art

[0002] Yunnan Polygonatum is mainly produced in Yunnan, Sichuan and Guizhou, China. It grows under forests, in thickets or on shady and wet grass slopes at an altitude of 700-3600 meters. Because Yunnan Polygonatum has high medicinal value, artificial cultivation of Yunnan Polygonatum is necessary. Roots are extremely important for the growth and development of plants, because the growth of the aboveground parts of plants depends on the roots to supply mineral elements and water. Therefore, Yunnan Polygonatum artificially restored is often planted in connected seedling trays during the seedling stage. When the seedlings grow to a predetermined extent, the seedlings and seedling trays are transported to the predetermined location for transplantation. The most important condition for seedling cultivation is the corresponding matrix. Choosing a suitable matrix for cultivation can increase the survival rate and accelerate plant growth.
