Description

Technical Field

[0001] This utility model relates to a multi-hole tray for cultivating Salvia miltiorrhiza seedlings that promotes root growth. Background Technology

[0002] In modern agriculture, the cultivation techniques of Salvia miltiorrhiza, an important traditional Chinese medicine, are receiving increasing attention. The seedling stage of Salvia miltiorrhiza has a significant impact on its growth and development, especially in the early stages of root growth. Good seedling conditions can effectively promote root development, improve survival rate, and enhance the overall growth quality of the plant. Traditional seedling cultivation methods often rely on ordinary plastic trays or soil substrates. While these methods provide some growing space, they have limitations in promoting healthy root growth. For example, the conventional tray structure may restrict root growth, leading to tangled or uneven root development, affecting the growth rate and quality of Salvia miltiorrhiza seedlings. Furthermore, traditional seedling cultivation methods are inadequate in terms of air circulation and water management, easily resulting in waterlogging and substrate blockage, thus affecting the healthy development of the seedlings.

[0003] Therefore, it is particularly important to develop a multifunctional seedling raising device that can effectively promote the root growth of Salvia miltiorrhiza and improve the survival rate of seedlings. This device not only needs to provide suitable space and air circulation conditions, but also should have functions such as preventing root tangling and optimizing water management. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-hole tray for cultivating Salvia miltiorrhiza seedlings that facilitates rooting.

[0005] A multi-cell seedling tray for promoting root growth of Salvia miltiorrhiza includes a circular or rectangular tray body made of biodegradable polylactic acid in one piece. The tray body has reinforcing ribs along its edges to enhance its overall resistance to deformation. Support feet are evenly distributed at the bottom of the tray to create a gap between the tray and the ground, promoting air circulation. The tray body has 128 cells arranged in a rectangular array. Each cell has an inverted conical structure, with a serpentine protrusion extending upwards from the bottom of the inner wall. The protrusion has a semi-circular cross-section, which guides the Salvia miltiorrhiza roots downwards along a serpentine path, preventing them from coiling. Several circular ventilation holes are located at the bottom of each cell, with drainage channels at their edges to prevent substrate blockage and guide excess water out. A groove is located at the top edge of each cell to fix the seedling substrate and prevent soil loss during watering. The surface of the tray is covered with a removable transparent moisture-retaining cover with ventilation holes to maintain a balanced humidity environment for the seedlings.

[0006] As a further improvement, the thickness of the disc body is 3-5mm, and the width of the reinforcing ribs is 5-8mm.

[0007] As a further improvement, the rectangular array of holes has a row spacing of 25-30mm, a column spacing of 20-25mm, an upper opening size of 30mm×30mm, a depth of 80-90mm, and an inner wall inclination angle of 5°-10°.

[0008] As a further improvement, the radius of the raised semicircle is 0.3-0.5 mm.

[0009] As a further improvement, the diameter of the circular vent is 1.5 mm, the depth of the guide groove is 0.5 mm, and the width is 1 mm.

[0010] As a further improvement, the transparent moisturizing cap is made of PET film with pores of 0.5mm in diameter and a density of 50-80 pores / cm³. 2 .

[0011] Beneficial effects:

[0012] This invention provides a multi-cell seedling tray for promoting root growth in *Salvia miltiorrhiza*. Made of a one-piece molded biodegradable polylactic acid material, it overcomes the shortcomings of traditional seedling devices in terms of root growth, air circulation, and water management. Specific beneficial effects are as follows:

[0013] Promotes root growth: The seedling tray design of this utility model adopts an inverted conical hole and has spiral protrusions on the inner wall, which forces the roots of Salvia miltiorrhiza to grow downward along the spiral path, thereby effectively avoiding the phenomenon of root entanglement, promoting healthy root development, and improving the growth rate of seedlings.

[0014] Improved air circulation: The evenly distributed support feet at the bottom of the tray leave a gap between the tray and the ground, enhancing air circulation, preventing water accumulation and substrate buildup, reducing root suffocation, and ensuring good root respiration.

[0015] Preventing water accumulation: The ventilation holes and drainage channels at the bottom of each hole effectively guide excess water out, preventing root rot caused by excessive moisture and helping to maintain suitable humidity and water balance.

[0016] Stabilizing the seedling substrate: The top of the seedling hole has a groove to fix the seedling substrate, prevent soil loss when watering, ensure substrate stability, and avoid substrate loss and root exposure during the seedling process.

[0017] Environmental humidity control: The transparent moisture-retaining cover not only maintains the humidity balance of the seedling environment, but also has ventilation holes to ensure sufficient air exchange, avoid excessive moisture or dryness, and create an ideal growing environment.

[0018] Environmental friendliness and practicality: Made of biodegradable polylactic acid, it is not only environmentally friendly, but also has good durability and adaptability, making it suitable for long-term use.

[0019] In summary, the multi-hole tray for Danshen seedling cultivation of this invention can significantly improve the seedling environment, promote the healthy growth of Danshen seedlings, increase the survival rate, and improve the overall quality of Danshen. Attached Figure Description
