AI Technical Summary

Technical Problem

Traditional seedling raising devices lack a pre-set thin-walled cutting guide structure, which makes operation laborious and easily damages the root system. The bottom of the container cannot keep moist and is prone to slipping and tipping over, affecting the root growth and transplant survival rate of wet-processed pine clonal seedlings.

Method used

Design a seedling device that includes a deformable root control plate, with inner and outer grooves forming a thin-walled area for guiding cutting, combined with a perforated cover plate for moisture retention and an anti-slip pointed rod for anchoring, to achieve precise cutting, moisture retention and stable fixation.

Benefits of technology

It achieves labor-saving cutting, moisture retention and device stability, promotes the growth of multi-level fibrous roots, and improves the stress resistance and seedling recovery efficiency of wet-processed pine clonal seedlings.

Claims

1. A clonal Pinus massoniana seedling rooting device, comprising a deformable root control plate (101), characterized in that: The root control plate (101) has several inner grooves (102) spaced apart on its inner side. Several ventilation holes (103) are spaced apart on the inner side of the root control plate (101) adjacent to the inner grooves (102). Several outer grooves (104) are spaced apart on the outer side of the root control plate (101) opposite to the inner grooves (102). The inner grooves (102) and outer grooves (104) opposite to each other form a thin-walled area in the root control plate (101). An extension cylinder (106) is fixedly installed on the outer side of the root control plate (101) opposite to the ventilation holes (103). The extension end of the extension cylinder (106) has a through hole (107) and communicates with the ventilation holes (103).

2. The device for controlling the root growth of seedlings of a clone of Pinus strobus according to claim 1, characterized in that: The root control plate (101) is deformed and bent at both ends to form a cylindrical structure (108). When the root control plate (101) is deformed, the inner vent (103) at one end is sleeved on the outer extension cylinder (106) at the other end and fixed by plastic bolts.

3. The device according to claim 2, wherein the device is used for the seedling and root control of Pinus strobus. After the root control plate (101) forms a cylindrical structure (108), an assembly plate (110) is embedded in the inner groove (102) at the bottom of its inner wall. A slot (111) is opened at the top of the assembly plate (110), and a hollow cover plate (112) is embedded in the slot (111).

4. The device according to claim 3, wherein the device is used for the seedling and root control of Pinus strobus. An assembly cylinder (113) is fixedly installed at the bottom of the assembly plate (110). The assembly cylinder (113) is connected to the slot (111), and a hollow support plate (114) is fixedly installed inside the assembly cylinder (113).

5. The root control device for clonal wet-mixed pine seedling cultivation according to claim 4, characterized in that: A non-woven fabric receiving cavity is formed between the hollowed-out support plate (114) and the hollowed-out cover plate (112), and a bottom plate (116) is fixedly installed at the middle of the bottom end of the assembly cylinder (113).

6. The device according to claim 5, wherein the device is used for the seedling and root control of the clone of wet-grown Pinus strobus L. The base plate (116) has a through hole (117) in the middle, and a number of anti-slip pointed rods (118) are fixedly installed on the bottom end of the base plate (116) extending outward along the through hole (117).
