[0012] A method for using a transport container for cultivating forestry seedlings comprises the following steps: Step 1: The container body and the height-enhancing cover are made of breathable materials. Before placing the seedlings in the container body, lay a layer of grass mat on the surface of the drainage tray to help drain water and keep the soil moist to prevent the roots from rotting due to water accumulation; Step 2: Carefully take the seedlings out of the cultivation container to avoid damaging the root system, then place the seedlings in rows and columns in the container body, ensuring that the roots are not entangled with each other, and turn the rotating bar clockwise. The height of the two displacement blocks gradually increases, which also drives the height-increasing cover to rise.

The seedlings are then placed on the grass mat. The rotating bar is manually rotated clockwise to drive the threaded rod fixedly connected to it to rotate, thereby driving the displacement block threadedly sleeved thereon to move upward. As the two displacement blocks move synchronously, the heightening cover is driven to move upward. The height of the heightening cover increases, thereby increasing the protection area of the outer surface of the seedlings to prevent the seedlings from being squeezed by external forces and damaged. The type of seedlings is written on the surface of the classification sticker, and the classification sticker is bonded to the surface of the heightening cover to facilitate the distinction of the seedlings. The bottom surfaces of the two suction cups are respectively adsorbed to the transport table surface, thereby enhancing the firmness of the container body for transportation.
[0014] 2. The present invention cooperates with the fixed rod, contact block, limit strip, limit hole, liquid receiving cover, metering value and wrapping cover through the provided fixing rod, contact block, limit strip, limit hole, liquid receiving cover, metering value and wrapping cover, so that the moisture in the seedlings drips into the inside of the liquid receiving cover through the drainage hole. The middle part of the liquid receiving cover is made of transparent glass, and the water storage value can be seen through the metering value. By rotating the two concave holes in the opposite direction to make them detached from the inside of the reinforcement strip, the liquid receiving cover can be disassembled from the bottom of the container body in time, which is convenient for processing the collected moisture. The contact block can move up and down at one end of the fixing rod, and the position height of the suction cup can also be adjusted, which is convenient for adsorption according to the height of the transport table, thereby increasing the use range of the transport container. After one end of the limit strip is embedded in the inside of the limit hole and the circular hole, the three are threadedly connected, so that the L-shaped plate and the contact block can be limited and fixed, thereby ensuring the stability of the convex plate and the suction cup.
[0015] 3.

[0024] The working principle and use process of the present invention: Forestry seedling cultivation is an important link in forestry production. It mainly promotes the germination, growth and healthy development of tree seeds through artificial methods, and provides qualified seedlings for subsequent forest planting, creation and restoration. The seedlings are cultivated inside the cultivation container. The transport container for forestry seedling cultivation is mainly used to ensure the growth environment of the seedlings during transportation, reduce damage and drought, and ensure that the seedlings can arrive at the destination safely and healthily. The seedlings need sufficient nutrition supply during the growth process. Organic fertilizer and chemical fertilizer are combined to meet the needs of seedlings at different growth stages. The health status of the seedlings is checked regularly to detect signs of diseases and insect pests in time. The heights of the seedlings are different, and the protection height of the transport container for the seedlings is specific and localized. The seedlings are easily subjected to external impact and pressure during transportation, which may cause mechanical damage to the branches, leaves and roots. The space limits the growth of the seedlings. The lack of stability of the transport container and the transport platform may cause tilting and shaking during transportation. The root system may become loose and damaged. The moisture of the seedling root system cannot be collected and cleaned in time. The root system may suffer from hypoxia due to long-term immersion, which may affect the healthy growth of the seedlings. The container body 1 and the height-increasing cover 7 are made of breathable materials. Before placing the seedlings into the container body 1, a layer of straw mat is first laid on the surface of the drainage tray 25 to help drain water and keep the soil moist to prevent the roots from rotting due to water accumulation. The seedlings are then placed on the straw mat. The rotating bar 6 is manually rotated clockwise to drive the threaded rod 3 fixed thereto to rotate, which also drives the rotating bar 6 to rotate clockwise. The displacement block 5 threadedly sleeved therewith moves upward, and with the synchronous movement of the two displacement blocks 5, the heightening cover 7 is driven to move upward. The height of the heightening cover 7 increases, which increases the protection area of the outer surface of the seedlings to prevent the seedlings from being squeezed and damaged by external forces. The types of seedlings are written on the surface of the classification sticker 8, and the classification sticker 8 is adhered to the surface of the heightening cover 7 to facilitate the distinction of seedlings. The bottom surfaces of the two suction cups 15 are respectively adsorbed on the transportation table, which enhances the firmness of the container body 1 for transportation. The moisture in the seedlings drips into the interior of the liquid receiving cover 18 through the drainage holes 26. The middle part of the liquid receiving cover 18 is made of transparent glass, and the water storage value can be seen through the metering value 19. The two concave holes 23 are manually rotated in the opposite direction to separate them from the inside of the reinforcement strip 22. The liquid collecting cover 18 can be disassembled from the bottom of the container body 1 in time, which is convenient for processing the collected water, solving the problem that the water of the seedling root system cannot be collected and cleaned in time, and the root system will be lack of oxygen due to long-term immersion, which affects the healthy growth of the seedling. The contact block 12 can move up and down at one end of the fixing rod 11, and the position height of the suction cup 15 can be adjusted, which is convenient for adsorption according to the height of the transportation table, increasing the use range of the transportation container, and after one end of the limiting strip 16 is embedded into the limiting hole 17 and the circular hole, the three are threadedly connected, so that the L-shaped plate 10 and the contact block 12 can be limited and fixed, ensuring the stability of the convex plate 13 and the suction cup 15, and the top of the wrapping cover 20 is tightly fitted with the bottom of the container body 1.The sealing between the bottom of the container body 1 and the liquid receiving cover 18 is ensured. After one end of the plurality of clip strips 30 is sequentially embedded in the inside of the clip hole, the auxiliary gasket 24 and the drain pan 25 can be installed.
