Technical Field

[0001] This utility model relates to the field of seedling tray technology, specifically to an intelligent seedling tray based on biochar-coconut coir substrate. Background Technology

[0002] Using chili peppers as the research object, four types of biochar materials were prepared through pretreatment: original biochar, acid-modified biochar, alkali-modified biochar, and acid-modified biochar loaded with nutrients. These biochar materials were then orthogonally compounded with three matrix materials: coconut coir, perlite, and vermiculite. Experiments showed that the acid-modified biochar loaded with nutrients, combined with coconut coir, perlite, and vermiculite in a ratio of 4:9:3:4, exhibited the best overall effect and was suitable for chili pepper seedling cultivation, demonstrating promising prospects for widespread application.

[0003] Using seedling trays is a common method in modern agriculture for cultivating chili seedlings. Seedling trays provide a suitable growing environment for chili seedlings, facilitate centralized management, and improve seedling efficiency and quality. During the process of cultivating chili seedlings using seedling trays, the addition of fertilizer and water is necessary. However, different fertilizers should be applied according to the growth status of the seedlings and the fertility of the soil. Although current seedling trays can provide a good place for the cultivation of chili seedlings, they do not have the function of automatically testing and fertilizing the soil. The convenience of cultivation work needs to be further improved. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 The intelligent seedling tray based on biochar-coconut coir substrate provided by this utility model includes: a base box 1 and a tray body 2 installed on the top of the base box 1. It also includes: a controller 3 installed on one side of the outer wall of the base box 1; a soil and fertilizer sensor 4 is embedded in one side of the outer wall of the tray body 2, with the detection end of the soil and fertilizer sensor 4 extending into the tray body 2; support plates 5 are installed at both ends of the top outer wall of the tray body 2; rotating rods 6 are rotatably installed on the outer walls of the two support plates 5; an electric rotating platform 7 is installed on one side of the outer wall of one of the support plates 5; the rotating part of the electric rotating platform 7 is connected to one of the rotating rods 6; a conductive slip ring 8 is installed on the outer wall of one of the rotating rods 6; a connecting plate 9 is provided on the opposite side of the outer wall of the two rotating rods 6; a soil loosening component 10 is installed at the bottom of the connecting plate 9; a liquid absorption component 11 is laid on the bottom inner wall of the tray body 2; and multiple equidistant liquid supply components 12 are installed on the bottom inner wall of the base box 1.

[0021] It should be noted that the cultivation soil formed by biochar-coconut coir substrate can be placed in the tray 2, and pepper seedlings can be cultivated in the soil. Before cultivation, the soil surface can be loosened by the soil loosening component 10 to facilitate seedling rooting. After loosening, the rotating rod 6 can be rotated 180° by the electric rotating table 7 so that the soil loosening component 10 faces upward to avoid affecting seedling development. The soil fertilizer sensor 4 can monitor the soil moisture and the content of various trace elements. The multiple liquid supply components 12 can hold liquid fertilizer or water of different elements, according to the growth of pepper seedlings. When the soil fertilizer sensor 4 detects a deficiency of a certain trace element in the soil, it transmits a signal to the controller 3. The controller 3 automatically controls the liquid fertilizer supply component 12 containing the corresponding trace element to rise, so that the bottom of the liquid absorption component 11 is immersed in the liquid fertilizer supply component 12 and absorbs the liquid fertilizer directly into the soil. When the soil fertilizer sensor 4 detects that the content of the trace element in the soil is sufficient, the controller 3 controls the corresponding liquid fertilizer supply component 12 to descend, so as to avoid the liquid fertilizer supply component 12 from continuously absorbing too much, thereby realizing the function of automatically detecting and fertilizing the cultivation soil, and further improving the convenience of cultivation work.

[0022] In a preferred embodiment, the soil-dredging assembly 10 includes an electric slide 1001, a first electric push rod 1002 mounted on the bottom of the sliding member of the electric slide 1001, a horizontal plate 1003 mounted on the bottom of the piston rod of the first electric push rod 1002, and a plurality of equally spaced insert rods 1004 mounted on the bottom of the horizontal plate 1003.

[0023] It should be noted that the first electric push rod 1002 can be lowered to insert the insertion rod 1004 into the soil, and the electric slide table 1001 can be used to move the insertion rod 1004 to loosen the soil.

[0024] In a preferred embodiment, the liquid absorption assembly 11 includes a cotton rope net 1101, a plurality of equally spaced absorbent cotton ropes 1102 connected to the bottom of the cotton rope net 1101, and a weight 1103 fixed to the bottom of the absorbent cotton ropes 1102; the liquid supply assembly 12 includes a second electric push rod 1201, a liquid supply tank 1202 mounted on the top of the piston rod of the second electric push rod 1201, a non-contact liquid level sensor 1203 mounted on one side of the outer wall of the liquid supply tank 1202, a liquid filling pipe 1204 connected to one side of the outer wall of the liquid supply tank 1202, and a through hole 1205 opened on the top of the liquid supply tank 1202.

[0025] It should be noted that: the second electric push rod 1201 can drive the liquid supply tank 1202 to rise, so that the absorbent cotton rope 1102 is immersed in the liquid fertilizer. The liquid fertilizer enters the cotton rope net 1101 through the absorbent cotton rope 1102 and is directly transferred into the soil. When fertilization is not needed, the second electric push rod 1201 can drive the liquid supply tank 1202 to fall to a certain height. At this time, the weight 1103 is pressed against the inner wall of the top of the liquid supply tank 1202 and blocks the bottom of the through hole 1205 to prevent the liquid fertilizer from evaporating. The non-contact liquid level sensor 1203 can monitor the change of liquid fertilizer level in the liquid supply tank 1202. When the liquid fertilizer level in the liquid supply tank 1202 reaches the height of the non-contact liquid level sensor 1203, the controller 3 will automatically issue an alarm to remind people to replenish it in time.

[0026] In a preferred embodiment, an installation opening is provided on one side of the outer wall of the base box 1, and a door panel 13 is hinged to the inner wall of the installation opening.

[0027] It should be noted that the door panel 13 can be opened to facilitate the replenishment of liquid fertilizer into the liquid supply tank 1202 through the liquid addition pipe 1204.

[0028] In a preferred embodiment, both the electric slide table 1001 and the first electric push rod 1002 are connected to the inner slip ring rotor of the conductive slip ring 8 via wires.

[0029] It should be noted here that the problem of wire entanglement should be avoided during the rotation of the electric slide table 1001 and the first electric push rod 1002.

[0030] Working principle: The cultivation soil formed by biochar-coconut coir substrate can be placed in the tray 2, and pepper seedlings can be cultivated in the soil. Before cultivation, the first electric push rod 1002 can be lowered to insert the insertion rod 1004 into the soil. The electric slide 1001 drives the insertion rod 1004 to move and loosen the soil to facilitate the rooting of the seedlings. After loosening, the electric slide 1001 drives the insertion rod 1004 to rise and return to its original position. The electric rotating table 7 drives the rotating rod 6 to rotate 180° so that the insertion rod 1004 faces upward to avoid affecting the development of the seedlings.

[0031] The soil fertilizer sensor 4 monitors soil moisture and the content of various trace elements. Multiple liquid supply tanks 1202 can hold liquid fertilizers or water containing different elements. When the soil fertilizer sensor 4 detects a deficiency of a certain trace element in the soil, it transmits a signal to the controller 3. The controller 3 automatically controls the corresponding second electric push rod 1201 to extend upwards, causing the liquid supply tank 1202 containing the corresponding trace element liquid fertilizer to rise. This allows the absorbent cotton rope 1102 to immerse itself in the liquid fertilizer. The liquid fertilizer then passes through the absorbent cotton rope 1102 into the cotton rope net 1101, directly transferring it into the soil. When the soil is found to contain sufficient trace elements and fertilization is not required, the second electric push rod 1201 can be used to lower the liquid supply tank 1202 to a certain height. At this time, the weight 1103 will press against the inner wall of the top of the liquid supply tank 1202 and block the bottom of the through hole 1205 to prevent the liquid fertilizer from evaporating. The non-contact liquid level sensor 1203 can monitor the change in the liquid fertilizer level in the liquid supply tank 1202. When the liquid fertilizer level in the liquid supply tank 1202 reaches the height of the non-contact liquid level sensor 1203, the controller 3 will automatically issue an alarm to remind people to replenish the fertilizer in time. This realizes the function of automatically detecting and fertilizing the cultivation soil, further improving the convenience of cultivation work.
