The control method comprises the following specific steps:
s1, numbering the seedling trays 400 entering the spiral tower and recording the numbering in a central control unit;
s2, in the cultivation process, the weight, the moisture content and the plant growth condition of the seedling tray 400 are monitored through the monitoring unit, information is fed back to the central control unit to be recorded and stored, and the central control unit controls the cultivation system to adjust the irrigation and the illumination intensity of the plants in the seedling tray according to the fed-back information;

In some embodiments, the structure of the nursery site 400 is uniquely designed for the cultivation of seeds, and the cultivation control method is improved for the unique structure of the nursery site 400. As shown in fig. 5 and 6, the main body of the seedling raising tray 400 is a tray 410, and the edge of the tray 410 is provided with a side wall 420 which extends along the circumferential direction of the tray 410 and is formed into a circle. The tray 410 has a plurality of grooves 460 for holding seeds on the inner side of the bottom, the grooves 460 are generally square holes or circular holes, the radius or side length is generally 0.5-1mm, the opening thereof is gradually reduced from top to bottom, and the inner side of the grooves 460 is in a circular arc structure. The diameter or width of the uppermost end of the groove 460 is smaller than the maximum diameter of the seed in the height direction when the seed is normally placed in the groove 460, so that the seed can be smoothly caught in the groove 460. Meanwhile, the depth of the groove 460 needs to meet the requirement that when the seeds are clamped in the groove 460, a certain gap is formed between the lower ends of the seeds and the bottom of the groove 460, the ventilation effect below the seeds is guaranteed, a part of nutrient solution can be stored in the groove 460, the lower part of the seeds are soaked in the nutrient solution, or the seeds are not soaked in the nutrient solution but are in the moist and nutrient-rich environment in the groove 460, and the rotten bud phenomenon cannot occur when the nutrient supply of the seeds is sufficient. The bottom of the seedling raising tray 400 is provided with a drain hole 430, and redundant water and nutrient solution in the seedling raising tray 400 can flow out through the drain hole 430.
If the proper amount of nutrient solution is added to each groove 460 individually, the operation becomes very cumbersome and time and labor consuming. If some high-tech equipment is adopted to realize the automatic addition of the nutrient solution, on one hand, the delay in the process is still not avoided, and on the other hand, the cost is greatly increased.
In this embodiment, by combining the drainage hole 430 with the groove 460, when the cultivation apparatus pours the nutrient solution into the tray 410, the nutrient solution initially overflows the upper end of the seed and stays in the tray 410, and is slowly drained into the water receiving tank 500 through the drainage hole 430. Meanwhile, since the seeds are caught at the upper side of the groove 460 and the shape of the seeds is not completely consistent with the groove 460, a gap may exist between the seeds and the groove 460, and at this time, the nutrient solution can slowly permeate into the groove 460 through the gap between the seeds and the groove 460 and be stored at the lower side of the groove 4603. By controlling the size of the drain hole 430 and the single pouring amount of the nutrient solution, the time of the nutrient solution poured once at the bottom of the tray 410 can be effectively controlled, so that the amount of the nutrient solution stored in the groove 460 can be controlled, the lower part of the seed is soaked in the nutrient solution, or the seed is not soaked in the nutrient solution but is in a humid and nutrient-rich environment in the groove 460, and the effect of preventing the bud rot phenomenon while ensuring the sufficient nutrient supply of the seed is achieved.
In addition, through equidistant a plurality of recesses 460 that set up in tray 410, after the seed in recess 460 sprouted the growth, its root system can be around recess 460's circumference growth, and because the interval between the adjacent recess 460 is less, generally be 0.5-1.5mm for most root systems can twine together, do benefit to whole dish when the results and take out, avoided the emergence of the condition such as partial finished product scatter, solved and educated root system in the seedling tray 400 and caused to batch to upwarp because of the lack of water, be unfavorable for the problem of reunion.
When the seedling raising tray 400 adopts the above structure, the concrete operation of the watering in step S2 is as follows: during irrigation, the central control unit analyzes the time that fluid needs to stay in the seedling raising tray 400 according to the information fed back by the monitoring unit, judges the height of the water level required by irrigation in the seedling raising tray 400 according to the sizes of the seedling raising tray 400 and the drain holes 430, and stops irrigation when the sensing device senses that the water level in the seedling raising tray 400 reaches the required height.
By the cultivation control method, the cultivation process of the seedling tray in the spiral tower can be monitored and adjusted in real time systematically and completely, a matched irrigation method is designed according to the unique structure of the seedling tray 400, and the production efficiency and the cultivation effect of seedlings and seeds are effectively improved.
In some embodiments, the nursery site transport system is modified to accommodate the drainage design of the nursery site 400. As shown in fig. 3 to 5, the seedling tray transfer system mainly includes a cart 200 and a cart driving assembly 300. The trolley driving assembly 300 includes a chain guide 310, a chain 320 disposed in the chain guide, and a chain driving mechanism 330 for driving the chain 320 to move, wherein the chain guide 310 is aligned with the extending direction of the track 100 and disposed inside the track 100. The chain driving mechanism 330 includes a motor 341 disposed at the bottom of the tower, a main shaft 342 drivingly connected to an output shaft of the motor 341, and a gear sleeved on the main shaft 342. Specifically, the chain guide 310 has a notch near the main shaft 342 for the gear to extend into to engage the chain 320, i.e., only the teeth near a portion of the chain engage the chain 320. When the motor 341 controls the main shaft 342 to rotate, the gear rotates to drive the chain 320 to move along the track 100. In some embodiments, each tower body is provided with two chain driving mechanisms 340, which are respectively located at two ends of the tower body, and the number and the position of the gears sleeved on the main shaft 342 correspond to the number of layers of the tower body, i.e. the chain of each layer of the tower body has a set of engaged gears.

In some embodiments, the water receiving groove 500 is installed at the outer side of the rail 100 in the same direction as the extending direction of the rail 100, and the height of the chain guide 310 is higher than that of the directional pulley 230. When the cart 200 is placed on the rail 100, the upper end surface of the support plate 220 is an inclined surface having a height gradually decreasing from the inside of the rail 100 to the outside of the rail 100, and thus the seedling raising tray 400 placed on the support plate 220 is also inclined. Meanwhile, a drain hole 430 is provided at one side of the bottom of the seedling raising tray 400, and the drain hole 430 is located outside the rail 100 when the seedling raising tray 400 is placed on the support plate 220. In some embodiments, the chain 320 is provided with pads on the upper side of the track 100, and the height of the connecting plate 210 can be adjusted by setting the thickness and number of the pads, so as to adjust the inclination of the supporting plate 220, generally, the inclination of the supporting plate 220 is 1-3 degrees. Through the arrangement, redundant water or nutrient solution in the seedling raising tray 400 can flow to the outer side of the track 100 and flow to the water receiving tank 500 through the drain holes 430, and flow to corresponding recovery equipment along the water receiving tank 500, so that the recovery of the water and the nutrient solution is realized, resources are saved, and the influence on the surrounding environment and the work of a conveying system caused by the flow of the water or the nutrient solution on the track 100 is avoided.
In order to ensure that the penetration rate of the nutrient solution into each of the grooves 460 is uniform by matching the positions of the water receiving tank 500 and the drain hole 430, and considering the flowing direction of the nutrient solution in the tray 410, the fluid supply unit pours the nutrient solution into the tray 410 from the side of the tray 410 away from the drain hole 430, so that the residence time of the nutrient solution in each position of the tray 410 is approximately the same when the nutrient solution flows in the tray 410, and the penetration into the grooves 460 is uniformly maintained. Meanwhile, the diameter size of the cultivated seeds needs to be preliminarily screened, the size of the same batch of seeds is kept consistent as much as possible, and the gap between the seeds and the groove 460 is small when the seeds are clamped in the groove 460. It should be noted that the nutrient solution here includes water and the rest of the prepared liquid for culturing the seeds.
It is worth mentioning that the spiral structure of the tower body is fully considered by the design of the water receiving tank 500, and the seedling tray guides water and nutrient solution, so that the structure of the seedling tray conveying system is fully utilized. In particular, the protrusions 330 are engaged with the through holes of the connecting plate 210 such that the protrusions 330 can freely extend and contract within the through holes when the height of the shoe or chain guide 310 is adjusted, thereby adjusting the inclination of the supporting plate 220. The drainage structure of this embodiment does not make too much useless configuration on educate seedling tray conveying system's basis, and design idea and structure are very ingenious, when realizing the function, have simplified the structure and the installation degree of difficulty of water planting equipment as far as possible, have practiced thrift the cost.
In addition, in order to improve the structural strength of the seedling raising tray 400, a reinforcing rib 440 is provided on the outer side surface of the seedling raising tray 400. The reinforcing ribs 440 form a criss-cross net structure at the outer side of the bottom of the tray 410, and a concave pit 450 with a fixed shape is formed at the middle part of the outer side of the bottom of the tray 410, the cross section of the concave pit 450 is a figure with straight edges, such as a square, a triangle, etc., and the upper side of the supporting plate 220 is provided with matched convex blocks. Through the block of pit 450 and lug, make educate seedling tray 400 and can place steadily on dolly 200, can not take place to remove for fluid supply system can accurately water to educating seedling tray 400 in, unnecessary water and nutrient solution also can accurately flow to the water receiving tank 500 along the slope of backup pad 220. Meanwhile, due to the existence of the reinforcing rib 440, a gap is formed between the bottom of the tray 410 and the support plate 220, so that water and nutrient solution can more conveniently flow out of the drainage hole 430. In some embodiments, the drainage hole 430 is disposed at an edge of the bottom of the tray 410, and the edge of the bottom of the tray 410 is not provided with the reinforcing rib 440, so that the excess water and the nutrient solution can smoothly flow into the water receiving tank 500 without being blocked.
When the water culture equipment works, the seedling culture disc 400 is placed above the trolley 200, and the connecting plate 210 is directly sleeved on the protrusion 330 of the chain 320, so that the trolley 200 is fixed on the chain 320. The chain driving mechanism operates to drive the cart 200 to move along the spiral track 100, and in the process, the fluid supply system, the illumination system and the ventilation system operate to provide nutrient solution, water, illumination and the like required for growth of seeds or seedlings in the seedling raising tray 400. The moving speed of the chain 320 is controlled to make the cart 200 move on the track 100 for a sufficient time to complete the cultivation of the seeds or seedlings.
