Description

Technical Field

[0001] The present invention relates to the field of crop planting, and in particular to a vertical cultivation system and method in which the light state of crops can be regulated. Background Art

[0002] At present, using culture medium to cultivate plants is a common way of crop cultivation. Most culture media are composed of five types of substances, such as inorganic nutrients, carbon sources, vitamins, growth regulators and organic additives. The success of tissue culture depends to a large extent on the choice of culture medium. But after choosing the right culture medium, how to cultivate the crops in the culture medium under the right conditions is also a very important condition in the crop cultivation process. Among the many culture medium crop cultivation conditions, the conditions and time of light are extremely important. The utility model patent application with publication number CN212212245U discloses a new type of flower floating seedling raising device. By sliding the culture medium in layers, the flowers can be grown under natural light. When irradiating crops with a short growth period, the layers of culture medium can be staggered by sliding rails so that they receive uniform light and the growth rate of the crops tends to be consistent. If the light angle is not good, the ring light group can be started to supplement the light to maintain the crop growth environment and facilitate later transplantation and inspection. This solves the problem of insufficient light for culture medium crops during cultivation. However, this adjustment method is still relatively extensive and cannot finely adjust the light conditions of culture medium crops. In addition, during the crop cultivation process, since the crops in the culture medium must be transplanted in the end, under specific transplanting conditions, excessive light is also likely to occur during cultivation. How to finely adjust and control the light of culture medium crops is an issue that urgently needs to be addressed.

[0011] Furthermore, the diameter width of the disk II is set so that the culture medium body can be displaced, rotated or slid in the X-axis direction on the surface of multiple disks II. The culture medium body is connected to the driving device and is driven by the driving device to rotate or slide.

[0012] Furthermore, the light-blocking system includes a light-blocking plate I and a closing plate II; both the light-blocking plate I and the closing plate II are hinged to the light-blocking horizontal plate through a rotating shaft; both the light-blocking plate I and the closing plate II can be rotated with the light-blocking horizontal plate as the axis to adjust the light-blocking area of the closing plate; the light-blocking system is arranged at the upper end of the culture medium body.

[0024] Step 3: After detecting the growth of seeds and formulating a control strategy, the crop lighting strategy is implemented through a control device; if the current crop growth is normal, turn off the light-blocking system and the supplemental light system, so that the crops can receive normal indoor light.

[0025] Step 4: If the current crop growth situation is in the light-filling state I, the position of the culture medium body is adjusted to the weak light-filling system, and the area of the weak light-filling system is adjusted to maximize the light-filling. At the same time, the height of the culture medium body can be adjusted by the cylinder to change the received light intensity; at the same time, the strong light-filling system and the closed light system can be turned off so that the weak light-filling system can be deployed and the culture medium body does not need to move too much for weak light-filling.

[0026] Step 5: If the current crop growth situation is light-supplementing state II or light-blocking state, adjust the position of the culture medium to the strong light-supplementing system or the light-blocking system; and shut down other systems at the same time.

[0027] Step 6: If it is detected that the current crop growth is irregular, some crops need supplementary light and some need to be blocked; then the position of the culture medium body is moved according to the position of supplementary light and blocking light, and the area position of the supplementary light system and the blocking light system are adjusted to achieve a balanced light receiving for the crops.
