Problems solved by technology

For the water-absorbing irrigation method of roots and seedlings, an urgent problem to be solved is: how to avoid the problem that the root seedlings are submerged for a long time because the water level is too high for a long time after soaking the cultivation soil or the cultivation substrate with water, because the long-term soaking of the plants may cause to drown
At present, the corresponding water level adjustment system is usually used to solve this problem. To use the water level adjustment system, a corresponding dynamic drainage structure needs to be arranged, and the overall structure is complicated, which is not conducive to saving cultivation costs.

Embodiment 1

[0021] Such as Figure 1-2 As shown, a siphon irrigation and drainage integrated cultivation device includes a cultivation pipe 1 and a siphon irrigation and drainage integrated structure.

[0022] The cultivation pipe is supported by a vertical frame, the two ends of the cultivation pipe are closed, and the inner space of the cultivation pipe forms a water storage chamber 2, which is supplied with water by an external water supply device or manually added water, and the side walls of the cultivation pipe are spaced apart along the length direction. A plurality of planting cup placement holes communicated with the water storage chamber, each planting cup placement hole is clamped and installed with a planting cup 3, seedlings are planted in the planting cup, the lower section of the planting cup is immersed in the water storage chamber, and the lower section of the planting cup is opened. There are seepage holes or seepage grooves 4.

[0023] The integrated siphonic irrigatio...

Embodiment 2

[0027] Compared with embodiment 1, the difference of this embodiment is: as image 3 As shown, the upper section of the inner tube body 6 seals through the center of the bottom of the outer cylinder body 5 and is socketed with the outer cylinder body. Body 601 and lower tube body 602, specifically, the lower section of upper tube body 601 is inserted into lower tube body 602 and threaded with the lower tube body. Connecting rod 10. During actual use, rotate the cover body 9 to adjust the overlapping size of the external thread section of the cover body 9 and the outer cylinder body 5, so that the cover body 9 lifts up and down without detaching from the outer cylinder body 5. At this time, driven by the connecting rod 10, The upper pipe body 601 will also rotate relative to the lower pipe body 602 synchronously, so that the upper pipe body 601 can be raised and lowered relative to the lower pipe body 602, thereby adjusting the height of the top of the upper pipe body, that is...

Embodiment 3

[0029] Compared with the above-mentioned embodiment, the difference of this embodiment is: as Figure 4 As shown, the inner wall of the lower tube body 602 is pasted with a ring-shaped airbag layer 11, and the airbag layer 11 is connected with an inflatable nozzle 12 through an inflatable tube. The inflatable nozzle 12 is detachably provided with an inflatable bag 13. The air bag is an automatically inflated rubber air bag, and an inflation valve 14 is also arranged at the inflation mouth place. In the specific use process, open the inflation valve 14, squeeze the air bag 13 periodically, and inflate the air bag layer, adjust the inflation amount in the air bag layer 11, and change the expansion degree of the air bag layer 11, thereby adjusting the lower tube The inner diameter of the body can be adjusted to adjust the drainage rate, and the overall internal space of the inner pipe body 6 can also be changed, so as to adapt to irrigation needs more flexibly. Large, so that th...

Abstract

The invention discloses a siphon-type irrigation and drainage integrated cultivation device. The siphon-type irrigation and drainage integrated cultivation device comprises a cultivation pipe and a siphon-type irrigation and drainage integrated structure, a water storage cavity is formed inside the internal space of the cultivation pipe, planting cup mounting holes are formed in the side wall of the cultivation pipe, the siphon-type irrigation and drainage integrated structure comprises an outer cylinder body and an inner pipe body, the two ends of the outer cylinder body are sealed, and a water inlet hole is formed in the side wall of the outer cylinder body; the upper section of the inner pipe body is sleeved with the outer cylinder body, the lower section of the inner pipe body penetrates through the bottom of the cultivation pipe, a gap exists between the top of the inner pipe body and the inner top face of the outer cylinder body, and a water outlet hole is formed in the bottom ofthe inner pipe body. By means of the cultivation device of the structure, after a cultivation medium or soil is infiltrated, the siphon principle is utilized for achieving automatic drainage, the water level is lowered to the position which ensures that plants are not soaked for a long term, and thus the whole process from irrigation to drainage for the plants is automatically and integrally completed; the siphon-type irrigation and drainage integrated cultivation device is simple and reliable in overall structure, and the irrigation and drainage cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a siphon type irrigation and drainage integrated cultivation device. Background technique [0002] In the field of plant cultivation, whether it is soil cultivation or soilless cultivation, irrigation is an essential step. According to different irrigation methods, it can be divided into sprinkler irrigation, drip irrigation and root and seedling water absorption methods. [0003] At present, most of the container cultivation plants are irrigated by root seedlings absorbing water. The specific process is: a water storage area and a planting area are formed in the cultivation container, and the planting area can be directly filled with soil or matrix to cultivate plants, or Plants are cultivated in the form of planting cups, and when watering, the water level in the water storage area rises and submerges the soil or matrix in the planting area, and the water is absorbed ...
