Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a corn breeding and cultivating device disclosed in an embodiment of the present application is mainly composed of a nutrition pool 11, a guide rail 12, a culture substrate 13, a culture hole 14, a siphon pipe 15, a culture substrate 16, and the like, wherein the nutrition pool 11 is used for storing a nutrient solution, the guide rail 12 is installed on an inner wall of the nutrition pool 11, and the guide rail 12 is used for placing the culture substrate 13.

The culture substrate 13 is slidably coupled to the guide rail 12 and can slide on the guide rail 12 under the guide of the guide rail 12, and the culture substrate 13 can be directly removed from the guide rail 12. In some possible implementations, the bottom surface of the culture substrate 13 is provided with a guide strip, and the guide strip can be clamped into a guide groove on the guide rail 12 and can slide in the guide groove.

The main considerations for the ability of the substrate 13 to slide on the rails 12 are that the growth conditions of the seeds on the substrate 13 are different, that the growth rate of the seeds on the substrate 13 is high, that the growth rate of the seeds on the substrate 13 is slow, and that the size of the substrate 13 being used may vary.

The culture substrates 13 can slide on the guide rails 12, so that the width of the gap between adjacent culture substrates 13 can be adjusted, and the culture substrates 13 can be taken conveniently.

Culture holes 14 are uniformly distributed on the culture substrate 13, the culture holes 14 are used for placing seeds to be germinated, a plurality of siphon pipelines 15 are further arranged on the culture substrate 13, the number of the siphon pipelines 15 is the same as that of the culture holes 14, each siphon pipeline 15 is only communicated with one culture hole 14, moreover, a culture substrate 16 is filled in each siphon pipeline 15, the culture substrate 16 is used for absorbing nutrient solution in the nutrient pool 11, and the seeds are placed on the culture substrate 16, so that the seeds can absorb the nutrient solution in the culture substrate 16 for development.

In combination with a specific process, the liquid level of the nutrient solution in the nutrient pool 11 can be adjusted, and when the nutrient solution in the nutrient pool 11 can submerge the end of the siphon pipe 15 far away from the culture substrate 13, the culture substrate 16 in the siphon pipe 15 starts to absorb the nutrient solution in the nutrient pool 11 and stores the nutrient solution for germination of seeds.

After the nutrient solution is soaked for a period of time, a part of the nutrient solution in the nutrient pool 11 is extracted, and at the moment, the liquid level in the nutrient pool 11 can immerse the end of the siphon pipe 15 far away from the culture substrate 13 or separate from the end of the siphon pipe 15 far away from the culture substrate 13.

After the liquid level in the nutrient pool 11 is only in contact with the end of the siphon pipe 15, a small part of nutrient solution enters the siphon pipe 15 by means of siphon, and wets the culture substrate 16 in the siphon pipe 15. When the liquid level in the nutrient pool 11 is separated from the siphon 15, a part of the nutrient solution in the culture substrate 16 flows back to the nutrient pool 11 under the action of gravity.

The control of the wettability of the culture substrate 16 can be achieved by adjusting the height of the liquid surface in the nutrient bath 11, for example, by sufficiently soaking the culture substrate 16 every ten days and by slightly soaking the end of the culture substrate 16 every two to three days at two adjacent time points of sufficient soaking.

Referring to fig. 1 and 2, in an embodiment of the corn breeding and cultivating device provided as an application, the shape of the siphon pipe 15 is adjusted, and particularly, the flow area of the siphon pipe 15 tends to decrease in a direction away from the culture substrate 13. Thus, the inner wall of the siphon tube 15 can bear a part of the weight of the culture substrate 16, and the culture substrate 16 can be prevented from slipping off the siphon tube 15.

Referring to fig. 1 and 2, a liquid level adjusting tank 21, a water pump 22 and a controller 6 are added as an embodiment of the corn breeding and cultivating device provided by the application, and the liquid level adjusting tank 21 is used for temporarily storing the nutrient solution led out from the nutrient tank 11 and returning the nutrient solution to the nutrient tank 11 again at a proper time.

Two ends of the water pump 22 are respectively communicated with the nutrient pool 11 and the liquid level adjusting pool 21, and are used for injecting part of nutrient solution in the nutrient pool 11 into the liquid level adjusting pool 21 or injecting part of nutrient solution in the liquid level adjusting pool 21 into the nutrient pool 11.

The working process of the water pump 22 is controlled by the controller 6, and the controller 6 stores a set program, so that the water pump 22 can be controlled to work within a set time, and the liquid level in the nutrition pool 11 can be changed according to the setting.

Referring to fig. 2, as an embodiment of the corn breeding and cultivating device provided by the application, a first liquid level sensor 23 is added in the nutrition pool 11, and the first liquid level sensor 23 is located on the inner wall of the nutrition pool 11 and is used for monitoring the highest liquid level in the nutrition pool 11.

When the first liquid level sensor 23 feeds back a signal to the controller 6, the water pump 22 stops operating.

Referring to fig. 2, as an embodiment of the corn breeding and cultivating device provided by the application, a second liquid level sensor 24 is added in the nutrition pool 11, and the second liquid level sensor 24 is located on the inner wall of the nutrition pool 11 and is used for monitoring the lowest liquid level in the nutrition pool 11.

When the second liquid level sensor 24 feeds back a signal to the controller 6, the water pump 22 stops operating.

The first level sensor 23 and the second level sensor 24 function to enable the liquid level in the nutrition tank 11 to be more accurate.

Referring to fig. 2, as a specific embodiment of the maize breeding and cultivating device provided by the application, a circulating pump 25 is further added, and an input end and an output end of the circulating pump 25 are both connected with the nutrition pool 11, so as to drive the nutrient solution in the nutrition pool 11 to flow, and to make the nutrient solution in the nutrition pool 11 more uniform.

It should be understood that the layering phenomenon of the nutrient solution can occur during the long-time standing process, if the liquid level height in the nutrient pool 11 is only adjusted, the situation of insufficient nutrition can occur on the seeds on the culture substrate 16, and after the circulating pump 25 is added, the layering phenomenon can be effectively avoided by driving the nutrient solution in the nutrient pool 11 to flow.

Referring to fig. 3, the controller 6 may be a CPU, microprocessor, ASIC, or one or more integrated circuits for controlling the execution of the programs described above.

The controller 6 mainly includes a CPU601, a RAM602, a ROM603, and a system bus 604, wherein the CPU601, the RAM602, and the ROM603 are connected to the system bus 604.

The water pump 22 and the circulating pump 25 are connected to the system bus 604 through a control circuit, and the first liquid level sensor 23 and the second liquid level sensor 24 are connected to the system bus 604 through a communication circuit.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
