The storage tank 401 can store the culture solution, and a heating device can be additionally arranged in the storage tank 401 to control the temperature of the culture solution, and the culture solution in the storage tank 401 can be conveyed into the regulating component 2 through the connecting pipe 402 and the liquid inlet pipe 204.
And secondly, cultivating seedlings, namely placing the developed white tomato seedlings in the cultivation component 3, and placing the device in a proper environment.
Specifically, the white tomato seedlings can be placed in the cultivating cup 305, and the cultivating cup 305 can be placed in the cultivating tube 303, and in the cultivating process, the transition cover 201 forms a communicating vessel structure through the liquid discharge tube 202, the fixing tube 301 and the cultivating tube 303, so that the culture solution in the transition cover 201 can enter the cultivating tube 303, and nutrition supply to the white tomato seedlings in the cultivating cup 305 is realized.
And thirdly, regulating and controlling the culture solution, wherein the height of the culture solution in the cultivation component 3 is regulated by the regulating component 2, so that the white tomato seedlings can smoothly grow.
Specifically, after the culture solution enters the liquid inlet pipe 204, the movable seat 209 moves upwards under the action of the tension spring 210, at this time, the movable seat 209 drives the movable block 211 and the sealing gasket 212 to move upwards, so that the sealing gasket 212 and the liquid outlet hole 206 are misplaced, at this time, the culture solution in the liquid inlet pipe 204 can enter the transition cover 201 through the liquid outlet hole 206, when the culture solution in the transition cover 201 reaches a certain height, the floating ball 219 moves upwards under the action of the buoyancy, the floating ball 219 drives one end of the movable arm 214 to move through the connecting lug 218, so that the movable arm 214 rotates around the pin shaft, at this time, the extending seat 215 at the top end of the movable arm 214 moves downwards, the extending seat 215 presses the pressing rod 208 downwards through the adjusting screw 217, so that the pressing rod 208 drives the movable seat 209 to move downwards, so that the sealing gasket 212 seals the liquid outlet hole 206, at this time, the culture solution stops entering the transition cover 201, and at this time, the liquid level in the transition cover 201 and the cultivation pipe 303 remain constant.
And step four, circularly culturing, wherein the height of the culture solution in the culturing component 3 is regulated and controlled through the regulating component 2, so that the white tomato seedlings can finish culturing and growing.
Especially, along with the gradual growth of seedling root system developed, the consumption of thick root system to the culture solution is faster gradually, in order to mend new culture solution in time this moment, through rotating adjusting screw 217 for the position between adjusting screw 217 and the extension seat 215 is adjusted, thereby the final motion position of movable arm 214 is adjusted when making depression bar 208 push down, make the position of floater 219 adjusted, and then make the inside liquid level height of transition cover 201 regulated and controlled, provide the culture solution of different quantity for the seedling adaptability in different growth periods, in order to guarantee the stability of white tomato seedling cultivation process.
Examples
In the process of culturing the seedlings, along with the growth of the seedlings, the root rot condition is easy to occur due to the consumption of oxygen in the culture solution by the root of the seedlings, slow consumption and flow of the culture solution and the uniformity of the culture solution and the reasons of other substances generated by metabolism, so that the survival rate of the seedlings is reduced. In order to overcome the root rot problem and improve the survival rate of seedlings, the improvement operation is carried out in the following way.
The annular sleeve 302 of the outermost fixed tube 301 is connected with a valve body 309, and the valve body 309 is a relief valve, i.e. when the pressure of the culture fluid in the fixed tube 301 increases to a preset value, the relief valve is automatically opened, and when the pressure decreases to a preset value, the relief valve is automatically closed. Of course, a manual ball valve may be selected and opened manually by a worker. But the relief valve can reduce staff intensity of labour for manual ball valve, improves unmanned operation's effect.
The storage tank 401 is in communication with a liquid supply system that is capable of supplying an oxygen enriched culture liquid under pressure into the storage tank 401 via a liquid supply pump.
In the normal culturing process of seedlings, in order to avoid root rot caused by the reasons, the culture solution needs to flow, the old culture solution is taken away and purified, and a new oxygen-enriched culture solution is fed, so that the sufficiency of oxygen and nutrient substances in the nutrient solution is ensured, and the root rot phenomenon is reduced. Specifically, the liquid supply system supplies the oxygen-enriched culture solution with pressure into the storage tank 401 through the liquid supply pump, the nutrient solution with pressure reaches the movable block 211 through the connecting pipe 402 and the liquid inlet pipe 204, the movable block 211 and the sealing pad 212 are pushed to move upwards by the top of the culture solution with pressure, the tension spring 210 is compressed through the movable seat 209, meanwhile, the compression rod 208 is driven to move upwards, the compression rod 208 drives the floating ball 219 to move downwards through the adjusting screw 217 and the movable arm 214, at the moment, the sealing pad 212 moves upwards, the liquid outlet hole 206 is not blocked, the newly supplied culture solution enters the transition cover 201 through the liquid outlet hole 206, and then is supplied into the culture pipe 303 through the liquid outlet pipes 202 and the fixed pipes 301. As the amount of newly supplied culture fluid gradually increases, when the pressure of the culture fluid in the transition cover 201, the fluid discharge pipe 202 and the fixed pipe 301 increases to a preset value, the valve body 309 is automatically opened, the new culture fluid drives the old culture fluid to flow, and the old culture fluid is discharged into the purification system through the valve body 309 for purification and reuse, thereby realizing new oxygen-enriched culture fluid supply.
In addition, in the actual culturing process, it is found that when the seedling is smaller, the consumption of the culture solution is slower, the movable block 211 and the sealing pad 212 thereon do not open the liquid outlet 206 for a long time, under the long-term soaking of the culture solution, the difficulty of opening the liquid outlet 206 by the movable block 211 and the sealing pad 212 thereon is increased, and the liquid outlet 206 is often opened when the culture solution in the transition cover 201 is excessively consumed, so that the shortage of the culture solution supply is easily caused. In the process of feeding the culture solution with pressure by the method, the liquid outlet hole 206 is opened by the pressure of the oxygen-enriched nutrient solution and the oxygen-enriched culture solution is fed, so that the joint of the liquid outlet hole 206, the movable block 211 and the sealing pad 212 on the movable block 211 can be flushed, the liquid outlet hole 206 is opened by the movable block 211 and the sealing pad 212, and the normal continuous feeding of the culture solution is ensured.
In particular, by rotating the adjusting screw 217, the position between the adjusting screw 217 and the extending seat 215 is adjusted, so that the final movement position of the movable arm 214 is adjusted when the pressing rod 208 is pressed down, the position of the floating ball 219 is adjusted, the liquid level inside the transition cover 201 is adjusted, and when new oxygen-enriched culture solution is fed, the liquid level inside the transition cover 201 and the culture tube 303 is controlled to be at a low liquid level position, so that when the oxygen-enriched culture solution with pressure is fed and before the valve body 309 is opened, the new culture solution with pressure fed into the transition cover 201 and the culture tube 303 through the liquid outlet 206 overflows from the ports of the culture tube 303 directly, and waste of the culture solution is caused.
After the old culture medium is completely discharged and the new oxygen-enriched culture medium is supplied, the liquid pump is stopped to supply the pressurized culture medium into the storage tank 401. As the culture liquid newly supplied into the transition hood 201, the liquid discharge pipe 202, and the fixed pipe 301 decreases, the valve body 309 automatically closes when the culture liquid pressure decreases to a predetermined value. Meanwhile, the floating ball 219 drives the sealing pad 212 to move downwards through the acting force of the movable arm 214 and the adjusting screw 217 on the pressing rod 208 and the acting force of the tension spring 210 on the movable seat 209, and the liquid outlet hole 206 is plugged. By completing the discharge of the old culture solution, the supply of the new culture solution brings enough oxygen and nutrient substances, discharges harmful substances generated by metabolism, ensures the continuous growth of the root of the seedling, avoids the generation of rotten roots and greatly improves the survival rate of seedling culture.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
