Description

Technical Field

[0001] The invention belongs to the technical field of soilless cultivation, in particular to a method for preparing a Clivia culture medium. Background Art

[0002] Clivia miniata (scientific name: Clivia miniata), also known as sword-leafed lycoris and large-leafed lycoris, is a perennial herb of the genus Clivia in the Amaryllis family. It has high ornamental value. At present, the cultivation of Clivia in China mainly follows traditional cultivation techniques, using traditional materials such as soil and gravel as planting media. It has high requirements for temperature, humidity, pots, and daily care. Therefore, it is difficult to cultivate in homes and offices, with a low survival rate, and most of them can only be planted in pots specially designed for orchids, which has great limitations.

[0003] Soilless cultivation can generally be divided into two types: substrate-free cultivation and substrate cultivation. Among them, substrate-free cultivation can be further divided into hydroponics and mist cultivation. Regardless of whether it is soilless cultivation with or without solid substrate, nutrient solution must be used to provide the nutrients and water required for crop growth. Therefore, the success of soilless cultivation depends to a large extent on whether the nutrient solution formula and concentration are appropriate and whether the nutrient solution can meet the requirements of different growth stages of plants.

[0004] The nutrient solution formulas currently used are mostly general or basic formulas for flowers. Although the nutrients they provide are comprehensive, they are not configured in the proportions required by Clivia. When cultivating Clivia in soilless culture, general nutrient solutions are often used, which can easily prevent the plants from growing well and affect the quality of Clivia. Therefore, different and targeted nutrient solutions need to be designed according to the characteristics of different plants. At the same time, in the process of cultivating Clivia, the mother liquor of the nutrient solution is prone to precipitation and crystallization, and it is easy for the mother liquor to denature and grow moss due to long-term storage, affecting the growth of the plant.

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0047] like Figures 1 to 11 As shown, the preparation method of the Clivia culture matrix of the present invention comprises the following steps:

[0048] S1: uniformly mix the carrier powder and the nutrient agent to form a culture medium;

[0049] S2: Add an appropriate amount of thickener to the culture medium, extrude and granulate the culture medium to make it into nutrient masterbatch;

[0050] S3: adding the nutrient masterbatch to the cultivation device, and using the cultivation device to quantitatively mix the nutrient masterbatch into the culture solution, so that the nutrient masterbatch dissolves and disintegrates in the culture solution to form a culture matrix or nutrient solution;

[0051] The nutrient comprises a plurality of components, which are mixed uniformly with each other and then mixed with a carrier powder, wherein the carrier powder is one or more of straw powder, corn cob powder, sawdust, and wood chips;

[0052] When the culture medium is granulated, a connecting line is placed, and the nutrient masterbatch is evenly and independently distributed on the connecting line;

[0053] The thickener is one or more of hydroxymethyl cellulose, hydroxyethyl cellulose, starch, and natural clay;

[0054] The culture solution is sterile water added with a bactericide and plant growth hormone;

[0055] The nutrient comprises the following ingredients in parts by weight: 5-10 parts of calcium nitrate, 5-8 parts of urea, 2-3 parts of potassium dihydrogen phosphate, 5-6 parts of magnesium sulfate, 1.5-2 parts of potassium sulfate, 3-4 parts of ammonium phosphate, 0.15-0.3 parts of ferrous sulfate, 0.2-0.4 parts of disodium edetate, 0.04-0.08 parts of manganese sulfate, 0.05-0.07 parts of boric acid, 0.01-0.02 parts of copper sulfate, 0.01-0.02 parts of zinc sulfate, 0.03-0.04 parts of ammonium molybdate, and 0.01-0.05 parts of thulium nitrate;

[0056] The nutrient agent and carrier powder are mixed to form a culture medium, and the culture medium is granulated to obtain a nutrient masterbatch. After that, the nutrient masterbatch is evenly mixed into the culture medium through a cultivation device to form a nutrient solution, thereby converting the common liquid nutrient solution into a solid nutrient masterbatch, which is convenient for the preparation, use and storage of the nutrient solution, and avoids the prepared liquid nutrient solution from being unable to withstand storage, resulting in precipitation, crystallization, denaturation, and contamination and deterioration of the liquid nutrient solution by pathogens;

[0057] At the same time, when the culture medium is granulated, the connecting line is placed on the mold so that the culture medium is directly attached to the connecting line after being extruded and formed, and the nutrient masterbatch is evenly distributed on the connecting line, so that when the nutrient masterbatch is subsequently added to the culture solution to form the nutrient solution, it is convenient to add the nutrient masterbatch and accurately control the amount of the nutrient masterbatch added, thereby ensuring that the concentration of the nutrient solution in the cultivation device changes accurately, avoiding too much or too little addition of nutrient masterbatch, making the concentration of the nutrient solution unstable and unsuitable, resulting in poor growth or death of the cultivated Clivia plant 22.

[0058] As an embodiment of the present invention, the carrier powder is carbonized in advance;

[0059] The carrier powder is carbonized to increase the porosity of the carrier powder, which facilitates the adsorption of nutrients by the carrier powder, ensures the combination of the carrier powder and the nutrients, and improves the uniformity of the culture medium.

[0060] As an embodiment of the present invention, the nutrient agent is mixed evenly and dissolved in sterile water to form a mother liquid, the carrier powder is added to the mother liquid for soaking, the mother liquid is concentrated and then the carrier powder is added, and the carrier powder and the mother liquid are dried to obtain a culture medium;

[0061] The nutrient agent is dissolved in sterile water to form a mother liquor, so that various nutrients are evenly distributed in the mother liquor. After that, the mother liquor is evaporated and concentrated, and then the carrier powder is added to make the nutrients evenly distributed on the carrier powder. Thus, after the carrier powder and the mother liquor are dried to obtain a culture medium, the nutrients in the culture medium are evenly distributed, avoiding the problem of uneven mixing after directly mixing the nutrient agent and the carrier powder, which makes the nutrients in the culture medium unevenly distributed, and easily leads to the inability to accurately control the concentration change of the nutrient solution when the nutrient masterbatch is subsequently added, causing the cultivated Clivia plant 22 to grow poorly or die;

[0062] At the same time, by soaking the carrier powder in the mother liquor and drying it by evaporation, the carrier powder and the nutrient agent are tightly combined, thereby avoiding separation between the carrier powder and the nutrient agent after granulation to form the nutrient masterbatch, and ensuring the stability of the ingredients in the nutrient masterbatch.

[0063] As an embodiment of the present invention, the cultivation device includes a housing 1, wherein a placement slot 12, a cultivation slot 13 and an installation slot 14 are sequentially arranged in the housing 1 from left to right, and a cover plate 11 is installed on the placement slot 12 and the installation slot 14;

[0064] A planting plate 2 is installed on the culture tank 13, and a Clivia plant 22 is planted on the planting plate 2 through a sponge block 21. A liquid pump 3 is installed in the installation tank 14, and a spray plate 31 is installed on the inner wall of the culture tank 13. The liquid pump 3 delivers the nutrient solution in the culture tank 13 to the spray plate 31;

[0065] A winding wheel 63 and a driving rod 61 are installed on the inner wall of the installation groove 14. A conical driving wheel 62 is installed on the rotating shaft of the winding wheel 63 and the driving rod 61. The conical driving wheels 62 cooperate with each other for transmission. The driving rod 61 is driven by the motor 6. A polished rod 42 is installed in the culture tank 13. A movable plate 4 is slidably installed on the polished rod 42. The movable plate 4 is slidably installed on the polished rod 42. The movable plate 4 is connected to the winding wheel 63 by a pull rope 41, and the pull rope 41 passes through the connecting hole 15 on the inner wall of the shell 1;

[0066] The connection line carrying the nutrient masterbatch is placed in the placement tank 12. The connection line in the placement tank 12 passes through the culture tank 13 and enters the installation tank 14. A partition 141 is installed above the liquid pump 3 in the installation tank 14. The connection line without the nutrient masterbatch in the installation tank 14 is stacked on the partition 141.

[0067] The mounting groove 14 is provided with a pair of squeezing rollers 65 , which are respectively mounted on the driving rod 61 and the mounting shaft. The mounting shaft is fixed to the inner wall of the mounting groove 14 , and the connecting line passes between the two squeezing rollers 65 .

[0068] An electromagnet 64 is mounted on the inner wall of the mounting groove 14, and a connecting plate 641 is rotatably mounted on the drive rod 61. The electromagnet 64 and the connecting plate 641 are connected to each other. When the electromagnet 64 is actuated, the drive rod 61 is driven to move axially. When the electromagnet 64 is actuated, the two conical drive wheels 62 cooperate with each other for transmission.

[0069] When cultivating Clivia, the controller controls the motor 6 to operate, causing the driving rod 61 to rotate, thereby driving the squeezing roller 65 to rotate, causing the connecting wire between the two squeezing rollers 65 to be pulled and pulled, causing the connecting wire that has lost the nutrient masterbatch to be pulled and stacked on the partition 141 in the installation groove 14;

[0070] At the same time, when the connecting wire is pulled and pulled, the connecting wire carrying the nutrient masterbatch stacked in the placement tank 12 will penetrate into the culture tank 13, and the nutrient masterbatch will be immersed in the culture solution in the culture tank 13. After the nutrient masterbatch gradually disintegrates, the nutrient agent will be mixed into the culture solution to form a nutrient solution.

[0071] At the same time, a sensor is provided in the culture tank 13 to detect the concentration data of the nutrient solution, so that the controller controls the operation of the motor 6 according to the concentration data of the nutrient solution, so that the motor 6 discontinuously pulls the connecting line, ensuring that the nutrient masterbatch carried on the connecting line can be fully and long immersed in the culture solution, so that the nutrient masterbatch is fully dissolved and disintegrated to form a nutrient solution, effectively avoiding the nutrient masterbatch soaking time being too short and failing to disintegrate in time to form a nutrient solution, resulting in insufficient nutrient solution concentration or uneven distribution of the nutrient solution in the culture tank 13, affecting the normal growth of the Clivia plant 22;

[0072] At the same time, the lower end of the root system of the Clivia plant 22 in the culture tank 13 will be located on the movable plate 4, so that the lower end of the root system and the movable plate 4 are immersed in the nutrient solution, while the upper end or the middle upper end of the root system is exposed to the air. At this time, the controller controls the liquid pump 3 to operate, and the nutrient solution in the culture tank 13 is sucked and transported to the spray plate 31 through the pipeline, so that the nutrients are sprayed out from the spray plate 31 to form an aerosol, thereby simultaneously performing hydroponics and aerosol cultivation on the Clivia plant 22. At the same time, the controller controls the operation of the electromagnet 64 according to the set interval or cycle. When the electromagnet 64 is in action, it drives the drive rod 61 to move axially through the connecting plate 641, so that the conical drive wheel 62 on the drive rod 61 moves toward the conical drive wheel 6 on the rotating shaft of the winding wheel 63. 2 is close to each other, so that the two conical driving wheels 62 contact and cooperate with each other and start to transmit, so that the winding wheel 63 starts to rotate, and the pull rope 41 is wound, so that the movable plate 4 in the culture tank 13 starts to move upward along the light rod 42, and finally the movable plate 4 and the lower end of the root system of the Clivia plant 22 on the movable plate 4 move upward and are separated from the immersion in the nutrient solution. In this process, the lower end of the root system is immersed in the nutrient solution and the upper end of the root system is surrounded by the mist, which can have the advantages of both hydroponics and aeroponics, and avoid the adverse effects of power outages on the mist. In addition, the movable plate 4 moves upward, driving the lower part of the root system to separate from the nutrient solution together, and can further avoid the problem of root rot caused by the root system being immersed in the liquid for a long time during hydroponics, thereby ensuring that the Clivia is in a good growth state.

[0073] As an embodiment of the present invention, the upper surface of the movable plate 4 is convex upward, and vertical rods 43 are evenly distributed on the upper surface of the movable plate 4;

[0074] Since the upper surface of the movable plate 4 is convex upward, after the movable plate 4 moves upward to above the liquid level, the nutrient solution attached to the upper surface of the movable plate 4 can slide off quickly, thereby preventing the nutrient solution from accumulating on the movable plate 4 and affecting the degree to which the lower end of the root system is separated from the nutrient solution. At the same time, since there are no holes on the upper surface of the movable plate 4, it can also prevent the roots of the Clivia plant 22 from passing through the holes, resulting in damage to the roots of the Clivia plant 22 when the Clivia plant 22 is transplanted or when the movable plate 4 moves up and down;

[0075] At the same time, the lower end of the root system of the Clivia plant 22 is located on the movable plate 4, and a vertical rod 43 is provided on the movable plate 4, which can restrict and fix the root system of the Clivia plant 22, thereby preventing the lower end of the root system of the Clivia plant 22 from being impacted by the nutrient solution when the movable plate 4 rises from the nutrient solution or is re-immersed in the nutrient solution, causing a large swing or shake, causing damage to the root system or causing the root system to fall into the gap between the movable plate 4 and the inner wall of the culture tank 13, resulting in the lower end of the root system being unable to separate from the nutrient solution for a period of time as the movable plate 4 moves upward.

[0076] As an embodiment of the present invention, a fixed block 5 is installed in the culture tank 13, and the fixed block 5 is slidably installed on the polished rod 42. The fixed block 5 moves synchronously with the movable block, and the connecting line in the culture tank 13 is located below the fixed block 5;

[0077] A collecting groove 51 is formed on the surface of the fixed block 5. A bell-shaped cover 52 is mounted on the inner wall of the collecting groove 51. A gap exists between the lower end of the bell-shaped cover 52 and the bottom surface of the collecting groove 51. A siphon tube 53 is mounted in the collecting groove 51. The upper end of the siphon tube 53 is located in the bell-shaped cover 52. A gap exists between the upper end of the siphon tube 53 and the top surface of the bell-shaped cover 52.

[0078] The movable plate 4 and the fixed block 5 are both slidably mounted on the light rod 42, and the movable plate 4 and the fixed block 5 are connected to each other by a support rod, so that the movable plate 4 and the fixed block 5 move synchronously, so that when the movable plate 4 moves upward, the fixed block 5 will also move upward. At this time, the fixed block 5 rises from below the liquid surface, and the collecting tank 51 on the fixed block 5 will be filled with nutrient solution. Therefore, in the process of the fixed block 5 moving upward, the liquid in the collecting tank 51 will be emptied by the suction force generated by the siphon 53, and the liquid extracted by the siphon 53 will impact the nutrient solution in the culture tank 13, so that the nutrient solution in the culture tank 13 circulates, thereby promoting the uniform distribution of the nutrient solution in the culture tank 13, and avoiding that the nutrients released after the disintegration of the nutrient masterbatch cannot be evenly distributed or are absorbed by the Clivia plant 22 to the nutrient solution components, resulting in different concentrations of nutrient solution in different places, thereby affecting the cultivation of Clivia;

[0079] At the same time, in the early stage of planting the Clivia plant 22 and when the root system of the Clivia plant 22 is relatively short, the moving distance of the movable plate 4 and the fixed block 5 is relatively short, and it is easy for the movable plate 4 to reach above the liquid surface while the fixed block 5 is still below the liquid surface. At this time, the movement of the fixed block 5 in the nutrient solution will stir the nutrient solution, promote the flow of the nutrient solution in the culture tank 13, and make the nutrient solution evenly distributed;

[0080] At the same time, by promoting the circulation of the nutrient solution in the culture tank 13, the precipitation, crystallization and denaturation of the nutrient solution can be avoided.

[0081] As an embodiment of the present invention, a baffle 131 is provided on the bottom surface of the culture tank 13, and the outlet of the lower end of the siphon tube 53 is aligned with the baffle 131. The baffle 131 and the siphon tube 53 are respectively located at the two ends of the culture tank 13, and the baffle 131 is provided with an arc surface on the side facing the siphon tube 53.

[0082] When the fixed block 5 moves upward away from the liquid surface, the liquid in the collecting tank 51 will be drawn out and flow downward under the action of the siphon tube 53 to produce an impact. In this process, the liquid flow rushing out of the siphon tube 53 will impact the baffle 131. The baffle 131 guides the liquid flow, causing the liquid flow to circulate in the culture tank 13, promoting the circulation of the nutrient solution in the culture tank 13, and avoiding the dead corners of the nutrient solution in the culture tank 13 when it circulates, resulting in areas of uneven distribution of the nutrient solution, affecting the cultivation of Clivia.

[0083] As an embodiment of the present invention, the surfaces of the components in the culture tank 13 are covered with a hydrophobic coating;

[0084] When the aerosol sprayed from the spray plate 31 contacts the surfaces of the components in the culture tank 13, it reduces the adhesion of water droplets and promotes the water droplets to slide back into the nutrient solution as quickly as possible. At the same time, the hydrophobic coating can also reduce the adhesion of the nutrient solution on the inner wall of the culture tank 13, making the inner wall of the culture tank 13 above the liquid surface relatively dry and clean.

[0085] The specific workflow is as follows:

[0086] The nutrient agent and carrier powder are mixed to form a culture medium, and the culture medium is granulated to obtain a nutrient masterbatch. After that, the nutrient masterbatch is evenly mixed into the culture medium through a cultivation device to form a nutrient solution, so that the common liquid nutrient solution is converted into a solid nutrient masterbatch, which is convenient for the preparation, use and storage of the nutrient solution;

[0087] At the same time, when the culture medium is granulated, the connecting line is placed on the mold so that the culture medium is directly attached to the connecting line after being extruded and the nutrient masterbatch is evenly distributed on the connecting line;

[0088] Carrying out carbonization treatment on the carrier powder to increase the porosity within the carrier powder;

[0089] The nutrient agent is dissolved in sterile water to form a mother liquid, so that various nutrients are evenly distributed in the mother liquid. After that, the mother liquid is evaporated and concentrated, and then added into the carrier powder, so that the nutrients are evenly distributed on the carrier powder. After the carrier powder and the mother liquid are dried to obtain a culture medium, the nutrients in the culture medium are evenly distributed, and the carrier powder and the nutrient agent are tightly combined.

[0090] When cultivating Clivia, the controller controls the motor 6 to operate, causing the driving rod 61 to rotate, thereby driving the squeezing roller 65 to rotate, causing the connecting wire between the two squeezing rollers 65 to be pulled and pulled, causing the connecting wire that has lost the nutrient masterbatch to be pulled and stacked on the partition 141 in the installation groove 14;

[0091] At the same time, when the connecting wire is pulled and pulled, the connecting wire carrying the nutrient masterbatch stacked in the placement tank 12 will penetrate into the culture tank 13, and the nutrient masterbatch will be immersed in the culture solution in the culture tank 13. After the nutrient masterbatch gradually disintegrates, the nutrient agent will be mixed into the culture solution to form a nutrient solution.

[0092] At the same time, a sensor is provided in the culture tank 13 to detect the concentration data of the nutrient solution, so that the controller controls the operation of the motor 6 according to the concentration data of the nutrient solution, so that the motor 6 pulls the connecting line discontinuously;

[0093] At the same time, the lower end of the root system of the Clivia plant 22 in the culture tank 13 will be located on the movable plate 4, so that the lower end of the root system and the movable plate 4 are immersed in the nutrient solution, while the upper end or the middle upper end of the root system is exposed to the air. At this time, the controller controls the liquid pump 3 to operate, and the nutrient solution in the culture tank 13 is sucked and transported to the spray plate 31 through the pipeline, so that the nutrients are sprayed out from the spray plate 31 to form an aerosol, thereby simultaneously performing hydroponics and aerosol cultivation on the Clivia plant 22. At the same time, the controller will control the operation of the electromagnet 64 according to the set interval or cycle. When the electromagnet 64 is in action, it will drive the drive rod 61 to move axially through the connecting plate 641, so that the conical drive wheel 62 on the drive rod 61 is toward the rotating shaft of the winding wheel 63. The conical driving wheels 62 on the upper and lower parts are brought close to each other, so that the two conical driving wheels 62 contact and cooperate with each other and start to transmit, so that the winding wheel 63 starts to rotate, and the pull rope 41 is wound, so that the movable plate 4 in the culture tank 13 starts to move upward along the light rod 42, and finally the movable plate 4 and the lower ends of the roots of the Clivia plants 22 on the movable plate 4 move upward and are out of the immersion of the nutrient solution. In this process, the lower ends of the roots are immersed in the nutrient solution and the upper ends of the roots are surrounded by the mist, which has the advantages of both hydroponics and aeroponics, avoiding the adverse effects of power outages on the mist. In addition, the movable plate 4 moves upward, driving the lower parts of the roots to be out of the nutrient solution together, which can further avoid the problem of root rot caused by the roots being immersed in the liquid for a long time during hydroponics.

[0094] Since the upper surface of the movable plate 4 is convex upward, after the movable plate 4 moves upward to above the liquid level, the nutrient solution attached to the upper surface of the movable plate 4 can slide down quickly;

[0095] At the same time, the lower end of the root system of the Clivia plant 22 is located on the movable plate 4, and a vertical rod 43 is provided on the movable plate 4 to restrict and fix the root system of the Clivia plant 22;

[0096] The movable plate 4 and the fixed block 5 are both slidably mounted on the polished rod 42. The movable plate 4 and the fixed block 5 are connected to each other by a support rod, so that the movable plate 4 and the fixed block 5 can move synchronously. When the movable plate 4 moves upward, the fixed block 5 will also move upward. At this time, the fixed block 5 rises from below the liquid surface, and the collecting tank 51 on the fixed block 5 will be filled with nutrient solution. Therefore, in the process of the fixed block 5 moving upward, the liquid in the collecting tank 51 will be emptied by the suction force generated by the siphon 53, and the liquid extracted by the siphon 53 will impact the nutrient solution in the culture tank 13, so that the nutrient solution in the culture tank 13 circulates, thereby promoting the uniform distribution of the nutrient solution in the culture tank 13.

[0097] At the same time, in the early stage of planting the Clivia plant 22 and when the root system of the Clivia plant 22 is relatively short, the moving distance of the movable plate 4 and the fixed block 5 is relatively short, and it is easy for the movable plate 4 to reach above the liquid surface while the fixed block 5 is still below the liquid surface. At this time, the movement of the fixed block 5 in the nutrient solution will stir the nutrient solution, promote the flow of the nutrient solution in the culture tank 13, and make the nutrient solution evenly distributed;

[0098] At the same time, by promoting the circulation of the nutrient solution in the culture tank 13, the precipitation, crystallization and denaturation of the nutrient solution are avoided;

[0099] When the fixed block 5 moves upward away from the liquid surface, the liquid in the collecting tank 51 is drawn out by the siphon 53 and flows downward, generating an impact. During this process, the liquid flow rushing out of the siphon 53 impacts the baffle 131. The baffle 131 guides the liquid flow, causing the liquid flow to circulate in the culture tank 13, thereby promoting the circulation of the nutrient solution in the culture tank 13.

[0100] When the aerosol sprayed from the spray plate 31 contacts the surfaces of the components in the culture tank 13, it reduces the adhesion of water droplets and promotes the water droplets to slide back into the nutrient solution as quickly as possible. At the same time, the hydrophobic coating can also reduce the adhesion of the nutrient solution on the inner wall of the culture tank 13, making the inner wall of the culture tank 13 above the liquid surface relatively dry and clean.
