Description

Technical Field

[0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a pepper seedling cultivation device. Background Art

[0002] Pepper seedling technology refers to a series of cultivation, management and technical measures adopted to obtain high-quality and healthy pepper seedlings. It is a very important link in pepper production, which directly affects the growth and development of the plant and the final yield. In the seedling sowing stage, it is necessary to use nutrient soil, peat soil, vermiculite and other seedling substrates, and ensure that they are loose and breathable to promote root development. After the seedlings emerge from the soil, apply diluted nutrient solution in time to provide the necessary nutrients and promote growth. When the seedlings reach a certain height (generally 15-20 cm) and have a good root system, they can be transplanted.

[0003] The high-quality seedlings obtained through seedling cultivation can ensure a high survival rate, thereby increasing the overall yield of peppers. In the prior art, seedling boxes are often used for seedling cultivation. Seedling cultivation in seedling boxes is usually carried out in a greenhouse, a shade shed or a temperature-controlled environment. The environment in the seedling box is controllable, which can ensure the germination rate of seeds and the healthy growth of seedlings. Existing seedling box seedling cultivation has the advantages of high survival rate and convenient management compared to nursery seedling cultivation. Therefore, seedling boxes are often used for seedling cultivation in small and medium-sized plantings. There is a problem of difficulty in irrigation when using traditional seedling boxes for seedling cultivation. Since the seedling boxes are usually small in size, they need to be irrigated and replenished with water frequently. Therefore, frequent irrigation is required, which is time-consuming and labor-intensive.

[0004] A pepper seedling irrigation device is disclosed in the patent with application number CN202321728423.6. This irrigation device includes a water pump, a protective tube and a water supply mechanism. The water pump is connected to the main water pipe above, and the main water pipe is vertically connected to the protective tube. The water supply mechanism is installed inside the protective tube, and the diversion mechanism is installed on the left side of the water supply mechanism. The pepper seedling irrigation device is equipped with a water supply mechanism, and a nozzle can be used for drip irrigation of peppers. Multiple groups of nozzles are installed, so the drip irrigation area is increased during drip irrigation. This irrigation device will also face the problem of water waste when in use. Since the seedling box body is not large in size, the use of nozzles for irrigation will result in uneven irrigation and water waste. Summary of the invention

[0036] Example:

[0037] A pepper seedling raising device, such as Figure 1As shown, it includes a placement frame 14, a box body 1, a partition 2 and an irrigation mechanism; wherein the box body 1 is arranged on the placement frame 14, the partition 2 is arranged in the box body 1 and separates a plurality of seedling troughs 6 in the box body 1; the irrigation mechanism includes a water adding tank 10, a material adding and mixing box 11, a water pump 7, a distribution piece 8, an irrigation pipe 5, and an irrigation head 4; the material adding and mixing box 11 is arranged on the water tank and communicated with the water tank, the water pump 7 is connected to the water tank, and the distribution piece 8 is connected to the outlet of the water pump 7; a plurality of irrigation pipes 5 are connected to the distribution piece 8, and the irrigation heads 4 are arranged on both sides of the irrigation pipe 5, the number of the irrigation heads 4 matches the number of the seedling troughs 6 and each irrigation head 4 corresponds to a seedling trough 6.

[0038] Among them, the placement frame 14 is used to support the box body 1 and isolate the box body 1 from the ground, so as to facilitate drainage and ventilation at the bottom of the box body 1, ensure the air permeability of the soil in the box body 1, and effectively prevent root rot. The separator 2 separates a number of grid-shaped seedling troughs 6 in the box body 1, and can separate the seedlings when raising pepper seedlings, so as to facilitate division when transplanting. The feeding mixing box 11 is used to put nutrients into the water tank. In addition, a switch is provided between the feeding mixing box 11 and the water adding box 10. Through this design, the nutrients can be prepared in advance and put into the feeding mixing box 11. When irrigation is performed, the switch is turned on to put the nutrients in the feeding mixing box 11 into the mixing box. Specifically, when in use, the water pump 7 pumps the water in the water adding box 10 into the distribution part 8, and the water in the distribution part 8 flows into the irrigation pipe 5 respectively, and the water in the irrigation pipe 5 flows into each seedling trough 6 through the irrigation head 4. In this way, automatic irrigation can be carried out, and at the same time, this irrigation method can also achieve the effect of water saving.

[0039] In a preferred embodiment, if Figure 3 As shown, a mounting step 20 is provided in the placement frame 14, and the box body 1 is placed on the mounting step 20. The mounting step 20 provides a solid and stable support surface for the box body 1, so that the box body 1 can be stably placed on the placement frame 14, and can effectively prevent the box body 1 from detaching from the prevention frame. In addition, in this way, the box body 1 can be easily replaced.

[0040] In a preferred embodiment, if Figure 3As shown, the bottom of the box body 1 is provided with a breathable bottom plate 16, and the breathable bottom plate 16 is provided with air holes 17; the installation step 20 is provided with a filter baffle 18, and the filter baffle 18 is provided with a filter hole 21. The breathable bottom plate 16 at the bottom of the box body 1 and the air holes 17 on the breathable bottom plate 16 enable the circulation of air and water. The filter baffle 18 is used to filter impurities and prevent soil and other impurities from flowing away with water. The purpose of this design is to ensure the air permeability of the soil in the box body 1 and the effectiveness of water discharge, while preventing the influence of particulate matter and impurities in the soil on the drainage system. Specifically, the design of the breathable bottom plate 16 and its air holes 17 ensures that the inside of the box body 1 can maintain good air circulation, which is conducive to the breathing and development of the root system and reduces the root damage caused by lack of oxygen. The air holes 17 allow excess water to be quickly discharged from the box body 1, prevent root rot caused by excessive water, and help maintain appropriate soil moisture. The air permeability and filtration mechanism work together to help maintain the structure and health of the soil, promote the normal growth of plant roots, and improve the survival rate of seedlings. The air permeability design helps to evenly distribute water and nutrients, allowing the roots of seedlings to better absorb the necessary water and nutrients, promoting their healthy growth.

[0041] In a preferred embodiment, Figure 2 As shown, a water guide plate 19 is provided on one side of the placement frame 14 near the bottom, and the top surface of the water guide plate 19 is inclined. A water outlet 22 is provided on the side of the placement frame 14 near the drinking plate that is inclined downward, and the drinking plate is used to guide water to the water outlet 22. Further optimized, a water collecting tank 15 is provided outside the placement frame 14, and the water collecting tank 15 is connected to the water outlet 22. Water enters the water tank through the water outlet 22, and the water flowing out of the soil is collected by the water collecting tank 15. The inclined design of the water guide plate 19 ensures that the water flow can be smoothly guided to the water outlet 22, reducing the retention of water in the placement frame 14. The setting of the water collecting tank 15 can collect the water flowing out through the water outlet 22, which is convenient for subsequent reuse of water and reduces the waste of water resources. After the water collecting tank 15 collects the discharged water, it can test the discharged water to understand the moisture and nutrient loss of the soil, provide data support for fertilizer management and water regulation, and promote scientific management. In addition, through this system, the water in the water collection tank 15 can be used for irrigation after being treated, forming a virtuous water cycle, which is conducive to the efficient use of resources.

[0042] In a preferred embodiment, Figure 1 As shown, a water outlet 3 is provided on one side of the water collecting tank 15, and a connecting flange is provided on the water outlet 3. The connecting flange can facilitate the water outlet 3 to be connected to the water pipe, so as to conveniently lead away the water collected in the water collecting tank 15. Further optimized, a water inlet 9 is provided on one side of the water adding tank 10, and a connecting flange is provided on the water inlet 9. The design of the connecting flange can facilitate the water inlet 9 to be connected to the water pipe, and water can be added to the water inlet tank through the water pipe.

[0043] In a preferred embodiment, if Figure 1 As shown, the box 1 is provided with carrying handles 13 on both sides. The design of the carrying handles 13 provides a gripping point, so that the user can more easily move and place the box 1 during transportation. The setting of the handles can effectively reduce the risk of accidental slipping, increase the stability during transportation, and ensure the safety of the user during operation. During the transportation process, providing a reasonable holding position can prevent the soil and plants from tilting or shaking, ensure that the soil will not fall easily, and protect the integrity of the seedlings and reduce damage.

[0044] In a preferred embodiment, the water pump 7 is a diaphragm pump. With the help of the diaphragm pump, the user can flexibly adjust the water flow and pressure according to the needs of different stages, such as irrigation frequency and water volume, to ensure uniform irrigation.

[0045] In a preferred embodiment, if Figure 4 As shown, a stirring motor 12 is arranged outside the water tank 10, and a stirring shaft 23 is rotatably connected inside the water tank 10, and a plurality of stirring blades 24 are evenly arranged outside the stirring shaft 23; one side of the stirring shaft 23 passes through the side wall of the water tank 10 and is fixedly connected to the output shaft of the stirring motor 12. The stirring blades 24 are evenly arranged on the stirring shaft 23, which can fully stir the water and the nutrient agent, ensure that the components are evenly mixed, avoid precipitation or stratification of the nutrients, and help the plants to absorb them evenly. The power of the stirring motor 12 is directly transmitted to the stirring shaft 23, so that the stirring effect is efficient and stable, thereby improving the working efficiency of the overall equipment.

[0046] A pepper seedling raising method, characterized in that it comprises the following steps:

[0047] S1, soak pepper seeds in 0.7%-1.3% potassium permanganate solution for 8-12 minutes, and rinse with clean water after soaking; soak the seeds in warm water at 25-30°C for 8-12 hours, take them out and wrap them with wet cloth, place them in an environment at 25-30°C for germination, rinse them with warm water once a day, and prepare for sowing after more than 50% of the seeds turn white;

[0048] When using 0.7%-1.3% potassium permanganate solution to soak pepper seeds, a clean and suitable container should be selected, such as a glass beaker or a plastic basin, to ensure that the solution completely covers the seeds. In this embodiment, a 1% potassium permanganate solution is used. The seeds can be properly stirred during the soaking process so that all sides can fully contact the potassium permanganate solution to ensure a more uniform disinfection and sterilization effect. After the soaking is completed, rinse the seeds with running water. The rinsing time is recommended to be about 3-5 minutes to thoroughly remove the potassium permanganate solution remaining on the surface of the seeds to avoid its adverse effects on subsequent seed germination.

[0049] When soaking the seeds in warm water at 25-30℃, the water temperature can be accurately measured and controlled using a thermometer to ensure that the water temperature remains within this suitable range. During the soaking period, the seeds can also be gently stirred every 1-2 hours to make the seeds heat more evenly and facilitate full water absorption. After taking out the seeds and wrapping them with a wet cloth, place them in a constant temperature incubator or a special germination room where the temperature can be precisely controlled at 25-30℃ for germination. When rinsing with warm water every day, the water temperature must also be maintained at around 25-30℃, and the rinsing action should be gentle to avoid damaging the seeds that have begun to germinate. When more than 50% of the seeds are observed to be white, that is, when you can see that the radicle of the seeds breaks through the seed coat to reveal the white part, you can prepare for sowing. At this time, the sowing operation should be carried out as soon as possible to prevent the seeds from being exposed to the external environment for a long time, resulting in water loss and other situations that affect the germination rate.

[0050] S2, using peat, perlite and vermiculite in a ratio of 3:1:1 to prepare a matrix, using any one of carbendazim, formalin solution and high-temperature steam to disinfect the matrix; filling the matrix into the seedling tank 6;

[0051] When peat, perlite and vermiculite are mixed in a ratio of 3:1:1, these raw materials should be screened first to remove large impurities, stones, etc. that may exist in them. Screening can be done with a sieve, such as a sieve with a pore size of 2-5 mm, to ensure that the texture of the raw materials is relatively uniform. The screened raw materials should be fully mixed according to the proportion. They can be stirred manually or with a small mixer. The stirring time should be controlled within 5-10 minutes to ensure that the three are mixed evenly to form a matrix with loose texture, good air permeability and suitable water and fertilizer retention capacity.

[0052] If you choose carbendazim for disinfection, you can prepare it according to the concentration required by the instructions. The commonly used concentration is 50% wettable powder diluted 800-1000 times. Soak the substrate in the prepared carbendazim solution for about 1-2 hours, then remove the substrate and place it in a well-ventilated and shaded place to dry, so that excess water in the substrate can be dissipated to avoid water accumulation during subsequent sowing that affects seed germination.

[0053] When using formalin solution, it is usually diluted into a solution of about 40%, and then 200-300 ml of formalin is used per cubic meter of substrate, and it is evenly sprayed on the substrate. The substrate is then sealed with plastic film for 2-3 days to allow the formalin to fully evaporate and sterilize. After sealing, the film is removed and the substrate is dried for about 7-10 days. During this period, the substrate should be turned over several times to ensure that the formalin residue is completely evaporated to prevent poisoning of the seedlings.

[0054] When high-temperature steam sterilization is used, the substrate is placed in a special steam sterilization device, the steam temperature is controlled at 80-100°C, and the steam is continuously steamed for 2-3 hours to kill harmful organisms such as pathogens, insect eggs and weed seeds in the substrate. After the sterilization is completed, the substrate temperature is naturally reduced to room temperature before being filled into the seedling raising tank 6 to avoid high temperature scalding the seeds.

[0055] S3, sow 1-2 white seeds in each seedling trough 6, cover with 0.5-1 cm thick matrix, and gently compact; water thoroughly after sowing to keep the matrix moist;

[0056] When sowing 1-2 white seeds in each seedling raising groove 6, first use tools such as fingers or small wooden sticks to gently press out small pits on the matrix of seedling raising groove 6, the small pit depth is controlled at about 0.5-1 centimetre, then the white seeds are put into the pit, and then the matrix of 0.5-1 centimetre thickness is covered, and the palm of the hand or small wooden board etc. are used to compact gently after covering the matrix, and it is noted that the compaction strength is moderate, too light may cause seeds to contact loosely with the matrix, which is unfavorable for the seed water absorption and germination, and too heavy may affect the seed to break the ground and emerge. When watering after sowing, a fine-mouthed watering can or a spraying device will be adopted to water, and it is avoided that water flows through and runs away the seeds or causes the matrix surface to be uneven. Watering will be poured until there is water seepage at the bottom of the seedling raising groove 6, and it is guaranteed that the whole matrix layer can fully absorb moisture, and it is necessary to pay attention to the dry and wet situation of the matrix afterwards, and the humidity can be felt by inserting the matrix surface layer through a finger, and once it is found that the matrix surface begins to dry, a small amount of water will be replenished in time, and the matrix moistening state is kept, and good moisture conditions are created for seed germination.

[0057] S4, during the seedling stage, the daytime temperature is maintained at 25-30℃, the nighttime temperature is maintained at 15-20℃, the daily light hours are maintained at 12-14 hours, and the air humidity is maintained at 60%-70%;

[0058] During the seedling emergence stage, the daytime temperature is maintained at 25-30℃. Temperature control equipment, such as intelligent temperature controllers, can be installed in the seedling raising device or greenhouse to accurately adjust the temperature. When the temperature is higher than the set upper limit, ventilation and cooling equipment, such as exhaust fans and vents, can be automatically turned on; when the temperature is lower than the set lower limit, heating equipment, such as heaters and geothermal lines, can be used to increase the temperature. The nighttime temperature is maintained at 15-20℃, and temperature control equipment is also used for regulation. At night, attention should be paid to insulation measures, such as closing the doors and windows of the seedling raising facilities and covering them with insulation curtains.

[0059] The light intensity is maintained at 12-14 hours per day, which can be achieved by combining natural light with artificial light. In the case of insufficient light, such as cloudy days and short daylight hours in winter, turn on plant light supplementary lights, such as LED plant light supplementary lights, and arrange them at a power of about 20-30 watts per square meter. The height of the supplementary light is controlled at about 30-50 cm from the seedlings to ensure uniform light intensity. The air humidity is maintained at 60-70%, which can be monitored in real time by placing a hygrometer in the nursery facility. When the humidity is low, use a spray device to spray water appropriately to increase the air humidity; when the humidity is high, increase the ventilation to reduce the humidity to avoid diseases caused by excessive humidity.

[0060] S5, after emergence, the daytime temperature is maintained at 20-25°C, and the nighttime temperature is maintained at 13-17°C; after emergence, thinning is performed, one strong seedling is retained in each seedling trough 6, and the seedling trough 6 lacking seedlings is supplemented;

[0061] After emergence, the daytime temperature is maintained at 20-25°C, and the temperature control equipment is also used for precise control. According to the actual temperature conditions, ventilation, shading or heating measures are adjusted in time. The nighttime temperature is maintained at 13-17°C, and the nighttime insulation work is done well. For example, the thickness of the insulation curtain can be thickened to prevent the nighttime temperature from being too low and affecting the growth of seedlings. When thinning out after emergence, the growth of seedlings in each seedling trough 6 should be carefully observed, and seedlings with strong growth, developed root system, dark green leaves and no pests and diseases should be selected to stay. Weak, leggy or seedlings with signs of pests and diseases should be removed in time, and only one strong seedling should be left in each seedling trough 6. For seedling troughs 6 that are missing seedlings, spare seedlings that grow strong and have similar growth in the same period should be selected for seedling supplementation. When supplementing seedlings, be careful to minimize the disturbance of the roots and substrate of the surrounding seedlings. After supplementing seedlings, a small amount of water should be poured in time to help the supplemented seedlings adapt to the new environment as soon as possible and resume growth.

[0062] S6. After the seedlings grow 2-3 true leaves, apply thin liquid fertilizer once a week. After the seedlings grow 2-3 true leaves, apply thin liquid fertilizer once a week. Thin liquid fertilizer can be made from special fertilizers for vegetable seedlings and diluted according to the instructions. The general dilution multiple is about 500-800 times. When applying fertilizer, use tools such as a spray bottle or fertilizer gun to spray the liquid fertilizer evenly on the substrate around the roots of the seedlings to avoid direct contact between the liquid fertilizer and the leaves of the seedlings to prevent burns. It is best to choose the morning of a sunny day to apply fertilizer, so that the seedlings can absorb and utilize the fertilizer. After fertilizing, a small amount of water can be applied to promote better penetration of the fertilizer into the substrate and improve the utilization rate of the fertilizer. In a preferred embodiment, the ingredients of the dilute liquid fertilizer, measured by mass fraction, include 1-2 parts of urea, 1-2 parts of potassium dihydrogen phosphate, 1-2 parts of potassium sulfate, and 500 parts of water; when preparing the dilute liquid fertilizer, it can be directly prepared through the water adding tank 10 and fertilized to each seedling trough, by adding each ingredient into the water adding tank 10 and stirring through the stirring shaft 23 and the stirring blade 24 in the water adding tank 10, so as to evenly water and fertilize each seedling trough.

[0063] S7, gradually reduce watering 7-10 days before transplanting, increase ventilation and light, lower the temperature, and enhance the resistance of seedlings to stress; gradually reduce watering 7-10 days before transplanting, and at the beginning, you can appropriately extend the watering interval, such as watering once a day, gradually adjust to watering every 2-3 days, and reduce the amount of water each time, so that the substrate gradually dries up, prompting the roots of the seedlings to grow deeper into the substrate, and enhancing the absorption capacity and resistance of the roots. In terms of increasing ventilation and light, gradually increase the opening of the vents of the seedling facilities, extend the ventilation time, and allow the seedlings to gradually adapt to the external air environment; at the same time, reduce the use of shading facilities, increase the duration of natural light, so that the seedlings can better photosynthesize, accumulate more organic matter, and enhance their own resistance. When lowering the temperature, you can adjust the set temperature of the temperature control equipment and increase ventilation to make the temperature of the seedling environment gradually approach the normal temperature of the outside world. For example, the daytime temperature can be gradually reduced from the original suitable temperature to around 15-20℃, and the nighttime temperature can be reduced to around 10-15℃. Through this seedling hardening process, the seedlings' resistance to stress can be comprehensively improved, making them fully prepared for growth after planting.

[0064] S8, seedlings can be transplanted when they have 5-6 true leaves, plant height of 15-20 cm, and stem thickness of 0.4-0.5 cm. Seedlings can be transplanted when they have 5-6 true leaves, plant height of 15-20 cm, and stem thickness of 0.4-0.5 cm. When judging these indicators, use measuring tools such as a ruler to accurately measure plant height and stem thickness, and count the number of true leaves carefully to ensure that the seedlings meet the standard conditions for transplanting. At the same time, a comprehensive disease and insect pest inspection should be carried out on the seedlings before transplanting to ensure that the transplanted seedlings are healthy and free of disease and insect pests, so that they can grow and develop better after transplanting, and improve the survival rate of transplanting and the subsequent yield and quality of peppers.
