Description

Technical Field

[0001] This invention relates to the field of agricultural breeding technology, specifically to a potato seed tuber raising device. Background Technology

[0002] Potatoes are a staple food product, widely cultivated due to their nutritional value, ease of planting, and high yield. However, due to their unique characteristics as self-pollinating crops, most varieties have low flowering rates or difficulty in seed production, making seed acquisition extremely challenging. Therefore, seedling cultivation is necessary.

[0003] Currently, when cultivating potato seedlings, virus-free seed potatoes are first selected. Virus-free seed potatoes have high yield and good quality. They are then cut into pieces, and after sprouting, the sprouted seed potato seedlings are planted. The bottom buds of potato seed potatoes are connected to the rootstock and are prone to containing more plant pathogens, resulting in low yield. However, the buds at the waist and top have better sprouting quality. Therefore, when cutting potato seed potatoes into pieces for sprouting, the waist and top buds are cut into multiple smaller pieces along the buds to encourage more sprouting. Ordinary farmers usually plant potato seed potatoes as soon as they sprout after cutting them into pieces. However, large-scale agricultural producers usually need to cultivate potato seedlings before planting. Some use greenhouses for sprouting, while others use seedbeds. Greenhouse cultivation requires a greenhouse structure, while seedbed sprouting is more convenient and easier to manage. When cultivating potato seed tubers in a seedbed, the cut seed tuber pieces are stacked on the seedbed and then covered with a thin film to facilitate rapid germination. However, in current seedbed cultivation, because the potato pieces are stacked on the seedbed and covered with sand, if ventilation or nutrient solution is not provided in time, or if ventilation is excessive, the potato pieces are prone to rotting and root rot due to excessive ventilation and humidity. Insufficient ventilation can also cause the sand and soil to become too dry, hindering seed tuber germination. Furthermore, since multiple potato pieces are stacked on the seedbed, if one piece rots, it can spread to other pieces, contaminating the entire seedbed soil. Therefore, we propose a potato seed tuber cultivation device. Summary of the Invention

[0004] The purpose of this invention is to provide a potato seed tuber raising device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a potato seed tuber raising device, comprising a seedling bed, wherein the seedling bed is provided with multiple transverse partitions and longitudinal partitions, and the transverse partitions and longitudinal partitions form multiple seedling single chambers, the bottom of the seedling single chamber is provided with an insertion groove for storing nutrient solution, and a seedling cylinder is placed on the top of the insertion groove, the inside of the seedling cylinder is distributed with three layers of media of different densities, a skeleton layer is installed on the seedling bed, and the skeleton layer is covered with a thin film; ventilation channels are provided on the transverse partitions and longitudinal partitions, and ventilation components are provided on the outside of the seedling bed, and the ventilation components are connected to the ventilation channels.

[0006] Preferably, both the transverse and longitudinal partitions are provided with upper and lower ventilation channels, and each seedling single chamber has an air vent on its side wall that communicates with the ventilation channel, with the air vent facing the seedling cylinder.

[0007] Preferably, the air vents on the side walls of each seedling single chamber are distributed from low to high.

[0008] Preferably, the seedling tube has a conical structure, the top of the seedling tube is a stable ring, and the bottom of the seedling tube is a cover that fits into the insertion groove. A water-permeable membrane is provided at the internal communication point of the seedling tube covered by the cover. The upper part of the seedling tube has a downward-sloping air inlet, and the lower part of the seedling tube has an upward-sloping air outlet. The diameter of the air inlet is larger than the diameter of the air outlet.

[0009] Preferably, the inside of the seedling tube is provided with an isolation ring platform.

[0010] Preferably, the media layer inside the seedling cylinder consists of a grass particle layer, a fine sand layer, and a coarse sand layer from top to bottom, wherein the fine sand layer is mixed with microbial inoculants.

[0011] Preferably, the skeleton layer is composed of horizontal and vertical skeleton strips, and a fixing plate is installed at the intersection of each horizontal and vertical skeleton strip. A temperature sensing probe is installed at the bottom of the fixing plate. An adjustment seat is installed on the seedling bed, and the skeleton strips are inserted into the adjustment seat.

[0012] Preferably, the ventilation component includes two pairs of ventilation groups, each consisting of two symmetrically installed ventilation bladders on the outer wall of the seedling bed. Each ventilation bladder has two ventilation pipes, one above the other, connected to the ventilation channel. The ventilation bladder connected to the ventilation channel on the transverse partition is the air inlet bladder, and the ventilation bladder connected to the ventilation channel on the longitudinal partition is the air intake bladder.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention creates individual seedling chambers by setting multiple horizontal and vertical plates on the seedling bed. A slot at the bottom of each chamber is used to insert seedling tubes and nutrient solution. Ventilation channels distributed on the horizontal and vertical plates allow for timely gas introduction or absorption into each individual seedling chamber. This helps maintain the gas content within each seedling tube, preventing root rot from excessive ventilation and avoiding dryness and failure to germinate due to insufficient ventilation.

[0015] This invention, by designing a cone-shaped seedling tube, facilitates the concentrated development of the root system along the cone after the potato seed tubers sprout and take root, which is beneficial for the potato seed tubers to develop a strong root system and thus facilitates the absorption of nutrient solution after the potato seed tubers are raised.

[0016] This invention, by installing multiple temperature-sensing probes in the skeleton layer, facilitates timely monitoring of the temperature and humidity in each seedling chamber. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please refer to the attached document. Figure 1 - Appendix Figure 11 This invention provides a technical solution: a potato seed tuber raising device, including a seedbed 1. The seedbed 1 has a rectangular frame structure, and its specific dimensions are customized according to the cultivation requirements. To increase the stability of the seedbed 1, four support columns are fixedly installed at the four corners of the bottom of the seedbed 1. Furthermore, to facilitate adjustment of the height of the seedbed 1, the support columns are telescopic, allowing the height of the seedbed 1 to be adjusted as needed. The seedbed 1 has multiple transverse partitions 2 and longitudinal partitions 3, the distribution of which is shown in the attached figure. Figure 3 and attached Figure 8 As shown, the transverse partition 2 and the longitudinal partition 3 form multiple seedling single chambers 4. The transverse partition 2 and the longitudinal partition 3 are fixed to each other by plates, which are fixed by adhesive or other means. The assembled transverse partition 2 and the longitudinal partition 3 are assembled in the space of the seedling bed 1 by manual or lifting equipment.

[0021] The bottom of the seedling single chamber 4 is equipped with a nutrient solution insertion groove 41. The nutrient solution is for the root system to absorb after the potato seed tubers have rooted. The nutrient solution uses a special root and stem enlargement agent (core components: choline chloride (5%) + naphthaleneacetic acid (0.2%) to promote cell division and elongation, phosphorus (15%) and potassium (20%) to accelerate nutrient transport and starch accumulation, and calcium (4%) and boron (0.5%) to prevent fruit cracking and enhance stress resistance).

[0022] A seedling tube 5 is placed on top of the insertion slot 41. The seedling tube 5 contains three layers of media with different densities. The media layers inside the seedling tube 5 are, from top to bottom, a grass granule layer 57, a fine sand layer 58, and a coarse sand layer 59. The fine sand layer 58 is mixed with oil-based microbial inoculant. The cut potato seed tubers are buried in the fine sand layer 58. The grass granule layer 57 is made by cutting straw into granules and spreading it on top of the fine sand layer 58. This facilitates the breathing and ventilation of the potato seed tubers after sprouting. On the other hand, the grass granule layer 57 can absorb the humid air in the seedling single chamber 4, preventing the environment in the seedling tube 5 from being too humid, thereby preventing the potato seed tubers from rotting after sprouting.

[0023] To ensure the temperature inside the seedbed 1, which is conducive to the germination of potato seed tubers, a skeleton layer 6 is installed on the seedbed 1. The skeleton layer 6 is composed of horizontal and vertical skeleton strips 61. A fixing plate 62 is installed at the intersection of each horizontal and vertical skeleton strip 61, and a temperature sensor 63 is installed at the bottom of the fixing plate 62. An adjustment seat 11 is installed on the seedbed 1, and the skeleton strips 61 are inserted into the adjustment seat 11. During installation, the two ends of the horizontal and vertical skeleton strips 61 are inserted into the adjusting seat 11. According to the height of the skeleton layer 6, the horizontal and vertical skeleton strips 61 are inserted into the adjusting seat 11 to the appropriate depth. Then, the horizontal and vertical skeleton strips 61 are fixed in the position of the adjusting seat 11 by fixing nuts or cable ties. At the same time, a film 7 is covered on the outside of the skeleton layer 6. Under the support of the skeleton layer 6, the film 7 forms a corresponding space. The four sides of the film 7 are pressed onto the seedling bed 1 by objects such as boards and stones. Alternatively, the four corners of the film 7 can be tied to the seedling bed 1. The film 7 is made of transparent plastic film, which is conducive to light or sunlight transmission, thereby promoting the sprouting of potato seed tubers. Ventilation channels 8 are provided on the transverse partition 2 and the longitudinal partition 3. Ventilation components 9 are provided on the outside of the seedling bed 1, and the ventilation components 9 are connected to the ventilation channels 8.

[0024] Both the transverse partition 2 and the longitudinal partition 3 have upper and lower ventilation channels 8, and each seedling single chamber 4 has an air inlet 42 on its side wall that communicates with the ventilation channel 8, with the air inlet 42 facing the seedling cylinder 5. The air inlets 42 on the side wall of each seedling single chamber 4 are distributed from low to high. Each seedling single chamber 4 has four plates. The transverse partition 2 has an air inlet 92, which allows air to enter through the ventilation channel 8 at the bottom of one of the transverse partitions 2 and the ventilation channel 8 at the top of the other transverse partition 2. This allows air to be ventilated from both the bottom and top of each seedling single chamber 4, effectively improving the airflow at the sprouting site of the potato seed tubers.

[0025] The seedling tube 5 has a conical structure. The top of the seedling tube 5 is a stable ring 51, and the bottom of the seedling tube 5 is a cover 52 that cooperates with the insertion groove 41. A water-permeable membrane 53 is provided at the connection between the cover 52 and the inside of the seedling tube 5. The upper part of the seedling tube 5 has a downward-sloping air inlet 54, and the lower part of the seedling tube 5 has an upward-sloping air outlet 55. The diameter of the air inlet 54 is larger than the diameter of the air outlet 55.

[0026] The seedling tube 5 is equipped with an isolation ring platform 56 inside.

[0027] The ventilation component 9 includes two pairs of ventilation groups, each consisting of two symmetrically installed ventilation bags 91 on the outer wall of the seedling bed 1. Each ventilation bag 91 has two ventilation pipes 96, one above the other, connected to the ventilation channel 8. The ventilation bag 91 connected to the ventilation channel 8 on the transverse partition 2 is the inlet bag 92, and the ventilation bag 91 connected to the ventilation channel 8 on the longitudinal partition 3 is the suction bag 93. Both the inlet bag 92 and the suction bag 93 are externally equipped with electromagnetic micro-pumps 94. Temperature signals detected by the temperature sensor 63 are transmitted to the controller of the electromagnetic micro-pump 94. Each seedling single chamber 4 has a telescopic air baffle 43 installed at one location. A fixing frame 95 is installed externally on each ventilation bag 91 and connected to the seedling bed 1.

[0028] In practical use, first, bury the coarse sand layer 59 at the bottom of the seedling cylinder 5, then bury the cut potato seed pieces in the middle layer of the seedling cylinder 5, securing the potato seed pieces with the cut surface facing down and the buds facing up. Then, fill the middle layer of the seedling cylinder 5 with a fine sand layer 58, and finally, lay a layer of straw granules 57 on top of the fine sand layer 58. Install the cover 52 at the bottom of the seedling cylinder 5 into the insertion groove 41 filled with nutrient solution. After all the seedling cylinders 5 in the seedling bed 1 are stacked, lay the horizontal and vertical skeleton strips 6 as needed. The height of the frame layer 6 is determined by inserting the horizontal and vertical frame strips 61 into the adjusting seat 11 to the appropriate depth. Then, the horizontal and vertical frame strips 61 are fixed to the adjusting seat 11 by fixing nuts or cable ties. At the same time, a film 7 is covered on the outside of the frame layer 6. Under the support of the frame layer 6, the film 7 forms a corresponding space. The four sides of the film 7 are pressed onto the seedbed 1 by objects such as boards or stones. Alternatively, the four corners of the film 7 can be tied to the seedbed 1. The film 7 is made of transparent plastic film, which is conducive to light or sunlight transmission, thereby promoting the sprouting of potato seed tubers.

[0029] Because a fixing plate 62 is installed at the intersection of each horizontal and vertical frame strip 61, and a temperature probe 63 is installed at the bottom of the fixing plate 62, the temperature probe 63 is a temperature and humidity probe. (Humidity sensing mechanism: capacitive sensing: the dielectric constant of the polymer material changes with humidity; the capacitance increases when humidity increases (formula: C=C0+k⋅RHC=C0+k⋅RH). resistive sensing: the resistance of humidity-sensitive materials (such as lithium oxide) decreases as humidity increases, and conductivity increases. Synchronous temperature correction is required because humidity is a function of temperature.) Number of measurements is crucial to avoid measurement bias. Temperature sensing mechanisms include: Resistance temperature detectors (RT): The resistance of platinum metal is linearly related to temperature (RT = R0(1+αT)). Thermocouples: Based on the Seebeck effect, temperature difference generates a thermoelectric electromotive force (E = S⋅ΔT). Thermistors: Available in positive / negative temperature coefficient types, requiring calibration to match non-linear changes. Signal processing flow: The original electrical signal is filtered, denoised, amplified, and then converted for output. Output formats include: analog signals. (4–20mA current / 0–10V voltage) Adaptable to industrial control systems; Digital signal (RS485 / I²C interface, such as the 40-bit pulse of DHT11) Temperature and humidity probes are existing technology, so they will not be described in detail in this solution. When the humidity at the temperature probe 63 is too high, the temperature is also high. At this time, the electrical signal detected by the temperature probe 63 controls the air intake bladder 93 at the longitudinal partition 3, so that the electromagnetic micro pump 94 forms a negative pressure at the air intake bladder 93, absorbing the excess moisture in the seedling single chamber 4, and at the same time... By opening the telescopic air baffle 43 at the transverse partition 2 (the telescopic air baffle 43 is an electrically operated telescopic rod), the ventilation channel 8 at the transverse partition 2 is closed. Similarly, when the humidity and temperature are low and air needs to be introduced, the electromagnetic micro-pump 94 on the air inlet bladder 92 at the transverse partition 2 causes the air inlet bladder 92 to discharge air into the seedling single-chamber chamber 4. The electromagnetic micro-pump 94 absorbs outside air and discharges it into the seedling single-chamber chamber 4 from the air inlet bladder 92. The air intake or intake process in the seedling single-chamber chamber 4 is shown in the attached figure. Figure 9 As shown, air is introduced horizontally from the bottom and drawn vertically from the top, then introduced horizontally from the top and drawn vertically from the bottom. This keeps the gas in the seedling single chamber 4 in a flowing state. At the same time, because there is an inclined downward air inlet 54 at the top of the seedling cylinder 5 and an inclined upward air outlet 55 at the bottom of the seedling cylinder 5, the diameter of the air inlet 54 is larger than the diameter of the air outlet 55. This maintains the air flow in the seedling cylinder 5, which facilitates the sprouting of potato seed pieces in the seedling cylinder 5. After the potato seed pieces take root at the bottom, the potato seed roots grow along the conical seedling cylinder 5 until they absorb the nutrient solution through the permeable membrane 53. This helps maintain the development of the potato seed roots and avoids slow growth of the potato seed roots.
