Description

Technical Field

[0001] The invention relates to the technical field of agricultural breeding, in particular to a potato seedling raising device. Background Art

[0002] As a main food product, potatoes are widely planted due to their nutritional value, ease of planting and high yield. However, due to their uniqueness, potatoes are self-pollinating crops, and most varieties have low flowering rates or difficulty in setting seeds, making it extremely difficult to obtain seeds. Therefore, they need to be processed for seedling cultivation.

[0003] When raising potato seedlings, virus-free seed potatoes are first selected. The virus-free seed potatoes have high yield and good quality. They are cut into pieces and planted after they germinate. The bottom buds of potato seed potatoes are connected to the rhizomes and are prone to contain more plant pathogens, so the yield is low. The waist buds and the top buds have better germination quality. Therefore, when the potato seed potatoes are cut into pieces for germination, the waist buds and the top buds are cut into multiple small pieces along the buds so that the seed potato pieces can send out more sprouts. When ordinary farmers plant, they usually plant potato seed potatoes after cutting them into pieces when they germinate. However, for large agricultural product growers, they usually need to grow potato seedlings into seedlings before planting. Some use greenhouses for germination, and some use seedling beds for germination. Greenhouse planting requires a greenhouse, and seedling beds for germination are convenient to operate. At the same time, because there are multiple potato seed potato pieces stacked on the seedling bed, when one of the potato seed potato pieces rots, they will be infected and affected by each other, causing the soil of the entire seedling bed to be polluted. Therefore, we propose a potato seed potato seedling raising device. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please refer to the attached Figure 1 - Attachment Figure 11 The present invention provides a technical solution: a potato seed seedling raising device, including a seedling bed 1, the seedling bed 1 is a rectangular frame structure, and its specific size is customized according to the cultivation needs. In order to increase the stability of the seedling bed 1, four support columns are fixedly installed at the four corners of the bottom of the seedling bed 1. At the same time, in order to facilitate the adjustment of the height position of the seedling bed 1, the support columns are in a telescopic form, so that the height of the seedling bed 1 can be adjusted according to the needs. The seedling bed 1 is distributed with a plurality of transverse partitions 2 and longitudinal partitions 3. The distribution of the transverse partitions 2 and longitudinal partitions 3 is shown in the attached figure. Figure 3 and attached Figure 8 As shown in the figure, the transverse partitions 2 and the longitudinal partitions 3 form a plurality of single seedling chambers 4, and the transverse partitions 2 and the longitudinal partitions 3 are fixed to each other by plates, which are fixed by gluing or other means. The assembled transverse partitions 2 and longitudinal partitions 3 are assembled in the space of the seedling bed 1 manually or with lifting equipment.

[0021] The bottom of the single seedling chamber 4 is provided with a slot 41 for storing nutrient solution. The nutrient solution is for root absorption after the potato seed potatoes take root. The nutrient solution uses a special growth enhancer for underground rhizomes (core ingredients: 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, calcium (4%) and boron (0.5%) to prevent fruit cracking and enhance stress resistance).

[0022] A seedling cylinder 5 is placed on the top of the plug-in slot 41, and three layers of media with different densities are distributed inside the seedling cylinder 5. The medium layers inside the seedling cylinder 5 are a grass particle layer 57, a fine sand layer 58 and a coarse sand layer 59 from top to bottom, wherein the fine sand layer 58 is mixed with oil microbial agents, and the cut potato seed potatoes are buried in the fine sand layer 58, and the grass particle layer 57 distributed above it is made by cutting straw into granules and spreading it on the upper part of the fine sand layer 58. On the one hand, it is convenient for the potato seed potatoes to breathe after germination, and on the other hand, the grass particle layer 57 can absorb the humid air in the seedling single chamber 4, avoiding the environment at the seedling cylinder 5 from being too humid, thereby avoiding the potato seed potatoes from rotting after germination.

[0023] In order to ensure the temperature inside the seedling bed 1, which is conducive to the germination of potato seed potatoes, a skeleton layer 6 is installed on the seedling bed 1. The skeleton layer 6 is composed of horizontal and vertical skeleton bars 61. A fixing plate 62 is installed at the intersection of each horizontal and vertical skeleton bar 61, and a temperature probe 63 is installed at the bottom of the fixing plate 62. An adjustment seat 11 is installed on the seedling bed 1, and the skeleton bar 61 is inserted into the adjustment seat 11. During installation, the two ends of the horizontal and vertical frame bars 61 are inserted into the adjustment seat 11, and the horizontal and vertical frame bars 61 are inserted into the adjustment seat 11 to a corresponding depth according to the height of the frame layer 6. Then, the horizontal and vertical frame bars 61 are fixed to the position of the adjustment 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 on the seedling bed 1 by plates, stones and other objects. The four corners of the film 7 can also be tied to the seedling bed 1. At the same time, the film 7 is made of a transparent plastic film. The transparent plastic film is conducive to light or sunlight transmission, which is conducive to promoting the germination of potato seed potatoes. A ventilation channel 8 is provided on the transverse partition 2 and the longitudinal partition 3 , a ventilation component 9 is provided on the outer side of the seedling bed 1 , and the ventilation component 9 is communicated with the ventilation channel 8 .

[0024] Two ventilation channels 8 are provided on both the transverse partitions 2 and the longitudinal partitions 3, and an air port 42 communicating with the ventilation channel 8 is provided on the side wall of each single seedling raising chamber 4, and the air port 42 faces the seedling raising cylinder 5. The air ports 42 on the side wall of each single seedling raising chamber 4 are arranged from low to high. Each single seedling raising chamber 4 has four panels, and the air inlet sac 92 is distributed on the transverse partition 2. The air enters from the ventilation channel 8 at the bottom of one of the transverse partitions 2 and the ventilation channel 8 at the top of the opposite transverse partition 2. In this way, each single seedling raising chamber 4 can be ventilated at both the bottom and the top, effectively improving the air flow effect on the germination area of ​​the seed potatoes.

[0025] The seedling cylinder 5 is a cone structure, the top of the seedling cylinder 5 is a stabilizing ring 51, and the bottom of the seedling cylinder 5 is a cover 52 that cooperates with the plug-in groove 41. A water-permeable membrane 53 is provided at the place where the cover 52 communicates with the inside of the seedling cylinder 5. An air inlet slant 54 inclined downward is provided at the upper part of the seedling cylinder 5, and an air outlet slant 55 inclined upward is provided at the lower part of the seedling cylinder 5. The diameter of the air inlet slant 54 is larger than the diameter of the air outlet slant 55.

[0026] An isolation ring 56 is provided inside the seedling raising cylinder 5 .

[0027] The ventilation component 9 includes two pairs of ventilation groups, which are two ventilation bags 91 symmetrically installed on the outer wall of the seedling bed 1. The ventilation bags 91 are distributed with two upper and lower ventilation tubes 96, and the ventilation tubes 96 are connected to the ventilation channel 8. The ventilation bag 91 connected to the ventilation channel 8 on the transverse partition 2 is the air intake bag 92, and the ventilation bag 91 connected to the ventilation channel 8 on the longitudinal partition 3 is the air suction bag 93. The air intake bag 92 and the air suction bag 93 are both installed with electromagnetic micro pumps 94 on the outside, and the temperature sensor 63 monitors the temperature signal and transmits it to the controller of the electromagnetic micro pump 94. A telescopic air barrier rod 43 is installed at each seedling single chamber 4. A fixing frame 95 is installed on the outside of the ventilation bag 91, and the fixing frame 95 is connected to the seedling bed 1.

[0028] When in use, first bury the coarse sand layer 59 in the bottom layer of the seedling cylinder 5, then bury the cut potato seed potato pieces in the middle layer of the seedling cylinder 5, clamp the potato seed potato pieces through the isolation ring 56, so that the cut surface of the potato seed potato pieces faces down and the position with the bud eyes faces up, then fill the middle layer of the seedling cylinder 5 with a fine sand layer 58, and finally lay a layer of grass grain layer 57 on the top of the fine sand layer 58, install the cover body 52 at the bottom of the seedling cylinder 5 in the plug-in groove 41 filled with nutrient solution, and after the multiple seedling cylinders 5 in the seedling bed 1 are all stacked, the horizontal and vertical skeleton strips 6 are laid as needed. 1, according to the height of the skeleton layer 6, the horizontal and vertical skeleton bars 61 are inserted into the corresponding depth along the adjustment seat 11, and then the horizontal and vertical skeleton bars 61 are fixed to the position of the adjustment seat 11 by fixing nuts or cable ties. At the same time, the outside of the skeleton layer 6 is covered with a film 7. Under the support of the skeleton layer 6, the film 7 forms a corresponding space. The four sides of the film 7 are pressed on the seedling bed 1 by plates, stones and other objects. The four corners of the film 7 can also be tied to the seedling bed 1. At the same time, the film 7 is made of transparent plastic film, which is conducive to light or sunlight transmission, thereby promoting the germination of potato seed potatoes.

[0029] Because a fixing plate 62 is installed at the intersection of each horizontal and vertical skeleton bar 61, and a temperature sensor 63 is installed at the bottom of the fixing plate 62, the temperature sensor 63 is a temperature and humidity sensor. (Humidity sensing mechanism, Capacitive sensing: The dielectric constant of polymer materials changes with humidity, and the capacitance value increases with increasing humidity (formula: C=C0+k⋅RHC=C0+k⋅RH) 5. Resistive sensing: The resistance value of humidity-sensitive materials (such as lithium oxide) decreases with increasing humidity, and the conductivity increases by 5. Synchronous temperature correction is required because humidity is a function of temperature to avoid measurement deviation 5. Temperature sensing mechanism, Heat Resistive type: The resistance value of platinum metal is linearly related to temperature (RT=R0(1+αT)RT=R0(1+αT))5. Thermocouple type: Based on the Seebeck effect, the temperature difference generates thermoelectromotive force (E=S⋅ΔTE=S⋅ΔT)5. Thermistor: There are positive and negative temperature coefficient types, and the calibration curve must be matched to the nonlinear change5. Signal processing process: The original electrical signal is filtered to reduce noise, amplified and enhanced, and then converted and output5. Output forms include: analog signal (4–20mA current / 0–10V voltage) adapted to industrial control systems; digital signal (RS485 / I 2 C interface) such as the 40-bit pulse of DHT11) temperature and humidity probe is the existing technology, so it will not be introduced in detail in this scheme. When the humidity at the monitoring point of the temperature sensor 63 is too high, the temperature is high. At this time, the electrical signal monitored by the temperature sensor 63 controls the air suction bag 93 at the longitudinal partition 3, so that the electromagnetic micro pump body 94 forms a negative pressure at the air suction bag 93 to absorb excess moisture in the seedling single chamber 4. At the same time, by opening the telescopic air barrier rod 43 at the transverse partition block 2, the telescopic air barrier rod 43 is an electric telescopic rod, thereby closing the ventilation channel 8 at the transverse partition 2. Similarly, when the humidity is low and the temperature is low and air needs to be discharged, the electromagnetic micro pump body 94 on the bag 92 is made through the transverse partition 2, so that the air intake bag 92 discharges air to the seedling single chamber 4, and the electromagnetic micro pump body 94 absorbs external air and discharges it from the air intake bag 92 into the seedling single chamber 4. The air intake or air intake process in the seedling single chamber 4 is as shown in the attached figure. Figure 9 As shown in the figure, air is introduced horizontally from the bottom and inhaled longitudinally from the top, then air is introduced horizontally along the top and inhaled longitudinally along the bottom, so that the gas in the single seedling chamber 4 is in a flow state. At the same time, because an air inlet slant 54 inclined downward is provided at the upper part of the seedling cylinder 5, and an air outlet slant 55 inclined upward is provided at the lower part of the seedling cylinder 5, the diameter of the air inlet slant 54 is larger than the diameter of the air outlet slant 55, so the flow of air in the seedling cylinder 5 is maintained, and the germination of the potato seed potato pieces in the seedling cylinder 5 is convenient. After the potato seed potato pieces take root at the bottom, the potato seed potato roots grow along the cone-shaped seedling cylinder 5 until they absorb the nutrient solution through the water-permeable membrane 53, which is beneficial to maintain the development of the potato seed potato root system and avoid slow growth of the potato seed potato root system.
