Description

Technical Field

[0001] The invention belongs to the technical field of promoting seedling growth, in particular to a device for promoting seedling growth and a method for promoting seedling growth. Background Art

[0002] Liaodong Oak is a typical oak species, named after its well-developed cork layer. It has a wide distribution range and is an excellent tree species for constructing protective forests such as windbreak and sand fixation forests and water conservation forests. The natural regeneration of Liaodong Oak is mostly based on germination, and the regeneration of seedlings propagated by seeds is difficult, which has become the key restricting the healthy and stable growth of Liaodong Oak forests.

[0003] Patent publication number CN106416905A discloses a spring net-covered semi-direct seeding afforestation technology for Quercus liaotungensis, which includes the following steps: 1. Seed collection; 2. Seed insecticide treatment, using a closed drug fumigation method to kill most weevils and their eggs that harm oak nuts; 3. Seedling cultivation (germination); 4. Afforestation site preparation; 5. Netting and transplanting. This scheme saves seeds, not only has a high germination rate, thereby indirectly improving the survival rate of seedlings, but also has a high cotyledon retention rate, eliminating the investment in seed storage, avoiding losses, and greatly saving afforestation costs.

[0004] In the above scheme, when the seeds are subjected to insecticide treatment, the selected seeds need to be placed in a drug pool and soaked for 1-2 hours. After soaking, the seeds need to be taken out of the soaking pool for drying. Since the seed soaking and drying are processed separately, the seeds need to be transferred between different devices during this process. Since a large amount of medicine remains on the seeds after soaking, in order to avoid the medicine from being scattered into the surrounding environment during transportation, causing the surrounding environment to be polluted by the medicine, the seeds need to be drained before being taken out of the drug pool. Draining will waste a lot of time, thereby reducing the efficiency of the entire seed insecticide treatment. For this reason, the present invention provides a device for promoting seedling growth and a method for promoting seedling growth. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a method for promoting seedling growth according to the present invention comprises the following steps:

[0008] Step 2: Seed treatment: remove the fruits with insect holes from seeds I and II, select large and plump seeds, and then put the selected seeds into a drug soaking device for insecticide and drying to obtain seeds for sowing;

[0009] Step 3: In late October of the first year, sow seeds in areas where there are insufficient saplings of Quercus liaotungensis (or in forest windows) in secondary or coniferous forests of Quercus liaotungensis, and then fill in the original soil.

[0010] Step 4: Improve the habitat before seedlings emerge. After sowing, in late April of the second year, remove the thicker dead leaves and dead shrubs and grasses within the sowing hole, and maintain an appropriate thickness of dead leaves cover;

[0011] Step 5: Improve the habitat after the seedlings emerge from the soil. In the second and third years after the seedlings emerge from the soil, weed and loosen the soil around the seedlings at regular intervals. During this period, screen multiple seedlings in one hole and select the seedlings with the best growth conditions. After the fourth year of seedling growth, light-transmitting cuts should be carried out around the seedlings in a timely manner to remove shrubs or trees that block the seedlings from receiving light.

[0013] As the chain keeps conveying, the soaked seeds will be continuously conveyed to the bottom of the drying hood. At the same time, the hot air sprayed from the air outlet will dry the moving seeds. The dried seeds will be automatically conveyed out of the soaking box, so that the seed conveying and drying are carried out simultaneously, which improves the seed drying efficiency.

[0014] Preferably, three sets of support wheels are fixedly mounted on the driven shaft and the driving shaft, and the outer rings of the support wheels fit the wire mesh;

[0015] The rotating support wheel not only supports the wire mesh, but also guides the turning of the wire mesh.

[0016] Preferably, the partition includes a fixed sleeve, the end of the fixed sleeve is fixedly connected to the chain, a movable plate movably plugged into the fixed sleeve, two groups of springs symmetrically arranged in the fixed sleeve, two groups of pins, and the two groups of pins are respectively installed on both sides of the movable plate, one end of the movable plate is symmetrically provided with two groups of limiting grooves for placing springs, one end of the spring is fixedly connected to the inner wall of the fixed sleeve, and the other end of the spring is fixed in the limiting groove, and guide surfaces for guiding the pins are provided on both sides of the soaking box, the guide surfaces are composed of a first arc surface, an oblique surface, a straight line surface, and a second arc surface, six groups of fixing strips are equidistantly installed at the lower end of the drying cover, and a number of groups of shifting rods for shifting seeds are provided on the fixing strips, and avoidance openings for avoiding the pins are provided at both ends of the fixed sleeve;

[0017] The upper end surface of the movable plate is flush with the surface of the wire mesh, and the pin will continue to slide along the straight surface toward the second curved surface. At the same time, the seeds to be dried move under the drying cover along with the wire mesh, and the moving seeds are moved by several groups of levers, so that the seeds are in an active state, which is conducive to the volatilization of moisture.

[0018] Preferably, a filtering mechanism is provided at the other end of the immersion tank, and the filtering mechanism includes a shell, which is fixedly mounted on the other end of the immersion tank, two sets of side panels fixedly mounted on both sides of the shell, a filter screen fixedly connected to one set of side panels, a water pump, the water pump fixedly mounted on the immersion tank, a first water pipe connected to the water inlet of the water pump, a second water pipe connected to the water outlet of the water pump, the first water pipe is fixedly connected to one set of side panels, one end of the second water pipe extends into the interior of the immersion tank, and a liquid outlet is opened at one end of the immersion tank, and the liquid outlet faces the interior of the shell;

[0019] As the medicine liquid continues to be discharged into the soaking box, the liquid level in the soaking box will rise, and the medicine liquid will overflow the liquid outlet, causing the medicine liquid to fall back into the shell. At the same time, the hollow seeds inside will move toward the liquid outlet with the flow of the medicine liquid, causing the hollow seeds inside to fall into the shell and be filtered on the filter net, thereby realizing automatic cleaning of the hollow seeds inside and ensuring the quality of the seeds after drying.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. As the chain keeps conveying, the soaked seeds will be continuously conveyed to the bottom of the drying hood. At the same time, the hot air sprayed from the air outlet will dry the moving seeds. The dried seeds will be automatically conveyed out of the soaking box, so that the seed conveying and drying are carried out simultaneously, which improves the drying efficiency of the seeds.

[0022] 2. When the seeds to be dried move toward the bottom of the drying cover, the pin on the partition will first contact the first curved surface, and the pin will slide along the first curved surface. Then, the pin will slide along the first curved surface to the oblique surface. The pin will be squeezed by the oblique surface, causing the pin to drive the movable plate to slide downward along the inner cavity of the fixed sleeve, and the movable plate compresses the spring until the pin slides to the intersection of the straight surface and the oblique surface. At this time, the upper end surface of the movable plate is flush with the surface of the wire mesh, and the pin will continue to slide along the straight surface toward the second curved surface. At the same time, the seeds to be dried move under the drying cover with the wire mesh, and the moving seeds are moved by several groups of levers, so that the seeds are in a movable state, which is conducive to moisture volatilization, until the pin is out of contact with the second curved surface. Under the action of the rebound force of the spring, the movable plate is re-extended from the fixed sleeve, and then the movable plate enters the fixed sleeve, so that the space between the two adjacent piles of seeds is released, so that the seed placement space becomes larger, otherwise the density of the seeds relative to the space is reduced, which is conducive to the seeds being dried quickly.

[0023] 3. During the seed soaking process, the water pump is started, and the water pump draws out the medicinal liquid stored in the shell in advance through the first water pipe. The liquid level of the medicinal liquid is lower than the filter net, and then the medicinal liquid is discharged into the soaking box through the second water pipe. As the medicinal liquid continues to be discharged into the soaking box, the liquid level in the soaking box will rise, and the medicinal liquid will overflow the liquid outlet, causing the medicinal liquid to fall back into the shell. At the same time, the hollow seeds inside will move toward the liquid outlet with the flow of the medicinal liquid, causing the hollow seeds inside to fall into the shell and be filtered on the filter net, thereby realizing automatic cleaning of the hollow seeds inside and ensuring the quality of the seeds after drying.

[0034] 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.

[0035] Example 1

[0036] A method for promoting seedling growth according to an embodiment of the present invention comprises the following steps:

[0037] Step 1: Seed collection: From mid-September to early October of the first year, select well-growing seedling trees and directly pick the brown seeds from the trees to obtain seeds I, or pick up fallen Quercus liaotungensis fruits to obtain seeds II;

[0038] Step 2: Seed treatment: remove the fruits with insect holes from seeds I and II, select large and plump seeds, and then put the selected seeds into a drug soaking device for insecticide treatment and drying to obtain seeds for sowing;

[0039] Step 3: In late October of the first year, sow seeds in areas where there are insufficient saplings of Quercus liaotungensis (or in forest windows) in secondary or coniferous forests of Quercus liaotungensis, and then fill in the original soil.

[0040] Step 4: Improve the habitat before seedlings emerge. After sowing, in late April of the second year, remove the thicker dead leaves and dead shrubs and grasses within the sowing hole, and maintain an appropriate thickness of dead leaves cover;

[0041] Step 5: Improve the habitat after the seedlings emerge from the soil. In the second and third years after the seedlings emerge from the soil, weed and loosen the soil around the seedlings at regular intervals. During this period, screen multiple seedlings in one hole and select the seedlings with the best growth conditions. After the fourth year of seedling growth, light-transmitting cuts should be carried out around the seedlings in a timely manner to remove shrubs or trees that block the seedlings from receiving light.

[0042] Furthermore, in order to optimize the method for promoting seedling growth, the embodiment of the present invention improves the medicinal soaking device required to promote seedling growth. The medicinal soaking device integrates soaking and drying. After the seeds are soaked, they are transported and dried simultaneously, which saves the time for seed transportation and improves the drying efficiency of the seeds.

[0043] Example 1

[0044] like Figure 1 and Figure 2 As shown, a device for promoting seedling growth is suitable for the above-mentioned method for promoting seedling growth, comprising a soaking box 1, a conveying mechanism 2 is arranged in the soaking box 1, a drying cover 3 is arranged above the conveying mechanism 2, a plurality of air outlet holes 301 for blowing air are opened on the lower end surface of the drying cover 3, a hot air pipe 4 is connected to the upper end of the drying cover 3, a discharge plate 5 is fixedly installed at one end of the soaking box 1, the conveying mechanism 2 comprises two sets of chains 201, each set of chains 201 meshes with two sets of ratchets 202, and two sets of driving shafts 203, two sets of ratchets 202 are installed on the fixed sleeve 2061 of each driving shaft 203, and the driving shaft 203 is rotatably installed in the immersion box 1, a guide wheel 204 for guiding the chain 201, a driven shaft 205, the guide wheel 204 fixed sleeve 2061 is installed on the driven shaft 205, the driven shaft 205 is rotatably installed in the immersion box 1, several sets of partitions 206 are fixedly installed between the two sets of chains 201, and several sets of wire meshes 207 are fixedly installed between the partitions 206.

[0045] Specifically, attached Figure 2The direction indicated by the middle arrow is the transmission direction of the chain 201, one end of the hot air pipe 4 is connected to the heating equipment, the wire mesh 207 has good elasticity, and the immersion box 1 contains a liquid medicine for killing insects, and the liquid level of the liquid medicine is lower than the upper end of the discharge plate 5. When the seeds need to be killed, the seeds to be killed are poured into the immersion box 1, and the seeds are soaked in the liquid medicine, and the pests on the seeds are killed by the liquid medicine. After the seeds are soaked for 1-2 hours, a group of driving shafts 203 are driven to rotate by a group of motors, and a group of driving shafts 203 drives two groups of ratchets 202 to rotate. As the ratchet 202 rotates, the chain 201 and several groups of partitions 206 and several groups of wire meshes 207 make circular motions around the ratchet 202 and the guide wheel 204. As the partitions 206 and the wire mesh 207 make circular motions, the cooperation between the partitions 206 and the wire mesh 207 causes the seeds on the wire mesh 207 to slowly The seeds are automatically separated from the immersion box 1 as the chain 201 is continuously conveyed, and the soaked seeds are continuously conveyed to the bottom of the drying hood 3. At the same time, the hot air sprayed from the air outlet 301 dries the moving seeds. The dried seeds are automatically conveyed out of the immersion box 1, so that the seed conveying and drying are carried out simultaneously, thereby improving the seed drying efficiency.

[0046] like Figure 3 As shown, three sets of support wheels 35 are installed on the fixed sleeves 2061 on the driven shaft 205 and the driving shaft 203, and the outer rings of the support wheels 35 are in contact with the wire mesh 207.

[0047] Specifically, when the partition 206 and the wire mesh 207 make circular motion, the partition 206 and the wire mesh 207 will drive the support wheel 35 to rotate. The rotating support wheel 35 not only supports the wire mesh 207, but also guides the turning of the wire mesh 207.

[0048] like Figures 4 to 6As shown, the partition 206 includes a fixed sleeve 2061, the end of the fixed sleeve 2061 is fixedly connected to the chain 201, a movable plate 2062 movably inserted in the fixed sleeve 2061, two groups of springs 2063 symmetrically arranged in the fixed sleeve 2061, two groups of pins 2064, and the two groups of pins 2064 are respectively installed on both sides of the movable plate 2062. Two groups of limiting grooves 621 for placing the springs 2063 are symmetrically opened at one end of the movable plate 2062. One end of the spring 2063 is fixedly connected to the fixed sleeve 2061. The inner wall of the drying hood 3 is provided with six groups of fixing bars 302 at equal distances, and the fixing bars 302 are provided with several groups of shifting rods 303 for shifting seeds. Both ends of the fixing sleeve 2061 are provided with avoidance openings 611 for avoiding the pin shaft 2064.

[0049] Specifically, when the seeds are conveyed to the bottom of the drying cover 3, the seeds to be dried are located on the wire mesh 207 and are limited between the two groups of partitions 206, causing the seeds to be dried to pile up together. The piled-up seeds are not conducive to water volatilization and affect the seed drying efficiency. Therefore, when the seeds to be dried move toward the bottom of the drying cover 3, the pin 2064 on the partition 206 will first contact the first curved surface 11, and the pin 2064 slides along the first curved surface 11, and then the pin 2064 slides along the first curved surface 11 to the inclined surface 12, and the pin 2064 will be squeezed by the inclined surface 12, so that the pin 2064 drives the movable plate 2062 to slide downward along the inner cavity of the fixed sleeve 2061, and the movable plate 2062 compresses the spring 2063 until the pin 2064 slides to the straight line At the intersection of surface 13 and oblique surface 12, the upper end surface of movable plate 2062 is flush with the surface of wire mesh 207, and pin shaft 2064 will continue to slide along straight surface 13 toward the second curved surface 14. At the same time, the seeds to be dried move under the drying cover 3 along with the wire mesh 207, and the moving seeds are moved by several groups of shifting rods 303, so that the seeds are in an active state, which is conducive to the volatilization of water, until the pin shaft 2064 is out of contact with the second curved surface 14, and under the action of the rebound force of spring 2063, the movable plate 2062 is extended from the fixed sleeve 2061 again, and then the movable plate 2062 enters the fixed sleeve 2061, so that the space between the two adjacent piles of seeds is released, so that the seed placement space becomes larger, and vice versa, the density of the seeds relative to the space is reduced, which is conducive to the seeds being dried quickly.

[0050] like Figure 1 、 Figure 7 、 Figure 8As shown, a filtering mechanism 6 is provided at the other end of the soaking tank 1, and the filtering mechanism 6 includes a shell 601, which is fixedly mounted on the other end of the soaking tank 1, two groups of side panels 602 fixedly mounted on both sides of the shell 601, a filter screen 603 fixedly connected to one group of side panels 602, a water pump 605, the water pump 605 is fixedly mounted on the soaking tank 1, a first water pipe 604 connected to the water inlet of the water pump 605, a second water pipe 606 connected to the water outlet of the water pump 605, the first water pipe 604 is fixedly connected to one group of side panels 602, and one end of the second water pipe 606 extends into the interior of the soaking tank 1, and a liquid outlet 102 is provided at one end of the soaking tank 1, and the liquid outlet 102 is directly facing the interior of the shell 601.

[0051] Specifically, the liquid level in the soaking box 1 is flush with the liquid outlet 102. When the seeds are put into the soaking box 1 for soaking, a small number of seeds are eaten by pests, making the seeds hollow inside. The hollow seeds inside will float freely on the liquid surface. However, if the hollow seeds inside are not cleaned up, when the seeds are conveyed to the bottom of the drying cover 3 for drying, the hollow seeds inside will be conveyed away together, resulting in the drying seeds being mixed with bad seeds, affecting the seed quality. Therefore, during the seed soaking process, the water pump 605 is started, and the water pump 605 uses the first water pipe 604 to pump the water stored in the shell 60 in advance. 1 is extracted, and the liquid level of the liquid is lower than the filter 603, and then the liquid is discharged into the soaking box 1 through the second water pipe 606. As the liquid continues to be discharged into the soaking box 1, the liquid level in the soaking box 1 will rise, and the liquid will overflow the liquid outlet 102, causing the liquid to fall back into the shell 601. At the same time, the hollow seeds inside will move toward the liquid outlet 102 with the flow of the liquid, causing the hollow seeds inside to fall into the shell 601 and be filtered on the filter 603, thereby realizing automatic cleaning of the hollow seeds inside and ensuring the quality of the seeds after drying.

[0052] Working principle: Pour the seeds to be killed into the soaking box 1, soak the seeds in the liquid medicine, and kill the pests on the seeds through the liquid medicine. After the seeds are soaked for 1-2 hours, a group of motors drives a group of active shafts 203 to rotate, and a group of active shafts 203 drives two groups of ratchets 202 to rotate. As the ratchet 202 rotates, the chain 201 and several groups of partitions 206 and several groups of wire mesh 207 make circular motions around the ratchet 202 and the guide wheel 204. As the partitions 206 and the wire mesh 207 make circular motions, the cooperation of the partitions 206 and the wire mesh 207 makes the The seeds on the wire mesh 207 slowly move toward the bottom of the drying cover 3, and at the same time, the seeds are automatically separated from the liquid medicine, and under the action of gravity, most of the excess liquid medicine on the seeds will automatically fall back into the soaking box 1. At this time, the heating device is started, and the heating device introduces hot air into the drying cover 3 through the hot air pipe 4. The hot air is sprayed downward through the air outlet 301 on the drying cover 3. The hot air is blown directly onto the seeds below, so that the excess liquid medicine on the seeds is dried. The dried seeds will be conveyed to the discharge plate 5, and the seeds will directly fall onto the discharge plate 5, so that the seeds are separated from the soaking box 1;

[0053] When the seeds to be dried move toward the bottom of the drying cover 3, the pin 2064 on the partition 206 will first contact the first curved surface 11, and the pin 2064 will slide along the first curved surface 11, and then the pin 2064 will slide along the first curved surface 11 to the oblique surface 12, and the pin 2064 will be squeezed by the oblique surface 12, so that the pin 2064 drives the movable plate 2062 to slide downward along the inner cavity of the fixed sleeve 2061, and the movable plate 2062 compresses the spring 2063 until the pin 2064 slides to the intersection of the straight surface 13 and the oblique surface 1 2 intersection, at which time the upper end surface of the movable plate 2062 is flush with the surface of the wire mesh 207, and the pin 2064 will continue to slide along the straight surface 13 toward the second curved surface 14. At the same time, the seeds to be dried move under the drying cover 3 along with the wire mesh 207, and the moving seeds are moved by the groups of shifting rods 303, so that the seeds are in a movable state, which is conducive to the volatilization of moisture, until the pin 2064 is out of contact with the second curved surface 14, and under the action of the rebound force of the spring 2063, the movable plate 2062 is re-extended from the fixed sleeve 2061;

[0054] During the seed soaking process, the water pump 605 is started, and the water pump 605 extracts the medicinal liquid stored in the shell 601 in advance through the first water pipe 604. The liquid level of the medicinal liquid is lower than the filter 603, and then the medicinal liquid is discharged into the soaking box 1 through the second water pipe 606. As the medicinal liquid continues to be discharged into the soaking box 1, the liquid level of the medicinal liquid in the soaking box 1 will rise, and the medicinal liquid will overflow the liquid outlet 102, causing the medicinal liquid to fall back into the shell 601. At the same time, the hollow seeds inside will move toward the liquid outlet 102 with the flow of the medicinal liquid, causing the hollow seeds inside to fall into the shell 601 and be filtered on the filter 603.
