Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of flower cultivation, and specifically relates to a constant-temperature culture device for Lycoris radiata and a culture method thereof. BACKGROUND

[0002] Lycoris radiata, also known as Lycoris radiata, is a perennial herbaceous flower of the Amaryllidaceae family. The bulb is similar to an onion, the flowers are large and beautiful, the flowering period is long, and it is a common ornamental plant. It is suitable for potting, courtyard planting or use as a cut flower. Lycoris radiata enters dormancy at low winter temperatures, stops nutrient growth, and accumulates nutrients for flower bud differentiation. Therefore, constant temperature treatment is required to simulate natural low temperature to activate endogenous hormones such as gibberellin in the bulb and induce flower bud formation. Through constant temperature treatment, the flowering period can be precisely controlled, and the quality and quantity of flowering can be improved.

[0003] The prior art document with application number CN120380951A discloses an efficient Lycoris radiata seedling cultivation device and an optimized cultivation method. The device includes a box, an electric motor is arranged on the inner wall of the box, a chain wheel one is fixedly arranged on the output end of the electric motor, a fixed plate is fixedly arranged at the bottom end of the chain wheel one, a chain is connected to the tooth end of the chain wheel one, a chain wheel two is connected to one end of the chain, a rotating shaft is fixedly arranged in the middle of the chain wheel two, one end of the rotating shaft is rotatably connected to one side of the fixed plate, a guide rail is arranged on the side wall of the fixed plate, and a plurality of fixed rods two are arranged on one side of the chain to form a cultivation box. Through the cooperative operation of the electric motor, the chain wheel, the chain, the cultivation box and the guide stabilizing structure, the Lycoris radiata seedlings are dynamically and stably cultivated in the box. The cultivation box always maintains an open and leaky hole upward stable state, which is beneficial to the healthy growth of the seedlings and solves the problem of unstable cultivation container in traditional dynamic cultivation.

[0004] Although the above-mentioned device improves the light, ventilation and water management of the germinated Lycoris radiata seedlings, it does not optimize and improve the process of flower bud differentiation. The bulb needs to be treated with constant temperature and dormancy before Lycoris radiata flower bud differentiation. The temperature control in the box needs to be precise and fast in response. In order to simulate the natural environment, hot air or cold air blowing method is usually used for temperature control. However, the seal of the cultivation box is usually installed on the side wall, which causes the bulbs close to the air outlet to be directly blown by the wind, resulting in rapid temperature rise or loss of water. On the contrary, the temperature regulation speed of the bulbs far from the seal is slow, resulting in uneven temperature in the box, which makes it difficult to effectively activate the endogenous hormones in the bulbs and reduces the success rate of cultivation.

[0050] As Figures 10 to 13 shown, a plurality of outer wind scooping plates 504 are fixedly connected to the air diffuser plate 501, and the number of the outer wind scooping plates 504 is the same as that of the air inlet connector 502, the inner surfaces of the outer wind scooping plates 504 are rotatably connected with inner wind scooping plates 507, and the surfaces of the outer wind scooping plates 504 and the inner wind scooping plates 507 are uniformly provided with a plurality of mutually matching air leakage holes; a pair of arc-shaped plates 508 are fixedly connected to the two sides of the inner wind scooping plate 507, and the arc-shaped plates 508 are both provided with inclined sliding grooves 5011; the arc-shaped plates 508 are both slidably connected with sliding blocks 509 through the inclined sliding grooves 5011, and the sliding blocks 509 are both fixedly connected with the cover 506.

[0051] Adopt the above scheme: because the four sides of the air diffuser plate 501 and the box body 1 are provided with air diffusing gaps, the air blown out of the box body 1 is first blocked by the air diffuser plate 501, and then is blown out along the gaps between the air diffuser plate 501 and the box body 1, so that the air is simultaneously blown out around the inner cavity of the box body 1, avoiding that the air is directly blown to the bulbs on one side. At this time, the ventilation pipe 505 extrudes the air inlet connector 502, pushes the cover 506 outward, exposes the air inlet hole grooves on the air inlet connector 502, and passes the air into the ventilation pipe 505, and uniformly blows out the air through the air outlets on the ventilation pipe 505, so that a plurality of equidistant air outlet points are arranged at the bottom of each layer of bulbs, effectively improving the air outlet uniformity and stability.

[0052] As Figures 2 to 5 shown, the positioning and anti-falling mechanism 6 includes a pair of U-shaped clamping plates 601 fixedly connected to the two ends of the support rod 3, the outer walls of the U-shaped clamping plates 601 are movably connected with L-shaped clamping plates 602, the side walls of the L-shaped clamping plates 602 are fixedly connected to the box body 1; a pair of limiting rods 603 are rotatably connected to the edges of the L-shaped clamping plates 602, and each pair of limiting rods 603 are elastically connected with each other, and the outer walls of the limiting rods 603 abut the U-shaped clamping plates 601.

[0053] As Figure 4As shown, the inner cavity of each L-shaped clamping plate 602 is provided with a pair of arc grooves 604, and the lower end of the limiting rod 603 is fixedly connected with a sliding column 605 which is slidingly connected in the arc groove 604.

[0054] By the above scheme, when the grid plate 4 needs to be disassembled and the layer spacing is changed, the staff can pinch the limiting rod 603 to retract into the inner cavity of the L-shaped clamping plate 602, so that the U-shaped clamping plate 601 is slidably moved out of the L-shaped clamping plate 602, and the limiting is released, which is simple and convenient to operate.

[0055] The application also provides a crocus sativus constant-temperature culture method, and the culture method is as follows:

[0056] S1, the bulb of crocus sativus is pretreated and constant-temperature dormant, first, healthy bulbs are selected, the outer layer of dry skin is peeled off, soaked in alcohol for one minute, then disinfected with mercuric chloride solution for ten minutes, then washed with sterile water for five times, then the bulbs are clamped into the placing plate, the spacing is selected, the supporting rod 3 and the grid plate 4 are clamped and locked by the positioning anti-falling mechanism 6, the placing plate containing the bulbs is placed on the grid plate 4, the double-layer box door 2 is closed, the temperature control module is started, the temperature of the relative low temperature is set, then the hot air and the cold air blown in the box body 1 are uniformly dispersed through the uniform temperature distribution mechanism 5, the constant-temperature mode is maintained for thirty to forty days, the endogenous hormone accumulation in the bulb is induced by low temperature, and the flower bud differentiation is completed.

[0057] S2, after the low temperature ends, the double-layer box door 2 is opened, a cutting knife is used, the cutting head is longitudinally incised three to four shallow marks along the surface of the bulb, and then the cut mark is sprayed with gibberellin solution to promote the dormancy removal.

[0058] S3, after the dormancy removal, the bulbs are transplanted in the culture medium, the medium is mixed with rotten leaf soil, perlite and vermiculite and adds rotten sheep manure, the pH value is adjusted, the bulbs are placed in the culture medium with a buried depth of two-thirds of the height of the bulbs, the bulbs and the culture medium are placed in the box body 1 for culture again, the spacing of each layer needs to be adjusted and locked through the positioning anti-falling mechanism 6, then the temperature control module is started, the temperature is raised through the uniform temperature distribution mechanism 5, the temperature is raised from five degrees to fifteen degrees within three days, then the temperature is kept stable at twenty degrees, the humidity is maintained in the range of seventy to eighty-five, the environment is transitioned, and the flower bud is transplanted after growing to a certain height.

[0059] S4, shading is performed in the early stage of transplantation, natural scattered light is simulated after seven days, nutrient solution is sprayed three days after planting, potassium fertilizer is additionally added from the seventh day, once a week, the flower sword is pulled out twenty to twenty-five days after transplantation, the flowering period is maintained for fifteen to twenty days, the flower stem is cut off after the flowers wither, and balanced fertilizer of nitrogen, phosphorus and potassium is supplemented to rejuvenate the bulbs.

[0060] The working principle and use process of the application are as follows:

[0061] First, the disinfection treatment after the bulb card into the placement tray, choose two L-shaped card plate 602 between the distance, usually can interval a little smaller, then the grid plate 4 is put into the box 1, the grid plate 4 bottom ventilation pipe 505 abuts into the air inlet joint 502 forward push, the U-shaped card plate 601 on both sides of the support rod 3 is clamped into the L-shaped card plate 602, and the staff can hand pinch limiting rod 603 into the inner cavity of L-shaped card plate 602, not hinder the U-shaped card plate 601 on the L-shaped card plate 602 sliding push, until the grid plate 4 abuts against the air diffuser plate 501, at this time the U-shaped card plate 601 completely through the limiting rod 603, limiting rod 603 under the action of spring force rotates to both sides, automatically lock the current position of U-shaped card plate 601, avoid its back, and limiting rod 603 in the rotating process through the slide column 605 in the arc groove 604 sliding, limit the rotation range. The placement tray containing bulb is placed on the grid plate 4, the double-layer box door 2 is closed, the temperature control module of the box 1 is started, the relative low temperature is set, the air outlet in the box 1 blows hot air or cold air, the environment in the box is kept at the set temperature;

[0062] Under the shielding effect of the air diffuser plate 501, the blown wind blows along the gap between the air diffuser plate 501 and the box 1, so that the air is blown out around the inner cavity of the box 1, avoiding the straight blowing of the wind to the bulb. And at this time, the ventilation pipe 505 extrudes the air inlet joint 502, pushes the cover 506 outward, exposes the air inlet hole slot on the air inlet joint 502, and passes the wind into the ventilation pipe 505, and adopts the air outlet on the ventilation pipe 505 to blow out evenly, so that there are several equidistant air outlet points at the bottom of each layer of bulb, effectively improving the air exhaust uniformity and stability. And when the temperature needs to be changed, the several air outlets in the box 1 can blow out hot air or cold air synchronously, greatly improving the response rate, and then improving the flower bud differentiation rate;

[0063] And, when the ventilation pipe 505 extrudes the air inlet joint 502 to move outward, the slider 509 on both sides of the cover 506 can be synchronously axially displaced, and the extrusion of the slider 509 in the inclined sliding groove 5011 can make the arc-shaped plate 508 drive the inner baffle 507 to rotate, so that the complete part of the inner baffle 507 coincides with the air leakage hole part of the outer baffle 504, and the outer baffle 504 and the inner baffle 507 form an air-tight air funnel, thereby improving the air inlet effect. Similarly, when the interval of the grille plate 4 needs to be changed, the ventilation pipe 505 is pulled out, the air inlet joint 502 is reset under the elastic force, the cover 506 is retracted, and the sealing and shielding are completed by being clamped on the check ring 5010, at the same time, the slider 509 moves reversely, extrudes the inclined sliding groove 5011, and makes the arc-shaped plate 508 rotate the inner baffle 507, at this time, the air leakage hole part of the inner baffle 507 and the outer baffle 504 coincide, and when blowing, the two cannot converge air, and do not affect the air flow to diffuse around along the air diffuser plate 501. Moreover, the greater the wind speed, the more tightly the cover 506 is blown and clamped with the check ring 5010, so that the part of the air diffuser plate 501 not connected by the ventilation pipe 505 will not be air permeable.
