Description

Technical Field

[0001] The invention relates to the field of flower branch propagation, in particular to a cutting propagation method for Orchidaceae and a special cutting potted plant. Background Art

[0002] Li's orchid is a new species of orchid discovered by the Chinese Academy of Tropical Agricultural Sciences in Hainan. Li's orchid, a new species of orchid discovered in Hainan, has its information included in the International Plant Name Index.

[0003] The invention with the existing application number 201610475648.3 discloses a branching propagation method for orchids. By drying the branches after clearing the weeds, the root rot phenomenon after division can be reduced and the cutting process during division is convenient. The composition of the culture medium is organic and inorganic active fertilizer, Inoue Zheng microbial fertilizer and potassium humate organic fertilizer and the content can improve the quality of orchids and the nutrient accumulation of orchids, thereby improving their resistance. The fertilizer management is carried out at the same time as disease and pest management to reduce the impact of diseases and pests on orchids. Since the lateral buds of Li's orchid are not developed, usually only rhizomes but no lateral buds grow, so it is not suitable for this branching method. The present invention mainly uses hormones and EM composite probiotics to jointly promote the germination of stems and roots of Li's orchids to achieve a seedling propagation method. Summary of the Invention

[0004] In order to overcome the disadvantages that general orchid reproduction mainly relies on asexual reproduction or sterile sowing, but the lateral buds of Li's orchid are not developed and only rhizomes grow, which are not suitable for its division reproduction application, the present invention provides a Li's orchid cutting propagation method and a special cutting potted plant.

[0005] A cutting propagation method for Orchidaceae of the present invention comprises the following steps:

[0006] Step 1: Use rooting agent to promote the growth of the rhizomes of the Lishi orchid. Spray once every three days until the roots of the Lishi orchid grow out from the side.

[0007] Step 2: Use 6-BA to induce the growth of the middle bud point in the stem root, apply it to the horizontal stem root that has grown out of the Li Shilan orchid, and apply it once a week until the stem root grows a bud;

[0008] Step 3: Use EM compound probiotic planting solution, dilute it, and spray the Lishilan orchid weekly in combination with step 2;

[0009] Step 4: Rooting: When the newly emerged seed buds grow to 10 cm in height, apply NAA and rooting agent to the rhizome of the Lishilan orchid.

[0010] Step 5: Division. After the above four steps, the orchid becomes a complete plant. Cut off the part of the orchid that needs to be cut and disinfect it with 75% alcohol and carbendazim.

[0011] Step 6: Planting: After the freshly cut Lishilan orchid is disinfected and dried, it is planted in the cutting pot;

[0012] Step seven, water and light management. The wounds of the newly planted Li's orchid have not yet healed completely. Cover the cutting pot with a shade net with a shading rate of 70% for 7 days to create a weak light environment during the recovery period. Do not water during the recovery period. After 7 days, observe that the aquatic plants and bark are in a dry state, water them thoroughly again, and then water them every 3 days.

[0013] Preferably, the rooting agent is prepared at a concentration of 2 mg / L in step 1, and is sprayed once every three days for one month.

[0014] Preferably, in step 2, the concentration of 6-BA is 10 mg / L, and the application is performed once a week for 5 consecutive weeks.

[0015] Preferably, in step 4, the concentration of NAA is 0.5 mg / L, and the concentration of the rooting agent is 1 mg / L.

[0016] Preferably, in step six, the steps of planting the orchid in the cutting pot are as follows: spreading a layer of bark on the cutting pot, wrapping the rhizome of the orchid with a handful of water grass, placing it upright in the middle of the cutting pot, and then filling the surrounding rhizome with bark.

[0017] Preferably, in step seven, on the third day after the shade net covers the cutting potted plants, check whether white callus spots appear on the cut parts of the orchid. If white callus spots have been formed, replace the shade net with a shading rate of 70% with a shade net with a shading rate of 45%. If white callus spots are not formed, maintain the shade net with a shading rate of 70% and move it to an environment with better ventilation conditions to enhance ventilation.

[0018] Preferably, in step seven, on the fifth day after the shade net covers the cutting potted plants, the shade net is briefly removed and tested for 2 hours continuously. If the leaves of the orchid do not wilt, the shading time is gradually reduced. If the leaves of the orchid show curling, the shading is immediately restored.

[0019] The present invention provides a special cutting pot for propagation of Li's orchid by cuttings, comprising a flower pot, an insert tube, a height-adjusting screw rod, a motor, a lifting slider, a counterweight slider, a pull rope, a fixing frame, an inclined rail, a main shade net and an auxiliary shade net; the flower pot is inserted with the insert tube; the insert tube is rotatably connected with the height-adjusting screw rod; the insert tube is installed with a motor that drives the height-adjusting screw rod to rotate forward or reversely; the output shaft of the motor is fixedly connected to the height-adjusting screw rod; the insert tube is slidably connected with the lifting slider; the threaded structure of the height-adjusting screw rod is screwed to the lifting slider; a number of fixing frames are fixed on the insert tube; the fixing frame is connected with an inclined rail; the inclined rail is slidably connected with the counterweight slider; the pull rope is fixed to the counterweight slider; the pull rope is fixed to the lifting slider; the main shade net is fixed between two adjacent inclined rails; the auxiliary shade net is fixed between two adjacent pull ropes, the auxiliary shade net is located above the corresponding main shade net, and the mesh density of the main shade net is twice that of the mesh density of the auxiliary shade net.

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] A cutting propagation method for Orchidaceae of the present invention comprises the following steps:

[0033] Step 1: Use 2mg / L rooting agent to promote the growth of the rhizomes of the Lishi orchid. Spray once every three days for a month until the roots of the Lishi orchid grow out from the side.

[0034] Step 2: Use 10 mg / L 6-BA to induce the growth of the middle bud point in the stem root. Apply it to the horizontal stem root that has grown out of the Li Shilan orchid once a week for 5 consecutive weeks until the stem root grows a bud;

[0035] Step 3: Use EM compound probiotic planting solution, dilute it, and spray the Lishilan orchid weekly in combination with step 2;

[0036] Step 4: Rooting: When the newly emerged seed buds grow to 10 cm in height, apply 0.5 mg / L NAA and 1 mg / L rooting agent to the rhizome of the orchid.

[0037] Step 5: Division. After the above four steps, the orchid becomes a complete plant. Cut off the part of the orchid that needs to be cut and disinfect it with 75% alcohol and carbendazim.

[0038] Step 6: Planting. After the freshly cut Li's orchid is disinfected and dried, it is planted in the cutting pot. The specific planting steps are: spread a layer of bark on the cutting pot, wrap the rhizome of Li's orchid with a handful of water grass, place it upright in the middle of the cutting pot, and then fill the surrounding rhizome with bark.

[0039] Step seven, water and light management. The wounds of the newly planted Li's orchid have not yet healed completely. Cover the cutting pot with a shade net with a shading rate of 70% for 7 days to create a weak light environment during the recovery period. This can not only reduce water loss, but also avoid strong light causing stomatal closure, maintain basic photosynthesis, and prevent the incisions that have not adapted to the environment from forming necrotic spots under direct sunlight. Do not water during the recovery period. After 7 days, observe that the water plants and bark are in a dry state and water them thoroughly again. Then water them every 3 days.

[0040] A special cutting pot plant for propagation of Orchidaceae cuttings, such as Figures 1-6 As shown, it includes a flower pot 1, an insert tube 2, a height adjustment screw rod 21, a motor 22, a lifting slider 23, a counterweight slider 24, a pull rope 25, a fixing frame 31, an inclined rail 32, a main shade net 4 and an auxiliary shade net 5; the flower pot 1 is used as a cutting pot, and a plurality of partition plates 11 are inserted into the flower pot 1; the insert tube 2 is inserted into the flower pot 1; the insert tube 2 is rotatably connected with the height adjustment screw rod 21; the motor 22 is installed in the insert tube 2; the output shaft of the motor 22 is fixedly connected to the height adjustment screw rod 21; the insert tube 2 is slidably connected with the lifting slider 23; the threaded structure of the height adjustment screw rod 21 is screwed to the lifting slider 23; the insert tube 2 is fixed with There are fixing frames 31 with corresponding number and position of partition plates 11; each fixing frame 31 is connected to an inclined rail 32; each inclined rail 32 is slidably connected to a counterweight slider 24; each counterweight slider 24 is fixed with a pull rope 25; the upper ends of all pull ropes 25 are fixed to the lifting slider 23; a main shade net 4 is fixed between each two adjacent inclined rails 32; an auxiliary shade net 5 is fixed between each two adjacent pull ropes 25, and the auxiliary shade net 5 is located above the corresponding main shade net 4, and the mesh density of the main shade net 4 is twice the mesh density of the auxiliary shade net 5.

[0041] Before planting the orchid of Li's family in a special cutting pot for propagation of orchid of Li's family cuttings of the present invention, the staff will remove the cutting tube 2 and the fixed frame 31, the inclined rail 32, the main shade net 4 and the auxiliary shade net 5 connected thereto from the flower pot 1, and then the staff will pour the nutrient soil into the flower pot 1, and the nutrient soil in the flower pot 1 will be divided into several independent cutting areas by the partition plate 11. Then the staff will insert the cut orchids of Li's family into the independent cutting areas in the flower pot 1, and then the staff will reinsert the cutting tube 2 back into the flower pot 1. Figure 1As shown, at this time all the main shade nets 4 and all the auxiliary shade nets 5 are in the state of being opened and covering the top of the flower pot 1, and the shade net composed of all the main shade nets 4 and all the auxiliary shade nets 5 with a shading rate of 70% covers the cutting potted plants to create a weak light environment.

[0042] On the third day after the shade net covered the cutting potted plants, the staff removed the insert tube 2 and the fixed frame 31, inclined rail 32, main shade net 4 and auxiliary shade net 5 connected thereto from the flower pot 1, and observed the incision of the cut part of the orchid. When the staff observed that no white wound spots appeared on the incision, the staff reinserted the insert tube 2 back onto the flower pot 1, and the shade net composed of all the main shade nets 4 and all the auxiliary shade nets 5 with a shading rate of 70% continued to cover the cutting potted plants to create a weak light environment. When the staff observed that white wound spots appeared on the incision, it indicated that the incision of the orchid after the cutting had healed initially, and at this time the staff controlled the motor 2 2 drives the height adjustment screw rod 21 to rotate forward, and the height adjustment screw rod 21 drives the lifting slider 23 to move downward along the insertion tube 2. At the same time, the lifting slider 23 pulls the pull rope 25 to drive the counterweight slider 24 to move obliquely upward along the inclined rail 32, and the pull rope 25 pulls the auxiliary shade net 5 away from the top of the main shade net 4 and moves into the insertion tube 2, so that the top of the flower pot 1 loses the cover from the auxiliary shade net 5, and because the mesh density of the main shade net 4 is twice the mesh density of the auxiliary shade net 5, only the shade net with a shading rate of 45% formed by all the main shade nets 4 will cover the cutting potted plants, thereby improving the light intensity on the basis of the original weak light environment and accelerating the growth rate of the orchid after cutting.

[0043] On the fifth day after the shade net covered the cutting potted plants, the staff removed the insert tube 2 and the fixed frame 31, inclined rail 32, main shade net 4 and auxiliary shade net 5 connected thereto from the flower pot 1, and observed the leaves of the orchid of Li Shi for two hours. When the staff observed that the leaves of the orchid of Li Shi had curled, it meant that the orchid of Li Shi could not adapt to the strong light environment normally. At this time, the staff promptly reinserted the insert tube 2 back into the flower pot 1 and continued to cover the cutting potted plants with the shade net to create a weaker light environment. When the staff observed that the leaves of the orchid of Li Shi had curled, it meant that the orchid of Li Shi could not adapt to the strong light environment normally. When there is no wilting phenomenon in the leaves, the staff removes the cutting tube 2 and the fixed frame 31, the inclined rail 32, the main shade net 4 and the auxiliary shade net 5 connected to it from the flower pot 1 according to the rule of increasing the light time by two hours a day, and allows the orchid in the flower pot 1 to grow in a strong light environment according to the rule of increasing the light time by two hours a day, and gradually reduces the shading time of the orchid after cutting, so that the orchid after cutting can gradually adapt to the strong light environment. On the basis of meeting the application of a cutting propagation method of orchid of the present invention, an intelligent cultivation environment is provided for the cutting propagation of orchid of the present invention.

[0044] Example 2

[0045] On the basis of Example 1, Figures 1-6 As shown, each inclined rail 32 of this embodiment is rotatably connected to the corresponding fixing frame 31 via a rotating shaft; a torsion spring 33 is fixed between each inclined rail 32 and the corresponding fixing frame 31; and a stopper 34 is fixed to each inclined rail 32.

[0046] From 9:00 to 10:00 in the morning every day is the period of the highest humidity in a day, so at 9:00 in the morning every day, the motor 22 regularly drives the height adjustment screw rod 21 to rotate forward, and the height adjustment wire drives the lifting slider 23 to pull the pull rope 25 and the counterweight slider 24 to move diagonally upward along the inclined rail 32, and the pull rope 25 pulls the auxiliary shade net 5 away from the top of the main shade net 4 and moves toward the inside of the insertion tube 2. Then, when the counterweight slider 24 contacts the block 34, the counterweight slider 24 is blocked by the block 34 and cannot continue to move diagonally upward along the inclined rail 32. At this time, the lifting slider 23 that continues to move pulls the pull rope 25 to drive the counterweight slider 24 to push the inclined rail 32 to rotate upward around the axis of the rotating shaft connecting it to the fixed frame 31, and at the same time, the inclined rail 32 drives the torque The spring 33 twists, and the inclined rail 32 drives the main shade net 4 to tilt upward, so that there is a gap between the main shade net 4 and the flower pot 1 for air circulation, thereby improving the air circulation effect inside the flower pot 1 under a high humidity environment. When the time reaches ten o'clock in the morning, the motor 22 regularly drives the height adjustment screw rod 21 to rotate in the opposite direction, and the height adjustment screw rod 21 drives the lifting slider 23 to move upward to release the pull rope 25 outward. At this time, the twisted torsion spring 33 drives the inclined rail 32 and the main shade net 4 to flip downward and reset, and the counterweight slider 24 pulls the pull rope 25 under its own gravity to drive the auxiliary shade net 5 to move downward and reset, allowing the main shade net 4 and the auxiliary shade net 5 to return to the top of the flower pot 1 in time to provide shade for the orchid after cutting.

[0047] Example 3

[0048] On the basis of Example 1, Figures 1-6 As shown, an annular fan 6 is installed on the insert tube 2 of this embodiment; the air outlet of the annular fan 6 is connected to an air guide scoop 61 corresponding to the number and position of the main shade nets 4, and the air guide scoops 61 are respectively directed towards the corresponding main shade nets 4; an environmental detector 7 is installed on the insert tube 2.

[0049] Every morning, the environmental detector 7 monitors the air temperature and air humidity inside the flower pot 1. When the environmental detector 7 detects that the air temperature inside the flower pot 1 reaches 20°C or above, and the air humidity reaches 93% or above, dewdrops are likely to condense on the main shade net 4 and the auxiliary shade net 5, and the condensed dewdrops will destroy the air circulation effect of the main shade net 4 and the auxiliary shade net 5. At this time, the annular fan 6 is required to continuously blow low-flow airflow to each main shade net 4 and auxiliary shade net 5 through the air guide 61 to ensure that the main shade net 4 and the auxiliary shade net 5 have good air circulation effects.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
