[0002] The karst rocky mountainous area is located in a relatively harsh environment, has a broken terrain, and a shallow soil layer (usually less than 30 cm), and has a high rock exposure rate, which leads to poor water and fertilizer retention capacity and easy water and soil loss. At the same time, during rainfall, the precipitation is concentrated but the evaporation is large, leading to dry local microclimate. Under strong light weather, the shade under the forest is insufficient, leading to the traditional reclamation aggravating the rocky desertification, and the ecological restoration and agricultural production need to be considered.

[0003] During the growth of polygonatum sibiricum, it likes a shady and weak light environment, and needs loose and fertile slightly acidic soil (pH 5.5-6.5) to avoid strong light direct radiation and water accumulation.

DETAILED DESCRIPTION

[0042] The technical scheme of the present application will be further described below in conjunction with the drawings and specific embodiments.

[0043] As shown in the drawings, Figure 1 The present application provides a kind of undergrowth of Huangjing in karst stone mountainous area ecological planting equipment, including planting and transporting assembly 1, one side of planting and transporting assembly 1 is equipped with the planting distance adjusting assembly 2 for adjusting Huangjing planting range;

[0044] One side of planting distance adjusting assembly 2 is equipped with the seedling transporting assembly 3 for outputting Huangjing seedling, the bottom of seedling transporting assembly 3 is equipped with the soil digging and fertilizing assembly 4 for transplanting Huangjing seedling, digging soil and fertilizing planting area, planting and transporting assembly 1 includes planting and transporting frame 101, rotating rod 102 is installed in the inside of planting and transporting frame 101 by first motor, positioning clamping block 103 is fixedly installed on the outside of rotating rod 102, first motor is fixedly installed on one side of planting and transporting frame 101, the output end of first motor is fixedly connected with rotating rod 102, one side of positioning clamping block 103 is equipped with inclination sensor, inclination sensor monitors the included angle of planting distance adjusting assembly 2, seedling transporting assembly 3 and ground in real time, then data transmission to controller, controller controls the operation of first motor, if the inclination angle of planting distance adjusting assembly 2 and seedling transporting assembly 3 and ground is too large, controller triggers adjustment instruction, first motor drives rotating rod 102 and positioning clamping block 103 to rotate and adjusts the angle of planting distance adjusting assembly 2 and seedling transporting assembly 3, in turn, it is convenient for planting distance adjusting assembly 2 and seedling transporting assembly 3 to keep vertical with ground when transplanting Huangjing seedling, digging soil and fertilizing planting area, which is conducive to the cultivation and growth of Huangjing.

[0045] As Figures 1-5 shown, the planting spacing adjustment assembly 2 includes two groups of transposition adjustment frames 201 fixedly installed on one side of the positioning clamping block 103, the top of the transposition adjustment frame 201 is fixedly installed with a forward and reverse motor 209, the output shaft of the forward and reverse motor 209 is fixedly installed with an auxiliary rotating rod 208, the side away from the forward and reverse motor 209 of the auxiliary rotating rod 208 is hinged with a horizontal sliding way 206, one side of the transposition adjustment frame 201 is fixedly installed with a sliding cavity frame 202, the inside of the sliding cavity frame 202 is slidingly installed with a positioning sliding block 203, the top of the positioning sliding block 203 is fixedly installed with a vertical sliding way 205, the horizontal sliding way 206 is slidingly installed on the outside of the vertical sliding way 205, the bottom of the horizontal sliding way 206 is fixedly installed with a planting positioning plate 204, the top end of the transposition adjustment frame 201 is fixedly installed with two limiting blocks 207, due to the broken terrain of the karst stone mountain area, the land soil layer is shallow, in order to avoid the close spacing between the planting points leading to excessive loss of fertilizer, then the output shaft of the forward and reverse motor 209 drives the auxiliary rotating rod 208 to rotate counterclockwise, it is explained here that the forward and reverse motor 209 moves the planting positioning plate 204 by the forward and reverse motor 209 is from top to bottom, moves within the limiting range of the two limiting blocks 207, avoids the seedling transmission assembly 3 on the planting positioning plate 204 from being disturbed by the ground when the planting positioning plate 204 is deflected and cannot continue to rotate, at the same time, the auxiliary rotating rod 208 drives the horizontal sliding way 206 to move along the vertical sliding way 205 first along the Y axis up and down, the force of the auxiliary rotating rod 208 on the horizontal sliding way 206 can be decomposed into two forces, one force is the tension along the vertical sliding way 205 direction Y axis, the other force is the thrust along the sliding cavity frame 202 direction X axis, so that the positioning sliding block 203 follows the deflection direction of the horizontal sliding way 206 to slide on the sliding cavity frame 202, so as to realize that the transposition process of the horizontal sliding way 206 driving the seedling transmission assembly 3 through the planting positioning plate 204 is guided and limited by the vertical sliding way 205 and the positioning sliding block 203, so that the seedling transmission assembly 3 adjusts the orientation more stably.

[0046] As Figures 4-6As shown, the seedling transmission assembly 3 includes four fixed mounting in one side of planting positioning plate 204 fixed clamping block 301, the inside of fixed clamping block 301 is fixedly installed with seedling transport pipe 303, the top of seedling transport pipe 303 is fixedly installed with seedling storage pipe 302, the outside of seedling transport pipe 303 is slidably installed with sliding cavity transmission pipe 304, the bottom of planting positioning plate 204 is fixedly installed with first hydraulic telescopic rod 305, the bottom of first hydraulic telescopic rod 305 is fixedly installed with fixed clamping plate 306, fixed clamping plate 306 is fixedly installed on the outside of sliding cavity transmission pipe 304, the bottom of fixed clamping plate 306 is fixedly installed with second hydraulic telescopic rod 307, the bottom of second hydraulic telescopic rod 307 is fixedly installed with slide plate 308, slide plate 308 is slidably installed on the outside of sliding cavity transmission pipe 304, the bottom of excavating and fertilizing assembly 4 is rotatably installed with second gear 407, the outside of sliding cavity transmission pipe 304 is rotatably installed with annular fixed block 410, annular fixed block 410 is detachable on first gear 406, the top of annular fixed block 410 is fixedly installed with first gear 406, first gear 406 is arranged in meshing state with second gear 407, one side of slide plate 308 is provided with arc-shaped track 309, one side of first gear 406 is provided with arc-shaped hole matched with arc-shaped track 309, the outside of sliding cavity transmission pipe 304 is provided with vertical track 310, the bottom of slide plate 308 is fixedly installed with auxiliary push rod 403, it is further stated that the inside of seedling storage pipe 302 can be filled with seedlings of rhizoma polygonati, and a control unit is installed in the inside of seedling storage pipe 302, the staff outputs or stops the output of seedlings of rhizoma polygonati to the four seedling transport pipes 303 through the control unit, the control unit controls the release or closing of seedlings of rhizoma polygonati in the four seedling transport pipes 303 by seedling storage pipe 302, when adjusting the planting spacing of seedlings of rhizoma polygonati according to the regional state of karst rocky mountain forest, if the planting spacing requirement is small, the planting positioning plate 204 is in a fixed position, and the four seedling transport pipes 303 simultaneously transport seedlings of rhizoma polygonati, if the planting spacing requirement is general, for example, the first seedling transport pipe 303 releases seedlings of rhizoma polygonati, while the second and third seedling transport pipes 303 stop the release of seedlings of rhizoma polygonati, if the planting spacing requirement is large, the planting positioning plate 204 stays at the first position, and the first seedling transport pipe 303 releases seedlings of rhizoma polygonati, then the planting positioning plate 204 is driven to stay in the opposite direction through the auxiliary rotating rod 208 and the horizontal slide 206, at this time, the spacing between the original planting positioning plate 204 position and the present planting positioning plate 204 position is maximum, so the fourth seedling transport pipe 303 of the present planting positioning plate 204 can release seedlings of rhizoma polygonati at this time, thereby adapting to the condition of large planting spacing, so that the planting spacing is adjusted according to environmental factors better, compared with the traditional small and medium-sized planting equipment which needs to frequently change position for planting rhizoma polygonati, the present equipment has higher efficiency and smaller size, it is stated that before planting according to the regulations,First, the unused ring-shaped fixed block 410 and the delivery short tube 413, hollow excavating arc block 409 and other components are removed from the sliding cavity transmission pipe 304 to avoid the appearance of unnecessary plant pits when the sliding cavity transmission pipe 304 moves downward.

[0047] The planting pit spacing is adjusted to avoid the "fertilizer damage runoff" caused by rainwater erosion in traditional technology, and the dispersed fertilization makes the nutrients more evenly penetrate into the deep soil, reducing the risk of fertilizer carried by runoff.

[0048] When the planting and transporting assembly 1 drives to the fixed area for planting of rhizoma polygonati, the telescopic rod mechanism of the first hydraulic telescopic rod 305 extends outward, the fixed clamping plate 306 follows the telescopic rod along the outer surface plate of the seedling transportation pipe 303 to drive the sliding cavity transmission pipe 304 to move downward, until the sliding cavity transmission pipe 304 moves to the fixed position to be able to put the seedlings.

[0049] As Figures 6-10As shown, the bottom of the auxiliary push rod 403 is provided with a conveying short pipe 413 capable of sliding and rotating inside the auxiliary push rod 403, and a rubber telescopic pipe with telescopic characteristics is rotatably installed at the connection between the conveying short pipe 413 and the sliding cavity transmission pipe 304, so as to block the gap between the conveying short pipe 413 and the sliding cavity transmission pipe 304, avoid the rhizoma polygonati seedlings or rhizomes from falling into the gap when being put, and the outer side of the conveying short pipe 413 is hingedly connected with a plurality of L-shaped clamping plates 408 through a positioning ring 404 fixedly installed on the outer wall of the side of the conveying short pipe 413 passing through the sliding cavity transmission pipe 304, a bending rod 405 is hingedly connected between the annular fixed block 410 and the L-shaped clamping plate 408, a hollow digging arc block 409 is fixedly installed at the bottom of the L-shaped clamping plate 408, and the digging and fertilizing assembly 4 further comprises a fertilizer mixing box 401 fixedly installed on the outer side of the sliding cavity transmission pipe 304, a conveying pipe 402 fixedly installed at the bottom of the fertilizer mixing box 401, a pipeline connecting block 412 fixedly installed on one side of the hollow digging arc block 409, and the conveying pipe 402 is fixedly and installed at one end of the arc-shaped hole of the sliding plate 308 and the pipeline connecting block 412, and a transmission hole 411 in communication with the pipeline connecting block 412 is formed in the inner wall of the hollow digging arc block 409.

[0050] Meanwhile, the third motor fixedly installed at the bottom of the slide plate 308 drives the second gear 407 to rotate, the second gear 407 drives the first gear 406 to rotate by 10-20 degrees, the first gear 406 drives the four groups of hollow soil digging arc blocks 409 to synchronously rotate through the annular fixed block 410, since the hollow soil digging arc blocks 409 are opened with slits and cannot completely loosen the soil, the hollow soil digging arc blocks 409 rotate a small distance, which facilitates better soil loosening and is beneficial to fertilization, it is explained that the arc-shaped track 309 and the arc-shaped hole are arranged to enable the conveying pipe 402 to rotate a small distance along with the hollow soil digging arc blocks 409, the third motor is a forward and reverse motor, which can restore the hollow soil digging arc blocks 409 to the original position and avoid the problem of pipeline winding, and the conveying pipe 402 has the flexibility, which can also adjust the flexibility according to the change of the hollow soil digging arc blocks 409;

[0051] When the hollow soil digging arc blocks 409 are in the open state, the transmission holes 411 enlarge the spraying range of the planting pits, along with the mixed fertilizer in the fertilizer mixing box 401 being spread to the periphery of the planting pit through the conveying pipe 402 and the pipe connecting block 412, the pesticide concentratedly sprayed by the fertilizer mixing box 401 is diffused outward, which is beneficial to the absorption of the fertilizer by the rhizoma polygonati, and when the hollow soil digging arc blocks 409 are closed, the soil is located at the side of the hollow soil digging arc blocks 409 away from the transmission holes 411 and is blocked by the outer wall of the hollow soil digging arc blocks 409 and cannot be in contact with the transmission holes 411, thereby avoiding the blockage of the transmission holes 411 and improving the circulation efficiency of the fertilizer;

[0052] The existing fertilization method is to directly put the fertilizer into the planting pit, and the dispersed fertilization can reduce the concentration of acid substances (such as acid ions generated by the decomposition of ammonium sulfate) in single-point soil, slow down the leaching speed of alkaline ions such as calcium and magnesium, and maintain the stability of the soil colloidal structure; after being dispersed, the roots or seedlings of the rhizoma polygonati are more likely to contact the nutrients, and the "root burning" or nutrient waste caused by the local high concentration is reduced.

[0053] Specifically, the under-forest rhizoma polygonati ecological planting method in a karst stone mountainous area comprises the following steps:

[0054] S1: selecting a natural secondary forest with a slope of ≤25° and a soil layer thickness of ≥20 cm as a planting area, retaining the original vegetation shade (transmittance of 30%-50%), adjusting the stand to thin the dense forest trees, and retaining the scattered trees to form natural shade;

[0055] S2: The staff mixes the humic acid type water-soluble fertilizer and the water retaining agent in the inside of the fertilizer mixing box 401, and starts the planting transportation assembly 1 to drive to the specified planting area, and the tilt sensor monitors the included angle between the planting interval adjusting assembly 2, the seedling transportation assembly 3 and the ground in real time, the angle of the planting interval adjusting assembly 2 and the seedling transportation assembly 3 is adjusted through the first motor, so that the planting interval adjusting assembly 2 and the seedling transportation assembly 3 are kept vertical to the ground when transplanting the seedlings, digging soil and planting the fertilizer planting area;

[0056] S3: The staff adjusts the seedling planting interval of the seedlings according to the planting interval requirement, outputs the seedlings or stops outputting the seedlings through the control unit to the four seedling transportation pipes 303, rotates the auxiliary rotating rod 208 through the output shaft of the forward and reverse motor 209, and adjusts the seedling planting interval of the seedlings through the planting positioning plate 204 according to the area state of the karst stone mountain area forest;

[0057] S4: The first hydraulic telescopic rod 305 drives the sliding cavity transportation pipe 304 to move downward through the fixed clamping plate 306, the hollow soil digging arc block 409 is inserted into the surface soil to a fixed depth, the sliding plate 308 is driven to rise a distance along the sliding cavity transportation pipe 304 through the extension of the telescopic rod mechanism of the second hydraulic telescopic rod 307, the L-shaped clamping plate 408 is deflected upward under the limiting of the bending rod 405, and then the four groups of hollow soil digging arc blocks 409 are expanded outward from the sealed state to form a planting pit on the ground;

[0058] S5: The first gear 406 drives the four groups of hollow soil digging arc blocks 409 to rotate synchronously through the annular fixed block 410, the hollow soil digging arc blocks 409 rotate a small distance to loosen the soil, and the mixed fertilizer in the fertilizer mixing box 401 is spread to the four sides of the planting pit through the conveying pipe 402 and the pipe connecting block 412, and then the pesticide concentratedly sprayed by itself is diffused outward;

[0059] S6: The micro-spraying belt is laid in the planting area, the micro-spraying belt is a water mist spraying device, which realizes water-saving irrigation in cooperation with the timer, irrigates the planting area within a specified time, drips 2 times per week for 15 minutes in the dry season, and closes the water mist spraying device in the rainy season, and then uses rainwater for irrigation, so as to help water saving, and the humic acid type water-soluble fertilizer and the water retaining agent are mixed and applied to the root zone.
