[0026] The present invention is further described in detail below in conjunction with specific implementations and in conjunction with the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0027] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0028] A high-yield planting device for yam, such as Figures 1 to 3As shown, yam seedlings 7 are planted at the highest point of the ridge body 5, including an arch frame 2 and a ground film 3; the arch frame 2 is arranged on one side of the yam seedlings 7, and is composed of a plurality of mutually intersecting frame units 4, and the frame unit 4 is an arch structure with a bottom width of 40 to 80 cm and a height of 30 to 60 cm. Specifically, the frame unit 4 has a bottom width of 60 cm and a height of 40 cm, and its two ends are inserted into the soil to a depth of 15 to 20 cm. Specifically, the material of the frame unit 4 can be long strips of bamboo, and usually the selected long strips of bamboo are 1.5 meters long and 1 to 2 cm wide. Bamboo is a natural material, which is easy to obtain and environmentally friendly. Compared with the prior art, the arch frame 2 is constructed with bamboo, which uses much less material and reduces the material cost of planting. Since the arch frame 2 is not high, the manpower consumed in the process of constructing the frame and harvesting the yam is significantly reduced, which effectively saves labor costs. The frame units 4 are intertwined with each other, and since the arch frame 2 itself is not high, the overall structure of the arch frame 2 is stable, which can effectively avoid the situation of lodging, and can also effectively limit the growth height of the above-ground yam vines and leaves, thereby increasing the yield of yam and increasing farmers' income. The side of the ridge body 5 away from the arch frame 2 is the first ridge surface 6, and the ground film 3 is a silver-black double-sided ground film, which covers the surrounding of the first ridge surface and on the bed surface 8 10 to 15 cm away from the yam seedlings, leaving a certain growth distance for the yam seedlings. The silver-black double-sided ground film can suppress weeds and also has the effect of controlling growth. The vine leaves that fall on the silver-black double-sided ground film are easily scalded and withered to death, effectively controlling the growth range of the yam seedlings and achieving the effect of controlling growth. Preferably, the ground film 3 is a silver-black double-sided ground film with a thickness of 0.01 to 0.012 mm. There is no need for manual pruning to control growth to increase the yield of yam. Compared with the traditional trellis method, the solution of the present application saves more manpower and reduces planting costs.

[0029] Specifically, the arched frame 2 can be adjusted according to the temperature conditions at the time of planting. When the temperature is low, in order to promote the growth of vines and leaves, the distance between the arched frame 2 and the ground film 3 can be set longer, and the arched frame 2 can also be tilted toward the rear walkway to make the vines and leaves close to the land to promote the growth of the aboveground vines and leaves; when the temperature is high, the distance between the arched frame 2 and the ground film 3 can be set shorter, so that the overly vigorous vines and leaves fall on the silver-black double-sided ground film and are scalded and withered to death, so as to control the overgrowth of the aboveground part and increase the yield of yam. The above-mentioned planting device is used to plant yam, and the field management is simple and no manual pruning is required. The rest is managed by conventional yam planting, and high-yield yam can be harvested. Specifically, the yam seedlings 7 can be planted in the middle of the frame unit 4, and the frame unit 4 is symmetrical about the yam seedlings 7.

[0030] In some other examples of this embodiment, the first ridge surface 6 of the ridge body 5 is sloped, and an oriented groove 1 is set at a depth of 10 to 18 cm from the first ridge surface. The slope of the oriented groove 1 matches the slope of the first ridge surface 6. The top of the oriented groove 1 corresponds to the highest point of the ridge body 5 (i.e., the ridge top). Correspondingly, a plastic film (not shown in the figure) is laid on the surface of the oriented groove 1. The thickness of the plastic film is 0.5 to 0.8 mm, and the Chinese yam cannot penetrate the plastic film. Specifically, when planting Chinese yam, a oriented groove 1 is dug downward from the ridge top along the first ridge surface 6 according to a certain spacing, and then the cut plastic film is laid in the oriented groove 1, and a small amount of fine mud is used to press the film along the direction of the oriented groove 1, and the film is semicircular. The oriented groove 1 provides space for directional growth of Chinese yam, so that the Chinese yam grows relatively straight, and it is also convenient for the Chinese yam to be harvested after maturity. Specifically, the width of the directional groove 1 is 8-12 cm, the depth is 12-18 cm, and the length is 1.0-1.2 m. Preferably, the width of the directional groove 1 is 10 cm, the depth is 15 cm, and the length is 1.2 m. Specifically, the slope angle of the first ridge surface 6 is 10°-15°. Since Chinese yam has the characteristic of growing downward, its lateral growth is guided by an oblique angle to reduce the difficulty of harvesting Chinese yam. The size of the slope angle can be determined according to the planting depth of Chinese yam.

[0031] In some other examples of the present embodiment, a first layer of fine soil of a certain thickness is arranged on the plastic film, organic fertilizer is arranged on the first layer of fine soil, and a second layer of fine soil of a certain thickness is arranged on the organic fertilizer, so as to provide sufficient fertilizer for the growth of yam. Moreover, the organic fertilizer is softer than soil and is more conducive to the growth of yam in the length direction. The second layer of fine soil can also shield the organic fertilizer to prevent the organic fertilizer from being lost due to water erosion, thereby extending the effective time of the organic fertilizer and increasing the yield of yam.

[0032] Specifically, a planting experiment was conducted in which the same variety of yam seedlings were planted on 150 mu of sloping land using the same cultivation method of laying plastic film in a directional trough, using two scaffolding methods, bamboo pole scaffolding and the above-mentioned arch scaffolding, and the same conventional management. Three sample points were randomly selected for sampling and yield measurement for the two scaffolding methods, each with an area of ​​about 14 square meters. The number of yam plants was counted, yam tubers were dug, the mud and sand impurities attached to the tubers were cleaned, the fresh weight of the tubers was weighed, and the fresh weight of the yam tubers of the three sample points of each variety was averaged, and the fresh weight of the tubers per mu was calculated from the average single plant yield. The per-acre yield of bamboo elevated frame is 2138.3±162Kg, and the per-acre yield of bamboo arch frame is 2498.2±206Kg, which is 16.8% higher than that of bamboo elevated frame. Converted into output value, based on the unit price of 7 yuan / kg, the per-acre output value of yam cultivated on bamboo elevated frame is 14,968.3 yuan, and the per-acre output value of yam cultivated on bamboo arch frame is 17,487.2 yuan. The per-acre output value of bamboo arch frame is 2,518.9 yuan more than that of bamboo elevated frame. The per-acre yield cost of bamboo elevated trellis is higher than that of bamboo arch trellis. The material and labor costs of the trellis are high, and the cost of harvesting yam is also relatively high. After calculation, the economic benefit of bamboo elevated trellis is 10,270.7 yuan / mu, and the economic benefit of bamboo arch trellis is 13,257.6 yuan / mu. The arch trellis cultivation increases income by 29.1% compared with bamboo elevated trellis. It can be seen that bamboo arch trellis can effectively avoid lodging due to its higher stability, effectively limit the growth height of the above-ground vines and leaves, help increase the yield of yam tubers, reduce costs and increase economic benefits.

[0033] Specifically, a second planting experiment was also conducted, using an arched frame of the same height and covering the bed surface with the same silver-black double-sided mulch film. Branches were added to the first piece of mulch film, and most of the vines and leaves fell on the branches. This is a common operation in the industry and is used to cool the vines and leaves. The only difference in the second piece of land was that branches were added to the mulch film. After the experiment, it was obvious that the vines and leaves in the second piece of land were too vigorous, and the yield of the second piece of land was even lower at the time of the final harvest. It can be seen that in the process of planting yam, the arched frame and the planting device of silver-black double-sided mulch film can effectively control the vigorous growth, so that the yam yield is higher.
