Description

Technical Field

[0001] This invention relates to the field of agricultural planting, and in particular to a method for planting sweet potato seedlings in a series of cascading arrangements. Background Technology

[0002] Sweet potatoes are a nutritious root vegetable with high nutritional value, widely cultivated and consumed globally. Sweet potatoes are typically planted using a raised bed planting method. Before planting, select high-lying, well-drained, deep, fertile, and loose soil, and deep plow and harrow the soil to break it up and loosen it. Then, create raised beds, which facilitates drainage and the growth of sweet potato tubers. Select disease-free sweet potato seedlings with robust stems, short internodes, and 5-7 nodes. Insert the seedlings into the middle of the raised bed, with the spacing depending on the variety and soil fertility. Water promptly after planting to improve the survival rate.

[0003] Currently, single-plant planting is typically done manually or using semi-automatic transplanters. Manual planting on a large scale incurs high labor costs, and the precision in controlling planting depth and spacing is poor. Semi-automatic transplanters require manual assistance in delivering the seedlings, necessitating cooperation between the driver and the delivery personnel. Furthermore, to ensure proper planting, the transplanter's speed is usually slow. While this reduces labor intensity, it offers limited improvement in planting efficiency. Considering the equipment and maintenance costs of semi-automatic transplanters, they offer little advantage over manual planting. Therefore, it is necessary to improve the traditional single-plant planting method and develop a more efficient sweet potato planting method. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a method for planting sweet potato seedlings in a series of interconnected rows.

[0005] The technical solution of this invention is: a method for planting sweet potato seedlings in a series of interconnected rows, comprising the following steps:

[0006] ① Use weaving equipment to weave sweet potato seedlings at equal intervals between two parallel ropes to form rope ladder-shaped sweet potato seedlings. The length of these rope ladder-shaped sweet potato seedlings depends on the planting needs. ② One rope is woven and fixed in the middle of the sweet potato vine segment, and another rope ladder is woven and fixed at the end of the segment;

[0007] ③ Select land with deep, loose and well-aerated soil for deep plowing, and then use a ridging machine to create ridges on the surface; ④ During or after ridging, dig planting trenches on the surface of the ridge, and the cross-section of the planting trenches is trapezoidal.

[0008] ⑤ Lay the rope ladder-shaped sweet potato seedlings into the planting furrows on the ridge, with the seedling heads extending out of the planting furrows, and the size of the sweet potato seedling nodes matching the size of the planting furrows; ⑥ Cover the planting trench with soil, burying the nodes of the sweet potato seedlings into the ridge, with the seedling heads protruding from the ridge surface.

[0009] Preferably, the rope is made of at least two braided ropes spirally wound together.

[0010] Preferably, the braided rope is a paper rope, which has weak corrosion resistance and is easily decomposed in the soil.

[0011] Preferably, the stems of the rope-ladder-shaped sweet potato seedlings are laid flat in the planting trench.

[0012] Preferably, the stems of the rope-ladder-shaped sweet potato seedlings are laid obliquely into the planting trench.

[0013] Preferably, the length of the sweet potato vine stem buried in the ridge is 15-18cm.

[0014] Preferably, the distance between the sweet potato seedlings between the two parallel ropes is 15-20 cm.

[0015] Preferably, the thickness of the soil covering is 3-5 cm.

[0016] Preferably, the weaving equipment is mounted on a tractor, which carries the weaving equipment as it travels between the rows. After the rope-ladle-shaped sweet potato seedlings are woven, they are directly laid into the planting trench.

[0017] Preferably, the weaving equipment processes the rope ladder-shaped sweet potato seedlings in a production line manner in the processing workshop. The processed rope ladder-shaped sweet potato seedlings are wound into rolls and then planted by unwinding and laying them out.

[0018] The beneficial technical effects of this invention are as follows: This invention weaves sweet potato seedlings at equal intervals between two parallel ropes to form a rope ladder-shaped sweet potato seedling. Planting trenches are set on the ridge, and the rope ladder-shaped sweet potato seedlings are laid as a whole into the planting trenches for planting. This method can densely and efficiently place the sweet potato seedlings into the planting trenches. After covering with soil, the sweet potato planting is completed. This method of laying the seedlings as a whole is more efficient than the traditional method of planting one seedling per hole. The efficiency improvement is even more obvious when planting sweet potatoes on a large scale. Attached Figure Description

[0021] Example 1, see appendix Figure 1-5 A method for planting sweet potato seedlings by cascading them together, with the following planting steps:

[0022] ①Use weaving equipment to weave sweet potato seedlings 11 at equal intervals between two parallel ropes 12 to form a rope ladder-shaped sweet potato seedling 01; ② One rope 12 is woven and fixed in the middle of the section 111 of the sweet potato seedling 11 to prevent the leaves of the seedling from being woven into the rope 12, and another rope ladder is woven and fixed at the end of the section 111.

[0023] ③ Select land with deep, loose and well-aerated soil for deep plowing, and then use a ridging machine to create ridges on the surface; ④ During or after ridging, dig planting trenches 22 on the surface of the ridge body 02. The sweet potato trenches are horizontal or sloping trenches.

[0024] ⑤ Lay the rope ladder-shaped sweet potato seedlings 01 into the planting furrows 22 on the ridge 02, with the seedling heads of the sweet potato seedlings 11 extending out of the planting furrows 22; ⑥ Cover the planting trench 22 with soil 21, and the stems 111 of the sweet potato seedlings 11 are buried in the ridge 02, with the seedling heads protruding from the ridge surface of the ridge 02.

[0025] The stems 111 of the rope ladder-shaped sweet potato seedlings 01 are laid flat in the planting trench 22. The horizontal bottom trench corresponds to the flat laying planting method. After the soil covering 21 of the sweet potato seedlings 11 is pressed, it contacts the horizontal bottom of the planting trench 22, forming a flat planting of the seedlings. Alternatively, they can be laid obliquely in the planting trench 22. The oblique bottom trench corresponds to the oblique laying planting method. After the soil covering 21 of the sweet potato seedlings 11 is pressed, it contacts the oblique bottom of the planting trench 22, forming an oblique planting of the seedlings.

[0026] In arid regions such as mountainous areas, sweet potatoes are planted at an angle, which allows the roots to absorb water from deeper soil layers, preventing water shortages and yield reductions due to drought. Furthermore, the increased depth of the stem insertion (111) promotes the production of large, round sweet potatoes. In areas with ample rainfall or good irrigation, flat planting is used. This shallower planting depth prevents water shortages and promotes the production of slender sweet potatoes; one plant can bear approximately 13 fruits. Specific planting methods can be tailored to regional differences and the desired shape and size of the sweet potatoes.

[0027] The length of the sweet potato vine stalk 111 buried in the ridge 02 is 15-18cm. The spacing between the sweet potato vines 11 between two parallel ropes 12 is 15-20cm, which means the plant spacing of the sweet potatoes is 15-20cm. The thickness of the soil covering 21 is 3-5cm. The burial length, plant spacing, and soil covering 21 of the sweet potato vines 11 can be adjusted according to regional differences and needs within the above-mentioned size range.

[0028] The weaving equipment is mounted on a tractor, which travels between rows carrying the weaving equipment. After the rope-ladder-shaped sweet potato seedlings 01 are woven, they are directly laid into the planting furrows 22. In this method, the weaving equipment works in the field with the tractor, and the seedlings are woven and laid for planting simultaneously. This method is greatly affected by weather conditions. Alternatively, the weaving equipment processes the rope-ladder-shaped sweet potato seedlings 01 in a processing workshop using an assembly line. The processed rope-ladder-shaped sweet potato seedlings 01 are wound into rolls and then laid for planting by unwinding the rolls. In this method, the seedlings are first woven into rolls in the production workshop and then planted using the rolls. This method is less affected by weather conditions.

[0029] Example 2, see appendix Figure 6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the rope body 12 is made of at least two braided ropes 121 spirally wound together, so that the stems 111 of the sweet potato seedlings 11 can be woven and fixed in the spiral gap between the braided ropes 121. The braided ropes 121 are paper ropes, which can decompose quickly after being buried in the soil with the seedlings, so as to avoid affecting the normal development and growth of the sweet potato roots.
