Preferably, in the step A, the length of the sweet potato vine sections is 20-25 cm, and the sweet potato vine sections are at least provided with 3 leaves and at least 4 nodal positions.
Preferably, in the step B, the base fertilizer comprises the following components in parts by weight,
100 parts of manure, 40 parts of plant ash, 15 parts of diammonium hydrogen phosphate, 3 parts of ferrous sulfate and 3 parts of potassium chloride.
Preferably, in the step D, the drip irrigation device comprises a water supply pipeline, a plurality of drip pipe heads are installed on the water supply pipeline, cavities communicated with the water supply pipeline are arranged in the drip pipe heads, a plurality of support arms are hinged to the edge of the bottom of each cavity, elastic films are connected between the outer edges of the top ends of the support arms and the bottom of each cavity, the elastic films are fixed to the outer side faces of the support arms in a fit mode, at least two groups of through holes are formed in the side faces of each cavity, the through holes in the same group are located on the same horizontal plane, the through holes in the different groups are located on different cavities in different vertical directions, and a pressure release valve is installed in each through hole.
Preferably, the bottom of the cavity is connected with a conical barrel, the inner diameter of the conical barrel is gradually reduced from top to bottom, a suspension frame is fixed on the inner wall of the conical barrel, a connecting rod is fixed at the bottom of the suspension frame, two limiting plates are fixed on the connecting rod, a guide plate is movably sleeved on the connecting rod and located between the two limiting plates, the distance between the two limiting plates is larger than the thickness of the guide plate, the outer edge of the guide plate is in clearance fit with the inner wall of the conical barrel, the inner edge of the guide plate is in clearance fit with the connecting rod, a plurality of arc-shaped guide holes are formed between the top surface of the guide plate and the side surface of the guide plate, and one ends of the arc-shaped guide holes, which are located on the side surface of the guide plate, are capillary holes.
Preferably, a spring is connected between the bottom surface of the guide plate and the limiting plate positioned below the guide plate.
Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: the invention promotes the growth of the root system of the sweet potato by optimizing the planting process of the sweet potato, ensures that the sweet potato can absorb water and nutrient substances better and fully, and can further improve the yield of the sweet potato. The drip irrigation device further improves the utilization rate of drip irrigation water by improving the drip irrigation device. Firstly, a plurality of groups of through holes with pressure release valves are arranged on the side wall of the dropper head, when the drip irrigation coverage area needs to be enlarged, water flow can flow out through the through holes by increasing water supply pressure, and the purpose of flexibly adjusting the drip irrigation coverage area through the water supply pressure is achieved. As the water pressure is increased, the supporting arms can be inclined inwards under the action of the water pressure, so that the elastic film gradually blocks the water outlet sectional area of the dropper head to keep the water outlet quantity at the bottom of the cavity basically unchanged. Because the amount of the drip irrigation water is very small, the uniformity of the water outlet at the bottom of the cavity can not be well ensured particularly in a low water pressure state. Aiming at the problem, the invention installs the guide plate which can shift and rotate flexibly at the bottom of the cavity, when water flow drops on the guide plate, the guide plate can shift to one side of the water flow drop, meanwhile, the water flow enters the arc-shaped guide hole by gravity, because the end of the arc-shaped guide hole, which is positioned at the side of the guide plate, is a capillary channel, the water yield is low, a part of water can be stored in the arc-shaped guide hole temporarily, meanwhile, because the arc-shaped guide hole is arc-shaped, the water flow does not continue to flow along the vertical direction after entering the arc-shaped guide hole, but flows to one side along the arc-shaped guide hole, the gravity center of the whole guide plate can be changed, thereby realizing that the guide plate intermittently rotates under the driving of drip irrigation water, realizing the automatic change of the guide plate to the drip irrigation water flow guide direction of the drip irrigation pipe, and ensuring the uniformity of the drip irrigation. The spring additionally arranged on the bottom surface of the guide plate is used for improving the flexibility of deflection and rotation of the guide plate.
