Background
Sweet potatoes are also called sweet potatoes, sweet potatoes and sweet potatoes, are barren-resistant, drought-resistant, strong in adaptability and high in yield, the cultivation area and the yield of the sweet potatoes in China are only second to those of rice, wheat and corn, and the sweet potatoes play an important role in agricultural planting structures and grain crop production in China.
However, the transplanting method of the sweet potato seedlings in production has important influence on the yield of the sweet potatoes. The direct planting method, the oblique planting method and the flat planting method are three transplanting methods commonly used in agriculture. The direct planting method is characterized in that seedlings are vertically planted in soil, and the number of sweet potatoes planted is small; the oblique planting method is to obliquely plant the seedlings in soil, and the planted sweet potatoes are uneven in bearing; the horizontal planting method is that seedlings are horizontally paved and inserted in soil, the planted sweet potatoes bear more potatoes and are uniform in size, and the method is mostly adopted in large-scale high-yield fields. The method of horizontal planting generally requires that the sweet potato seedlings have about 20 years ~ 30cm, and each section of the seedlings inserted into the soil is distributed in a shallow soil layer with the depth of about 5cm below the soil surface. In the process of flat planting on ridges, when seedlings and furrows are required to be planted in parallel, a section with leaves at the head of each seedling is bent upwards to be exposed out of the ground for growth, and the whole seedlings are in a L shape; when seedlings are required to be flatly planted in the direction vertical to the ridge, one section with leaves at the head of each seedling is exposed in the ridge, the seedlings do not need to be bent, the seedlings are flatly laid on a shallow trench with the depth of about 5cm on the ridge and then covered with soil, and the seedlings can be flatly planted on two sides of the ridge respectively. No matter the seedling is in parallel with the furrow direction or in perpendicular with the furrow direction, the manual operation has large labor demand, low efficiency and high cost, and the busy season usually delays farming season. Most of the existing transplanting machines are used for directly planting seedlings, and practical sweet potato flat planting operation machines are lacked. To this current situation, the utility model provides a wide ridge double row sweet potato flat planting machine, this machine straddle can accomplish in succession when moving ahead on the soil ridge and get the seedling, send the seedling, ditching, spread seedling and earthing operation, with seedling and the perpendicular flat planting of furrow direction on the soil ridge both sides, and expose one section of seedling head bandeau leaf in the furrow, realize wide ridge double row sweet potato flat planting high-efficient operation.
