[0002] Sugarcane is a perennial tall solid herb with strong and well-developed rhizomes. Sugarcane is generally planted in trenches, with the sugarcane stems planted in trenches of a certain depth (20-25cm) to facilitate fertilization and soil management in the later stage. However, planting sugarcane stems in trenches can easily lead to problems such as poor drainage.

[0003] Guangxi is the main sugarcane producing area, with an annual sugarcane planting area of ​​about 11.5 million mu, of which at least one-third of the sugarcane is planted in paddy fields with high groundwater levels and poor drainage, or in waterlogged areas such as flat land and low-lying land. At the same time, most of the sugarcane planting in Guangxi is in winter and spring, and the budding and seedling stages, which are very sensitive to temperature, humidity, light and air, generally coincide with the spring with frequent rains. Rainwater often soaks the sugarcane stems in the planting ditch, affecting the germination and later growth of the sugarcane stems, resulting in low germination rate, few effective stems, and substandard yields.

[0004] In order to solve the problem of waterlogging in sugarcane fields that affects the germination and later growth of sugarcane seed stems, and to facilitate the management of fertilization and soil cultivation in the later stage, a two-level ridge and three-level furrow sugarcane planting method is studied. That is, a two-level ridge planting furrow is opened in the same direction on the oblique side of the existing planting furrow for sugarcane planting. However, the current sugarcane planting machines all plant sugarcane seed stems in the first-level planting furrow, such as patent CN114365610B, which is not suitable for two-level ridge and three-level furrow sugarcane planting.

The bottom of the planting trough 61 near the drainage ditch of the primary ridge is inclined, and the depth gradually becomes shallower from the middle of the planting trough 61 to the open end. That is, after the sugarcane is planted, the soil can be automatically returned through the inclined gap at the rear end. Specifically, the planting trough 61 includes a first trough plate 611, a second trough plate 612 and a third trough plate 613. The first trough plate 611 is parallel to the drainage ditch of the primary ridge, one end of the second trough plate 612 is connected to the first trough plate 611, and the other end is connected to the third trough plate 613.

The diaphragm 63 is provided with the fertilizer conduit 64 away from the opening end, and the outlet end of the fertilization device is connected to the fertilizer conduit 64. The first slot plate 611 and the second slot plate 612 at the front end of the diaphragm 63 are deeper than the rear end, and the bottom depth of the fertilizer conduit 64 is deeper than the bottom depth of the first slot plate 611 near the opening end. That is, the front part of the planting trough 61 is deeper, and a layer of loose soil can be formed below the sugarcane planting ground. At the same time, fertilizer is applied to the loose soil at the bottom before planting sugarcane, which is beneficial to the germination and later growth of sugarcane. Preferably, the fertilizer conduit 64 has two fertilizer outlets, one of which is located in the middle of the fertilizer conduit 64 and the other is located at the bottom of the fertilizer conduit 64. Two fertilizer conduits 64 of different diameters can be provided, the upper fertilizer conduit 64 having a larger diameter and the lower fertilizer conduit 64 having a smaller diameter, and the lower end opening is inclined, so that part of the fertilizer can be applied to the soil surface and the other part can be applied to the deeper soil of the sugarcane. After soiling by the soiling device 7, the fertilizer is respectively located on the surface layer of the sugarcane seed stem and at the deeper bottom, so that the fertilizer can be applied in layers, which is more conducive to the growth of the sugarcane seed stem.
