Bulldozing and film-covering seeding machine for saline-alkali soil sorghum

Abstract

The invention discloses a bulldozing and film-covering seeding machine for saline-alkali soil sorghum and belongs to a seeding machine. The bulldozing and film-covering seeding machine structurally comprises a rack, a bulldozing device, a seeding device, a film covering device, a soil covering blade, a film pressing device, an on-film earthing device and an on-film soil pressing device, wherein the bulldozing device, the seeding device, the film covering device, the soil covering blade, the film pressing device, the on-film earthing device and the on-film soil pressing device are sequentially arranged on the rack from back to forth, a traction frame is arranged at the upper part of the front end of the rack, and land wheels are respectively arranged at two sides of the lower part of the rack at the rear side of the bulldozing device. compared with the prior art, the saline-alkali soil sorghum bulldozing and film-covering seeding machine disclosed by the invention has the characteristics of reducing the salinity and the alkalinity of soil for seed germination of saline-alkali soil, improving the adaptability of initial soil conditions of sorghum seeds, increasing the emergence rate of sorghum, and improving the emergence quality; a seedling discharging-free technology plays a role in simplifying the cultivation and saving manpower and material resources.

Description

technical field [0001] The invention relates to a sorghum planter, in particular to a sorghum bulldozing film-covered sorghum planter in saline-alkali land free of seedlings. Background technique [0002] At present, the sorghum sowing in saline-alkali land is basically carried out by general-purpose field machinery. The problem of seedling raising is solved by preparing the soil, rowing, sowing, and mulching. Although this method can also complete the sowing work of sorghum on saline-alkali land, However, due to the transpiration of water in saline-alkali land, the soil surface has the characteristics of returning to salt, so the saline-alkali content of the soil surface is relatively high, which reduces the emergence rate and quality of sorghum, and requires manual release of seedlings, increasing labor costs. [0003] Currently, there is no good solution. Contents of the invention [0004] The technical task of the present invention is to provide a kind of saline-alkal...
