Sowing machine capable of precision sowing and sowing method thereof

Abstract

The invention belongs to the field of sowing equipment, and particularly relates to a sowing machine capable of precision sowing and a sowing method thereof. The sowing machine comprises a plurality of hill-drop planters and multiple rows of plough frames; the hill-drop planters capable of rotating are mounted on the multiple rows of plough frames; and each hill-drop planter comprises a pluralityof precision seed taking devices, a plurality of sheet-shaped sowing movable hole nozzles, a plurality of soil-penetrating fixed hole nozzles, a vertically-arranged rotating wheel, two vertically-arranged fixed discs, a vertically-arranged rotating disc and a horizontally-arranged main fixed shaft. The hill-drop planters are placed on the multiple rows of plough frames in a staggered mode, the hill-drop planter structures capable of realizing high-density sowing and the application of the hill-drop planter structures in the field of high-density crop sowing are used for effectively solving theproblems that the reasonable planting density of high-density crops is difficult to realize due to non-uniform sowing density and non-uniform sowing depth of existing sowing equipment in the background art, the growth space of grain seedlings is non-uniform, and the illumination is non-uniform and the like, so that the yield of crops is directly influenced.

Description

technical field [0001] The invention belongs to the field of sowing equipment, and in particular relates to a precision sowing seeder and a sowing method thereof. Background technique [0002] The plan for a year lies in spring, sowing in spring and harvesting in autumn comes first. In agricultural production practice, whether the sowing process is done well or not has a great impact on the whole process of crop cultivation, including the amount of seeds used, water and fertilizer input, labor expenses and later output, etc., which ultimately affects the production efficiency of the year. [0003] The sowing of high-density crops such as wheat, millet, alfalfa and dry-sowed rice on the market now mainly adopts the dense sowing method of mechanical drill seeder, air suction drill drill or broadcast seeder. This sowing method ensures the planting density of such crops and also improves the land use efficiency. [0004] However, the existing sowing equipment such as mechanica...
