Problems solved by technology

The method of flat stubble covering is used because the wheat stubble is flat on the ground. If the sprinkler irrigation method is used, most of the fertilizer will be sprayed on the surface of the wheat stubble, resulting in a waste of fertilizer. There is no fertilizer and water drip irrigation cultivation device for no-tillage and flat stubble precision sowing of corn in the technology

Abstract

The invention provides a fertilizer water drip irrigation cultivation device and method for no-tillage stumping precision seeding of corn. The fertilizer water drip irrigation cultivation device comprises a supporting frame, a fertilizer tank is fixed to the supporting frame, a rectangular frame is fixed to one end of the supporting frame, and a distance adjusting mechanism used for adjusting the distance between a plurality of moving parts is fixed in the rectangular frame; each moving part is connected with a drip irrigation mechanism, each drip irrigation mechanism comprises a rigid water pipe, one end of each rigid water pipe is connected with a water outlet of the fertilizer tank, the other end of each rigid water pipe penetrates through the corresponding moving part to be connected with the side wall of a disc through a circumferential sliding assembly, and a drip irrigation nozzle is fixed to each disc and connected with the corresponding rigid water pipe through a connecting hose; and a pitching angle adjusting mechanism is fixed on the rectangular frame and is used for driving the first rotating shaft and the plurality of drip irrigation mechanisms to rotate synchronously. In order to ensure better absorption of water and fertilizer by root systems, the distance adjusting mechanism is arranged to adjust the distance between the plurality of drip irrigation mechanisms, so that the applied fertilizer can be accurately dropped into the absorption range of corn root systems.

Description

technical field [0001] The invention belongs to the technical field of corn planting, and in particular relates to a no-tillage, flat stubble, precision sowing, fertilizer and water drip irrigation cultivation device and method for corn. Background technique [0002] In recent years, the conservation tillage mode has been applied and promoted more and more, and no-tillage corn seeding is the core part of conservation tillage, which plays a decisive role in the overall tillage mode. Maize mechanized no-tillage precision sowing is a sowing method popular among farmers. The promotion of no-tillage sowing technology can realize water storage, moisture conservation, and soil fertility, which is conducive to the growth and development of corn and increases corn yield. [0003] In my country's wheat and corn double-cropping area, the processing methods of wheat stubble are flat stubble, vertical stubble, and stubble removal. Wheat stubble mulching, especially flat stubble treatmen...
