Layered deep fertilizing and seeding device and layered deep fertilizing and seeding method

Abstract

The invention discloses a layered deep fertilizing and seeding device and a layered deep fertilizing and seeding method. The device comprises a furrowing blade, a slow-release fertilizer tube, a first disc opener, a quick-acting fertilizer tube, a second disc opener, a covering device, a press wheel, a seed box, a four-bar copying mechanism, a quick-acting fertilizer box, a slow-release fertilizer box and a rack, wherein the quick-acting fertilizer box and the slow-release fertilizer box are arranged on the rack in parallel; the slow-release fertilizer tube and the slow-release fertilizer box are connected and arranged behind the furrowing blade; the quick-acting fertilizer tube and the quick-acting fertilizer box are connected and arranged behind the first disc opener; the rack is connected with a seeding monomer through the four-bar copying mechanism. According to the layered deep fertilizing and seeding device and the layered deep fertilizing and seeding method, the seed and fertilizer casting depth consistency can be improved, accurate layered fertilization is achieved and the fertilizer utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a layered deep fertilization and seeding device and method. Background technique [0002] At present, in the process of layered deep application of base fertilizer, most of the existing technologies and equipment adopt the method of opening fertilizer outlets at different heights on a fertilizing shovel. The accuracy of layered fertilization is low, and the layered effect cannot be guaranteed. Moreover, a kind of fertilizer is applied in layers, and the fertilizer is covered around the seeds. In essence, it is still used as a seed fertilizer and cannot replace top dressing for later absorption by crops. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, provide a layered deep fertilization seeding device and method, improve the consistency of seed and fertilizer application depth, realize precise lay...
