A precision sowing machine and precision sowing method for deep fertilization of corn positive holes

Abstract

The invention relates to a fine operation agricultural device and especially relates to a corn eutopic hole deep fertilizing fine seeding machine. The corn eutopic hole deep fertilizing fine seeding machine comprises a plurality of corn hole fertilizing hole-sowing monomers (36), land wheels (29), a tri-point suspension (34) and a frame, wherein the corn hole fertilizing hole-sowing monomers (36) are arranged on a cross beam (37) of the frame; each corn hole fertilizing hole-sowing monomer (36) further comprises a hole fertilizing monomer and a single chip-based control system; the hole fertilizing monomer comprises a front fixing plate (41), a fertilizing opener (1), a fertilizing soil-covering mechanism (2), a soil breaking wheel (3), an external sheave fertilizer discharger (11), a fertilizer box (12) and an intermittent fertilizer draining mechanism (16); and the single chip-based control system comprises a rotary encoder (31), a laser sensor (7) and a single chip (50). The corn eutopic hole deep fertilizing fine seeding machine provided by the invention is free from thinning and topdressing, is time-saving and labor-saving, is seed-saving and fertilizer-saving, is simple, convenient and practical, is capable of greatly simplifying the farm operation and is capable of reducing production cost.

Description

technical field [0001] The invention relates to a precision operation agricultural equipment, in particular to a precision sowing machine for deep fertilization of corn positive holes and a precision sowing method thereof. Background technique [0002] In the traditional corn planting agronomy, the base fertilizer should be applied before sowing, about 20cm from the ground surface; the mouth fertilizer should be applied when sowing, and the mouth fertilizer should be applied 3 to 5cm below the seeds. There are three peaks of fertilizer absorption in the corn planting process: the jointing stage, the big bell mouth stage and the tasseling and silking stage. These three stages should be topdressed in stages and deep topdressed. Practice has shown that the topdressing depth of 8-10cm increases yield by 10%-15% compared with 2cm depth, and the fertilizer utilization rate increases by about 15%. In this process, it is necessary to use different agricultural machinery and impleme...

AI Technical Summary

Problems solved by technology

In this process, it is necessary to use different agricultural machinery and implements multiple times to ditch the soil, which is not conducive to improving the operation efficiency, and the water loss in the soil is large.

Because the fertilizer in the middle of the corn root system cannot be absorbed in the strip fertilization, it leads to excessive fertilization, which has an impact on the environment
