Wide wheat seeding ridge lower position uniform fertilizer apparatus

Abstract

The invention provides a wide wheat seeding ridge lower position uniform fertilizer apparatus, which can complete operations such as wide seeding ridge lower position fertilization, earth covering and seedbed leveling in one time. The wide wheat seeding ridge lower position uniform fertilizer apparatus comprises a ditching device and an earth covering device, wherein the ditching device comprises a supporting leg, a plough tip curved plate, a fertilizer stopping plate, a fertilizer distribution plate, lateral baffles, a rear baffle and an upper cover plate; the plough tip curved plate is located in front of the supporting leg; the fertilizer stopping plate is located below the supporting leg; the fertilizer distribution plate is arranged on the fertilizer stopping plate and located under a fertilizer discharge channel; the lateral baffles are located behind the plough tip curved plate and located on the left and the right sides of the supporting leg; the rear baffle is located behind the supporting leg; the upper cover plate is integrated with the plough tip curved plate, the lateral baffles and the rear baffle to form a cavity with a bottom opening and with the other sides enclosed; the lower part of the supporting leg extends inside the cavity; the earth covering device comprises an earth pressing plate connected with the ditching device, and earth scrapers on both sides of the earth pressing plate.

Description

Technical field [0001] The invention relates to a fertilization device, in particular to a uniform fertilization device under a wide wheat seedling belt, belonging to the field of agricultural machinery. Background technique [0002] The formation of wheat yield depends on the coordination of individuals and groups. The excellent colony structure facilitates ventilation and light transmission in the canopy of the wheat colony, makes the individual growth and development healthy, and promotes the increase of wheat yield. In the traditional wheat production, drill seeding is the main method. The seeding distance is uneven and the seeding amount is large, which is not conducive to the formation of high yield. Precise sowing of the wide seedling belt of wheat can make the seeds evenly distributed in the field, and each plant can obtain sufficient nutrient area and space, maximize water and fertilizer, effectively tiller, and increase the number of wheat ears, with large ears and suf...

AI Technical Summary

Problems solved by technology

[0004] At present, the three fertilization methods of ordinary drill fertilizer applicators (mixed seed fertilizer, side fertilization and bottom fertilization) cannot fully meet its requirements.

There is no report on the form of working parts that can complete the operations of uniform fertilization, soil covering, and seed bed leveling in a wide seedling belt at one time.
