Base fertilizer layered application device and method

Abstract

The invention provides a base fertilizer layered application device and method. According to the device, a plurality of fertilizer discharging pipes of different lengths are arranged in each of layered fertilizing mechanisms; the layered fertilizing mechanisms are arranged between rotary blades and a soil-flattening dragging plate; the rotary blades are located in a soil-baffling cover; and the plurality of layered fertilizing mechanisms are arranged parallel to each other on a frame. The rotary blades mill soil and throws out soil clods, the soil clods are impacted by the soil-baffling coverand the soil-flattening dragging plate, fertilizers are applied to fertilization plough layers of different lengths by the fertilizers discharging pipes of different lengths and are covered by the falling soil clods, and then the soil clods are scrapped to be level by the soil-flattening dragging plate. Through combined usage of the fertilizer discharging pipes of different lengths in the layeredfertilization mechanism and a rotary tillage mechanism, the base fertilizer layered application device and method can realize layered application effect of fertilizers without a deep ditch shovel anda furrow opener, the layered fertilization precision is high, and the base fertilizer layered application device is simple in structure, economic and practicable.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a device and method for layered application of base fertilizer. Background technique [0002] Base fertilizer application is an important part of crop cultivation. The traditional method of artificial basal fertilizer application is mainly to manually spread the basal fertilizer to the surface, and then use a rotary tiller to mix the fertilizer with the surface soil, or use a conventional plow to bury the surface fertilizer deep into the bottom of the plow. In order to reduce the labor intensity of manual fertilizer application and improve the operational efficiency of basal fertilizer application, some researchers have studied basal fertilizer application equipment that works with rotary tillers. The main working principle of traditional rotary tillage basal fertilizer application equipment is that a fertilizer box is installed on the upper end of the rotary tiller, and th...
