Layered fertilizer applicator for wheat

Abstract

The invention discloses a layered fertilizer applicator for wheat. The layered fertilizer applicator comprises a machine frame (1), wherein a driving device (2) is mounted on the machine frame (1), apower output shaft end of the driving device (2) drives a driving wheel (3) and a reduction gearbox (4) in a belt transmission mode, and the power output shaft end of a reduction gearbox (4) drives alayered fertilizer applicator in a belt transmission mode; and the layered fertilizer applicator comprises a fertilization box (5), wherein a material distribution box (6) communicating with the interior of the fertilization box (5) is mounted at the bottom of the fertilization box (5), the whole material distribution box (6) is of a hollow cylindrical cavity structure, and a material distributioncolumn (7) concentric with the material distribution box (6) is arranged in the material distribution box (6). According to the invention, the burying depth of a furrowing coulter can be automatically adjusted effectively according to the layering condition of a root system of the wheat in each stage process, the overall fertilizer discharging effect is smooth, and the situation of missing application is avoided.

Description

technical field [0001] The invention relates to the technical field related to agricultural equipment, in particular to a wheat layered fertilizer applicator. Background technique [0002] Topdressing wheat with urea is very helpful to the growth of wheat, but if you do not pay attention to the application method when topdressing wheat with urea, you will not get good results. It is well known that urea has high nitrogen content and is widely used in wheat planting In addition to being used as base fertilizer for crops, urea is mostly used as topdressing fertilizer for wheat. The practice of deep application of soil covering has proved that after 4 to 5 days of applying urea to the ground surface at room temperature, most of the nitrogen will be ammoniated and volatilized. Its utilization rate is only about 30%, especially on the surface of calcareous and alkaline soil, the volatilization loss of ammonia is more serious. Therefore, when using urea to topdress crops in dry f...
