Problems solved by technology
[0008] One of the purposes of the present invention is to provide a liquid fertilizer rhizosphere topdressing profiling monomer to solve the problem that the current foliar spraying liquid fertilizer equipment is difficult to accurately add liquid fertilizer to the rhizosphere of crops, and to solve the problem of drip irrigation and fertilization technology on crops. When adding liquid fertilizer directly to the rhizosphere, it is easy to cause damage to the root system of the crop
[0009] The second object of the present invention is to provide a topdressing system based on the above-mentioned liquid fertilizer rhizosphere topdressing profiling monomer, in order to solve the problem that the current deep-applying liquid fertilizer farm tools have extra power consumption when topdressing, and the flow rate of liquid fertilizer There is a problem with a large error in the adjustment

The invention relates to the technical field of agricultural machinery, and provides a liquid fertilizer rhizosphere topdressing profiling monomer and a topdressing system. The liquid fertilizer rhizosphere topdressing profiling monomer includes an articulated bracket, a pressing profiling device, a profiling wheel, and a ground shovel and fertilization pipe; also includes an obstacle avoidance swing mechanism; the obstacle avoidance swing mechanism is located on the left and / or right side of the pressing profiling device; one end of the obstacle avoiding swing mechanism is connected with the pressing profiling device, and the other end is connected with the fertilization pipe, The fertilization port of the tube extends laterally towards the rhizosphere of the crops to be fertilized; the obstacle avoidance swing mechanism is used to passively adjust the fertilization tube to swing back and forth to avoid the crops to be fertilized; The liquid fertilizer is applied, and the outlet flow and pressure of the liquid fertilizer at the fertilization port of the fertilization pipe are kept constant, which greatly reduces the volatilization of the liquid fertilizer and ensures that the crops can fully absorb the liquid fertilizer.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a liquid fertilizer rhizosphere topdressing profiling monomer and a topdressing system. Background technique [0002] Liquid fertilizer is a liquid product containing one or more nutrients needed by crops. Compared with solid fertilizers, liquid fertilizers can be adaptively proportioned according to the needs of different crops for nutrient elements, and liquid fertilizers have the advantages of high utilization rate, good fertilization effect, less environmental pollution, and easy operation. [0003] At present, at home and abroad, the fertilization machines for liquid fertilizers can be divided into three categories: foliar spraying, drip irrigation and fertilization, and deep application of liquid fertilizers. [0004] Foliar spraying liquid fertilizer equipment is mainly to spray liquid fertilizer on the leaf surface of crops. The operation efficiency is hig...
