Abstract

The invention relates to a urea-ammonium nitrate solution water and fertilizer integrated application device and a fertilization method, wherein the application device comprises a traction device, anagent box frame with wheels, an agent box arranged on the medicine box frame, and a fertilization device frame hinged to the agent box frame. The fertilization device frame is fixedly connected to a suspension device connected to a traction device. A fixed joint point of the suspension device and the fertilization device frame is eccentric with a horizontal shaft. The fertilization device frame isprovided with a trenching device. The agent box is communicated with a fertilization pipe extending to the trenching device. Through application of UAN solution fertilizer based on the device, the UAN solution fertilizer can be directly absorbed by the crops so that the absorption speed is increased, nutrients can directly reach the root system and the fertilizer efficiency is greatly improved. Through collection and treatment on a driving rate in fertilization, the fertilization flow is adjusted so that the amount of fertilizer per unit area is consistent, precise fertilization is achieved and uneven fertilization caused by different driving rates is avoided.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to equipment for applying water and fertilizer integrated with urea ammonium nitrate solution and a fertilization method. Background technique [0002] Urea ammonium nitrate solution (UAN), also known as nitrogen solution, is a new type of high-efficiency and environmentally friendly fertilizer. It concentrates three nitrogen sources into one product, which can take advantage of various nitrogen sources. Nitrate nitrogen can provide an immediate source of nitrogen for rapid uptake by crops. A part of the ammonium nitrogen is absorbed immediately, and a part is absorbed by the soil colloid, thus prolonging the fertilizer effect. Urea hydrolysis takes time, especially at low temperatures and usually acts as a long-lasting nitrogen fertilizer. UAN is the basic raw material for the production of liquid compound fertilizers and water-soluble fertilizers. It can also be applied di...
