Problems solved by technology

[0006] The Venturi dosing (fertilization) device uses the vacuum generated by the increase of the flow velocity in the throat to uniformly suck the fertilizer solution into the irrigation pipe and mix it with water. The existing problems are high operating pressure requirements, large water head loss, and serious suction phenomenon. limited range
The main disadvantage of the differential pressure fertilization tank is that the concentration of the chemical agent decays with time, and it is difficult to control the dosing time

Abstract

The invention relates to a fertilizing device, in particular to a proportion decreasing fertilizer device: a fertilizer solution is loaded into a deformable fertilizer bag, and the fertilizer bag is placed in a closed pressure tank, the pressure tank is connected to a water main and a fertilizer bag outlet is connected to a water pipe. An adjustable pressure reducing valve is arranged at the middle of two connectors of the water main to form a certain pressure difference between the two ends, when the tank body is full of water, the pressure in the closed pressure tank is greater than the pressure of a pipe at an outlet of the fertilizer solution, and the fertilizer solution can be dripped into the water pipe. The proportion decreasing fertilizer device also discloses an application methodthereof. The proportion decreasing fertilizer device has the advantages of simple structure, uniform fertilization, low-energy consumption and controllable proportionality.

Description

technical field [0001] The invention relates to a fertilization device, in particular to a tapered proportional fertilizer, which is a new type of equipment for adding liquid fertilizer to a spray (drip) irrigation system and used in a water-fertilizer integration project. Background technique [0002] With the country's increasing emphasis on agriculture, agricultural facilities have been effectively promoted. The irrigated area of ​​farmland in my country is increasing day by day, and the consumption of fertilizers and pesticides is also increasing. The fertilization device is an indispensable and basic part of the water-saving irrigation system, and its performance directly affects the quality of irrigation and fertilization and crop yield. [0003] There are two traditional methods of adding fertilizers. One is to use electric pumps to add fertilizers on the garden main pipe, and the other is to use the water pressure difference of the drip irrigation system to inject. ...
