A mobile drip irrigation water, fertilizer and gas all-in-one machine

Abstract

The invention relates to a mobile drip-irrigation integrated machine of water, fertilizer and gas. The machine is characterized by including a machine base and a water storage tank, a liquid fertilizer box, a fertilizer storage box, a micro-nano bubble generator, a first self-priming pump, a second self-priming pump, a control system and an electric generator which are arranged on the machine base; a water inlet of the water storage tank is connected with a water supply system, another water inlet of the water storage tank is connected with a water outlet of the micro-nano bubble generator, awater outlet of the water storage tank is connected with a water inlet of the micro-nano bubble generator, another water outlet of the water storage tank is connected with a water inlet of the first self-priming pump, a water outlet of the first self-priming pump is connected with a water inlet of the liquid fertilizer box, a liquid outlet of the fertilizer storage box is connected with an liquidinlet of the liquid fertilizer box, a liquid outlet of the liquid fertilizer box is connected with a liquid inlet of the second self-priming pump, and a liquid outlet of the second self-priming pump is connected with a drip irrigation system; the micro-nano bubble generator, the first self-priming pump, the second self-priming pump, a flowmeter, various sensors and various electromagnetic valves are electrically connected with the control system separately. The machine can be widely used in the technical field of agricultural novel water-saving irrigation.

Description

technical field [0001] The invention relates to a mobile drip irrigation water, fertilizer and gas integrated machine, which belongs to the technical field of new agricultural water-saving irrigation. Background technique [0002] A large number of studies have shown that while long-term drip irrigation provides water and nutrients for crops, it also excludes the air in the pores of the root zone, causing a temporary or long-term anaerobic environment in the root zone, which affects the healthy growth of crops. Therefore, the term "oxygenated irrigation" A new concept of water-saving irrigation technology was born in response to the situation. In the early years, researchers made a lot of attempts to add oxygen, such as: ① drip hydrogen peroxide to the root zone of crops, and use soil catalase to decompose to generate oxygen; ② use Venturi gas injector to form tiny air bubbles and The irrigation water is fully mixed and transported to the root zone of the crops; ③The air co...

AI Technical Summary

Problems solved by technology

[0004] Based on existing research, it is not difficult to find the following problems in the application of water, fertilizer and gas integration technology: ① Existing irrigation, fertilization, and aeration equipment are scattered and arranged at the head of the system, occupying a large area and not centralized ; ②Because the micro-nano bubble generator has a certain effective irrigation area, it is difficult to supply the oxygen supply demand of crops planted in a larger area. Irrigation efficiency, the cost of configuring one device for each control area is too high, which affects the promotion and practice of oxygenated irrigation equipment and methods
