Abstract

The invention belongs to the field of field irrigation and fertilizer distribution and discloses a mobile multifunctional constant-pressure irrigation fertilizer distributor and an irrigation and fertilizer distribution method thereof. The irrigation fertilizer distributor comprises a main pipeline, a water pump and a fertilizer applicator. The main pipeline is used for conveying water-fertilizer fixed liquid. The water pump is used for extracting irrigation water of the main pipeline and adjusting water inflow of the irrigation water. The water pump is controlled by a variable frequency constant-pressure control device to pressurize the irrigation water. The fertilizer applicator is used for conveying fertilizer and nutrient solution to the main pipeline. The variable frequency constant-pressure control device is connected with the main pipeline through a pressure sensor and used for receiving pressure signals acquired by the pressure sensor and controlling rotation speed of the water pump. By the irrigation fertilizer distributor and the irrigation and fertilizer distribution method thereof , irrigation pressure and flow can be controlled simultaneously, stable system fertilizer distribution concentration can be guaranteed while blocking and corrosion of the irrigation system can be prevented, the requirements for even and high-quality irrigation and fertilizer distribution can be satisfied, and energy conservation can be achieved.

Description

technical field [0001] The invention belongs to the field of farmland irrigation and fertilization, and in particular relates to a mobile multifunctional constant-pressure irrigation and fertilization machine and an irrigation and fertilization method thereof. Background technique [0002] In recent years, with the continuous warming of the global climate, the frequency, severity and duration of extreme weather and climate events have increased rapidly, seriously affecting the survival of human beings and the sustainable development of society. Strengthening the construction of water supply projects and changing the scattered and passive drought response methods are the main measures to prevent the impact of drought disasters on crops. [0003] Sprinkler irrigation and micro-irrigation technologies are important water-saving measures in the field irrigation process in my country. As of 2010, the sprinkler irrigation area in my country was 45.38 million mu, accounting for 11...
