Method and system for saving water for photovoltaic intelligent nanometer micro moisturizing irrigation

Abstract

The invention discloses a method and a system for saving water for photovoltaic intelligent nanometer micro moisturizing irrigation. The system comprises a photovoltaic water pump, a micro moisturizing pipe, a water delivery pipe, a water potential instrument, a water supply main pipe, a water tank and a fertilizer tank, wherein a net structure is formed by connecting the micro moisturizing pipe with the water delivery pipe through a direct connecting way or a plug-in way, an irrigation net is formed, the water delivery pipe at one end of the irrigation net is connected with the photovoltaic water pump through the water supply main pipe, the photovoltaic water pump is connected with the water tank, the irrigation net is internally provided with the fertilizer tank and the water potential instrument, and the water potential instrument is connected with the photovoltaic water pump. The method and the system for saving the water for the photovoltaic intelligent nanometer micro moisturizing irrigation, disclosed by the invention, have the beneficial effects that uninterrupted and continuous irrigation can be realized, and characteristics of low energy consumption, high water conservation, blocking preventing and integrated water and fertilizer are obtained aiming to situations such as solute potential, soil water potential, atmosphere water potential, root water potential and pressure potential.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a water-saving method and system for photovoltaic intelligent nano-moisture irrigation. Background technique [0002] my country is the earliest country engaged in agriculture and water conservancy construction in the world. As a large agricultural country, my country has a large population, less cultivated land, shortage of water resources, frequent floods and droughts, special climate, geography and other natural and social conditions. Take the development path of irrigated agriculture. At present, the irrigation methods are mainly flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation and infiltration irrigation. Since most cities in our country are in a situation of severe water shortage, and in some droughts and little rain, lack of electricity Where the conditions are low, it poses a more serious challenge to the traditional irrigation metho...

[0002] my country is the earliest country engaged in agriculture and water conservancy construction in the world. As a large agricultural country, my country has a large population, less cultivated land, shortage of water resources, frequent floods and droughts, special climate, geography and other natural and social conditions. Take the development path of irrigated agriculture. At present, the irrigation methods are mainly flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation and infiltration irrigation. Since most cities in our country are in a situation of severe water shortage, and in some droughts and little rain, lack of electricity Where the conditions are low, it poses a more serious challenge to the traditional irrigation method. The traditional irrigation method is difficult to control the water content of the soil, the water use rate is not high, and it cannot continue to irrigate.
