Abstract

The invention discloses a system and a method for automatic spray irrigation based on water migration, belonging to the field of agricultural water-saving irrigation and automatic control. A traditional irrigation mode has simple control manner, is liable to cause deep leakage, brings negative effects on the growth of a plant, and causes the waste of water resources. According to the invention, variation of the diameter of a plant stem is used as a monitoring index of the water status of the plant, and opening and closing of a water pump and an electromagnetic valve are controlled; meanwhile, closing of the water pump is controlled according to the change status of soil humidity at the position of Z1, so spray irrigation for different areas is realized. The system and the method provided by the invention have the following advantages: automatic and accurate irrigation for the plant can be realized; the requirement of the plant for water is met; deep leakage is unlikely to occur; and the utilization efficiency of water is improved.

Description

technical field [0001] The invention relates to the field of agricultural water-saving irrigation and automatic control, in particular to an automatic sprinkler irrigation system and method based on water migration. Background technique [0002] The growth of plants is inseparable from the absorption of water, and plants absorb water through the root system, so the water below the root system is invalid water. At present, most practiced irrigation methods in actual production are flood irrigation, which depends on the actual experience of the operators and has no theoretical support. The timing of irrigation opening and closing is still manually explored, and sometimes there will be a lag, resulting in untimely irrigation and loss of crops; deep seepage will occur, resulting in unnecessary waste of water resources. In order to save water and alleviate the problem of water shortage, sprinkler irrigation technology has been vigorously promoted in the field of irrigation. [...
