Beschreibung
Zusammenfassung:	The invention relates to the field of soil moisture content control, in particular to a system capable of carrying out a multilayer soil moisture content two-way control inside soil in an experimental field, and belongs to the field of agriculture meteorology. The control system for the soil moisture content in the experimental field comprises a soil moisture content controller, an air compressor, a frequency conversion water pump, a three-way electrovalve, an air-water pipeline, power transmission lines, signal control lines, a buried air-water spraying device, a pressure sensor and soil moisture monitors. The air compressor and the frequency conversion water pump are connected with the buried air-water spraying device through the three-way valve and the air-water pipeline. The system is applicable to being used in the experimental field.
