With the development of the technology, micro-spray irrigation is currently available, which is also called fog drop sprinkling irrigation. In recent years, an advanced irrigation technology is newly developed and developed on the basis of summarizing sprinkling irrigation and drip irrigation at home and abroad. The micro-spraying technology is more water-saving than spray irrigation, and is more applicable than spray irrigation due to fine fog drops, so that the whole process from the seedling stage to the growth and harvest stage of crops is applicable. The irrigation device utilizes a low-pressure water pump and a pipeline system to deliver water, sprays the water into the air through a specially designed micro-atomizing nozzle under the action of low-pressure water, disperses the water into fine fog drops, and sprays the fine fog drops on the branches and leaves of crops or the ground under the crowns, namely micro-spraying for short. The micro-spraying can not only increase the soil moisture, but also improve the air humidity, and play a role in regulating microclimate.

But above-mentioned two kinds of irrigation methods all are artifical and detect and open irrigation equipment, and the scope of irrigating is very wide, the area is very big, also can make some crops that do not need the irrigation like this carry out repeated irrigation, and the utilization ratio of water source is lower relatively. Therefore, at present, there is an urgent need for a device and method capable of automatically detecting water shortage of crops and realizing accurate irrigation.
