Crop irrigation system and irrigation method thereof

Abstract

The invention relates to the technical field of agricultural irrigation equipment and discloses a crop irrigation system and an irrigation method thereof. The crop irrigation system comprises a solar power supply assembly capable of converting solar energy into electric energy, a main control box arranged on the solar power supply assembly, a growth vigor monitoring assembly arranged on the solar power supply assembly and capable of monitoring crop growth vigor in real time, a soil parameter monitoring unit capable of being wirelessly connected with the main control box and a water supply and fertilization assembly, wherein the growth vigor monitoring assembly can perform wire transmission of monitored real-time growth vigor information of crops to the main control box. The main control box is respectively electrically connected with a water supply solenoid valve and a fertilization solenoid valve in the water supply and fertilization assembly and can control the water supply solenoid valve and the fertilization solenoid valve to be switched on or off according to actual water content and conductivity of crops monitored by the soil parameter monitoring unit. The irrigation system can determine water demand and fertilizer demand according to crop growth vigor to perform irrigation and have the advantages of saving water resources and improving fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation equipment, in particular to a crop irrigation system and an irrigation method thereof. Background technique [0002] Xinjiang is located in the hinterland of the Eurasian continent and has a typical continental arid climate. The average annual precipitation is only about 200 millimeters, while the evaporation reaches more than 2,000 millimeters. Xinjiang is an irrigated oasis for agriculture, and agricultural water accounts for 95% of the total water consumption. Above, therefore, the water crisis has a great impact on Xinjiang's agricultural development. [0003] The water for drip irrigation in Xinjiang mainly depends on human experience judgment and artificial forced sequential drip irrigation, which is a serious waste of water. Most of the existing automated irrigation systems are controlled only based on the corresponding threshold of soil moisture content, which is not targe...
