Abstract

The invention discloses a tea garden water and fertilizer precision irrigation system and a control method thereof, and relates to an irrigation system and a method thereof. A lower computer of the system comprises a lower computer wireless receiving and sending module, a high-speed camera, a soil water content sensor node, a water pump, a fertilizer pump and the like; an upper computer comprisesa single chip microcomputer module and an upper computer wireless receiving and sending module, and the upper computer wireless receiving and sending module and the lower computer wireless receiving and sending module are connected in two directions through wireless communication. The method comprises the following steps of: acquiring tea image data of a tea garden by utilizing the high-speed camera carried by an unmanned aerial vehicle, acquiring soil water content data of the tea garden in real time through the soil water content sensor nodes arranged between the tea gardens, transmitting the data to the upper computer for nutrient and water analysis, and carrying out precision fertilization and precision irrigation according to the analysis result. The tea garden water and fertilizer precise amount irrigation system can achieve the precision irrigation of water and fertilizer in the tea garden, can ensure the stable yield and quality of tea leaves, has the characteristics of fine and reliable management of the tea garden, low cost, simple operation, strong expansibility and the like, and has wide market prospect.

Description

technical field [0001] The invention relates to an irrigation system and a control method thereof, in particular to a tea garden water and fertilizer precision irrigation system and a control method thereof. Background technique [0002] Tea trees are foliage crops and have a high demand for water. Studies have shown that under certain cultivation conditions, factors such as the yield of tea and the precipitation in the two months before picking, the average temperature in the previous month, and the soil humidity in the growth period, etc. closely related. With more rain and humidity, the yield and quality of tea are excellent. Unsuitable growth conditions make tea easy to age, high in polyphenols, crude fiber, and astringent, reducing the yield and quality of tea. Appropriate soil moisture can not only improve the ability of tea tree roots to absorb and utilize nutrients, but also improve the utilization rate of soil nutrients. However, excessive water can also cause we...
