The Development ofAutonomously Controlling System for Water-Efficient Infiltrating Irrigation in Sandy Land |
| |
| Abstract: | An autonomously controlling system fo r water efficient infiltrating irrigation is introduced. The constitution and a ssembling proceeding of the system as well as its supporting software and hardwa re, and the function indicators are detailed in the paper. The system is coming with easy design, low cost and high reliability. It can autonomously monitor the upper limit and the lower limit of soil moisture in sandy land and water tabl e in percolating pot. Based on the needed information the system will supply w ater autonomously, which can reduce labor intensity considerably. The autonomous ly controlling system is favorable for the modernization management of agricultu re by appling computer technology, which is worthy of popularization in water e fficient agriculture. |
