Study on the Moisture Sensor Laying Place in Watching and Forecasting Soil Moisture Content
Yan Shi · 2006
It can provide basis for calculating and forecasting of soil moisture content(drought) by laying the moisture sensors in different depths under the earth and watching the changes at all times.And the laying place of the moisture sensor is the key matter.The author has installed 8 moisture sensors in Lucheng Irrigation and Hydroelectric Center Base in Daxing Town of Beijng from 11th November in 2003,and calculated the moisture rates in soil body at 10、20、30、40、50、60、80、100cm under the earth every four hours per day. In this paper,the moisture sensor laying place at 10、30、60、100cm under the earth is suggested through the related analysis of the data of soil moisture content.
