Study on the placement of sensors for moisture content in soil profile for cotton under mulched drip irrigation condition
摘要
Abstract
In order to find the layout scheme of moisture probes in soil profile for drip irrigation under mulch, a field experiment was conducted in the oasis region of Xinjiang during 2009. Based on the observation data of moisture content in different depths and different positions in soil profile which were monitored with oven drying method, the correlation of soil water content in different depths and different positions was analyzed, the data of 8 depths at different positions were sorted by R type hierarchical clustering method, and the layout scheme of soil moisture probes was screened out in cotton filed with drip irrigation under mulch. The experimental verification results showed that it was reasonable that soil moisture probes were embed into 0 ~ 10 cm, 20 ~ 30 cm, 40 ~ 50 cm and 60 ~ 80 cm in vertical direction and 0 cm, 32.5 cm and 50 cm distance with drip line in horizontal direction.关键词
