| 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 whieh were monitored with oven drying method, the corre-lation of soil water content in different depths and different positions was analyzed, the data of 8 depths at different posi-tions 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, 20~30cm, 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. |
