摘要
根据新疆试验区滴灌棉田不同位置、不同深处全生育期的地温数据,通过相关性分析发现,滴灌棉田同一观测点不同深处的地温具有较强的相关性;用R型谱系聚类法,对各观测点8个层次的地温变量进行分类,分为4类时,在地表0cm以及地表下5、15和40cm深处的地温就能较好的反映0～80cm土层的平均地温。水平方向上膜下宽行的平均地温最能反映滴灌棉田剖面上的土壤地温;膜下宽行处地表0cm以及地表下5、15和40cm深处可作为1膜2带4行滴灌棉田地温探头的最优布设点。
A field experiment was conducted in the oasis region of Xinjiang Province during 2010, the data of soil temperature in different depths and different position in soil profile with geothermometer. The cor- relation of soil temperature in different depths and different position was analyzed, and 8 depths data of different position were sorted by R type hierarchical clustering method. The results showed that it was reasonable that soil temperature sensors were embed mulching film for monitoring the soil temperature in into 0, 5, 15 and 40 cm at the central positions below cotton filed of drip irrigation.
