| 摘 要： | 根据１９９３－１９９５年的试验资料及应用有关的气象资料，提出了降水量及土壤不不分的干旱指标，采用农田水量平衡方法建立了农田土壤水分动态预报模型，通过检验，对０－１００ｃｍ深土壤水分邓相对误差为±５．７％，提出了干旱预报方法，在以 上工作的基础上，建立了一个针对内蒙古旱农试区马铃的干旱监测系统。

| Abstract: | According to the data of field experiment (1993~1995) in the Wuchuan Inner Mongolia Drought Agriculture Experiment Area and the relevant meteorological material,potato water stress indexes of precipitation and soil water were bring up. A model of the prediction equation of soil moisture was built by means of the field water balance. The rel-ative errors of the predictions from this model are about 15. 7% in the depth of lOO cm of soil. Means of prediction are put forward. Base on all of the work a potato drought-moni-toring system for the area in the north of Yin Mountain of Inner Mongolia was set up. |
