摘要
本文基于2014—2020年西藏自治区拉萨市7年冬小麦生育期内降水和土壤水分数据,利用作物-土壤水量平衡公式的方法,研究了拉萨市不同降水年型冬小麦在相同灌水量的条件下年冬小麦降水量及需水量特征,计算出不同年型冬小麦灌溉需水量。
Based on the data of rainfall and soil moisture during the 7-year winter wheat growing period in Lhasa of Tibet Autonomous Region from2014 to 2020,the method of crop-soil water balance formula was used,and the characteristics of annual precipitation and water requirement of winter wheat in different precipitation years in Lhasa were studied under the same irrigation amount. Then,irrigation water requirement of winter wheat in different precipitation years was calculated.
