根据2009年度西北农林科技大学旱区农业水土工程重点实验室的温室枣树试验资料，使用 Penman-M onteith公式计算出枣树生育期内参考作物蒸发蒸腾量，求得充分供水条件下温室枣树全生育期作物需水量为394．9 mm，计算出了关中地区温室枣树全生育期的作物系数为0．90，各生育期的作物系数分别为萌芽展叶期0．63，开花坐果期0．95，果实膨大期1．01，果实成熟期0．87。建立了作物系数与萌芽后天数的二次曲线函数关系。以期为建立关中地区枣树的高效节水灌溉模式提供理论基础。
根據2009年度西北農林科技大學旱區農業水土工程重點實驗室的溫室棘樹試驗資料，使用 Penman-M onteith公式計算齣棘樹生育期內參攷作物蒸髮蒸騰量，求得充分供水條件下溫室棘樹全生育期作物需水量為394．9 mm，計算齣瞭關中地區溫室棘樹全生育期的作物繫數為0．90，各生育期的作物繫數分彆為萌芽展葉期0．63，開花坐果期0．95，果實膨大期1．01，果實成熟期0．87。建立瞭作物繫數與萌芽後天數的二次麯線函數關繫。以期為建立關中地區棘樹的高效節水灌溉模式提供理論基礎。

Based on the greenhouse jujube's test data from Northwest A&F University's key laboratory of Arid Area Agricultural Wa‐ter and Soil Engineering in 2009 ,this study has calculated the reference crop's evapotranspiration in jujube's growth period by Penman-Monteith formula .Specifically ,crop's water requirement of greenhouse jujube in the whole growth period is 394 .9 mm under ade‐quate water supply ,crop coefficient is 0 .90 of greenhouse jujube in the whole growth period ,crop coefficients in each growth stage are as follows 0 .63 of germination frondesce stage ,0 .95 of blossom and fruit stage ,1 .01 of fruit enlargement stage ,0 .87 of fruit mature stage .According to these data ,the study has established the quadratic function between crop's coefficient and the number of days after germination to provide a theoretical basis for the establishment of jujube's efficient water-saving irrigation method in Guanzhong area .
