| 摘 要： | 由于各种客观因素的限制,一直以来人们往往习惯于讨论和研究不同节水灌溉工程技术形式间的灌溉节水量的差异,而对同一种灌溉技术在不同农户之间差异几乎没有涉及.利用在河北平原井灌区三河市大曹庄村安装的农用机井IC卡智能灌溉控制计量系统,对全村20余眼机井320户农户冬小麦春灌用水量的记录数据进行整理统计,发现农户之间灌水定额差异非常大,但是这种用水量的差异符合随机变量正态分布规律.根据这些数据,给出了相应的数学模型的表达形式.

| Abstract: | Because of the limit of various objective factors,people usually studies and discuss the irrigation water quantity difference between various water-saving irrigation technologies,while do not consider the irrigation water quantity differences between individual farmers.Using the IC card intelligence irrigation controlling & measuring system for motor-pumped well in Dacaozhuang Village,Sanhe City,located in the well-irrigating area of Hebei Plain,this paper counted the data of spring irrigation water quantity for winter wheat of 320 farmers and 20 wells.The result showed that the irrigation water quantity differences between farmers were quite obvious and the differences presented normal distribution.Based on the date,the corresponding mathematics model was put forward in this paper. |
