农田土壤湿度测定农田土壤湿度测定measurement of soil moisture nongtian turang shidu eeding农田土壤湿度测定(measurement of 5011moisture)农田土壤水分贮存量及其变化的测定，是土壤农业水文特性测定的基础工作。其目的在于揭示农田土壤水分状态及其运动规律，掌握作物的水分供应状况，为编制作物水分供应情报和预报，鉴定农机具田间工作条件与效率，以及为采取农业技术措施提供定量依据。 自古以来，中国农民就有看墒种庄稼的经验，人们常以若干个等级来表示上壤干湿状况。许多国家测定土壤湿度仍多采用土钻取土，进行称重烘干的方法。20世纪50年代以来，中国气象站采用此方法。为了能够连续记录土壤湿度的变化，并减轻劳动强度，60年代以来，美、英、苏联、日本等国广泛使用中子法、了射线法、电阻法和负压计等方法进行测定。中国一些科研单位也引进使用这些方法。遥感测定土壤湿度技术正在发展，利用卫星红外扫描仪等先进设备测定区域或全球的土壤湿度已成为卫星探测的重要研究内容之一。 测定要求由于农田土壤物理特性和化学成分分布的不均一性，以及耕种的影响，造成土壤中水分含量的垂直梯度和水平分布的差异。因此，测定土壤湿度时要求分层和多点(多次重复)测定，求得农田不同层次的平均土壤湿度。为了掌握土壤湿度随时间的变化规律，还要进行周期测定。测定地段一般选在观测农作物生育状况的田块上，分l州定和非固定地段两种。前者选在地形、地势和上壤等条件有代表性的地段，周年进行测定。在上壤不冻结和冻结深度未超过10厘米时，呼旬末和作物各发育期浩遍期时测定。当七壤冻结深度超过10厘米以后.则停止测定。测定深度是地表下l()0厘米，每隔l()厘米取一上层(表层分为卜5、5一10厘米从每一士层取四个币复。非1司定地段随主要作物生育状况观测地段的转移而变动。观测日期、分层和玉复次数与固定地段做法相同，但测定深度改为50厘米) 测定方法分为三类: 直接测定法是把上壤中水分与固体部分相分离的方法〕属于这类的方法有:①称玉烘干法。用取上钻从田间取来上样，在1()()一1()5℃恒温条件下.烘烤到干燥状态，并用烘干前后的币量求出上样的含水鼠。烘烤土样多采用电热恒温干燥箱，它能控制适宜的烘烤温度，因此测定结果比较准确，使用较)’‘，但缺点是测定时间长。有的使用红外干燥箱，虽然缩短了烘上时间，但因温度较高，容易影响测定精度采用简易加热设备的，则因烘烤温度不易控制，精度较旅称玉烘干法是人工取土，劳动强度较大，又不能定点观测上壤湿度的连续变化;②酒精法。
