Abstract Along with the popularization and application of the development of information technology and computer, the application of information technology in agricultural production in the future will be the important direction of agricultural development. In this paper, study on cotton field management in Xinjiang by remote sensing technique with the non-destructive testing technology and wireless sensor technology. The results show that remote sensing has very good correlation in cotton yield assessment, crop growth, using the NDVI time series similarity estimation of cotton with high analysis accuracy, R2=0.82, which is simple, suitable for application. SPAD meter was correlated with the nitrogen content in cotton leaves, flowering period of cotton leaf chlorophyll relative content of SPAD R2=0.6135. Soil moisture wireless sensor network can change the soil moisture good monitoring; provide the basis for decision-making of irrigation. Keywords: Cotton Yield Estimation; Soil Moisture Monitoring; Nutrition Diagnosing; Field Management

究利用无损检测技术、无线传感技术结合遥感技术对新疆生产建设兵团农八师一四八团棉花生产管理进行应用示范。结 果表明遥感在棉花产量评估、作物长势都有很好的相关性,利用 NDVI 时间序列相似性分析方法估算棉花单产具有较高 的精度,R2=0.82,方法简单,适合推广应用。SPAD 与棉花叶片氮素含量有一定的相关性,盛花期间 SPAD 计测定棉花 叶片叶绿素相对含量 R2=0.6135;土壤水分无线传感网络可以很好的监测土壤水分的变化,为灌溉决策提供依据。 关键词:棉花估产;土壤水分监测;氮素诊断;田间管理

引言 新疆是我国重要的农业生产基地,是我国棉花等农作物的主要产区之一[1, 2]。随着整个棉花生产规模的不 断扩大,资源条件有限,市场竞争日益激烈,利用信息技术提升和促进新疆棉花生产与发展已经成为当前新 疆现代农业技术研究的主要任务之一。这也符合《国家中长期科学与技术发展规划纲要》的基本思路,其中 明确提出加快农业信息技术集成应用,提高我国整个农业行业的生产效率。 利用遥感、视频和传感器等手段快速、便捷地获取大面积棉田土壤、作物的信息,采用 GIS 技术和农业 专家系统技术对采集到的多源信息进行融合分析和专家推理[3-7],提高棉花生产过程的决策管理水平,实现由 传统农业到定量、规范、和智能化农业的转化,由粗放到精细,由经验判断到科学决策 [8-10],将农业信息技 *基金项目:863
