智慧苹果园“空-天-地”一体化监控系统设计与研究 总被引:1,自引:0,他引:1
针对传统苹果园存在的数据监测体系不完善、管理缺乏科学数据等问题,开发了一种苹果园“空-天-地”一体化监控系统。综合应用卫星遥感、无人机、农业物联网、人工智能等现代信息与智能装备技术,集成果园信息采集装置套件,并基于SSM框架(SpringMVC、Spring、Mybatis)构建果园监测集成数据中台。通过果园“空-天-地”一体化的信息技术采集体系集成创新和基于AI的苹果病虫害图像识别应用,实现覆盖果园土壤、生态环境、果树个体及群体的立体化监测服务功能,提高果园监测效率与数据可信度,对促进苹果园生产管理向着科学化、数字化、智能化转变的新业态升级具有重要研究意义。 相似文献

玉米在不同水分条件下开花相关性状的QTL分析 总被引:1,自引:0,他引:1
Drought is one of the most important factors influencing maize yield.QTL analysis for related traits under water stress will facilitate the understanding of genetic mechanisms of drought tolerance and provide the basis of marker-assisted selection.The present study conducted QTL analysis of flowering-related traits including days to tasseling,days to silking,days to anthesis and anthesis to silking interval(ASI) under different water regimes in Xinjiang and Beijing,using 139 F2∶3 families of A188×91 Huang 15.Totally 26 QTL were found to be associated with the flowering-related traits under normal water conditions,with the range of LOD of 2.62-8.40 and the range of phenotypic variance explained of 9.1%-43.2%.A QTL located near the marker"bnlg1176" on chromosome 8 controlled days to tasseling,days to silking and days to anthesis.Meanwhile,six QTL were found to be associated with the flowering-related traits under drought stress,with the range of LOD of 2.6-5.6 and the range of phenotypic variance explained of 9.5%-58.0%.A QTL also located near the marker "bnlg1176" on chromosome 8 controlled days to tasseling and days to silking,which could explain 16.6% and 20.5% of phenotypic variance.The genomic region near bnlg1176 on chromosome 8 is presumed to be an important region because eight QTL were found. 相似文献
