摘要
小麦渍害是指土壤水分达到饱和,造成空气不足、土壤通透性差、排水不畅,土壤表层水位过高而对小麦正常生长发育所产生的危害,对小麦产量与品质易造成较大影响。本文从水分胁迫、气体胁迫和离子胁迫三个方面分析了渍害产生的原因;从根系、叶片、产量和营养品质四个方面阐述了渍害对小麦生长的影响;从图像处理技术、作物模型和遥感技术三个方面归纳了渍害的监测方法;从多方面提供了渍害的防御建议;并对未来小麦渍害的研究进行了展望,以期为小麦渍害预警、减灾防御和减产评估提供参考。
Wheat waterlogging refers to the saturation of soil moisture,resulting in insufficient air,poor soil permeability,poor drainage,high surface water level and the damage to the normal growth and development of wheat,which has a great impact on wheat yield and quality.In this paper,the causes of waterlogging were analyzed from three aspects:water stress,gas stress and ionic stress.The effects of waterlogging on wheat growth were described from four aspects:root,leaf,yield and nutrient quality.Image processing techniques and crop models were used.The monitoring methods of waterlogging were summarized in three aspects of remote sensing technology.The suggestions for waterlogging prevention were provided from various aspects,and the future research on wheat waterlogging was prospected.In order to provide reference for wheat waterlogging warning,disaster reduction defense and production reduction assessment.
