探讨并建立了适合于中国华北地区夏玉米水分状况监测的作物水分胁迫指数(CWSI)模型。
The crop water stress index (CWSI) model for monitoring summer maize water stress in North China Plain (NCP) was set up in this paper.
这些表明CWSI较好的反映了因土壤供水不足导致的作物水分胁迫，CWSI与叶水势之间呈明显的负相关关系。
The above inclusions show that the plant water stress is due to the lack of water, Thereis obvious negative correlation between CWSI and leaf water potential.
通过对作物水分胁迫系数和氮素胁迫系数的模拟计算，可以求出最佳的灌水、施肥时间和各个时间段分别的灌水、施肥用量。
Through the calculation of the water stress index and N stress index, when and how much irrigation and fertilization can been decided.
综述了作物的耐旱机制、水分胁迫下的生理生化反应及超微结构变化的研究进展，并指出了今后需要进一步研究的问题。
Drought tolerance mechanism of crops, the reaction of physiology biochemistry and the changes of ultrastructure under water stress were reviewed in this article.
植物对水分胁迫适应性的生理机理已相继在水稻、小麦、玉米、高梁等作物中得以报道。
Several physiological mechanisms affecting water stress adaption in plants including rice, wheat, corn, and sorghum have been reported.
