- Title:
- Interactive Effects of Mineral Nutrients and Water Stress on the Growth, Development and Yield Components of Spring Wheat
- 摘要:
- 营养缺乏和水分胁迫各自对春小麦的生长发育和产量形成有直接影响.分析了春小麦的植株水分状况、生育期、叶片生长、干物质积累和产量构成等在受到水分胁迫下的变化后,认为在一定水分胁迫条件下增加无机营养,能促使春小麦绝对产量显著增加;生活在营养缺乏条件下的春小麦则能产生一系列适应于干旱环境的性状,遇到水分胁迫时受到的影响相对较小(营养充足条件下水分胁迫使产量下降的比率大于营养缺乏条件下的比率).据此如何掌握各种不同程度干旱下的施肥技术,既能使作物维持必需的生长量,同时又能抵御一定程度的水分胁迫,是一个值得进一步研究
- Abstract:
- Both mineral nutrient deficiency and water stress have direct effects on the growth,development and yield of spring wheat.Changes of plant water relations,developmental periods,elongation of leaves,accumulation of dry matter and yield components,which was resulted from mineral nutrient deficiency and/or water stress,were determined.It can be concluded that under certain water stress the absolute yield of spring wheat increases significantly with the increasing of mineral nutrient.The spring wheat under mineral nutrient deficiency could be obtained a lot of characteristics to adapt to drought.When water stress occured under mineral nutrient deficiency,the influence on spring wheat would be smaller than that under enough nutrient supply.(The proportion of yield decrease under enough nutrient supply was more than that under nutrient deficiency when water stress occured).It follows that how to determine the fertilizing technique with which the crop can maintain necessary growth as well as resist moderate water stress under water stress,is a problem to study progressively.
