通过田间试验与统计分析相结合的方法,研究了小麦出苗期土壤水分胁迫与施肥对小麦经济性状及产量的影响。结果表明:出苗期水分胁迫对小麦经济性状及产量产生极显著不良影响,可导致减产减收;与对照相比,几种施肥处理均能显著提高水分正常与水分胁迫小麦的某些经济指标和产量,但施肥弥补不了水分胁迫造成的严重产量损失。
The effects of soil water stress and fertilization on the economic characters and yield of wheat at the seedling stage were studied by field experiments and statistical analysis. The results showed that: Water stress at seedling stage had a very significant negative impact on economic traits and yield of wheat, which could lead to the decrease of yield and yield. Compared with the control, some fertilization treatments could significantly increase certain economic indexes and water deficit of wheat with normal and water stress Yield, but fertilizer can not make up for the serious yield loss caused by water stress.
