对限水条件下冬小麦的生长发育状况作了研究。结果表明：水分胁迫条件下植株生长受阻，绝对生长速率减慢，小麦生育后期绿叶面积迅速衰减，光合强度下降，早衰严重；研究发现，绿叶面积的稳定时间与灌水时间具有“临近效应”；穗下茎可作为土壤水分状况的良好指示性状。
The growth and development of winter wheat under limited water conditions were studied. The results showed that under water stress, the growth of plants was blocked and the absolute growth rate was slowed down. The area of green leaf declined rapidly at the later growth stage of wheat, photosynthetic intensity decreased and the premature aging was serious. The study found that the stabilization time of green leaf area and irrigation time had “near effect” The lower stem can be used as a good indicator of soil moisture status.
