摘要/Abstract

摘要： 冬前至孕穗期不同生育期追施肥水，对根系的影响不同。追施肥水可提高根系活性，早施，根系活性最大值出现得早，后期根系活性降低得也快。开花、灌浆期的根系活性均以拔节、孕穗肥水为高。根系活性对叶片衰老速度有明显的影响，与上部干重、产量及产量性状存在着密切的关系。

Abstract: The experiment was carried out from 1982 through 1986 to investigate the effect of top-dressing and irrigation time on the characteristics of the root system and aboveground parts of winter wheat. The results indicated that different top-dressing and irrigation time had different effect.The applicat
