| 摘 要： | 为明确灌水与施用钾肥之间的互作效应,本研究采用不同灌水次数与钾肥用量设计,研究了灌水与钾肥施用对旱地冬小麦后期生长及籽粒灌浆的影响.结果表明,适当的灌水次数及钾肥投入,能提高旱地冬小麦旗叶的叶绿素含量、光合速率及小麦籽粒千粒重;灌水与施用钾肥之间有一定互作效应.

| Abstract: | To study the interact effect of water irrigation and potash fertilizer,designs of different times of irrigation and different levels of potash fertilizer were carried out.Results showed that the increase of times of irrigation and the increase of potash fertilizer made the effect of increasing flag leaves chlorophyll content,photosynthesis rate and 1000-grain-weight.Some kind of interaction between water irrigation and potash fertilizer do exist. |
