不同时期喷施富硒液对小麦籽粒硒含量及产量的影响

Effect of Application Time of Selenium Fertilizer on Wheat Yield and Grain Selenium Content

通过在小麦孕穗期、灌浆前期、中期和后期,以叶面喷施富硒液的方式研究富硒液对小麦籽粒硒含量和产量的影响。结果表明,叶面喷施富硒液能显著提高小麦籽粒的硒含量,小麦穗粒数、穗重、千粒重有所增加,产量增幅达1.6%～8.5%。

By spraying liquid selenium fertilizer in earing stage, as well as in early, middle and later grain filling phrase, the effects of selenium application on wheat grain selenium content and yield were detecteed in the present investigation. The results showed that with the use of this fertilizer, the selenium content might be significantly enhanced. Also, small grain number per ear, grain weight per ear, and grain weight diversely increased by 1.6% - 8.5%.
