喷施微肥对小麦产量、品质及籽粒微量元素含量的影响

摘要

以宁麦13为材料,在拔节孕穗期叶面喷施锌、铁和硒肥.喷施3种微肥对小麦产量结构、品质性状和铁含量均无显著影响,但显著提高了籽粒的锌和硒含量,锌含量提高了24.6％,硒含量提高了43倍.%The micronutrients zinc, ferrum and selenium were sprayed on the leaf surface at jointing and booting stage of wheat variety Ningmai 13. The results showed that the yield components, quality traits, and ferrum content in the grain were not significantly affected by these three kinds of micronutrients. But the zinc content and selenium content in the grain were improved greatly, and they were increased by 24. 6% and forty - three times respectively.
