| 中文摘要: |
| 为探究叶面喷施硒肥对黑小麦籽粒产量和硒含量的效应，以临黑131和冬黑1206两个黑小麦品种为材料，分别在拔节期（4月17日）、孕穗期（4月28日）和灌浆期（5月14日）3个时期喷施0、10、20、30 mg·L-14个浓度的亚硒酸钠溶液，分析叶面喷施不同浓度硒对黑小麦籽粒产量及硒含量的影响。结果表明，拔节期和孕穗期喷施硒肥对黑小麦有增产效果，而灌浆期喷施硒肥增产效果不明显；孕穗期和灌浆期喷施硒肥浓度为10 mg·L-1至20 mg·L-1时，黑小麦籽粒可达到富硒标准（0.15～0.30 mg·kg-1）。综上所述，在黑小麦孕穗期叶面喷施浓度介于10 mg·L-1至20 mg·L-1之间的Na2Se03溶液，在不减少产量的前提下，可显著提高黑小麦籽粒中的硒含量，使黑小麦籽粒达到富硒水平，增加黑小麦的营养价值。 |
| 英文摘要: |
| In order to explore the effects of spraying selenium fertilizer on grain yield and selenium content of black-grained wheat, sodium selenite was sprayed on two black wheat cultivars:Linhei 131 and Donghei 1206 at jointing stage(April 17), booting stage(April 28) and grain filling stage(May 14). Four sodium selenite solutions were applied:0, 10, 20 and 30 mg·L-1.The results showed that spraying selenium fertilizer at jointing and booting stages could increase the yield of black-grained wheat, but spraying at grain filling stage did not show obvious effect. Spraying concentration at 10 mg·L-1 to 20 mg·L-1 at booting stage and filling stage made the black-grained seeds reaching the standard of selenium enrichment(0.15-0.30 mg·kg-1). Based on the study, it is preliminarily believed that spraying sodium selenite solution with a concentration of 10 mg·L-1 to 20 mg·L-1 on the leaf surface at booting stage can significantly increase the selenium content in the kernel of black-grained wheat without reducing the yield. Black-grained wheat reaches the selenium-rich level with the improved nutritional value. |
