摘要
黄腐酸拌种对晚播麦的出苗、麦苗地上部和地下部的生长均有明显的刺激作用,单株分蘖和次生根量比对照增加63.2%和52.0%。小麦临界期干旱时喷施黄腐酸(FA),能引起小麦叶片气孔开度减小,降低蒸腾失水量,缓和小麦体内水分亏缺的发展。
Seed-dressing by Eulvic Acid has an apparent stimulative role in the emer-gence of seedlings and the growth of the ground and under-ground parts of latesowing winter wheat.Tillars per plant and the bulk of secondary roots per plantincreased by 63.2% and 52.0% respectively in comparison with the control.Foliar applcation of fulvic acid can cause stomatal opening to decrease sothat water content loss by transpiration will be decreased and water regimes inplant body can be improved during the critical moisture period of wheat.
