摘要
试验结果表明 ,小麦拔节期叶面喷施 MFB多功能抗旱剂可使小麦产量提高 6.8%～ 2 2 .9%,平均增产达 1 3 .95%,与对照相比差异显著。喷施 MFB多功能抗旱剂还可改善小麦籽粒营养品质 ,与对照相比 ,小麦粗蛋白含量、面筋含量和赖氨酸含量分别增加 0 .98、3 .77和 0 .0 7个百分点。小麦增产的原因是喷施 MFB多功能抗旱剂可使小麦千粒重、穗数和穗粒数增加 。
The experiment carried out by the authors gave us some evidences that wheat grain yield could be increased by 6.8%~22.9%(with an average increase of 13.95%) when MFB drought tolerance agent was sprayed at jointing stage. Simultaneously, the grain quality had also been improved as its protein content, gluten content and lysine content were increased by 7.38%, 12.68% and 20%, respectively. Further study revealed that spray MFB could increase 1000 grain weight, ear number per m 2 and grains per ear and improve stress tolerance of wheat plant. Hence, MFB could significantly increase wheat grain yield.
