摘要
该试验采用对比法田间设计,冬小麦起身期用20％壮丰安微乳剂500倍液叶面喷雾。结果表明,小麦成熟期茎杆基部三节长度比对照平均缩短1.72cm,茎杆平均增粗0.11mm,茎杆壁平均增厚0.2mm。提高了小麦抗倒能力,应用壮丰安进行化学调控是实现小麦公顷产量7500kg的稳产措施之一。
Zhuangfengan emulsion at concentration of 400 mL/L was applied on winter wheat at elongation stage. Results showed that the length of the bottom three nodes at harvesting time was reduced by 1.72cm, and stem diameter increased by 0. 11 cm, stem wall increased by 0. 2 cm compared with check treatment. Lodging resistance of winter wheat was increased. The application of Zhuangfengan is an important practice for maintaining wheat yield of 7500 kg/ha.
