摘　　要：4年多对壮丰安在小麦上的应用研究表明:冬小麦单棱期喷施壮丰安的适宜剂量为450～535ml/hm^2;施用壮丰安后,小麦基部3节节间长度缩短,单位长度干重增加;上部3节节间长度略有增加,单位长度干重下降;小麦的抗倒伏能力增强,增产5％～15％,在产量构成三因素中,群体增加3％～5％,千粒重增加3.4％,穗粒数增加4.0％。壮丰安可显著提高小麦灌浆后期的灌浆速度。Over 4 years research oi the application ol Zhang-r eng-An on wheat showed that the best dosage of spraying Zhuang-Feng-An at single-ridge stage of winter wheat is 450-535 ml/hm2.After application, the length, of node was reduced and the dry weight per unit of length was increased for the 3 bottom stems, while the length of node was increaased and the dry weight per unit of length was reduced for the 3 top stems. Lodging resistance of wheat was increased, and yield was increased by5%-15% .Of the three yielding factors, the population was increased for 3%-15%, thousand kernels weight was increased by 3.4%, kernel number per spike was increased by 4% . Milky speed at the later milk stage of wheat was significantly increased .
