1989—1990年试验结果表明,小麦拔节期每亩喷30克矮壮素,缩短了第一、二节间的长度,株高降低,可防止或减缓倒伏,叶面积增大,叶功能期延长,干物质积累增加,穗粒数增多,千粒重提高,亩增产小麦25—64公斤,增产率7.7—21.8％。
The results from 1989 to 1990 showed that spraying 30 grams of CCC at the jointing stage of wheat reduced the length of the first and the second internodes and decreased the height of the plant to prevent or slow down the lodging and the increase of the leaf area and the prolonged leaf function , Increased dry matter accumulation, increased grain number per spike, and increased grain weight per acre. Acreage of wheat increased by 25-64 kg and yield rate increased by 7.7-21.8%.
