摘要
麦套花生不同时间不同次数喷施多效唑均具有明显地增产作用,而且当花生进入盛花期后,植株高度达到35厘米时,喷得越早增产效果越明显。其增产原因主要是控制了地上部旺长促进了荚果发育,提高了单株结果数,降低了公斤果数。
An field experiment was carried out for two years(1990-1991)in Teng County to study the effects of spraying PP333 on the yield and its components in summer peanut interplanted in wheat.The results Showed that this practice could increase peanut pod yield evidently.When the peanut reached the peak flowering stage while the plant reached about 35cm in height,the effects of spraying PP333 could reach the best.PP333 sprayed at the above stage could control the plant not too flourishing,promote pods development,increase pod number per plant,which was the reason of yield increase of peanut.
