摘要
花生叶面喷施稀释1000倍的黄腐酸(FA)溶液可以增加花生的单株有效花量和单株根瘤数,使叶片叶绿素含量提高,果针提早入土,加快果针膨大,提高花生饱果率,增加荚果产量。喷施试验结果表明,以苗期、始花期、下针期3次喷施黄腐酸效果最佳,其次为始花期和下针期2次喷施黄腐酸的处理,而只于苗期1次喷施黄腐酸的处理效果不明显。
Foliar application of FA solution (1:1000) was conducted at three different periods. It was discovered that FA could increase number of productive flowers per plant, number of noduls per plant, leaf chlorophyll content and pegs to enter to soil earlier, accelerate pegs expensding, raise well-filled pod rate and yield. As far as the effects of FA on growth on groundnut were concerned, treatment I(were applied three times at three different periods) came first, treatment II(were applied two times at two different periods) was followed.
