调查了多效唑(PP333)对塑料大棚栽培香蕉(Grande Naine 品种)的生长和产量的影响。花前2个月土施颗粒肥或叶面喷施1克 PP_(333)有效成分(a.i.)/株。显著降低株高、叶片大小和果穗长度,增加果实大小和果重。而对假茎围径、片叶数、吸芽抽生量、产量和果实成分没有影响。花前6个月土施(颗粒肥)0.5和1.0克 PP_(333)a、i、/株,明显降低株高、假茎围径和叶片大小,缩短果穗,降低产量,而对叶片数或吸芽抽生量没有影响。在不同施用方式和用量试验中,PP_(333)均增加叶片叶绿素含量,改善树冠内光强。PP_(333)对果实品质和成分没有明显影响。
The effect of paclobutrazol (PP333) on the growth and yield of banana (Grande Naine variety) grown in plastic greenhouse was investigated. Two months before the flowering soil fertilizers or foliar application of 1 g PP 333 (a.i.) / strain. Significantly reduce plant height, leaf size and ear length, increase fruit size and fruit weight. However, the diameter of pseudostems, leaf number, suction bud pumping capacity, yield and fruit composition had no effect. Six months before flowering, 0.5 and 1.0 g PP_ (333) a, i / L of soil application (granule fertilizer) significantly reduced plant height, pseudostem diameter and leaf size, shortened ears and decreased yield, while the number of leaves or Suction bud volume has no effect. PP_ (333) increased the content of chlorophyll in leaves and improved the light intensity in canopy in different application modes and dosage. PP_ (333) had no obvious effect on fruit quality and composition.
