摘　　要：　盆栽观赏果使用PP333进行处理,控制枝梢的营养生长,从而诱导观赏果反季节开花。试验结果表明,土施和叶喷PP333能有效抑制果新梢的萌发及生长,土施的抑制作用最明显,而叶喷的效果稍差,并且停止喷药一段时间后,新梢又开始正常萌发生长,两种处理果的开花时间都比对照提前约30天,并且花序数量增多,花序缩短。随着PP333用量的增加,这种变化越明显.<Abstrcat> Potted mango for enjoying after being treated with pp333,can be used to induce mango blossoming not only in April;for pp333 can restrain branches from vegetative growth.The research showed that spraying or mixing soil pp333 can effectively suppress branches sprouting and growing.But the inhibitory action of mixing soiling with pp333 is better than spraying.Moreover,after chemical spray for some time the young branches normally sprout and grow.Both of these two methods can make mango's time of flowering 30 days before the time of comparison.It appears inflorescence amount increasing and inflorescence reducing.The more pp333 is used,the more obvious the changes are.
