凯特杏幼树营养生长旺盛，单一靠修剪技术难以实现早期结果丰产，在科学合理修剪的基础上，应用植物生长抑制剂 PP333进行调控，结果表明：凯特杏施用 PP333后，新梢长度明显降低，粗度增加减缓，节间短，花芽数明显增加，单果质量增加明显，单株产量显著增加；施用植物生长抑制剂 PP333能促进凯特杏幼树由营养生长向生殖生长转化，提高产量和经济效益。
凱特杏幼樹營養生長旺盛，單一靠脩剪技術難以實現早期結果豐產，在科學閤理脩剪的基礎上，應用植物生長抑製劑 PP333進行調控，結果錶明：凱特杏施用 PP333後，新梢長度明顯降低，粗度增加減緩，節間短，花芽數明顯增加，單果質量增加明顯，單株產量顯著增加；施用植物生長抑製劑 PP333能促進凱特杏幼樹由營養生長嚮生殖生長轉化，提高產量和經濟效益。

The vegetative growth of saplings for Prunus armeniaca L.‘Katy’are vigorous;vegetative pruning tech-niques are difficult to achieve bearing and high-yielding.In a scientific and rational pruning,Prunus armeniaca L.‘Katy’was conducted regulation by applying plant growth inhibitors (PP333).Result shows that:after Prunus ar-meniaca L.cv.Katy was applied PP333,new shoot length are significantly lower,the increase of roughness slow down,internodes are shorter,the number of flower buds increase significantly,per fruit weight increase significant-ly;yield per plant increase significantly;the saplings of Prunus armeniaca L.Katy can be converted from vegetative growth to reproductive growth by applying PP333;the yield and economic benefit of Prunus armeniaca L.Katy can be increased by applying PP333.
