早春时节促成栽培的黄馨(大花迎春)和重瓣榆叶梅,花后均需强修剪。因为这类花木花芽形成在当年新枝上,老枝不会或极少形成花芽。修剪时在健壮的开过花的枝条基部留3~4个潜伏芽,将上部已开完花或已有幼芽或已形成新枝的部分剪除。同时把一些未开花的弱枝、残枝由基部剪除,不留基部潜伏芽,因为这种部位的潜伏芽萌发后仍为弱枝,不能良好地生长开花。健壮新枝长至10~20厘米时,将过强枝短截,过弱枝由基部剪除。 Early spring to promote cultivation of yellow Xin (large flowers Yingchun) and double-flowering Prunus triloba, flowers are required pruning. Because this type of flower buds formed in the new year branch, the old branch will not or rarely form flower buds. Pruning in the sturdy branches of the flowers spent leaving 3 to 4 latent buds, the upper part of the flowers have been finished or buds have been formed or new branches cut off. At the same time some of the flowering of weak branches, branches cut off from the base, leaving the base of the latent bud, because this part of the latent bud after germination is still weak branches, not good growth and flowering. Sturdy new branches grow to 10 to 20 cm long, will be too strong branches stubby, weak branches cut off from the base.
