盆栽桂花嫩叶期如用肥过量,即会灼伤叶和芽,影响全年的生长和观赏。这种用肥不慎的受害现象,每年春季各地都有发生,多出现在初养者身上。图片所示的,就是用肥过量后叶面受到的不同程度的伤害。如图1的几株桂花,叶面皱缩瘪凸,色泽光度浅褪,叶缘不规则状残缺,小枝细,形成的腋芽叠数少且瘦弱,叶数减少。图2是受害的3年生小型桂花,只剩个别的叶完整。图3是大龄的中型桂花,多数叶皱瘪不展或畸状皱卷。图4是老龄大株受害后出现的局部伤残状。无叶的小枝,叶片是受害后几日内脱落的,剩存的也不整不壮,腋芽弱,呈发育不良状。色淡质薄的大叶是受害后晚发的。以上图片均是秋后所拍,也就是说植株受害后虽经从春到秋的精细养护,各伤残部分并未能得到恢复,已经直接影响着来年的发育生长。 Potted Osmanthus leaves such as excessive use of fertilizer, which will burn leaves and buds, affecting the annual growth and ornamental. This phenomenon of inadvertent victimization of fertilizers occurs every spring throughout the year and occurs mostly in early adopters. As shown in the picture, different degrees of damage to the foliage are caused by excessive fertilizer. As shown in Figure 1 a few osmanthus folds shrink convex, color light faded, irregular edge rupture, small branchlets, forming a small number of axillary buds and thin, the number of leaves reduced. Figure 2 is a victim of 3-year-old small sweet-scented osmanthus, leaving only a few leaves intact. Figure 3 is the older medium-sized sweet-scented osmanthus, the majority of leaf folds or no wrinkles or abnormal wrinkles. Figure 4 is the elderly after the damage caused by local injury. Leaves without leaves, the leaves are off within a few days after the victim, the remaining is not the whole is not strong, weak axillary buds, was dysplastic. Thin, light-colored leaves are harvested late late. The above pictures are taken after the fall, which means that after the plant was harmed by the careful maintenance from spring to autumn, the disabled parts have not been restored and have a direct impact on the development and growth of the coming year.
