首先,你要确定自己的桂花选择对了。有一种称为紫桂的桂树,只有长成了大树之后才会开花,所以,在选择桂树品种的时候要小心,要和卖家确定这种桂树盆栽是可以开花的时候才能入手哦〜
选择桂花种苗的时候,最好是选择以良种成熟枝作为接穗的嫁接苗,或在带花的枝条甚至基部通过高压法收回来的苗,完全质好,成活后容易开花。
2你的桂树到了开花的年龄了吗?
确定好了自家桂树没有选错之后,接下来,就要看你家的桂树是不是已经到花龄了呢?桂树的寿命很长,基上能够生存几十年到几百年,甚至上千年的也有,桂树如果不到年龄是不会开花的哦〜
播种的实生苗要十年左右开花; 010- 140005的要四年开花;嫁接的金桂银 桂到次年有五分之一开花;嫁接的四季桂虽然当年开花但为数很少。
移栽的大桂花树有的当年可以开花,有的要适应一,两年才开花。
Of course, the last big 桂 flower tree, unless there is a big yard at home, or give up.
3 桂树 daily maintenance, you have done it.
1. Entering the room too early in winter will result in 桂树 not blooming.
Planting 桂 The wintering temperature is 3~5°C, and it is not necessary to enter the room above 3°C to maintain the natural temperature; when it is below 3°C, it enters the room. After entering the room, it will be dormant at low temperature, and it will grow vigorously the next year, with flowers 叶茂.
2. After the spring out of the room, the wind is blowing and the sun is dry. Even if the sprouts are re-emerged, it is not easy to flower.
It should be moved out on a cloudy or rainy day, and it should be avoided that the room is suddenly 暴晒, so it should be gradually adapted to the outdoor environment.
3, do not change the pot in time
Some potted plants 桂 flowers, changed the soil for a few years, resulting in insufficient nutrition, root knots can not stretch, affecting flowering. Therefore, the 桂 flower needs to be changed once in two or three years. The basin should be completed before March, because this time is the dormancy period of 桂 flower, and the effect of changing the pot on 桂 flower is small.
4, 光照 Insufficient
桂 Hua Xiguang, 桂 flower takes more than 10 hours 光照, otherwise the leaves are not flourishing, affecting flower buds and not flowering.
5, too much watering
Excessive watering will cause rotten roots and fallen leaves, affecting flowering. Watering should follow the principle of “do not dry, do not pour, pour and pour out”. After heavy rain and heavy rain, it is necessary to remove the water in the basin in time.
6, excessive nitrogen fertilizer, insufficient phosphorus and potassium fertilizer, so that the branches and leaves are long, affecting flowering.
The application of phosphorus and potassium fertilizers can promote their transition from vegetative growth to reproductive period.
在春季发芽期,必须使用完全分解的饼肥和其他有机肥。 7月后,施用磷基肥料或在肥料中添加0.5%的过磷酸钙。促进花蕾生长。
桂花需要更多的磷和钾肥,并且可以在根部外追肥,在叶子上喷施0.1%-0.2%的磷酸二氢钾。
7,灰尘和油脂污染。
桂花不耐烟灰和油脂,叶子长时间受烟灰和油脂污染,生长不良,甚至落叶,影响开花。可以用细纱布轻轻测试叶片以保持叶片清洁,并每15天擦拭一次,以促进光合作用并使植物生长健壮。
8,缺少修剪。
桂花根发达,出芽力强。如果修剪不当,则叶子太密并影响开花。因此,在离开房间之前,有必要修剪弱枝和密枝,并根据植物的形状将其短切,以便通风和透光,并促进其开花。
但是要小心,错误地切开春笋会影响一年的开花。盛开的桂花枝过多会削弱其生长并在将来影响开花。
9,桂花是弱酸性土壤,pH值优选为5.5-6.5。在碱性土壤中生长的桂花通常生长较差并影响开花。
桂花树养分土壤通常使用四个公式:
1。泥炭土78%-88%,堆肥堆肥10%-20%,过磷酸钙2%。
2。泥炭土和黄土分别为1/2。
3。泥炭土:花园土或黄土,比例为1:1或1:02。
4。土壤或肥料的98%,过磷酸钙或钙,镁,磷,钾肥约占1%,然后添加适量的杀菌,杀虫农药。
10,桂花树易患炭疽病。
可以用700%至800次的80%锰锌可湿性粉剂(大生)或1%半量式 波尔多溶液或75%百菌清 500倍的溶液进行喷雾。预防和治疗。
如果已经病倒,请迅速切掉患病的叶子,掉下枯死的树枝等,并及时燃烧以增强通风。
11,桂花树易受诸如鳞虫之类的害虫侵害,并且未及时处理,这也会影响开花。
发现了一种规模较大的昆虫,可以用酒精反复擦拭患病植物,并且清除非常干净。
好吧,挂花树不开花的大部分原因都在这里〜
