大丽花在栽培管理上有这样几个特点: ●喜温暖,怕炎热其适宜温度是20—25℃左右。春天15℃以上也可发芽生长,但夏季超过30℃时,就会生长不良,处于半休眠状态。因此在夏季高温季节,须将花盆放在凉爽通风处。●喜肥沃,怕过度以疏松、肥沃、排水良好的培养土为好。在生长过程中还要经常追肥,并逐渐加大肥料浓度。但浓度过高时又会造成烧根,故一定要适度。
Dahlia cultivation management has several characteristics: ● hi warm, afraid of the heat of its suitable temperature is about 20-25 ℃. Spring can also sprout more than 15 ℃ growth, but more than 30 ℃ in summer, it will grow poor, in a semi-dormant state. Therefore, in hot summer season, the flower pots should be placed in a cool and ventilated place. ● Hi fertile, afraid to over-loose, fertile, well-drained culture soil as well. In the growing process often topdressing, and gradually increase fertilizer concentration. However, when the concentration is too high will cause burning roots, it must be modest.
