鹤望兰虽系原产南非亚热带地区的珍奇名贵花卉、习惯了温暖湿润的环境条件,但在我国北方地区作为温室盆栽花卉也能生长良好。一、用盆与营养土的配制鹤望兰的根系粗壮肥大.开花植株使用大而深的盆或木桶为宜。营养土配制以“三合土”为好.即用一份腐殖土、一份壤土(或草碳土),再加一份粗如蚕豆粒大小的炉渣混合而成;也可用菜园土2份.腐叶土1份和粗沙1份混和均匀配制。上盆时盆底铺一层粗粒炉渣(或粗沙)以利透气排水。盆土填至一半时,可在盆边和没有根系的空隙内放入少量发酵良好的饼肥块。然后继续填土到距离盆沿5至7厘米即可。二、光照与温度鹤望兰是阳性植物,喜欢充足的阳光,但是夏季室外要用稀疏的苇帘或竹箔片遮挡中午直射的强光,以免灼伤叶片影响观赏价值;春秋季节应放置阳光充足处;冬季进入室内要尽量放置靠近向阳的窗口,以充分接受阳光。如果平均气温不低于十五摄氏度.夜间短时温度不低于五摄氏度,冬季依然边开花边抽生花薹,只是生长速度较慢而已。三、浇水与施肥鹤望兰怕旱忌涝,浇水应随季节和生长情况及土壤干湿度而定。盆土欠水常导致叶片卷曲和叶缘焦枯萎缩。夏季根据天气状况每天必须浇水一次,且早晚用清水喷洒叶面及周围地面,以增加空气湿度。冬季一般五至七天浇一次水。雨季只要花盆底部排水孔通畅.不必倾盆避雨。每次浇水均要认真浇足浇透.既保证植株对水
Strelitzia reginae is native to South Africa’s subtropical rare and exotic flowers, accustomed to warm and humid environment, but in northern China as a greenhouse potted flowers can grow well. First, the use of pots and nutritious soil preparation Strelitzia root thick stout flowering plants using large and deep basin or barrel is appropriate. Nutritional soil preparation to The use of a humus soil, a loam (or grass carbon soil), plus a coarse, such as bean-sized slag mixture; also available garden soil 2 1 part of leaf mold and 1 part of coarse sand mixed evenly. Put a layer of coarse slag (or coarse sand) on the bottom of the basin to facilitate ventilation and drainage. When filling up half of the basin soil, a small amount of well-fermented cake cakes can be placed in the basin and in the absence of roots. Then continue filling to 5 to 7 centimeters away from the basin. Second, the light and temperature Strelitzia is a positive plant, like plenty of sunshine, but the summer outdoor reed curtains or bamboo with a thin glass to block the light at noon, so as not to affect the ornamental value of leaves burns; Spring and Autumn should be placed in sunny Department; winter into the room to try to place close to sunny window, in order to fully accept the sun. If the average temperature of not less than fifteen degrees Celsius at night short-term temperature of not less than five degrees Celsius, winter is still blooming side of the flowering flower stalks, but slower growth only. Third, watering and fertilizers Strelitzia fear drought drought, watering should be season and the growth and soil moisture and humidity may be. Potted soil water often lead to leaf curling and fringe cobweb shrinkage. In summer, it is necessary to water once a day according to the weather conditions, and spray the foliage and the surrounding ground with water to increase the humidity of the air. Winter water generally poured five to seven days. Rainy season as long as the drainage hole at the bottom of the pod smooth. Watering should be carefully pouring enough water each time
