鸡蛋花怎么养
鸡蛋花怎么养:
【生活习性】
鸡蛋花性喜高温、高湿、向阳和肥沃、通气、排水良好的土壤。
【繁殖技术】
主要采用扦插繁殖,也可用分株或播种繁殖。其扦插方法是春季发叶前选取1~2年生健壮无病虫害的枝条,剪截成长10~15厘米的插穗,放置于阴凉通风的地方,待切口干燥后,直接插入沙床内,插入深度为3~4厘米,插后保持基质湿润,但要防止水分过多。在20℃条件下20天左右生根。
【栽培管理】
生长季节要有充足的水分供应。浇水一定要浇透,浇到盆底出水为止,保证根团完全湿润,并对土壤进行淋溶,以冲走其中有害物质,同时应注意盆内勿积水以免烂根。冬季落叶后要控制浇水量,以免出现烂根。室内摆放的植株在生长季节除浇水外,还应每天对叶片喷水,保持局部空气相对湿度和叶片的清洁。生长季节每15天浇施1次尿素和磷酸二氢钾等量配制并添加少量微肥的稀薄液肥。
入秋后可追施1次磷、钾肥,以提高植株的抗性为越冬做好准备。每年春季植株新叶萌发前换盆,换盆时换去70%左右的旧土,剪去枯老根,并对植株做适当的修剪,剪下的枝条可用于繁殖。从小盆逐步换成大盆。换盆或新移栽后盆土宜保持见干见湿,干湿交替,以增加土壤的透气性,促进根系生长。
鸡蛋花主要病害有褐斑病和叶斑病。防治方法:施足基肥,注意平衡施肥,提高植株的抵抗力,及时清除病叶,并集中烧毁;在褐斑病发病初期用65%甲基硫菌灵500倍液,或50%多菌灵可湿性粉剂800倍液防治,15天1次,连喷3~4次。叶斑病发病初期用65%代森锌可湿性粉剂800倍液,或75%百菌清可湿性粉剂500倍液防治,15天1次,连喷3~4次,以上就是关于鸡蛋花怎么养的内容。
