菊花怎么养

一、养殖环境



1、土壤:最好用疏松、排水性较好的沙质土壤,选择酸性土壤最佳。

2、浇水:在干旱天气时要及时浇水,在雨季天气要及时排水;在孕蕾前后阶段要保证充足的水分,土壤不能过干或过湿;如果因为浇水量大导致积水出现,要及时采取排水措施,以免出现烂根。

3、施肥:在生长期间要保证充足的养分,以氮肥为主,磷钾肥为辅。这可以使菊花的枝条更加健壮,在施肥后要适当浇水。

4、光照:每天给它12小时左右的光照,但是不能让它被强烈的阳光照射,否则可能会缩短它的花期。

二、繁殖方法

1、扦插繁殖:把插穗插到盆土中,将土壤压实,扦插完后适量浇水,维持花土湿润,白天最好将花盆放在室内,以免被强光照射。

2、分根繁殖:把母株挖起,选择根须多的菊苗取下栽种,之后将土压实并适量浇水即可。

三、常见病虫害

一般常见的病虫害为褐斑病、白粉病、蚜虫等,多是因为光照不足、没有通风、昼夜温差大引起的,可以用多菌灵等药剂防治,平时也要注意加强通风,给它充足的光照。
