金盏菊可播种种植,选在春秋两季播种,选择颗粒饱满、充实的种子,浸泡温水促进种子吸水,之后晾晒到阳光下,将种子杀菌消毒,将种子播种到土壤中,等待幼苗生长,等幼苗长出三片以上的真叶时移栽种植。也可扦插种植,选在春季,将插穗剪下来,扦插到基质中促进生根,等生根稳定后,进行移栽种植。

一、播种种植
1、时间:金盏菊可在春秋两季播种,一般是在9月中下旬进行秋播。
2、种子:挑选好种子,选择颗粒饱满、充实的种子,将种子浸泡到温热的水中,大约浸水3-10小时,促使种子吸水膨胀,这样能利于发芽。浸水后,将种子晾晒到阳光下,将种子杀菌消毒。

3、播种:准备好疏松、透气的基质,将基质进行消毒,去掉基质中的病菌和虫卵。将种子播种下去,然后浸水来补充水分,可以覆盖上薄膜来保温保湿,幼苗出土后,及时把薄膜揭开,促进幼苗能够见光,拔除生长不好的小苗。
4、种植:等幼苗长出三片以上的真叶时,就可以移栽种植到盆土中了。

二、扦插种植
1、时间:金盏菊扦插一般是在春季,温度在18-25℃左右,能利于扦插成活。
2、插穗:选择生长良好的金盏菊植株,从上面剪下粗壮、没有病虫害、长势好的枝条作为插穗。

3、扦插:准备好透气性好的基质,将插穗扦插到基质中,注意养护促进生根。
4、种植:等金盏菊的插穗生根稳定后,可以准备好合适的盆土,将生根的小苗进行移栽种植。
金盏菊的养殖方法:
1、土壤:不择土壤,以肥沃、疏松和排水良好的沙质壤土或培养土为宜,土壤pH以6-7最好。这样植株分枝多,开花大而多。
2、阳光:春夏秋三季需要在遮荫条件下养护。在气温较高的时候(白天温度在25℃以上),如果它被放在直射阳光下养护,叶片会明显变小,枝条节间缩短,脚叶黄化、脱落,生长十分缓慢或进入半休眠的状态。冬季就要给予直射阳光的照射,以利于进行光合作用和形成花芽、开花、结实。
3、温度:喜欢温暖气候,最适宜的生长温度为15~25℃,忌酷热,在夏季温度高于34℃时明显生长不良;不耐霜寒,在冬季温度低于4℃以下时进入休眠或死亡。
4、施肥:定植后7-10天,摘心促使分枝或用0.4%比久溶液喷洒叶面1-2次来控制植株高度。生长期每半月施肥1次,或用“卉友”20-20-20通用肥。肥料充足,金盏菊开花多而大。相反,肥料不足,花朵明显变小退化。
5、虫害:室内栽培因通风差、湿度大,常发生枯萎病和霜霉病危害,可用65%代森锌可湿性粉剂500倍液喷洒防治。初夏气温升高时,金菊叶片常发现锈病危害,用50%萎锈灵可湿性粉剂2000倍液喷洒。早春花期易遭受红蜘蛛和蚜虫危害,可用40%氧化乐果乳剂1000倍喷杀。
6、修剪:每两个月剪掉一次带有老叶和黄叶的枝条,只要温度适宜,能四季开花。
金盏花很好养的,苗期盆土稍湿润点,通风和光照一个也不能少,长大了可以间干间湿的养,金盏菊喜耐寒,怕热,喜阳光充足环境,尤其冬季露地育苗或棚式栽培,均需充足日照,这样对茎叶生长十分有利,幼苗生长矮壮、整齐。如过多雨雪天,光照不足,基部叶片容易发黄,甚至根部腐烂死亡。土壤以肥沃、疏松和排水良好的沙质壤土或培养土为宜。土壤pH以6~7最好。这样植株分枝多,开花大而多。
金盏菊为菊科一、二年生草本花卉,高30~60厘米,花色淡黄至深橘红色,花期4~6月,是重要的春季花卉。
喜阳光充足,也稍耐阴,喜夏季冷凉,不耐炎热,但较耐寒,尤以小苗比大苗较耐低温。适应性较强,较耐干旱瘠薄,但在疏松、肥沃的土壤上生长良好。
金盏菊通常作二年生栽培。华北地区秋播在9月上中旬播种,约1周出苗,10月下旬在冷床假植越冬。金盏菊生长快,茎粗叶大,早春要及时分栽定植,4~5月可开花。春播在2~3月于温室播种,6月开花,在高温的夏季生长不良,开花较少,可及时剪除残花,秋季还可继续开花。
采种用的金盏菊,要注意施肥,否则容易退化。能自播繁衍,种子生活力为3~4年。
金盏菊花色多样,以金黄色和橘红色常用,观赏效果较好。
金盏菊早春开花,色彩艳丽,大量用作花坛的材料,也可作切花或盆栽。
