梅花什么季节开花
梅花什么季节开花,中国西南地区12月至次年1月,华中地区2~3月,华北地区3~4月开花。初花至盛花4~7日,至终花15~20日。
如何让梅花在元旦开花?梅花花芽分化完成以后,为控制其花期,可将盆栽梅花放在室外,直至深秋,经过露天低温,使花芽得到充分休眠,在小雪前后移到低温房间,花芽即可逐渐膨大,这时可进行花期控制,一般可控制在元旦、春节开花。
要使梅花在元旦开花,到了小雪梅花入室后室温保持在4℃左右,于12月中旬将盆梅移到室温为15~25℃的阳光充足之处,不干不浇。每天浇水1次,届时即可见花,要使梅花在春节开花,小雪人室后室温保持在4℃左右,春节前7~10天,放人15~20℃的室内,春节即可开花。
梅花加温应注意几点:一是室温不可急骤增加,需逐渐升高,不然往往因叶芽萌发而落蕾,影响开花;二是加温时须同时给予充足的阳光,否则花色较淡,影响观赏价值;三是温度升高后,浇水要均匀,不可过干或过湿,否则花色变淡,花朵小,且容易落蕾、落花,并要注意经常喷水;四是含蕾待放时,施以少量速效性氮肥和磷钾肥,以上就是关于梅花什么季节开花的介绍。
