怎样科学培养文竹

培养#文竹 需掌握以下技术要点:

①光照与温度。文竹喜阴凉湿润环境,在散射光下生长较好。夏季怕强阳光,故应放置在通风半阴处,否则会造成枝叶发黄,叶片脱落。冬季不耐霜冻,在秋末应搬到室内向阳处,室温保持在5℃以上,就能安全越冬。

②水分。盆土要于湿相宜,长期干旱会使叶尖焦黄,而过湿易使根部腐烂,叶黄脱落。天气干燥时,需向叶面及地面喷水。水要浇透,不干不浇,以不积水为宜。同时浇水忌用“洒水法”,以免造成表湿里干。

③肥料。为了不使植株过高,在生长期间,施肥不必太勤太浓。一般春秋季节每隔10天施1次肥。夏季气温高,应停止施肥,以免烂根。入冬停止施肥。

④土壤。盆栽文竹要求盆土疏松、排水良好。常用园土和腐叶土各半,或加少量砻糠灰配制。

⑤文竹一般2年换盆1次,使植株与盆的大小适宜,同时换上疏松、富有营养的盆土,并需保护好原有植株的护心土,使文竹能更好地生长。


拓展:文竹应怎样科学管理

文竹的栽培介质可以用等体积的壤土和腐殖土混合而成,可在2-3月份换盆,1个月以后可进行追肥,氮和钾肥的比例可以略高一些。花盆应置放在有散射光的地方,冬季应放朝南向阳房间,室温不低于5℃便可安全越冬。盆内土壤以湿润状为最佳。





顺道说下,文竹新枝嫩头枯焦怎么办?

文竹的生长期在春、秋两季,初夏新长枝叶尖端枯焦的原因较多,主要是盆土过干,或氮肥不足,施人了浓肥或“生肥”,而造成嫩头枯焦。另外,文竹属攀缘植物,长高时,必须有支柱或绳索,让它引索而上。否则,由于顶梢弯曲下垂,影响水肥供应,也会发生枝叶顶端的枯焦等情况。文竹在生长期,宜放置在通风的半阴处,盆土宜湿一点,不要断水,还可施人以氮为主的块粒肥料,或吃剩的牛奶瓶残汁掺水后浇水。这样,文竹就能生长茂绿,青翠欲滴,惹人喜爱,嫩头枯焦现象也可以避免。
