君子兰营养土怎么配?
君子兰营养土怎么配,君子兰为多年生肉质根草本植物,栽培土要求腐熟、疏松、透水透气、保水保肥、营养丰富、不含有害物质与病菌害虫,具微酸性,pH值在6~7,但现在没有一种土能同时具备这些条件。这就要求用多种材料,按一定比例,配制成君子兰培养土,进行栽培。
目前适合配制君子兰培养土的主要材料有:①腐叶土。包含阔叶土与针叶土两种。质地疏松透气,富含有机质,为酸性或微酸性。②田园土。肥力较高,团粒结构较好,但表层易板结,透气透水性差。③泥炭土或草炭土。富含有机质,质轻疏松,透气利水,保水保肥,呈酸性。④山泥。疏松质轻,透气利水,保肥保水。⑤塘泥。质地较硬,具有良好的抗旱与耐涝能力。⑥炉渣。质轻,疏松,多孔,含磷、钾营养元素,易于采集,以豆粒大小为宜。⑦河沙。质地纯净,排水通畅,呈中性,以高梁、小米大小为宜。
按照君子兰对土壤的要求与上述材料的性质,下面推荐几种君子兰培养土的调制方法,供莳养者参考选用:①腐叶土8份,炉渣、河沙各1份。②田园土、腐叶上各4份,炉渣或河沙2份。③泥炭土6份,河沙、炉渣各2份。④山泥、腐叶土各4份,河沙2份。⑤塘泥、腐叶土各4份,炉渣或河沙2份或各1份。
几种材料混合均匀后,用蒸或炒、硒等方法杀菌灭虫(卵),或用高锰酸钾溶液消毒,或用沸水淋透。晾干后再用筛或网过一过,上面粗的用做排水层,下面细的做栽培土,以上就是关于君子兰营养土怎么配的介绍。
