长期以来,热带兰组培苗的练苗问题一直使很多生产和科研单位大伤脑筋。往往由于练苗成活率低,而浪费了很多人力和物力。因此,本人愿将生产过程中获得的一点经验献给广大的热带兰爱好者。以下方法适用于石斛兰、万代兰、蝴蝶兰、文心兰和兜兰等。一、栽培基质用红砖碎粒、木炭碎粒和椰糠的混合物作栽培基质。先把直径5毫米左右的红砖碎粒垫在长方形塑料筐里,约3厘米厚,然后将直径2毫米左右的红砖碎粒(占47.5％)、木炭碎粒(占47.5％)以及椰糠(占5％)的混合物铺在上层,约6厘米厚。以上材料都要经过清水浸洗,以便消去红砖和木炭里的火气。二、洗苗用铁丝从培养瓶里把约3～5厘米的
For a long time, the problem of cultivating seedlings of tissue culture seedlings of Tropic Orchid has always caused many production and scientific research units to be greatly troubled. Often due to the low survival rate of seedlings, but wasting a lot of manpower and material resources. Therefore, I would like to dedicate a little bit of experience gained in the production process to the vast majority of tropical lovers. The following methods apply to Dendrobium, Bandai, Phalaenopsis, Oncidium and Paphiopedilum. First, the cultivation of the substrate with red brick nibs, charcoal nibs and cocoa mixture for planting substrate. First about 5 mm in diameter of red brick crushed mat in a rectangular plastic basket, about 3 cm thick, and then about 2 mm in diameter of red brick fragments (accounting for 47.5%), charcoal pieces (accounting for 47.5%) and coconut A mixture of bran (5%) is spread over the top, about 6 cm thick. The above materials have to be dipped in water in order to eliminate the red brick and charcoal in the anger. Second, wash the seedling with wire from the flask about 3 to 5 cm
