产生幼弱兰花小苗的原因有:经兰种发育长成的龙根实生小苗、兰株被伤害及非正常死亡后经假鳞茎再发育长成的幼弱小苗等。这种小兰苗抗病能力差,成活率低,又不易栽培,一般没7—8年很难开花。所以栽培这种小兰苗一定要有目的地加以选择。如:名贵珍稀兰品的再生小苗、奇花叶艺的定向栽培苗及认为有较高栽培价值的无花无艺的实生无名小苗。初得小苗,不管哪类品种,都应先修剪残根败叶,用清水将根叶泥土及残迹冲洗干净,再用0.5％的托布津或其他杀菌剂(浓度稍淡些)将兰苗全浸5—10分钟(不宜太久),稍稍摆动,提起倒挂阴干。待根系微泛白有一定发软可塑性后,即可上 Reasons for the emergence of inflorescence orchid seedlings are: the growth of blue seedlings grown Longgen seedlings, blue plants were injured and abnormal death after growth and development by the pseudobulb bulblets and so on. This small blueberry disease resistance is poor, low survival rate, but not easy to cultivate, generally not 7-8 years difficult flowering. Therefore, the cultivation of this small blue must have a destination to choose from. Such as: precious rare orchid regeneration of seedlings, flowers and directional cultivation of rare flowers and that there is no higher value of cultivation of flowerless real seedlings. Early seedlings, no matter what kind of species, should be pruning leaf decay leaves, roots and leaves with water to soil and residue rinse, and then 0.5% of Topis or other fungicides (slightly less concentration) will be all-blue seedlings dip 5-10 minutes (should not be too long), a little swing, raised upside down dry. To be slightly whitish roots have a soft plasticity, you can
