我发现,蟹爪兰用海绵扦插,不失为简便实用的好方法。根据需要,用剃须刀从上下茎片的节间处切下所需茎片作插穗,或1节,或2~3节。插穗要求选取宽厚、饱满、青绿的成熟茎片,避免使用尚未成熟的嫩绿色茎片或表皮出现局部萎缩的老化茎片。将插穗下切口稍稍弄湿,蘸上市售生根粉,放入塑料袋中,封上口。置于阴凉处或冰箱冷藏室中备用。用生根粉最大的好处就是能大大缩短生根时间,且生根效果非常好。选择一块大小适中的海绵,用剃须刀在其表面纵向划出几道深沟,浸透水,置于盆中。盆里保持一定水位,以利海绵不断地吸水。翌日,将处理好的茎片有序地嵌入海绵缝隙中(见照),扶正,置于温暖的阳光下。插入茎片时,要避免基部相互叠压,嵌入深度也不宜太深,以免久不透气,造成局部溃烂。此后只需保持盆内始终有水,且水位不超过海绵表面就可以了。定期检查插穗基部,看是出现肿胀还是腐烂?前者是生根的前兆,后者需要及时用刀片和高锰酸钾清理创口。待生根后及时取出上盆。
I found that cuttlefish clams with sponge cutting, after all, a simple and practical method. If necessary, use a razor to cut the stems from the internodes of the upper and lower stems for cuttings, or 1, or 2 to 3. Cuttings require the selection of generous, plump, green mature stems, to avoid the use of immature green stems or epidermis of the skin appears to shrink aching stems. Will cut the incision under a little wet, dipped in commercially available rooting powder, into plastic bags, sealed mouth. Store in a cool place or in the fridge freezer. The biggest advantage of using rooting powder is that it can greatly shorten the rooting time, and the rooting effect is very good. Choose a moderate size sponge, with a razor in the surface longitudinal draw a few deep groove, soaked in water, placed in the basin. Basin to maintain a certain level, to facilitate sponges absorb water. The following day, the treated stems were sequentially embedded in the sponge gap (see photo), righting, and placed in warm sunlight. Insert stems, to avoid overlapping the base of each other, embedding depth should not be too deep, so as not to breathe a long time, resulting in local ulceration. After that simply keep the basin always has water, and the water level does not exceed the sponge surface on it. Regularly check the base of the cuttings to see if there is swelling or decay? The former is a precursor to rooting, the latter need to promptly clean the wound with a blade and potassium permanganate. After taking root, take out the pot on time.
