1995年7～9月,因长江中下游一带持续高温干旱,许多在阳台养护多年、用扦插法繁殖的蟹爪兰,都相继干瘪、枯黄、萎蔫而死,而利用仙人掌作砧嫁接繁殖的蟹爪兰则大多安然无恙。究其原因,蟹爪兰喜较为凉润的环境条件,尤其夏季要遮荫避雨,置放于通风良好的阴凉处。而去年夏天阳台上盆土表面温度高达45℃,室内气温亦接近40℃,如此超常的炎热烘烤其扁平肉质茎,必然会生长不良,乃至奄奄一息。相比之下,以仙人掌作砧嫁接的植株,因由仙人掌代为受烤,故能明显抵卸炎热的侵袭,这不能不说得益于仙人掌发达的根系和其对炎热干燥环境的适应
From July to September 1995, due to the continuous high temperature and drought in the middle and lower reaches of the Yangtze River, many crabgrass cultivated on the balconies for many years and propagated by cutting method were successively shriveled, withered and wilted, while the crabs Most claw orchid is safe and sound. The reason, crab claw Lanxi more cool environment conditions, especially in summer shade, placed in a well-ventilated shade. Last summer, the basin surface temperature on the balcony up to 45 ℃, the indoor temperature is also close to 40 ℃, so unusual hot baked flattened stalk, inevitable growth, and even dying. In contrast, the cactus for the anvil grafted plants, because by the cacti on behalf of the roasted, it can be significantly offset the hot invasion, which can not be said to benefit from the cactus developed roots and its adaptation to hot and dry environment
