我特别喜爱兰花。从退休至今,栽培下山兰12年,经历几次失败、成功,多少有点栽管经验。可去年秋又碰到了新问题,且碰得“鼻青脸肿”。12盆蕙兰,前些年,年年开花。而2003年冬一个蕾也没有,虽心中纳闷,但还是自我安慰,等来春再看。然而2004年春夏,依然如故,朵花不见。逼得我回过头来检查一年中养护中的问题。同时,认真阅读花卉报刊的有关文章,探索不孕原因及其理论依据,对照养护中的问题,终于探得蕙兰不孕的秘密。2003年秋,江西久旱无雨,气温高达39~44℃的天气持续了约44天。众所周知,蕙兰喜温暖,畏炎热高温。气温20~30℃时生长旺盛,高于30℃则长势缓慢,35℃以上便停止生长。高温长过1周时,管理不善就可能导致死亡。高温天气,兰叶呼吸加剧,尤需通风给氧。蕙兰含氧浓度10~15%,植株的生活吸收机能活跃,生长旺盛;含氧低于5%时,生长受到抑制;低于2%时,新陈代谢机能受到破坏,生活机能全部停滞。前几年所养的
I particularly like orchids. From retirement up to now, cultivation downhill 12 years, experienced several failures, success, how much a little planting experience. May encounter a new problem last fall, and hit “blush bruise ”. Cymbidium 12 pots, a few years ago, every year flowering. The winter of 2003 did not have a bud, though my heart wondered, but still self-comfort, so come see spring. However, the spring and summer of 2004, still the same, flowers disappeared. Forcing me to go back and examine the issues of conservation during the year. At the same time, carefully read the relevant articles of the flower newspaper, to explore the causes of infertility and its theoretical basis, control problems in conservation, and finally explore the secrets of Cymbidium infertility. Autumn 2003, Jiangxi drought drought, temperatures up to 39 ~ 44 ℃ the weather lasted about 44 days. As we all know, Cymbidium hi warm, fear hot and hot. When the temperature is 20 ~ 30 ℃, it grows vigorously. When the temperature is above 30 ℃, the growth is slow, and it will stop growing above 35 ℃. When the high temperature is over a week, poor management can lead to death. Hot weather, Lan Ye breathing intensified, especially ventilation to oxygen. Cymbidium oxygen concentration of 10 to 15%, plant life absorption of active, vigorous growth; oxygen content below 5%, growth was inhibited; less than 2%, the metabolic function can be destroyed, life functions all stagnation.
