摘要
为研究狼爪瓦松(Orostachys cartilaginous A.Bor)的生物学特性,掌握其生长规律,对吉林省龙井市郊的瓦松生长地进行了定位、定期观察。论述其生物学特性,补充并明确了其形态特征、生长发育特征,其繁殖以分蘖繁殖为主;瓦松在向阳石质山坡生长良好,耐旱性特别强,周围几乎没有伴生植物;瓦松生长地土壤有机碳、碱解氮、速效磷、全磷、速效钾、全钾的含量都极低,属于贫瘠土壤;室内驯化试验表明,瓦松在含有机肥与沙子各一半的基质中生长良好。
The positioning and routine observation for Orostachys cartilaginous in suburban Longjing of Jilin Province were carried out to study the biological characteristics and growth regularity of Orostachys cartilaginous with the supplementary illustration on the morphological and growth characteristics.Orostachys cartilaginous was tillering reproduction and grew well on the sunny stone slope without associated plants on account of its strong drought resistance.The soil of Orostachys cartilaginous growing place was poor and its contents of organic carbon,effective nitrogen,rapid available phosphorus,total phosphorus,rapidly available potassium and total potassium were low.The indoor domestication test showed that Orostachys cartilaginous grew well in the matrix containing half of the organic fertilizer and half of the sand.
