摘　　要：结合红锥实生苗繁育生产实践,在归纳红锥的种子采集、处理、储藏、播种、施肥等技术措施的基础上,对种子出芽率、苗木保存率、苗高、地径等生长情况进行观测、调查分析,发现红锥苗木苗高、地径生长均呈现“慢-快-慢”的规律,分析出红锥苗木生长的初期、高峰期和后期,以及相应苗期管护措施,为红锥实生苗繁育工作提供一定的理论依据和技术参考。Combining with the breeding and production practice of Castanopsis hystix seedlings,on the basis of summarizing the technical measures of seed collection,treatment,storage,sowing,fertilization and so on,observation,investigation and analysis were carried out on the growth conditions of the seedlings,such as sprout rate,preservation rate,seedling height and ground diameter,etc.,and it was learned that the growth law of the seedling height and ground diameter of Castanopsis hystix seedlings showed"slow-fast-slow".The early,peak and late growth of Castanopsis hystix seedlings were analyzed,as well as the corresponding seedling management measures,which would provide a certain theoretical basis and technical reference for Castanopsis hystix seedling breeding.
