摘　　要：文章以人工和天然思茅松桩和段木为寄主的茯苓生长状况,以期更好地了解对茯苓生长状况有影响的因素,从而有针对性地改善人工茯苓生长条件,来提高茯苓产量。实验通过设置4个样地两组对照,每个样地栽培两窖和一株树蔸,每窖设置3根段木,通过引种茯苓,精心培育近1 a,并在采收时记录鲜重,对比天然和人工植苗、坡向、树蔸和段木直径等对茯苓产量的影响。得出结论:(1)同一径阶的树蔸和段木,起源为天然的产量高于人工,但随着径阶的减小,天然和人工产量的差值越大,但当树蔸和段木直径大于20 cm时,起源对产量的影响较小;(2)东南向相较于南向,更适合茯苓生长;(3)径阶相近的段木和树蔸,树蔸的产量远大于段木。This article studies the growth status of Poria cocos using artificial and natural Simao pine stumps and segments as hosts,in order to better understand the factors that affect the growth status of Poria cocos and improve the growth conditions of artificial Poria cocos in a targeted manner to increase Poria cocos yield.The experiment was conducted by setting up four sample plots and two control groups,with each plot cultivating two pits and one tree stump.Each pit was equipped with three segments of wood,and Poria cocos was introduced and carefully cultivated for nearly a year.Fresh weight was recorded during harvesting,and the effects of natural and artificial seedlings,slope orientation,tree stump and segment wood diameter on Poria cocos yield were compared.It was concluded that for the same diameter rank,the yield of natural origin is higher than that of artificial,but with the decrease of diameter rank,the difference between natural and artificial yield is larger,but when the diameter of stump and segment is greater than 20 cm,the influence of origin on yield is less;Compared with the south direction,the southeast direction is more suitable for the growth of Poria cocos;For segment wood and tree stump with similar diameter and rank,the output of tree stump is far greater than that of segment wood.
