马尾松幼林袋料套种茯苓效果初报

Preliminary report on the effect of bag material interplanting of Poria cocos in young Pinus massoniana plantation

本文将茯苓袋料栽培应用于马尾松幼林地套种,以期达到茯苓丰产和马尾松幼林生长加快的双重效果。结果表明:在马尾松2年生和3年生幼林中套种茯苓,单个菌袋平均鲜茯苓产量高于旱地种植产量,在种植密度11 250袋·hm^-2情况下,鲜茯苓产量达到33 694 kg·hm^-2;套种茯苓的3年生马尾松幼林,植株高、地径生长分别比对照增加15.9%和60.8%。

In this study, bag material interplanting of Poria cocos was applied in young Pinus massoniana plantation double effects of high yield of Poria cocos and faster growth of young Pinus massoniana plantation.The results showed to gain that mean yield of fresh Poria cocos in each fungi bag after interplanting in 2 a and 3 a young Pinus massoniana plantation was higher than that in dry land.The yield of fresh Poria cocos climbed up to 33 694 kg · hm^ -2 with the planting density of 11 250 bag · hm^ -2 .Tree height and DBH growth increased 15.9% and 60.8% from control in 3 a Pinus massoniana plantation interplanted with Poria cocos , respectively.
