须弥红豆杉幼树林农林复合经营的初步研究

为了解决须弥红豆杉幼树林无收入、抚育成本高的问题，进行了不同的间作模式试验研究，结果表明：效果较好的间作模式为“红豆杉-蚕豆-大豆”，能获得较大效益，间作植物的红豆杉幼林的树高生长高于未间作，且差异显著，依次为：红豆杉-蚕豆-大豆＞红豆杉-蚕豆-不间作＞红豆杉-不间作-大豆＞未间作；而地径则小于未间作，对当年生最长枝及发新梢树无明显差异，须弥红豆杉幼树林进行豆类（大豆、蚕豆）间作经营是一种较为理想的复合经营模式，可在适宜的区域进行推广。

A Preliminary Study on Compound Management of Agriculture and Forestry of Taxus Wallichiana Sapling Forest

In order to solve the“no income”problem of Taxus wallichiana＇s sapling forest and the high raising cost issue ,several different intercropping model tests are conducted .The intercropping model with better effect is “T .wallichiana - broad beans -soybean” ,which can get the maximum benefit .The intercropping trees in the Taxus chinensis sapling forest are higher than the non -intercropping ,and the difference can not be neglected ,which follows the sequence ：“T .wallichiana - broad beans -soybean” 〉 “T .wallichiana -broad beans -non-intercropping tree” 〉“T .wallichiana -non-intercropping -soybean” 〉“non -inter-cropping”;However ,the ground diameter of intercropping is less than the non -intercropping ,and there＇s no obvious difference in the year＇s longest tree branch and new sprout＇s tree .T herefore the intercropping of T . wallichiana sapling forest with beans （soybean ,broad bean） is an ideal compound management model ,which can be popularized in suitable areas .
