台江采育场竹木混交林丰产措施试验

对台江林业采育场现有竹木混交林进行施肥和土壤垦复两种试验，结果表明，不同施肥处理虽有一定增产效果，但经方差分析未达到显著水平；不同土壤垦复措施的增产效果，以深翻加施肥的新竹产量最高，锄草松土居第二，单纯深翻并不理想，效果不如劈山抚育。因而，新兴竹木混交林应以调整竹林结构和护笋养竹为主，每年锄草松土即可达到材用丰产林标准，不宜盲目深翻、施肥。

Experiments on High-Yield Measures of the Mixed Forest of Bamboos and Trees on Taijiang Felling and Cultural Farm

Two experiments on applying fertilizers and reclaiming soll have been made in the current mixedforest of bamboos and trees on Taijiang Felling and Cultural Farm. The results show that（1）adjustingbamboo forest structure and protecting bamboo shoots to culture bamboos should be mainly conducted fornew mixed fOrests of bamboos and trees;（2）eradicating weeds and lossening soil each year can make newmixed forests of bamboos and trees reach high－yield forest standards for timber；and（3）it is not proper tounrealistically perform deep tillage and fertilization for new mixed forests of bamboos and trees.
