摘　　要：在2年龄艾园母桩与幼桩共生下,对两者关系进行4种处理,结果表明:切断根系联系会使生产力降低,分别去掉母桩或幼桩,主桩的生产力大于幼桩。基础密度和根系受损程度是主要影响因素。以常规的母桩与幼桩保持根系联系,产量最高。The mother and young piles under the symbiosis conditions of mother and young piles of Blumea balsamifera were tested to investigate effects of artificial interference on the productivity of mother, main and young piles. The results show that the cutting the linkage of root system between mother and young piles greatly decreases their productivity and the productivity of the main pile is better than that of young pile when removing the mother pile or young pile. The main factors of affecting the pile productivity are the basic population and damage degree of the root system. The yield is up to the maximum when keeping the linkage of root system between mother and young piles.
