杉木油桐仙人草复合经营模式生物量的研究

A Study on the Biomass of Cunninghamia lanceolata, Aleurites fordii, Mesora chinensis Compound Pattern

杉木、油桐、仙人草复合经营模式５年生生物量及其分布的研究结果表明：复合模式地上部分和根系生物量分别为５３．２１６ｔ／ｈｍ２和１２．３６９ｔ／ｈｍ２，分别是对照的１．０９倍和１．２０倍；复合模式中杉木平均树高、胸径和单株生物量分别是相应对照的１．１１倍、１．０７和１．０２倍，细根量则是对照的１．４２倍；复合模式生物量地上和地下部分的分布均比相应对照趋向合理，这对提高光能和土地利用率有利．

The biomass and its distribution on compound patterns of Cunninghamia lanceolata, Aleurites'fordii, Mesora chinensis and control in 5 years old were studied in 1991. The result showed, the biomass on the ground and the root system in compound pattern were 53.216t/hm2 and 12. 369t/hm2, seperately. The average height, diameter, indivial tree biomass and the amound of fine root of Chinese fir in compound pattern were 1. 11 times, 1. 07 times, 1. 02 times as much as that of control. In contrast to the control, the biomassdistribution above and under ground in compound pattern are reasonable, it can raise the utilization ratio of the soil and the solar energy.
