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 results of five-year biomass and its distribution in the fir, tung tree and immortality showed that the above-ground biomass and root biomass in the composite model were 53.216t / hm2 and 12.369t / hm2, respectively. 09 times and 1.20 times respectively. The mean tree height, DBH and single plant biomass in the composite model were 1.11 times, 1.07 and 1.02 times that of the corresponding control, respectively. 42 times. The distribution of aboveground and underground parts of composite model biomass is more reasonable than the corresponding control, which is beneficial to improve the light energy and land utilization.
