林下种植万寿菊可以充分利用林下空间,提高林地资源利用率。本试验通过对不同郁闭度下万寿菊的生物量、产量和品质的测定,对比分析了各处理的株高、单株花朵数、花径、单花质量、总产量以及叶黄素含量。结果表明:17%的低郁闭度及45%的中郁闭度情况下万寿菊单花质量极显著高于69%高郁闭度;花总产量随着郁闭度增大而降低;低郁闭度下叶黄素产量为13.35 kg/667 m~2,明显高于中郁闭度的9.29 kg/667 m~2和高郁闭度的2.13 kg/667 m~2。
Planting marigold under the forest can make full use of space under the forest to improve the utilization of forest resources. In this study, the plant height, number of flowers per plant, flower diameter, single flower mass, total yield and lutein content were compared by measuring the biomass, yield and quality of marigold under different canopy density. The results showed that the flower quality of marigold flower was significantly higher than that of 69% under the condition of 17% low canopy density and 45% middle canopy density. The total flower yield decreased with the increase of canopy density Under the canopy closure, the lutein yield was 13.35 kg / 667 m ~ 2, which was significantly higher than that of the middle canopy density of 9.29 kg / 667 m ~ 2 and the high canopy density of 2.13 kg / 667 m ~ 2.
