摘要： Mixtures of grass and clover can be productive and sustainable for industrial and energy purposes. However, not all parts of the biomass are suitable as industrial substrate and there is a need for methods to separate fibrous parts from other biomass.Biomass production was evaluated in two-cut systems at two sites on marginal land. One site is Alnarp in Lomma, southern Sweden on a former pasture on coarse soil. The other is Robacksdalen in Umea, northern Sweden on agricultural silty soil with poor drainage. Reed canary grass Phalaris arundinacea L. (2 varieties) and tall fescue, Festuca arundinacea Schreb. were sown, either in monocultures, or with clovers, in a randomized design. In addition, we sowed four mixtures in larger plots on another fieldto make round bale silage for drying and fractionation experiments using a cyclone process. Reed canary grass was very competitive and outcompeted tall fescue and clover where it thrived. However, at Alnarp tall fescue dominated in parts of the plots where the soil was too dry for reed canary grass. We present production data from two to three growing seasons along with evaluation of the cyclone process.
