The invention discloses a method for no-tillage crop rotation of flue-cured tobaccos and pastures. The method uses excellent gramineous pasture pennisetum hydridum and flue-cured tobacco for no-tillage crop rotation and comprises the detailed steps of: ridging during the first year when planting flue-cured tobaccos, and leaving the tobacco sticks on the tobacco ground to protect the ridge body after harvesting the tobacco leaves; clearing up the tobacco sticks and weeds after spring comes in the second year, then planting the pennisetum hydridum of which the planting density is the same as the planting density of the flue-cured tobacco, and leaving the residues of the pennisetum hydridum in the ridge body after harvesting the pennisetum hydridum completely, and protecting the ridge body; using phytocide to control the growth of the weeds after spring comes and before the tobacco is planted in the third year, digging the ridge when planting tobaccos, fertilizing, and planting tobaccos; clearing up the ridge surface, removing the weeds, covering the ground by a ground membrane when the soil moisture content is enough so as to promote normal growth of the flue-cured tobacco, and repeatedly performing alternant planting of flue-cured tobacco -> pennisetum hydridum -> flue-cured tobacco in this way. The method has the advantages of: increasing the crop rotation efficiency of the flue-cured tobacco, increasing the quality of the tobacco leaves, saving the steps of turning over of the soil, ridging, topdressing, intertillage, weeding and the like, saving six workers every 667 square meters of flue-cured tobacco, reducing the production cost, and being simple to operate and easy to popularize.

The invention pertains to the field of the comprehensive utilization of pennisetum hydridum resources and relates to a method for the staged transformation and poly-generation of pennisetum hydridum, wherein after the steam explosion, the pennisetum hydridum is washed with water and water lotion is degraded hemicellulose used for preparing Xyol-Oligosaccharides; and then staged carding is carried out to the pennisetum hydridum after the steam exploded treatment to obtain long fiber (the fiber length is more than 3cm) and short fiber (the fiber length is less than 3cm). The long fiber after the carding is used for the auto-catalytic pulping of alcohol to obtain pennisetum hydridum pulp and alcohol soluble lignin. The short fiber after the carding is used for the solid-state fermentation of cellulase and then for synchronous saccharification and fermentation of alcohol, and fermentation residues generated in fermentation are used for biomass power generation and CO2 generated in the fermentation is reclaimed. The fermentation residues for biomass power generation, the pennisetum hydridum pulp, the alcohol soluble lignin, Xyol-Oligosaccharides and CO2 generated in the fermentation are cogenerated in the whole technological process of the fermentation of fuel alcohol with the pennisetum hydridum so as to realize the highly efficient comprehensive utilization of pennisetum hydridum resources.

The invention discloses a Pennisetum hybrid planting method and a method for jointly producing marsh gas by using Pennisetum hybrid as a raw material. The planting method comprises the steps of: preparing a land: deeply plowing soil in winter, harrowing and ridging in March, keeping ridge width to be 4m, opening field ditches and transplanting the Pennisetum hybrid in the middle and last ten days of April; reasonably and densely planting: keeping the row spacing and the plant spacing of the Pennisetum hybrid to be respectively 120cm and 60cm, keeping the density to be 13889 plants / hm<2>, sowing seed roots, cutting the seed roots into sections with 2-3 nodes per each section, flatly burying the sections into the soil, covering the sections with the soil and conducting general management; and harvesting: using a machine for harvesting, leaving stubbles with depth being 10-15cm, setting cutting frequency to be once per three months and harvesting 3-4 times per year. By using the planting method to plant the Pennisetum hybrid and by controlling the production conditions, the growth time and the cutting frequency, the biomass per mu of the Pennisetum hybrid can be enabled to reach a higher level; and by using the obtained Pennisetum hybrid to produce the marsh gas, the cumulative gas output per mu can be enabled to reach a higher level and the coupling of the gas output and the biomass per mu of the raw material is enabled to reach an ideal state.
