Abstract
The invention discloses a method for planting puelia and producing biogas by puelia as biomass energy, which belongs to a plant cultivation technology of biomass energy and an application thereof. The invention provides a scientific cultivation method with high yield and easy control, in particular a method for producing biogas by harvested puelia cultivated by scientific approaches of selecting, taking and cultivating seeds, planting, and the like. The puelia planted for 8 months-12 months is used for producing the biogas, and the fresh puelia per ton can produce the biogas of 440 m<3>, wherein the biogas contains 60 percent of methane, and the biogas production rate is 440 m<3>/t*TS. The new puelia seed provided with the invention is a novel puelia seed and is a novel raw material for producing biogas; and the cultivating method of the puelia is simple and easy to learn. The fresh puelia per mu per year can reach 35 tons at maximum by the cultivation method, and the biogas producing amount is high.

Show from the retrieval of the interrelated data that comprises Chinese patent, do not see the huge bacterium grass of plantation is produced biogas as biomass energy relevant report at present both at home and abroad as yet.
Summary of the invention
The objective of the invention is to provide a kind of output height, and support the science of holding easily and cultivate huge bacterium grass method, and produce the method for biogas with huge bacterium grass as biomass energy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of planting huge fungous grass is characterized in that:
1) seed selection: the stem of selecting the huge bacterium grass of growth more than 6 months is as grass seeds;
2) presoaking and germinating: 0.5～1.5 meter length of grass seeds intercept, the back promotes the growth of its root and bud with the N element solution soaking grass seeds of trace 2 ‰;
3) plantation: dig the plantation ditch earlier, wide 20 centimetres, dark 20～30 centimetres, the line space between the ditch is 60 centimetres; The plant headtotail that intercepting is long 0.5～1.5 meter is emitted in the plantation ditch, and earth backing 2～3cm, compacting are promptly watered after the plantation; Begin fertilising behind 20 centimetres of the heights of seedling.
4) harvesting: use mechanical harvesting, keep root, wherein 8 weeks of high temperature season gather in once, and low temperature season 12 week harvesting once.
Described presoaking and germinating, the height of its root and bud are 1～3 centimetre.
The described cold district that is planted in adopts the method grow seedlings earlier and afterwards plant, and the cane of a joint of clip broken or seedbed is grown seedlings about 20 centimeters transplanting of height of seedling with nutrition.
The present invention uses the method that huge bacterium grass is produced biogas:
Plant 8～12 months huge bacterium grass, be used to produce biogas, bright grass per ton can produce 440 cubic metres of biogas, wherein contains 60% methane, and factor of created gase is 440m
3/ tTS.
Huge bacterium grass is produced the technology of biogas as biomass energy:
1, the once huge bacterium grass of the per 8 weeks harvesting of high temperature season, the once huge bacterium grass of the per 12 weeks harvesting of low temperature season is as the raw material of producing biogas;
2, the preliminary treatment of the huge bacterium grass of harvested raw material: the water content of controlling huge bacterium grass is 75%, and bright grass meal is broken into the grass meal of 3mm, pulverizes making beating, TS (dry substance concentration) concentration to 8%～10% again.
3, the C/N ratio of control step 2 material is 27: 1～30: 1, pH value=6.8～7.5
4, inoculation: add at 1: 1 according to dry matter, the employing sludge of sewage treatment plants is an inoculum, and slurry carries out anaerobic digestion under 35 ℃ of medium temperature conditions in reactor.
The invention has the beneficial effects as follows: the grass seeds of the present invention's plantation is a new grass seeds, is a kind of new production biogas raw material, and huge bacterium grass cultivation method is easy to learn, and with method cultivation of the present invention, the highest every mu of bright grass of annual output can reach 35 tons, and produces biogas amount height.
