BioEnergy is an archetypal appropriate technology
\r\nand alternate source of energy in rural areas of China, and can meet
\r\nthe basic need for cooking fuel in rural areas. The paper introduces
\r\nwith an alternate mean of research that can accelerate the biogas
\r\nenergy production. Tithonia diversifolia or the Tree marigold can be
\r\nhailed as mesophillic anaerobic digestion to increase the production
\r\nof more Bioenergy. Tithonia diversifolia is very native to Mexico and
\r\nCentral America, which can be served as ornamental plants- green
\r\nmanure and can prevent soil erosion. Tithonia diversifolia is widely
\r\ngrown and known to Asia, Africa, America and Australia as well.
\r\nNowadays, Considering China’s geographical condition it is found
\r\nthat Tithonia diversifolia is widely growing plant in the many tropical
\r\nand subtropical regions of southern Yunnan- which can have great
\r\nusage in accelerating and increasing the Bioenergy production
\r\ntechnology. The paper discussed aiming at proving possibility that
\r\nTithonia diversifolia can be applied in biogas fermentation and its
\r\nbiogas production potential, the research carried experiment on
\r\nTithonia diversifolia biogas fermentation under the mesophilic
\r\ncondition (35 Celsius Degree). The result revealed that Tithonia
\r\ndiversifolia can be used as biogas fermentative material, and 6%
\r\nconcentration can get the best biogas production, with the TS biogas
\r\nproduction rate 656mL\/g and VS biogas production rate 801mL\/g. It
\r\nis well addressed that Tithonia diversifolia grows wildly in 53
\r\nCounties and 9 cities of Yunnan Province, which mainly grows in
\r\nform of the road side plants, the edge of the field, countryside, forest
\r\nedge, open space; of which demersum-natures can form dense
\r\nmonospecific beds -causing serious harm to agricultural production
\r\nlandforms threatening the ecological system as a potentially harmful
\r\nexotic plant. There are also found the three types of invasive daisy
\r\nalien plants -Eupatorium adenophorum, Eupatorium Odorata and
\r\nTithonia diversifolia in Yunnan Province of China-among them the
\r\nTithonia diversifolia is responsible for causing serious harm to
\r\nagricultural production. In this paper we have designed the
\r\nexperimental explanation of Biogas energy production that requires
\r\nanaerobic environment and some microbes; Tithonia diversifolia
\r\nplant has been taken into consideration while carrying experiments
\r\nand with successful resulting of generating more BioEnergy
\r\nemphasizing on the practical applications of Tithonia diversifolia.
\r\nThis paper aims at- to find a new mechanism to provide a more
\r\nscientific basis for the development of this plant herbicides in Biogas
\r\nenergy and to improve the utilization throughout the world as well.<\/p>\r\n","references":"
