Become, the ratio of rural households' selection commercial energy is being continuously improved, and the quantity that agricultural crop straw is used as the energy is constantly declined, quotient
The product energy (such as coal, liquefied gas) has become main cooking energy.To biomass straw, weeds feed is raised by commodity for cultivation institute
Material substitution, biomass organic fertilizer needed for agricultural production are substituted by inorganic fertilizer, stalk used in life of farmers and agricultural production
Sharply decline.Meanwhile agricultural crop straw yield rapidly increases with crops, the especially increase of cereal crops yield.Farming
Drug on the market that stalk is caused to be abandoned in field, house courtyard for object stalk, or even is directly burned in field.It abandons in room
Room courtyard and the stalk in field will affect environment and cause fire, lead to pollution of waterhead.Air can be polluted in open incineration stalk,
People's health is endangered, especially traffic safety is will affect in airport, near Highway burning, causes aircraft to ground, highway automobile
It knocks into the back collision, the adverse consequences such as shade tree is burned out.Currently, although various regions government has all put into effect the method for forbidding Open Burning Crop Residue
Rule, but open incineration agricultural crop straw still remains incessant after repeated prohibition, environment causes seriously to pollute, and causes tremendous economic to damage to society
It loses.
While the biomass resources such as stalk are wasted, combustion gas used in China's industrial and agricultural production, fuel oil, thermal energy,
The current main fossil energy such as coal, petroleum is increasingly reduced, and there is a serious shortage of energy crisis has become social development
Bottleneck problem is problem in the urgent need to address at present.
With the rapid development of society, people constantly seek energy-saving and emission-reduction and the increasingly increased attention of ecological environmental protection
It asks using the new energy, control atmosphere pollution, energy-saving and emission-reduction, reduces greenhouse effects.It is raw with agricultural crop straw, excrement, chaff slag etc.
The technology that physical obsolescence resource comprehensive is converted into available resources has caused the highest attention of departments at different levels of government.
