NOVELTY - An ecological cycle maize straw utilization system comprises a maize planting base, a maize straw treatment equipment, an alcohol factory, an animal farm, a solid fuel and mash gas generating device, an earthworm breeding field and an organic food base. The maize straw is obtained from maize planting base, crushed by the treatment equipment, and pressed to produce solid fuel or provided to the alcohol factory. It is used for fermenting and producing low concentration alcohol by adding yeast to obtain raw material of ethanol fuel, and obtain straw vinasse.    USE - An ecological cycle utilization system for maize straw.    ADVANTAGE - The system forms an ecological agriculture recycling economy industrial chain to realize the zero discharging of maize straw and makes the industrialized production of alcohol fuel from maize straw possible. It greatly improves the revenue of the enterprises and the farmers and produces energy which is needed urgently by the country.    DETAILED DESCRIPTION - An ecological cycle maize straw utilization system comprises a maize planting base, a maize straw treatment equipment, an alcohol factory, an animal farm, a solid fuel and mash gas generating device, an earthworm breeding field and an organic food base. The maize straw is obtained from maize planting base, crushed by the treatment equipment, and pressed to produce solid fuel or provided to the alcohol factory. It is used for fermenting and producing low concentration alcohol by adding yeast to obtain raw material of ethanol fuel, and obtain straw vinasse. The straw vinasse is provided to animal farm to feed the animals. The mash gas obtained from fermenting excrement of the animals is provided to alcohol factory to produce alcohol fuel to provide clean gas fuel to human. The fermented excrement is used for feeding earthworm and the earthworm is taken to be the fine fodder of chicken, duck and fish. Meat, eggs and fish are also produced as organic food. The excrement of earthworm is returned back to the farmland to improve the fertilization of the land to increase the output of the maize and form a good ecological cycle utilization system to realize the sustainable development. An INDEPENDENT CLAIM is included for technical flow of ecological cycle maize straw utilization system.    DESCRIPTION OF DRAWING(S) - The drawing is a flow diagram of the ecological cycle maize straw utilization system (Drawing includes non-English language text).
