Taking "production in a large amount, consumption in a large amount, a largeamount of discard" as traditional agricultural economy defect of development patternof characteristic, causes resource waste, destroy and not in short supply. Theenvironment dissolving self-purification ability with difficulty to support and constantdeterioration of environmental quality, is seriously restricting the agriculturalsustainable development. The agricultural circular economy is for the purpose ofconstructing agricultural economy system of " resources -production -waste -revivalresources" and is one new economic form of adapting the optimized agricultureindustrial structure, the resources utility reasonably, the ecological environmentprotection, the agriculture sustainable development advancement. This articleanalyzes poultry development swiftly in Shandong Province, small developing scale,low poultry excrement proposal ratio, serious pollution, as well as amount of the cropsstraw and low utilization. Taking Baita town of the agriculture, the poultry, the forestas pillar industry as an example, comes out the barrier factor of developing circulareconomy analyzing agricultural economy present situation and explores technical wayof the poultry excrement and the straw. Its goal is to establish the agricultural circulareconomy pattern. It has very important practical significance to solve environmentpollution,resource waste and agricultural sustainable development.This article profits from ecology, economy, statistics, and discovers the circulareconomy barrier factor of Baita town, through the qualitative analysis and thequantitative investigation. Exerting agriculture, fertilizer and engineering science,comes out technology methodology of the poultry excrement and straw. Takingcircular economy theory and scheming science as the foundation, this article proposesquantitative pattern of agricultural circular economy. Through analyzing societybenefits,economy benefits and environment benefits, evaluating quantitatively effectof agricultural circular economy pattern.The research indicated:1 The agricultural circular economy in Baita town developed forward graduallyfrom 1996 to 2005, and the agricultural circular economy synthesis index in 2005 was1.497 times in 1996. The main barrier factor was in turn the straw synthesis utilitycoefficient, poultry excrement resource rate, agriculture commodity rate, GDP outputvalue of the unit agriculture, the agricultural hypothesized water coefficient, theeffective irrigation coefficient, the average farming, the average grain yield, thepesticide utility level. The main barrier factor in 2005 concentrated in the resourcescircular utility.2 Sweet potato straw composting was better compared to other straw slightly, butwas better compared to pure cow excrement composting. The effect of IV cowexcrement: sweet potato straw = 2: 1 is the best, and is the best allocated proportionwhich this experiment obtained. It may use for an important technical measure inBaita town.3 The agricultural circular economy of Baita town should construct "the levelstructure pattern" of the farmer, the village, the town. Looking from the entire town,the current poultry cultivation scale is insufficient to satisfy the agriculture and the lifedemand in Baita town, and the partial fertilizers must depend on the chemicalfertilizer, the partial families energy must depend on the electricity and the fuel. In theland utilization way and the population invariable situation, Baita town poultry scalemust enhance to 2.5 times to satisfy the agriculture and the life demand in Baita town.In summary, the main barrier factor of agricultural circular economy in Baitatown is resources circular utility. It's the recent destination to improve circulationutility of sweet potato straw and cow excrement. The effect of IV cow excrement:sweet potato straw = 2: 1 is the best, and is the best allocated proportion which thisexperiment obtained. It may use for an important technical measure in Baita town."The level structure pattern" of the farmer, the village, the town may obtain very goodeconomy, environment and social efficiency.
