Study On Resource Utilization Potential Of Crop Straws And Livestock In Shouxian

Anhui Province is an agricultural province,Shouxian is a typical agricultural county in Anhui province.there are produce which is a lot of waste of planting and breeding with the development of modernization and urbanization.The waste is crop straw and animal manure.A large number of crop straws were random burning and the animal manure was abandoned or directly pulling into the water without any treatment.It has made a serious environmental pollution and this environmental pollution is one of the important sources of non-point source pollution of agriculture.The crop straw and animal manure had a lot of renewable and clean biomass resources like organic matter and N,P,K.So the resource utilization of planting and breeding waste can not only control the non-point pollution of agriculture,but can saving biomass resources and non-renewable energy.It is an important part of the sustainable development and the development of new socialist countryside.Although there are a lot of study of agricultural resource utilization in other province,but the study involved Shouxian is little.So we survey the total resources of planting and breeding waste and the way of resource utilization,it has a very important meaning of improving the environment,developing ecological agriculture and increase farmers' income.For this,we studied the resources and use patterns in crop straw and animal manure from the year 2010 to 2014,especially the year of 2014.We estimate the amount of resources crop straw and animal manure and analysis of the distribution in the every township to analysis the using potential of resource utilization.The results are as follows:(1)The crop straw in Shouxian is diverse,large amount and has obvious spatial differentiation.The total crop straw resources were 2.0073 million tons in 2014.It main contains rice,wheat,beans,potatoes,cotton and oil seeds.The most are wheat straw and rice straw,they were 0.97 million tons and 0.92 million tons.They accounted for 48.79% and 45.94.According to the distribution,Anfeng town is the maximum in the crop straw.It reach to 0.13 million tons and accounted for7.25%.Followed by is Xiaodian town and Yanliu town,they are both higher than 0.12 million tons.This area had large use potential in the future in the use of crop straw.(2)The animal manure in Shouxian is diverse,large amount and has obvious spatial differentiation.The total animal manure resources were 2.0409 million tons in2014.It main contains pigs,sheep,poultry,etc.Among them,the animal manure ofpigs is the main source of animal manure in Shouxian,it was 0.114 million tons and it accounted for 55.96%.Followed by is poultry,it only 0.52 million tons.According to the distribution,Yanliu town is the maximum in the animal manure,it has 0.1631 million tons and accounted for 8.07%.The animal manure resources of Yinhe town is0.16 million tons.This area had large use potential in the future in the use of animal manure.(3)The planting and breeding waste in Shouxian is huge and has obvious spatial differentiation.The planting and breeding resources in Shouxian were 4.04 million tons.According to the distribution,Yanliu town is the maximum above all the towns.The planting and breeding resources were 0.03 million tons and it accounted for7.07%.The crop straw resources and animal manure resources are approximately equal and the animal manure resources is slightly higher than crop straw resources.So animal manure will become the main part of resource utilization of planting and breeding waste in every town.(4)Shouxian had a huge potential in the resource utilization of planting and breeding waste.If take the planting and breeding waste in 2014 into fertilizer,it can bring organic matter 1.85 million tons,nitrogen 2.16 thousand tons,phosphorus 1.34 thousand tons and potassium 2.04 thousand tons.According to the distribution of planting and breeding waste,the maximum organic matter resources(0.11 million tons)were in Anfeng town.According to potassium,Anfeng town(1.24 thousand tons),Yanliu town(1.00 thousand tons)and Sanjue town(1.20 thousand tons)were rich.If take the planting and breeding waste into energy.It can bring coal 0.80 million tons and biogas 0.43 million cubic meters.Among them,rice and wheat as the two main crops,they had the maximum potential in energy.Respectively is 0.34 million tons and 0.42 million tons in coal,0.16 million cubic meters and 0.25 million cubic meters in biogas.Besides,the potential also reflected in the animal feed and raw materials of edible fungi.In this study,through literature review and field survey we find out the amount of resources of planting and breeding waste and utilization status.Then analyzed the existing problems.It had an important theoretical and practical significance to give the suggestion to Shouxian even Anhui province to solve the problem of planting and breeding waste.
