| Corn is one of the important crops in China,among which corn stalks,as a renewable resource,are also produced in large quantities every year.Corn stalks are rich in a large number of chemical nutrients.If they are discarded after the corn is picked,it will cause a serious waste of straw resources.The utilization of straw resources is an important way for our country to realize sustainable development and green agriculture,and at the same time it has greatly helped the increase of farmers’ income and the improvement of rural environment.This research conducted an in-depth analysis of the problems in the utilization of corn stalks in my country,actively explored the utilization mode of corn stalks in my country,analyzed its cost and benefit,and put forward reasonable suggestions to guide different subjects to better utilize corn stalk resources..In this study,firstly,through literature review and data collection,the relevant data of farmers’ straw returning to the field and the production and operation data of straw utilization enterprises in the new era were obtained.On this basis,the quantity,distribution and resource utilization mode of corn stalk resources in my country were comprehensively and thoroughly investigated.analysis.Secondly,through field visits,household surveys,and experimental testing,a thorough understanding of corn stalks returning to the field and feed utilization.Through analysis of related issues,it is found that the development of a new utilization model based on returning corn stalks to the field can make the straw resources more fully utilized.In order to further evaluate the effect of corn stalk resource utilization,this study used cost analysis,carbon emission reduction,stalk energy conversion rate,industrial development capacity and resource substitution benefits to return corn stalks to fields,feed,and use for power generation and power generation.Calculate the economic,ecological and social benefits brought by bio-energy production.Finally,according to the results of the calculation,a discussion was carried out on the cost-benefit,social and ecological benefits of the utilization of corn stalks,and reasonable suggestions and corresponding strategies were put forward for the further development of the utilization of straws in my country.Studies have shown that the cost of returning corn stalks to the field is not only lower,but under the same circumstances,the benefits are significantly higher than those of crushing and returning to the field.There is no significant difference in the production cost of corn stalk silage and ammoniated feed,but the income of silage belt in the development of animal husbandry is significantly higher than that of ammoniated feed.Through the investigation of the corn stalk power generation project of Guoneng Wangkui Biological Company,it is found that the efficiency of corn stalk power generation through biomass direct-fired boilers is significantly better than that of biogas power generation.The reduction of emissions plays an important role.At the same time,the benefits of using corn stalks as a base material to produce sugar alcohols are also extremely impressive.Therefore,based on the above results,this paper proposes that on the existing basis,we should further strengthen the rational formulation of straw returning to the field,improve the technology and agricultural use of the field,and promote the industrialization of straw utilization.Then,with the support of policies,continue to improve the construction of supporting facilities,establish an efficient straw collection,storage and transportation system,and form a pattern of complementary advantages and multiple recycling uses of corn stalks. |
