Comprehensive Benefit Analysis Of Main Utilization Mode Of Corn Straw In Jilin Province

Ji Jilin Province is the main grain production area(in China)and the main commodity grain base,known as the gold corn belt,it is rich in corn straw resource.At present,there are still farmers in Jilin Province illegally burning and discarding straw and wasting resources at the same time,causing environmental damage.The research on the will of farmers to return straw can promote the use of straw return technology,sustainable development of agriculture and rural social economy,and achieve the overall goal of ensuring the warmth of farmers' homes and clean environment in Jilin Province.On the basis of studying and grasping the theory of circular agriculture economy,cost-benefit theory and farmer's behavior theory,this paper calculates the theoretical resource quantity,collectable resource quantity and available resource quantity of corn straw in Jilin province from 2010 to 2019 by using the grass-valley ratio method.Through the construction of a two logistic regression model,the effect of farmer's characteristic,operation mode,cognitive behavior of farms and the external environment on adopting straw returning will was analyzed.Find out the plight of the technology of returning corn straw to the field in Jilin Province,and put forward some countermeasures and suggestions.The following conclusions are drawn through the research: the quantity of straw resources in Jilin Province is increasing year by year.At present,the main formation of the full coverage of corn straw wide and narrow row less no-tillage cultivation technology,straw "enrichment deep" return to the field technology,straw full volume of crushing deep turn back to the field-based return technology,straw return technology has a broad prospect,but there are still some problems,such as support policy has not formed a strong grasp,technology immature,propaganda and technical guidance coverage area is not wide.The empirical results show that the main factors influencing farmers' willingness to adopt straw return are: education level,whether they have participated in the training of straw returning,corn planting area and obtaining large scale.The difficulty degree of straw processing a machine,corn planting area,whether to set up a family farm or join a planting cooperative,whether to send straw back to the field subsidy in a township,whether to know the technology of return straw to the field,and how the farmer thinks the difficulty degree of returning straw to the field.Among them,the proportion of non-agricultural income to household income has a negative effect on a farmers' willingness to adopt straw to return to the field,and the other factors have a positive effect.Sex,age,annual household income,number of of people in the househol,investigation and punishment of straw burning,publicity of straw returning to the field,whether farmers know the relationship between straw returning to the field and farmland environmental protection,whether they know the relationship between straw returning to the field and soil fertility,and whether they know the straw returning to the field the relationship between returning farmland and crop yield had no significant effect.Based on the analysis of logistic binary regression model,some suggestions are put forward.The first is to deepen the reform and improve the incentive policy for straw returning to the field;the second is to strengthen supervision to ensure that subsidies are in place;the third is to innovate the technology of straw returning to the field and actively research and development of relevant agricultural machinery for corn straw returning to the field;the fourth is to increase publicity and expand the scope of technical pilot projects;the fifth is to vigorously develop new agricultural operators;and the sixth is to establish a service system for returning straw to the field and strengthen technical guidance.
