Current Situation, Problems And Suggestions Of Crops Straw On Comprehensive Utilization In Xin Zhan Town Of Jiaohe City

Straw is a versatile renewable resource.In recent years,with the annual increase in grain production,the large amount of straw burning in the open air has caused great harm to the environment and violated the concept of green development put forward by the Party Central Committee.This paper compares the“five types” methods of comprehensive utilization of straw in Xinzhan Town(energyization,feedstuff fertilization,raw materialization,base materialization)with the data from Xinzhan Town of Luohe City from 1980 to 2010.Using the literature review method,survey research method,comparative analysis method and other methods,the following results were obtained.1.Comprehensive analysis of the sown area and total output of three main crops of corn,soybeans and rice in Xinzhan Town,Xinzhan Town,Luohe City from1981 to 2010,and the use of chemical fertilizers in Xinzhan Town over the yearsIt turned out that the sown area and yield of these crops are increasing year by year,and accordingly,the straw production also increases year by year.2.Through on-the-spot investigations and surveys and questionnaire surveys,the stalk utilization pattern of Xinzhan Town from 1981 to the present can be summarized and divided into four stages: the full utilization period for heating in1981-1990;the partial replacement period of coal and electricity in 1990-1999;the period of open burning of straw from 1990 to 2010;the period of environmental remediation since 2010.3.According to Jilin Province’s utilization of "five types" of straw and the characteristics of Jilin City’s region,resources,and climate,combined with the constraints of straw utilization policy,technology,capital,and climate of XinzhanTown,the analysis shows that the processing of straw granules(energyization)is a relatively appropriate method of straw utilization in the area.According to the characteristics of a wide cropping area and large straw storage capacity in Xinzhan Town,Luohe City,the comprehensive analysis of the different ways of using straw and the possible environmental impacts comes to a conclusion.It is believed that straw energy production,especially the production of straw pellet fuel,is a more feasible method for the utilization of straw in Xinzhan Town at the present stage,and this passage puts forward three principles of utilization of straw as recycling,adaptation to local conditions and giving prominence to the key points.
