Analysis On Economic Benefit And Ecological Benefit Of Different Planting Structure In Minqin County

In recent years,countries and governments at all levels attach great importance to the important role of agricultural structural adjustment on economic benefits and ecological and environmental protection.Minqin County,Gansu Province is a typical oasis irrigated agricultural area and inland desert area,as the northwest region important commodity grain base and economic crop concentration area,its economic strategic position is very important;the same time,Minqin County as the northwest region and the whole country Of the important green barrier,long-term drought and water,sand invasion,serious desertification,ecological and environmental problems,making the local economic and social problems,agricultural development has been seriously hampered.Therefore,through the empirical study on the agricultural structure of Minqin County,which is fragile in ecological environment,it not only has important research value for the local agricultural development and ecological protection,but also has important reference value for China agricultural development.In this paper,three typical townships,such as Suwu Township,Hongsha Liangxiang Town and Donghu Town,were selected by stratified random sampling according to the traditional agricultural planting pattern,grain dual planting pattern and grain feeding and feeding mode.Farmers’ surveys and soil collection tests.And then analyzes the economic benefits,ecological evaluation and organization form of different agricultural planting modes,and finds out the rationality and feasibility of the agricultural structure adjustment in Minqin County.It is suggested that Minqin County should develop the economic and ecological benefits Grassland agriculture,the establishment of structural adjustment of the farmer cooperative organization form,promote the grass industry and animal husbandry industry linkage development,from the farmer,the government and the farmer cooperatives three main body put forward the corresponding countermeasure suggestion.The main conclusions of this paper are as follows:1.From the perspective of economic efficiency,the differences in input,output and income of farmers in different agricultural cropping patterns are obvious.Theresults showed that the output of farmer was from 27213 yuan/hm~2,17783 yuan/hm~2 and 17223 yuan/hm~2 of the traditional grain cultivation mode,and the cost of farmer was the highest The traditional grain cultivation mode is 10099 yuan/hm~2,and the grain cultivation mode is 7836 yuan/hm~2.From the income of different agricultural planting mode,the high-to-high-The yield is high and low from the yield of different agricultural cropping patterns.The yield of the grain is higher than that of the other agricultural cropping patterns.The yield is high,The yield of the three patterns was127%,101% and 71%,respectively,for the grain cultivation mode,the grain cultivation mode and the traditional grain planting pattern.2.From the perspective of ecological evaluation,the soil organic carbon(SOC)was 9.94g/kg,and the soil was cultivated by the binary cropping pattern.The soil organic carbon was the highest in the soil.Organic carbon content was 6.24g/kg,the soil organic carbon content in the traditional grain planting model was 6.51g/kg,and the organic carbon content of the grain feeding plant was 52% higher than that of the binary planting structure and 59% of the traditional planting structure.At the same time,the alfalfa in the grain rehousing mode was longer than that of the grain crops,and the utilization rate of crops could be improved by the crop growing season.The increase of vegetation coverage could also keep soil and water and prevent sand erosion.Alfalfa as a perennial leguminous crop,nitrogen fixation function can improve the quality of the soil,promote soil nutrient cycling,strong roots can increase the soil aggregate structure,reduce sand erosion.Considering the fragile ecological environment in Minqin area,the agricultural structure adjustment and the development of grassland agriculture,alfalfa cultivation,such as grassland cultivation is more beneficial than traditional food crops to protect the local ecological environment.3.The adjustment of agricultural planting structure in Minqin County,although economically beneficial and ecologically beneficial,lacks a new type of farmer cooperative organization that matches the structure of grain feeding.Local farmers have a low degree of understanding of farmer cooperatives and a certain understanding of only 19% of the total number of people.It should strengthen the publicity of farmers’ cooperatives.Farmers’ willingness to join farmers’ cooperatives is 61% of the total number of households The government is actively guiding the establishment of farmer cooperatives.Farmers’ cooperatives under the structural adjustment of grain and feed cultivation are different from the traditional forms ofpure cultivation or pure breeding cooperatives,and new farmer cooperatives with planting and breeding combined with grass and livestock need to be established so as to provide for agricultural structure adjustment The corresponding organizational security.
