Adjustment Of Planting Structure Based On Compartive Advantage In Heilongjiang Province

Scientific analysis and research on regional planting industry layout,promotion of planting industry structure adjustment and regional scale distribution and development of modern planting industry are the basic requirements for accelerating the process of modern agriculture and realizing modern agricultural model,as well as a major issue concerning national economy and people's livelihood.Agricultural planting area structure is mainly based on the regional natural resources and regional development of planting industry has always been,rational planting of crops in a certain region within the scope of the model for depth research,development has the special advantage of regional leading industries and pillar industries of agricultural planting structure,scale industry is the Heilongjiang province agricultural scale,modernization and characteristic development facing a big problem.The scientific and reasonable adjustment of planting industry structure is also of great significance for the efficient large-scale development of inter-regional planting industry.Based on the structure of planting industry in Heilongjiang province time sequence evolution and regional planting industry structure difference characteristic data,analyzes the main reason for the change,and use the method of comprehensive comparative advantage index(including efficiency,scale index and benefit index),calculate the Heilongjiang rice,wheat,corn,soybean,potato,sugar beet,comprehensive advantage index of flue-cured tobacco seven categories of crops,so as to give a specific adjustment opinions and Suggestions.The results of the study on crop adjustment of regional planting industry were analyzed and determined: the planting of soybean should be increased in Daxinganling,Mudanjiang,Qitaihe and Jiamusi,etc.Most areas in the province,such as Hegang,Shuangyashan,Daqing,Jiamusi,Mudanjiang,Suihua,should reduce the amount of wheat planting;The planting of rice in the southeastern areas of Heilongjiang province such as Yichun,Hegang,Jiamusi and Jixi should be vigorously promoted.In the southeast,such as Qiqihar,Daqing,Suihua and Harbin,the planting scale and intensity of corn should be increased.Generally,the growing amount of potatoes in different parts of the province is fairly uniform.The best selection location of the sugar beet planting area is Qiqihar.Mudan river and Qitaihe should increase the intensity of planting flue-cured tobacco.And auxiliary optimization advice and constructive Suggestions are given through the data,improve the planting structure adjustment direction of Heilongjiang province,makes the crop yield is higher,more substantial economic income of farmers,agricultural products market is more fresh and smooth circulation,the big province of grain in Heilongjiang province in agricultural development process more steps,to build a well-off society in an all-round way the pace of more solid.
