Analysis of Developing about Wheat Harvesting Mechanizationin in Tianjin City

On the basis of field surveying and literature analyzing，the present situation of wheat harvesting mechanization was introduced in Tianjin，and the level of wheat harvesting mechanization was 99%.The factors（wheat harvesterwas full，the profit of mechanical reaping among provinces was reduced，and the degree of straw conversion utilization was low）of affecting wheat harvesting mechanization were analyzed.Moreover the proposal about developing wheat harvesting mechanizationin in Tianjin was put forward.
