In order to eliminate the weakness of agriculture and to accelerate the development of modern agriculture，we should increase the agricultural production based on reducing the input of chemical fertilizer and pesticides，increase the irrigation area based on reducing the total amount of agricultural water，and increase agriculture based on the improvement of total factor productivity contribution rate. To achieve this goal，we must deepen the reform of the rural land system，collective economy and rural governance，and replace the policy of avoiding risks to the policy of encouraging farmers to pursue benefit policy，turn the yellow box policy to the green box policy，replace the physical property policy to the value formed property policy，and change policies into laws and regulations.
