Abstract: There were some harmful phenomena on agriculture in this country now，for example，unsuited structure，lower profit，little support on policy，poor market competitiveness of products，etc. It was suggested that the ratio relationship between agriculture，forestry，animal husbandry，fishery should be adjusted，and that some structure，for example，agricultural industries，products，essential factors of production and trade should be adjusted too. All of this is based on a whole production system and sustainable development of rural economy. Agriculture should be evaluated from various angles and different stratifications。It was also suggested that superior industry，especially for characteristic products，should be developed energetically，yield of croup should be controlled to suitable scope according to plan，and the ratio of animal husbandry of whole agriculture should be increased。It is more important that the role of technology and improvement of production regulations should not be neglected，a simple change of breeds within cropping could not free whole agriculture from backwardness at all.
