Constitution Research for Precision Agricultural Technology Based on Value Chain Theory

This article presents the basic idea for analyzing increament link of agricultural production with value chain theory. Precision agricultural value chain model, which includes pre-production, in-production and post-production, is constructed based on information network technology, on the basis of analyzing such contradictions as equipment expensive, lack of technology, small plot, large risk and unsound infrastructure and so on which the application of precision agriculture fall across. On the premise of following market demand and practicability principle, technical composition system of precision agriculture is put forward taking senior technology guide, characteristic technology demonstration and primary technology as popularization emphases, assisted by perfect infrastructure technology and advanced management technology. So that refering to income for farmer and increasing surpluses as aim, localization step for our country precision agriculture technology is quichened, changing model from traditional agriculture to modern agriculture.
