本文对关中灌区“吨粮田”、“双千田”（简称“两田”）开发及中低产田改造，从概念、特征、目标、措施、效益等方面进行了辩证分析，提出了彼此间的共性与个性特征，揭示了三者之间的相互关系，认为该地区属于中产地区，多数农田仍不具备“两田”开发的基本条件，从该区农业综合发展的战略角度考虑，应以中低产田改造为重点，积极为“两田”开发创造条件，在此基础上，加强“两田”开发的示范与推广，使三者有机的结合起来，促进该区农业向广度和深度发展。
In this paper, we conducted a dialectical analysis of the development of “Triticum”, “Shuangqiantian” (two fields) and the transformation of middle and low yield fields in Guanzhong Irrigation District from the aspects of concepts, characteristics, goals, measures and benefits. Commonality and individuality, revealed the interrelationship between the three, considered that the area belonged to the middle area, and most of the farmland still did not have the basic conditions for the development of “two fields.” From the strategic perspective of the comprehensive agricultural development in the area, On the basis of this, we should strengthen the demonstration and promotion of the development of “two fields” so that the three are organically integrated to promote the development of agriculture in a broad and deep scope in this area.
