1965年～1996年，30a间汝阳县共修建水平梯田6000hm2，占总坡耕地面积的39．1％。总结多年来梯田建设经验，可用弯、厚、拱、长、平5个字表述。据试验测定，水平梯田径流系数为0．27，保水、保肥，改善土壤结构，粮食产量大幅度提高，综合效益显著。然而，近几年来，全县新修梯田保存率平均不足80％，个别地区降至50％，而且投入逐渐减少。分析原因主要有政策因素、技术因素及精神因素。欲要利用15a时间（2010年）将全县坡耕地全部修成水平梯田，必须做好规划设计，完善管理政策，强化技术服务，提高全面素质。
From 1965 to 1996, a total of 6000hm2 terraces were built in Ruyang County in 30a, accounting for 39.1% of the total cultivated land area. Summarized over years of experience in the construction of terraces, available bend, thick, arch, long, flat 5 words. According to the test, the runoff coefficient of horizontal terraces is 0.27, which ensures water retention and fertilizer retention, improves soil structure, greatly increases grain yield and has significant comprehensive benefits. However, in recent years, the preservation rate of newly repaired terraces in the whole county has been on the average less than 80%, while that in some areas has dropped to 50% and the investment has been gradually reduced. Analysis of the main reasons for the policy factors, technical factors and spiritual factors. If we want to make use of 15a time (2010) to make all the cultivated slopes of the entire county a terrace, we must make planning and design, improve management policies, strengthen technical services and improve overall quality.
