摘要： 为了回答河南省可实现粮食生产潜力问题，基于河南省测土配方试验、施肥示范试验数据和河南省耕地地力评价成果，测算了在试验条件下河南省可实现粮食生产潜力。结果表明：河南省小麦、玉米、水稻在测土配方施肥试验和施肥示范推广试验条件下，最高单产的平均值分别为4726.2、5817.6、5409.15 kg/hm2。河南省可实现粮食生产潜力为7487.27万t，河南省粮食生产目前还有约35%的增产空间。

Abstract: In order to answer the question of potential grain productivity in Henan Province, this paper estimated potential grain productivity under the experimental conditions using data of soil test and fertilizer demonstration test and evaluation results of cultivated land fertility in Henan Province. The results showed that the average values of the highest yields of wheat, corn, rice under the experimental conditions of using data of soil test and fertilizer demonstration test were 4726.2, 5817.6 ,5409.15 kg/hm2, respectively. The potential grain productivity that Henan could achieve was 74.8727 million tons, increasing by 35% from the present level.
