| 摘 要： | 河南省中低产田面积较大，约占全省耕地面积的64．8％。要保证河南省粮食的持续增产和安全供给，除了靠扩大面积外，根本出路在于改造中低产田，发展高标准粮田，提高粮食单产。干旱灌溉型和瘠薄培肥型是河南省中低产田的2个主要类型区，两者共占近60％。在总结前人研究成果的基础上，分别探讨了干旱灌溉型和瘠薄培肥型的基本特征和改造措施，以期为河南省的中低产田改造提供参考。

| Abstract: | The area of middle-low yield fields in Henan is large, accounted for 64.8% of the arable land area in the province. In order to guarantee sustainable increasing and safety supply of grain in Henan Province, except for enlarging cultivated land area, the key way is trans- forming middle-low yield fields, developing high standard field and increasing grain yield per unit. Drought irrigation and barren fertility type are two main types of middle-low yield field in Henan Province, accounted for 60%. On the basis of summarizing research achievements, the basic features and modification measures for drought irrigation and barren fertility type field were discussed, so as to provide reference for mod- itlcation of middle-low yield fields in Henan Province. |
