摘要： 黄淮海地区光、热、水资源较丰富,气候-土壤资源的生产潜力较大。本文在对作物各层次生产力计算方法研究的基础上,对该地区冬小麦、夏玉米、夏大豆、棉花等作物各层次生产力进行了计算。初步认为,在一定的农业技术水平条件下,近期(2000年以后)粮棉生产力比1989年可增加1/3,远期(30～50年以后)可增加1倍或稍多。

Abstract: The productivities of different grain crops (winter wheat,summer corn and summer soybean) and cotton were estimated and analysed for different input levels based on the climatic and agricultural data, It was concluded that the yields of grain crops and cotton can be increased by third in ten years and can be doubled in 30 to 5U years in co mparison to that in the year of 1987.
