| 摘 要： | 为揭示农田投入对不同质量耕地粮食产量及经济效益的影响,以太行山北段冀中山前平原冬小麦、夏玉米一年两熟区为例,运用农用地分等成果,借助因素组合、假设检验及回归分析等方法对农田投入在不同质量耕地上的响应程度进行分析.结果显示:同一因素组合类型耕地,投入较低时,科学合理地增加农田投入,可提高粮食产量;科学合理的农田投入可使研究区自然质量较差耕地达到高产目的:产投效益最大值和粮食产量最大值之间的投入区间为最合理农田投入区间;同一农田投入水平下,据耕地自然因素对粮食产量的不同影响及耕地因素组合类型,合理调整投入方向,粮食增产效果更显著.

| Abstract: | To analyze the effect of field input on grain yield and economic benefit of farmlands, we used wheat-corn double crop-ping fields in northern Taihang Mountain Plain region of central Hebei to analyze the degree of response to input from farmland quality on basis of factor combination, hypothesis testing, regression analysis and agricultural land grade. The results suggest that grain yield can be improved by scientifically and reasonably increasing field input or using a combination of factors at low input. High yield on farmlands with poor natural conditions can be achieved through scientific and reasonable input. The optimal value of field input is within the interval between the maximum input-output benefit and maximum grain yield. Reasonably adjusted input based on differences in the influence of natural factors on grain yield and different factor combinations can increase yield significantly. |
