摘要:

为突出土壤条件变化对粮食产量的影响,采用趋势分析法和对比分析法,以兰考县耕地资源质量分类监测工作为例,分析土壤监测样点不同年份的土壤条件变化对当地粮食产量造成的影响。研究表明,土壤有机质含量的增加和土壤pH在合理范围内的增加都能够提升粮食产量。建议以测土配方施肥为基础,增加有机肥的使用量,提升土壤有机质含量,并针对当地土壤的实际情况和主要作物类型,提出有针对性的改良土壤pH的措施,以提升粮食产量。

Abstract:

This study utilized trend analysis and comparative analysis methods to analyze the changes of soil conditions over various years at soil monitoring sample points and their subsequent effects on grain yield, using data extracted from the cultivated land resource quality classification monitoring in Lankao County. The findings demonstrated that enhancements in grain yield could be attributed to the increase of soil organic matter content and a reasonable augmentation of soil pH. For the purpose of yield optimization, it was suggested that the utilization of organic fertilizers should be increased on the premise of soil testing and formula fertilization, consequently ameliorating the soil organic matter content. Concurrently, context-specific measures for improving soil pH should be devised, considering the unique characteristics of the local soil and the types of predominant crops.
