农田土壤改良与肥料利用效率提升策略
摘 要
农田土壤改良与肥料利用效率提升是现代农业可持续发展的重要课题。本研究旨在探讨通过综合土壤改良措施提高肥料利用效率的可行性。研究背景基于中国农田土壤普遍存在的养分失衡和肥力下降问题，这些问题严重制约了农业生产力的提升。研究方法包括田间试验、实验室分析和数据模型构建。在田间试验中，我们选择了不同类型的土壤和作物，应用有机肥、生物炭和微生物菌剂等改良措施，并监测其对土壤理化性质和作物产量的影响。实验室分析则用于评估改良措施对土壤养分循环和微生物群落结构的影响。数据模型构建旨在预测不同改良措施的长期效果和经济效益。研究结果显示，综合应用有机肥和生物炭显著改善了土壤结构和养分状况，提高了肥料的利用效率，平均增产率达到15%以上。

FARMLAND SOIL IMPROVEMENT AND FERTILIZER UTILIZATION EFFICIENCY IMPROVEMENT STRATEGY
ABSTRACT
Farmland soil improvement and the improvement of fertilizer utilization efficiency are the important topics for the sustainable development of modern agriculture. The aim of this study was to investigate the feasibility of improving fertilizer utilization efficiency through comprehensive soil improvement measures. The research background is based on the widespread nutrient imbalance and fertility decline in China's farmland soil, which seriously restrict the improvement of agricultural productivity. Research methods included field trials, laboratory analysis, and data model construction. In field experiments, we selected different types of soil and crops, applied improvement measures such as organic fertilizers, biochar and microbial agents, and monitored their effects on soil physiochemical properties and crop yield. Laboratory analyses were used to assess the impact of improvement measures on soil nutrient cycling and microbial community structure. The data model construction aims to predict the long-term effects and economic benefits of the different improvement measures. The results show that the comprehensive application of organic fertilizer and biochar has significantly improved the soil structure and nutrient status, and improved the utilization efficiency of fertilizer, with the average yield increase rate reaching more than 15%.
