大豆种植中的肥料利用效率与减排措施研究 -农学专业

摘要

本文以大豆种植中的肥料利用效率与减排措施研究为目标，通过综合文献回顾和案例分析，探讨了大豆种植中存在的肥料利用效率问题，并提出了一系列减排措施。研究发现，大豆种植中的过量施肥和不合理施肥技术导致了养分浪费和环境污染。为提高肥料利用效率及减轻环境压力，本文提出了优化肥料施用技术、改善土壤肥力管理和推广有机肥料的使用等多种减排措施。在优化肥料施用技术方面，水肥一体化技术、控释肥料的应用、精准施肥技术和微生物肥料的应用等方法被提出并得到有效应用。针对土壤肥力管理问题，通过轮作制度、绿肥的应用和增施有机肥等手段提高土壤养分含量和肥力。此外，通过推广有机肥料的使用，促进了大豆生产中的肥料可持续利用，有机肥料的添加改善了土壤质量，进而增加了农作物产量。本研究结果表明，在大豆种植中采取合理的肥料利用方法和减排措施可以提高农业生产的可持续性，同时降低了对环境的不良影响。

STUDY ON FERTILIZER UTILIZATION EFFICIENCY AND EMISSION REDUCTION MEASURES IN SOYBEAN PLANTING

ABSTRACT

Aiming at the study of fertilizer use efficiency and emission reduction measures in soybean planting, this paper discusses the problems of fertilizer use efficiency in soybean planting through comprehensive literature review and case analysis, and puts forward a series of emission reduction measures. It was found that excessive fertilization and unreasonable fertilization techniques in soybean planting resulted in nutrient waste and environmental pollution. In order to improve fertilizer utilization efficiency and reduce environmental pressure, various emission reduction measures such as optimizing fertilizer application technology, improving soil fertility management and promoting the use of organic fertilizers were proposed in this paper. In terms of optimizing fertilizer application technology, methods such as water and fertilizer integration technology, application of controlled release fertilizer, precision fertilization technology and application of microbial fertilizer have been proposed and effectively applied. Aiming at the problem of soil fertility management, soil nutrient content and fertility were improved by means of crop rotation system, application of green fertilizer and increasing application of organic fertilizer. In addition, by promoting the use of organic fertilizers, the sustainable use of fertilizers in soybean production is promoted, and the addition of organic fertilizers improves soil quality, which in turn increases crop yields. The results of this study show that reasonable fertilizer utilization and emission reduction measures in soybean planting can improve the sustainability of agricultural production and reduce the adverse impact on the environment.
