摘要

背景中国的食糖生产正努力跟上食糖消费快速增长所带来的需求增长。本研究旨在探讨环境和管理因素对甘蔗产量和质量(以含糖量为特征)的影响。此外,本研究还试图确定如何通过优化生产,以较少的资源投入满足中国未来的甘蔗需求。方法本研究进行了全面搜索,从 64 篇关于中国甘蔗生产的同行评审出版物中收集了 411 组测量数据。此外,还根据试验数据和农民调查数据建立了随机森林模型,以预测中国县级甘蔗产量和质量。考虑到 2030 年中国的甘蔗需求预测,本研究提出了三种甘蔗种植方案,以探索未来甘蔗生产的潜在途径。这些情景包括S0,所有甘蔗种植面积保持现有生产水平;S1,中低产(或优质)甘蔗田过渡到中高产(或优质)甘蔗田;S2,所有甘蔗种植面积努力实现高产和优质。结果结果表明,整体田间管理可使产量提高 37.1%,质量提高 5.26%。土壤有机质 (SOM)、可利用磷 (AP)、年平均降水量 (MAP) 和土壤粘度是影响产量的最重要因素;pH 值、AP、全氮 (TN) 和 SOM 是影响质量的最重要因素。在满足 2030 年甘蔗需求的基础上,S2 方案的土地投入减少了 11%,养分投入减少了 5%,灌溉投入减少了 13%。我们的研究提供了一个概念框架,使中国能够以更高效、更环保的方式满足未来的食糖需求和消费,从而节约资源并减少对环境的影响。

Integrated management to achieve synergy in sugarcane production and quality in China

Context

Sugar production in China is struggling to keep up with the increasing demand driven by rapid growth in sugar consumption. However, knowledge gap persists in terms of how to locate and concentrate the sugarcane production in advantageous areas to secure the production of high-quality sugarcane characterized by high sugar content, while also optimizing resource utilization.

Objective

The objective of the study was to explore the effects of environmental and management factors on sugarcane yield and quality (characterized by sugar content). Moreover, it sought to determine how China's future sugarcane needs could be met with fewer resource inputs through production optimization.

Methods

This study conducted a comprehensive search and compiled 411 groups of measured data from 64 peer-reviewed publications on sugarcane production in China. Additionally, a Random Forest model was developed based on trial data and farmer survey data to predict county-level sugarcane yield and quality in China. Taking into consideration China's projected sugarcane demand in 2030, this study proposed three sugarcane planting scenarios to explore potential pathways for future sugarcane production. These scenarios included: S0, where all sugarcane acreages maintain their current level of production; S1, where medium- and low-yield (or quality) fields transition into high- and medium-yield (or quality) fields; and S2, where all sugarcane acreages strive for both high yield and high quality.

Results

Results showed that overall field management could improve yield by 37.1 % and quality by 5.26 %. Soil organic matter (SOM), available phosphorus (AP), mean annual precipitation (MAP), and soil clay are the most important drivers of yield. pH, AP, total nitrogen (TN), and SOM are the most important drivers of quality. S2 scenario reduced land inputs by 11 %, nutrient inputs by 5 %, and irrigation inputs by 13 %, based on meeting future sugarcane demand in 2030.

Conclusions

By identifying and focusing on dominant planting areas, we can enhance the quality and efficiency of sugarcane cultivation as a response to China's future demand for sugarcane. This approach will not only meet future demands for sugarcane but also alleviate the dual pressures of limited resources and environmental concerns.

Significance

Our research provides a conceptual framework to enable China to meet its future sugar demand and consumption more efficiently and in an environmentally friendly manner, thereby conserving resources and reducing environmental impact.
