Abstract
Double cropping in cotton fields is a prominent agricultural practice in the Yellow River basin, enhancing yields and overall cotton production benefits. However, there is limited research on the agronomic performance and long-term ecological sustainability of cotton-based cropping systems. This study evaluates the ecological service functions of various cotton-based cropping systems, focusing on crop productivity and ecological security. Field experiments were conducted to examine the dynamics of insect pest and natural enemy populations, soil nutrients, agricultural investment, and economic benefits across different cropping systems, including monoculture cotton with (MC1) or without chemical pesticides (MC2), garlic-cotton rotation with (GC1) or without chemical pesticides (GC2), wheat-cotton rotation with (WC1) or without chemical pesticides (WC2), and cotton-garlic intercropping with (CG1) or without chemical pesticides (CG2) in Jinxiang and Shanxian. The results showed that garlic-cotton rotation significantly improved species richness, conserved natural enemies, and enhanced economic benefits (GC1: +692.99%; GC2: +692.40%) compared to other systems. However, wheat or garlic rotation without pest control significantly decreased soil organic matter. Overall, garlic-cotton rotation proved to be a sustainable and efficient cropping system for traditional cotton-growing areas in the Yellow River basin, providing theoretical and technical support for environmentally friendly cotton production in China.
期刊介绍：
Food and Energy Security seeks to publish high quality and high impact original research on agricultural crop and forest productivity to improve food and energy security. It actively seeks submissions from emerging countries with expanding agricultural research communities. Papers from China, other parts of Asia, India and South America are particularly welcome. The Editorial Board, headed by Editor-in-Chief Professor Martin Parry, is determined to make FES the leading publication in its sector and will be aiming for a top-ranking impact factor.
Primary research articles should report hypothesis driven investigations that provide new insights into mechanisms and processes that determine productivity and properties for exploitation. Review articles are welcome but they must be critical in approach and provide particularly novel and far reaching insights.
Food and Energy Security offers authors a forum for the discussion of the most important advances in this field and promotes an integrative approach of scientific disciplines. Papers must contribute substantially to the advancement of knowledge.
Examples of areas covered in Food and Energy Security include:
• Agronomy
• Biotechnological Approaches
• Breeding & Genetics
• Climate Change
• Quality and Composition
• Food Crops and Bioenergy Feedstocks
• Developmental, Physiology and Biochemistry
• Functional Genomics
• Molecular Biology
• Pest and Disease Management
• Post Harvest Biology
• Soil Science
• Systems Biology
