Research progress in the application of microbial fertilizers in chemical fertilizer reduction and efficiency increase in orcharding

Abstract:

The production of green and high-quality agricultural products has become a new trend, especially in the context of developing green agriculture. However, the excessive use of fertilizers and pesticides in orcharding has caused severe pollution of the farmland environment, resulting in low-quality fruits and posing a threat to human health. Microbial fertilizers are a new type of green fertilizers that contain beneficial microorganisms to enhance soil ecology, promote plant development, and increase productivity and can reduce the application of chemical fertilizers. Although the current research on microbial fertilizers is limited to a few microbial species and single crops, the studies have shown the potential of microbial fertilizers in improving soil, yield, and plant quality, while the mechanisms and effectiveness of these fertilizers need systematic investigation. Therefore, this article reviews the mechanisms of microbial fertilizers in improving soil ecology and enhancing plant resistance to disease and stress. Taking fruit trees as an example, we focus on the application of microbial fertilizers in improving the fruit yield and quality as well as the agricultural environment. In addition, we discuss the technical bottlenecks and put forward new research ideas and directions, aiming to provide theoretical references for improving the agricultural environment and promoting sustainable agricultural development.
