Retraction Note: Comparative analysis of nutritional components of maize with different planting densities from the perspective of ecological environment

Abstract

The yield and quality of maize grains are determined by genotype and environmental factors. Through a systematic comparison of the density effects of maize yield and quality of different plant-type varieties grown on land under four different ecological environments in a certain province, and the differences in maize yield and quality in different ecological regions, the reasons for the differences were analyzed. The results showed that differences in light, accumulated temperature, and precipitation are important reasons for yield differences, and these factors are also key factors affecting maize grain quality. Taking the southern ecological zone as an example, the effects of different planting densities on the content of nutrients such as protein, starch, and fat in maize grains were studied. The study found that with the increase of planting density, the grain protein content decreased significantly, while the increasing and decreasing trend of protein, fat, and starch content (PFSC) was more complicated. By formulating maize varieties, density, and other related control measures to make full use of ecological resources and give play to regional advantages, high-quality and high-yield maize can be achieved.
