Patterns of Influence of Meteorological Elements on Maize Grain Weight and Nutritional Quality

Meteorological factors are one of the important that determine maize kernel weight and grain nutritional quality. Analyzing influence meteorological before after anthesis on quality components is great significance for improving corn yield Therefore, five different hybrids conducted continuous experiments from 2018 to 2021 were selected in this study, explore response growth periods, quantify linear relationship between parameters, weight, factors. The main results as follows: 100-grain reached maximum value 39.53 g 2018; contents crude protein, total starch, fat grains 2018, 2020, respectively, which 9.61%, 69.2%, 5.1%. significantly affected (p < 0.05). Before anthesis, sunshine duration, average temperature, relative humidity, accumulated temperature had strong effects weight. After daily rainfall, difference, highest hours There was also a significant correlation multivariate polynomial equation analysis revealed further potential could be exploited by adjusting content each component kernels under current test conditions. elements can indirectly affect through their with grains, having greatest indirect effect pre-anthesis accumulation post-anthesis harmonized application lengths vegetation sowing time agricultural production. Ultimately, increased basis optimizing various grains.
