Abstract:

Using humic acid water-soluble fertilizer produced by Zhongcheng Guolian (Henan) Biotechnology Co., Ltd. as the test material, this study investigated the impact of foliar application of humic acid water-soluble fertilizers on the yield and yield factors of wheat and summer maize under different soil texture types in Shangqiu City. The paired test design was used, and the effects on economic benefits were also analyzed. The results showed that with foliar spraying of humic acid water-soluble fertilizer, the number of grains per ear, 1000-grain weight and both yield and economic benefits significantly increased. Statistical analysis revealed a highly significant increase in yield for both wheat and summer maize. The increase in yield and economic benefit varied across different soil texture types. For wheat, the highest yield increase and lowest yield increase rate occurred on silty soil. The highest increase rate and smallest yield increase were found on sandy soil. The order of net increase in economic benefit was silty soil> loamy soil> sandy soil. For summer maize, the yield increase ranking was silty soil> sandy soil> loamy soil, while the orders of increase rate and net increase in economic benefit were loamy soil> silty soil> sandy soil.
