本研究旨在评估不同种植模式对红壤理化性质及大豆品质的影响，以确定最适合大豆的种植模式。采用单因素方差分析法对比分析了大豆单作、玉米间作大豆和木薯间作大豆不同种植模式对红壤理化性质(pH、电导率和有机质、水解性氮、全磷、速效钾含量)和大豆营养品质(糖、粗蛋白、粗脂肪含量)的影响，并采用PLSR分析法探究红壤理化性质与大豆品质的关系。结果表明，木薯与大豆间作模式显著提高了红壤的pH、电导率、水解性氮以及大豆中的粗蛋白质和粗脂肪含量(P＜0。05)，其有机质和速效钾含量也相对较高。PLS2分析结果显示，土壤pH和电导率与品质指标具有显著相关性。进一步的PLS1分析揭示了电导率与糖含量呈显著负相关，与粗脂肪含量呈显著正相关;而土壤pH和电导率与大豆粗蛋白质含量呈现著正相关(P＜0。05)。土壤pH和电导率对大豆品质的影响较大。木薯间作大豆对改善红壤pH和电导率、提高大豆营养品质具有积极效果，其种植模式优于玉米间作大豆。
Effects of Intercropping Patterns on Physicochemical Properties of Red Soil and Soybean Qualities
The aims are to explore the effects of different soybean planting patterns on the physicochemical properties of red soil and soybean quality and identify suitable planting patterns for soybeans,providing theoretical basis for improving the physicochemical properties of red soil and the nutritional quality of soybeans,and guide production practice.The one-way ANOVA method was used to compare and analyze the effects of different planting modes of soybean monoculture,maize-soybean intercropping and cassava-soybean intercropping on the physicochemical properties(pH,electrical conductivity and organic matter,hydrolytic nitrogen,total phosphorus,and available potassium contents)of red soil and the nutritional qualities(sugar,crude protein and fat contents)of soybean.The PLSR analysis method was used to explore the relationship between the physicochemical properties of red soil and soybean qualities.The pH,electrical conductivity,hydrolytic nitrogen,crude protein and fat content of cassava-soybean intercropping were significantly higher than those of soybean monoculture(P＜0.05),and their organic matter and available potassium contents were also relatively higher.The PLS2 analysis results showed that there was a significant correlation between the pH and electrical conductivity of red soil and quality indicators of soybeans.The PLS 1 analysis further found that there was a significant negative correlation between electrical conductivity and sugar content,and a significant positive correlation with crude fat content;the pH and electrical conductivity of red soil are positively correlated with the crude protein content of soybeans(P＜0.05).The pH and electrical conductivity of soil have a significant impact on the quality of soybeans.Cassava-soybean intercropping has a positive effect on improving the pH and electrical conductivity of red soil as well as improving the nutritional quality of soybean.The planting mode is superior to maize-soybean intercropping.
