施用有机肥对土壤理化性质及黄豆品质的影响
Effects of single and mixed organic fertilizer applications on soil physicochemical properties and soybean quality
摘要
Abstract
To explore the effects of single and mixed applications of different organic fertilizers on soybean quality and soil physicochemical properties,a pot experiment was conducted using soil from the farm at the Baiyun Campus of Zhongkai University of Agriculture and Engineering as the planting substrate,with soybeans as the test crop.The experimental fertilizers comprised Tugengwang bio-organic fertilizer(Fertilizer 1)and Guangzhengfeng earthworm cast raw fertilizer(Fertilizer 2).All fertilization treatments were set at 5%of the dry soil mass,resulting in six distinct treatment groups.The results showed a notable improvement in nitrogen,phosphorus,and potassium content of soybean stems using Fertilizer 1.It yielded increases of 18.45%,141.52%,and 8.34%compared to mixed fertilization,and 23.66%,306.91%,and 24.95%compared to the original soil.Both single and mixed applications were found to affect soybean protein content.However,the protein content was negatively correlated with starch and reducing sugar content.For soil improvement,both fertilization methods demonstrated effectiveness in improving indicators such as soil pH,organic matter,and moisture content.Among these,the application of Fertilizer 2 positively affected organic matter,available nitrogen,and available phosphorus,with increases of 177.67%,143.23%,and 102.13%.The corresponding increases for mixed applications were 116.50%,109.06%,and 42.55%.This study provides a scientific reference for developing fertilization strategies of soybean production in acidic red soil regions.关键词
