- 为解析黑土肥力变化对大豆产量及品质的影响,从而有针对性地调节大豆产量与品质,以黑土坡耕地为研究基础,以单施化肥(不施用有机物料)为对照,分别配施有机肥、秸秆、生物炭3种有机物料对土壤进行培肥研究。采用相关分析、多元逐步回归和通径分析法,分析了不同培肥措施下坡耕黑土肥力变化及其对大豆品质与产量的影响。结果表明,有机培肥处理下土壤有机碳含量平均增加8.23%~15.01%,大豆产量平均提升10.89%~19.00%,籽粒蛋白质含量提升1.24%~2.05%。有机碳对大豆产量的直接与间接综合作用较强; 土壤肥力通过直接和间接作用共同影响着大豆品质,可联合解释大豆品质及产量性状变异性的78.0%~99.2%,但各肥力因子的作用机理和影响强度不同。土壤全氮在大豆籽粒蛋白质含量中体现为直接正效应(0.366),而在大豆籽粒脂肪、灰分含量中则呈直接负效应(-0.892,-0.270); 速效钾在大豆籽粒蛋白质、脂肪含量中体现为较强的直接正效应(1.605,1.406),在大豆籽粒灰分含量中则呈直接负效应(-1.465)。三种培肥措施不同程度提升了土壤肥力、大豆产量及品质,以配施有机肥效果最佳; 土壤全氮、速效钾在蛋白质、脂肪、灰分3种大豆产量及大豆品质指标的变化中均起到了较强的主导作用,土壤速效磷、有机碳、全钾含量的直接及间接作用也是大豆产量及品质变异的主要作用因子。
- Abstract:
- This paper analyzed the effect of black soil fertility on soybean yield and quality in order to adjust the yield and quality of soybean. Black soil sloping farmland was used as the research basis, single fertilizer application (no organic materials) was used as the control, and the soil was fertilized with organic fertilizer, straw and biochar. Correlation analysis, multiple stepwise regression and path analysis were used to study the change of fertility of black soil and its effect on soybean yield and quality. The results showed that the organic carbon content of soil increased by 8.23%-15.01%, the yield increased by 10.89%-19.00% on average, and the protein content of soybean increased by 1.24%-2.05% under three treatments of organic fertilizer. The direct and indirect effects of organic carbon on soybean yield were strong. Soil fertility influenced soybean quality through direct and indirect effects, which could jointly explain 78.0%-99.2% of the variation of soybean quality and yield characters, but the action mechanism and influence intensity of each fertility factor were different. Soil total nitrogen showed a directly positive effect (0.366) in soybean protein content, but a directly negative effect(-0.892, -0.270) in soybean fat and ash content. The available potassium showed a strong directly positive effect (1.605, 1.406) in protein and fat content of soybean, and a directly negative effect (-1.465) in ash content of soybean. Soil fertility, soybean yield and quality were improved under three fertilization measures. Soil total nitrogen and available potassium all played a strong leading role in the changes of soybean yield and protein, fat, and ash content of soybean. The direct and indirect effects of soil available phosphorus, organic carbon and total potassium are also the main factors of soybean yield and quality variation.
