淋盐水与土壤改良剂对玉米生长及品质的影响
Effect of Saline Drenching and Soil Amendments on the Growth Quality of Maize
摘要
Abstract
To address severe soil salinization,water scarcity,and low corn yields in Ningxia's Yellow River irrigation districts,this study analyzed the combined effects of irrigation quotas and soil conditioners on corn growth,yield,quality,water use efficiency,and output-to-input ratio under saline drainage water irrigation conditions.The study explores optimal management strategies for drip-irrigated corn,focusing on irrigation quotas and conditioners.The experiment employed drip irrigation technology,utilizing drainage water from rice fields.Two factors were set:irrigation quota S and soil conditioner F.Three drip irrigation levels(S1=1 725 m³/hm²,S2=2 175 m³/hm²,S3=2 625 m³/hm²),three soil conditioners(oligosaccharides,desalinization agent,and sulfur fertilizer designated as F1,F2 and F3),and one control treatment(CK)without soil conditioner application.Results indicated that the interaction between irrigation quota and soil conditioner significantly affected corn growth,yield,and quality(p<0.05).The S2F2 treatment yielded the highest output at 15.1 t/hm²,achieved the highest water use efficiency at 2.52 kg/m³,and demonstrated the highest output-to-input ratio at 1.87.Based on the entropy-weighted TOPSIS comprehensive evaluation results using entropy weights,the S2F2 treatment achieved the highest proximity score and the most favorable evaluation outcome.In summary,the optimal management strategy recommended for this region is an irrigation quota of 2 175 m³/hm² combined with the application of 150 kg/hm² of desalinization agent.关键词
