不同种植方式对甘蓝生长发育、产量和品质的影响OA

To clarify the regulatory effects of different planting methods on the growth,yield,and quality of cabbage,five planting methods,including flat-bed double-row(T1),high-ridge single-row(T2),high-bed single-row(T3),high-ridge double-row(T4),and high-bed double-row(T5),were established in 2024-2025.The growth indicators,photosynthetic characteristics,biomass accumulation,soil moisture status,yield composi-tion,and quality differences under each treatment were systematically compared to select the suitable planting method for cabbage.This provides a theoretical basis and practical guidance for mechanized transplanting and high-quality and efficient production in the southern mountainous areas of Ningxia.The results showed that the T1 treat-ment could effectively promote the growth of cabbage,increase photosynthetic efficiency and biomass accumulation,and improve soil moisture status,significantly enhancing cabbage yield and quality.Compared with other treat-ments,T1 treatment exhibited a 0.29％-25.55％increase in cabbage spread width,leaf length,stem diameter,and net photosynthetic rate during the two-year harvest period.The fresh weight of the above-ground and below-ground parts,as well as the dry weight of the below-ground parts,increased by 2.86％-51.04％during the heading and harvest periods.Soil moisture content during the harvest period increased by 0.34％-2.83％.In terms of yield and quality,the single plant weight of T1 treatment was 4.02％-17.00％higher than that of other treatments,and quality indicators such as soluble solids,vitamin C,and soluble protein increased by 0.09％-25.00％.Principal component analysis indicated that T1 treatment had the highest comprehensive score(0.74).In summary,the flat-bed double-row cultivation mode exhibited the best comprehensive performance and can be recommended as the main cultivation mode for cabbage in the southern mountainous areas of Ningxia.
