%X 以“四月慢”上海青为试验材料，研究了不同浓度高原夏菜尾菜沼液对上海青生长性状和品质的影响，以期为沼液的资源化利用提供科学依据。试验表明：上海青各处理在不同生育期的株高、单株鲜质重、根重、茎粗相较于对照组CK均有提高。幼苗期单株鲜质重在T4、T5处理上显著高于CK，对比CK分别增加了120.18%、105.88%，不同处理间均不存在显著差异。成长期不同处理对上海青株高、单株鲜质重、根重、茎粗均显著提高，T4处理单株鲜质重、根重、茎粗显著高于CK，分别提高了109.50%、142.79%、41.11%；T5处理在株高、单株鲜质重、根重、茎粗均显著提高，分别较CK提高了30.98%、111.30%、113.94%、41.07%。成熟期上海青株高、单株鲜质重、根重、茎粗随着尾菜沼液浓度的降低呈先增加后减少的趋势，株高、单株鲜质重、根重、茎粗均在T5时达到最大，较CK分别提高24.61%、129.91%、138.75%、48.86%，除株高外，单株鲜质重、根重、茎粗处理间均存在显著差异。叶绿素含量对比CK都有所提高，相较于CK，T1到T6处理分别增加36.04%、37.67%、43.02%、38.77%、57.97%和28.12%，不同的处理在叶绿素总含量上不存在显著差。随着沼液浓度的降低，维生素C含量先升高后降低，T2至T6维生素C含量均显著高于CK，分别提高了27.58%、44.85%、67.75%、73.56%、51.72%。CK处理可溶性糖含量最低，T5最高，T5对比CK增加了10.65%，不同处理在可溶性糖含量上存在显著性差异。硝酸盐含量随着沼液浓度的降低而降低，与CK相比，T6处理显著降低了12.61%。综合比较发现，本试验中T5 (1:15)处理效果最佳，由此表明，沼液施用不仅可以改善上海青品质，而且可以大量消纳沼液，但在沼液施用时需要合理选择沼液的用量。<br />
“April Slow” Shanghai cabbage was used as the experimental materials, we studied the effect of different concentrations of highland summer vegetable Biogas Slurry on the growth and quality of Shanghai cabbage, with a view to providing a scientific basis for the resource utilisation of biogas slurry. The experiment showed that the plant height, fresh mass weight, root weight and stem thickness of Shanghai cabbage in different fertility periods were improved compared with CK. Seedling fresh weight was significantly higher than that of CK in T4 and T5, with an increase of 120.18% and 105.88% respectively compared with CK, and there was no significant difference between different treatments. Different treatments during the growth period significantly increased the plant height, fresh mass weight, root weight and stem thickness of Shanghai cabbage, T4 was significantly higher than CK in fresh mass weight, root weight and stem thickness, which increased by 109.50%, 142.79% and 41.11%; T5 was significant in plant height, fresh mass weight, root weight and stem thickness, which respectively increased by 30.98%, 111.30%, 113.94% and 41.11%. At maturity, the plant height, fresh mass weight, root weight and stem thickness of Shanghai cabbage showed a trend of increasing and then decreasing with the reduction of the concentration of biogas slurry, and the plant height, fresh mass weight, root weight and stem thickness of Shanghai cabbage reached the maximum at T5, which increased by 24.61%, 129.91%, 138.75% and 48.86%, respectively compared with that of CK, except the plant height，there were significant differences in the fresh mass weight, root weight and stem thickness . Chlorophyll content was increased in all the treatments compared to CK, T1 to T6 treatments increased by
