摘　　要：对辣椒叶面喷施不同浓度沼液,结果表明:沼液可促进辣椒的生长发育,提高产量;还可改善辣椒的品质,提高辣椒的可溶性糖和维生素C含量,减少硝酸盐含量。以喷施60%的处理产量最高,比对照增产14.9%;以及维生素C含量最高,比对照增加40.2%。以喷施80%的处理可溶性糖含量最高,比对照提高24.2%;以及硝酸盐含量最低,比对照下降20.5%。Biogas slurry at different concentrations was sprayed on leaves of hot pepper. The result showed that biogas slurry could promote growth and development of hot pepper, and increase yield; and it could also improve quality of hot pepper, increase contents of soluble sugar and vitamin C （Vc）, and decrease nitrate content. Spraying biogas slurry at the concentration of 60% got the highest yield which increased by 14.9% and the highest content of Vc, concentration of 80%, it which increased by 40.2%, as compared with the CK, respectively; and at the got the highest content of soluble sugar which increased by 24.2% and the lowest nitrate content which decreased by 20.5%, as compared with the CK, respectively.
