沼液叶面施用对辣椒产量及品质的影响

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%。

Effect of Biogas Slurry Foliar Fertilizer on Yield and Quality of Hot Pepper

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.
