摘要
探明不同种类叶面肥对柑橘果实品质及产量的影响,可为柑橘提质增效提供理论依据。以柑橘品种宫川为试材,设置喷施清水对照、磷酸二氢钾、奇茵及欧甘4个处理,比较分析各处理对柑橘果实品质及产量的影响。结果表明,不同水溶肥对果实的单果重、纵径、横径及净重的影响差异不显著。喷施叶面肥磷酸二氢钾、奇茵、欧甘处理可溶性固形物含量和可滴定酸含量较喷施清水对照有所增加,其中喷施奇茵处理可溶性固形物含量和可滴定酸含量最高,分别为9.39%、0.75%,显著高于喷施清水对照,可溶性固形物含量较喷施清水提高了14.93%,可滴定酸含量较喷施清水提高了19.05%。喷施奇茵、欧甘、磷酸二氢钾处理单株挂果数分别较喷施清水高31.59%、16.28%、4.46%,产量分别较喷施清水高12.96%、6.57%、3.00%。由此表明,喷施叶面肥能提高柑橘果实品质和产量,以喷施奇茵叶面肥处理综合效果较好。
In order to explore the effects of different types of foliar fertilizers on the quality and yield of citrus fruits,and provide a theoretical basis for improving citrus quality and efficiency,this paper used the citrus variety Gongchuan as the experimental material,and set up four treatments,including spraying water control(CK),potassium dihydrogen phosphate(T_(1)),Qiyin(T_(2)),and Ougan(T_(3)).The effects of each treatment on the quality and yield of citrus fruits were compared and analyzed.The results showed that there was no significant difference in the effects of different water-soluble fertilizers on the single fruit weight,longitudinal diameter,transverse diameter,and net weight of the fruit.After spraying the foliar fertilizers,the soluble solid content and titratable acid content of T_(1),T_(2),and T_(3) increased compared with CK.The soluble solid content and titratable acid content of T_(2) were the highest,reached 9.39%and 0.75%,respectively,which were significantly higher than those of CK.Compared with CK,the soluble solid content of T_(2) increased by 14.93%and the titratable acid content of T_(2) increased by 19.05%.The numbers of fruits per plant of T_(2),T_(3),and T_(1) were 31.59%,16.28%,and 4.46% higher than those of CK,respectively.The yield of T_(2),T_(3),and T_(1) were 12.96%,6.57%,and 3.00%higher than those of CK,respectively.This indicated that spraying foliar fertilizer could improve the quality and yield of citrus fruits,and the treatment of spraying Qiyin had a better overall effect.
