摘要
以库尔勒香梨为试材,采用氨基酸叶面肥叶面喷施处理,研究了不同稀释倍数T1(1000倍液)、T2(800倍液)、T3(500倍液),CK(清水)叶面喷施对库尔勒香梨果实中游离氨基酸含量、外在品质和内在品质的影响,以期为科学施用氨基酸叶面肥提供参考依据。结果表明:与CK相比,T2、T3处理单果质量显著提高(P<0.05,下同),分别提高了6.74%、7.75%,T1处理与CK之间无显著性差异。T1、T2和T3处理下香梨果实纵径、横径和果形指数、可溶性固形物、纤维素、维生素C、总淀粉含量与CK无显著性差异;T3处理的果实还原糖、蔗糖、果糖和可溶性总糖含量均显著高于CK;氨基酸叶面肥能降低香梨果实中有机酸含量,其中T3处理的有机酸含量最低,与CK相比显著降低了37.55%。T1、T2和T3处理下香梨果实游离氨基酸含量均显著高于CK。综上所述,在库尔勒香梨果实膨大期进行叶面喷施氨基酸叶面肥有利于提高果实中游离氨基酸含量,改善果实品质。
Taking Korla fragrant pear as test material,the effects of foliar spray treatment with amino acid foliar fertilizer on free amino acid content,external quality and internal quality in fruits of Korla fragrant pear were investigated by using different dilutions of T1(1000 times of liquid),T2(800 times of liquid),T3(500 times of liquid),CK(clear water)foliar spray,in order to provide reference for scientific application of amino acid foliar fertilizer.The results showed that compared with CK,the single fruit weight of T2 and T3 treatment increased significantly(P<0.01,the same as below),by 6.74%and 7.75%respectively.There was no significant difference between T1 treatment and CK.There was no significant difference in longitudinal diameter,transverse diameter,fruit shape index,soluble solids,cellulose,vitamin C and total starch content between Korla fragrant pear and CK under T1,T2 and T3 treatments;the contents of reducing sugar,sucrose,fructose and total soluble sugar in T3 treatment were significantly higher than those in CK;amino acid foliar fertilizer could reduce the content of organic acids in Korla fragrant pear,and the content of organic acids in T3 treatment was the lowest,which was significantly reduced by 37.55%compared with CK.Under T1,T2 and T3 treatments,the content of free amino acids in Korla fragrant pear was significantly higher than that of CK.In conclusion,spraying amino acid foliar fertilizer on Korla fragrant pear during fruit expansion stage was beneficial to increase the content of free amino acids in fruit and improve fruit quality.
