| 摘 要： | 探讨在施用化肥的基础上增施有机肥对番石榴一年两批果实产量和品质的影响,以期为番石榴科学施肥提供依据。以‘红香1号’番石榴为研究对象,以单施化肥为对照,比较每株增施有机肥2.5、5.0、7.5、10.0 kg对番石榴果实外观性状、产量、品质和经济效益的影响。结果表明：在施用化肥的基础上,增施有机肥可增加单果质量,增大纵径、横径和果形指数,改善果实外观性状,提高产量,同时提高了果实可溶性固形物、Vc、可溶性糖和还原糖的含量,降低可滴定酸含量,改善果实风味,提高果实品质和经济效益;其中每株增施7.5 kg有机肥效果最佳,与CK相比,第1批和第2批果实的单果质量、果实纵径和横径分别增长了32.48%和20.77%、31.70%和33.97%、25.43%和24.58%,可溶性固形物、Vc、可溶性糖和还原糖分别提高了14.95%和25.76%、56.58%和57.55%、56.93%和53.23%、40.87%和50.54%,可滴定酸含量降低了25.00%和19.35%,总利润提高了55.46%。

| Abstract: | The study was aimed to explore the effects of adding organic fertilizers on the yield and quality of two harvests of guava fruits a year with chemical fertilizers, and to provide a basis for scientific fertilization of guava. The effects on the appearance, yield, quality and economic benefits of guava fruit of ‘Hongxiang No. 1’ by the application of chemical fertilizer (CK), CK + organic fertilizer 2.5 kg/plant, CK + organic fertilizer 5.0 kg/plant, CK + organic fertilizer 7.5 kg/plant and CK + organic fertilizer 10.0 kg/plant were studied. The combined application of organic fertilizer increased the quality of fruit, increased the longitudinal diameter, transversed diameter and fruit shape index, improved the appearance of the fruit, increased the yield, and at the same time increased the contents of soluble solids, Vc, soluble sugar and reducing sugar, reduced the content of titratable acid, improved economic benefits. Among them, the effect of applying 7.5 kg of organic fertilizer per plant is the best. The quality of the first and second harvest fruit, the vertical and horizontal diameter of the fruit increased by 32.48% and 20.77%, 31.70% and 33.97%, respectively, the content of soluble solids, Vc, soluble sugar and reducing sugar increased by 14.95% and 25.76%, 56.58% and 57.55%, 56.93% and 53.23%, 40.87% and 50.54%, respectively, the the content of titratable acid content reduced by 25.00% and 19.35%, and the total profit increased by 55.46% over CK. |
