【摘要】 以沙糖桔为材料,在果实转色期喷施"喷树增产耐贮剂".与对照组相比,该处理可增加果实成熟期可溶性糖和可溶性固形物的含量,增幅分别为8.5%和8.9%;同时,显著减少了维生素C的降幅,比对照组低了16.26%.经喷施耐贮剂处理60 d后,处理组比对照组可溶性糖含量增加了8%,可溶性固形物增加了10%,维生素C增加了20%.果实与果径生长动态分析表明:经"喷树增产耐贮剂"处理后21～40 d的果径生长速率与对照组相比差异显著,采果时经过处理的果树单果质量显著增加,采果时的落果率显著减少.更多还原

【Abstract】 When the green-colored Citrus reticulata Banco(cv.’Shatangju’) fruits was transforming into orange,the aqueous solution of "Foliar Reagents for Enhancing Fruits Yield and Storage" was sprayed on the trees.During the fruits maturation,compared with the control group,the treatment significantly enhanced the increasing rates of soluble sugar and soluble solids by 8.5% and 8.9% respectively;and reduced the dropping rate of vitamin C content by 16.26%.60 d after the treatment,the contents of soluble sugar and soluble solids and vitamin C in the treated fruits were increased by 8% and 10% and 20% than those of untreated fruits respectively.The dynamic analysis of fruits and fruit diameters shows that the treatment of spraying also increased the growth rate of fruit diameters after 21 d to 40 d of treatment,significantly increased the single fruit quality,obviously reduced the drop rate of fruits during the maturation period.更多还原
